TL;DR – I have no idea why this is happening as frequently as it is, what’s causing it, or how to stop it. So I’m using AFP for the moment.
I run a Plex server on my Mac mini 2018 running macOS Catalina 10.15.6. I have all of my media stored on a QNAP TS-831X NAS running QTS 18.104.22.1680 with volumes connected to macOS over SMB. This has worked reasonably well with Catalina for the last year (?) or so, but with the latest Catalina update I’ve had frequent (as in every few hours) disconnections from the shares. I’ve tried a variety of fixes, and thought I’d document them here. None of them really worked, so what I’m hoping is that someone with solid macOS chops will be able to tell me what I’m doing wrong.
QNAP and SMB
I made sure I was running the latest QNAP firmware version. I noticed in the latest release notes for 22.214.171.1241 that it fixed a problem where “[u]sers could not mount NAS shared folders and external storage devices at the same time on macOS via SMB”. This wasn’t quite the issue I was experiencing, but I was nonetheless hopeful. This was not the case. This thread talked about SMB support levels. I was running my shares with support for SMB 2.1 through 3.0. I’ve since changed that to 3.0 only. No dice.
This guy on this thread thinks he’s nailed it. He may have, but not for me. I’ve included some of the text for reference below.
Server Performance Mode
The description reads:
Performance mode changes the system parameters of your Mac. These changes take better advantage of your hardware for demanding server applications. A Mac that needs to run high-performance services can turn on performance mode to dedicate additional system resources for server applications.
1 – First check to see if server performance mode is enabled on your machine using this Terminal command. You should see the command return serverperfmode=1 if it is enabled.
2 – If you do not see serverperfmode=1 returned, enter this following line of code to enable it. (I recommend rebooting your system afterwards)
sudo nvram boot-args="serverperfmode=1 $(nvram boot-args 2>/dev/null | cut -f 2-)"
I’ve also tried changing the power settings on the Mac mini, and disabled power nap. No luck there either. I’ve also tried using the FQDN of the NAS as opposed to the short name of the device when I map the drives. Nope, nothing.
My QNAP still supports Apple File Protocol, and it supports multiple protocols for the same share. So I turned on AFP and mapped the drives that way. I’m pleased to say that I haven’t had the shares disconnect since (and have thus had a much smoother Plex experience), but I’m sad to say that this is the only solution I have to offer for the moment. And if your storage device doesn’t support AFP? Sod knows. I haven’t tried doing it via NFS, but I’ve heard reports that NFS was its own special bin fire in recent versions of Catalina. It’s an underwhelming situation, and maybe one day I’ll happen across the solution. And I can share it here and we can all do a happy dance.
Welcome to Random Short Take #39. Not a huge amount of players have worn 39 in the NBA, and I’m not going to pretend I’m any real fan of The Dwightmare. But things are tough all around, so let’s remain optimistic and push through to number 40. Anyway let’s get random.
- VeeamON 2020 was online this week, and Anthony Spiteri has done a great job of summarising the major technical session announcements here.
- I’ve known Howard Marks for a while now, and always relish the opportunity to speak with him when I can. This post is pretty hilarious, and I’m looking forward to reading the followup posts.
- This is a great article from Alastair Cooke on COVID-19 and what En-Zed has done effectively to stop the spread. It was interesting to hear his thoughts on returning to the US, and I do agree that it’s going to be some time until I make the trip across the Pacific again.
- Sometimes people get crazy ideas about how they might repurpose some old bits of technology. It’s even better when they write about their experiences in doing so. This article on automating an iPod Hi-Fi’s volume control over at Six Colors was fantastic.
- Chris M. Evans put out a typically thought-provoking piece on data migration challenges recently that I think is worth checking out. I’ve been talking a lot to customers that are facing these challenges on a daily basis, and it’s interesting to see how, regardless of the industry vertical they operate in, it’s sometimes just a matter of the depth varying, so to speak.
- I frequently bump into Ray Lucchesi at conferences, and he knows a fair bit about what does and doesn’t work. This article on his experiences recently with a number of virtual and online conferences is the epitome of constructive criticism.
- Speaking of online conferences, the Australian VMUG UserCon will be virtual this year and will be held on the 30th July. You can find out more and register here.
- Finally, if you’ve spent any time with me socially, you’ll know I’m a basketball nut. And invariably I’ll tell you that Deftones is may favouritest band ever. So it was great to come across this article about White Pony on one of my favourite sports (and popular culture) websites. If you’re a fan of Deftones, this is one to check out.
This post is really about the boring stuff I do when I have a day off and isn’t terribly exciting. TL;DR I had some problems upgrading to Catalina, and had to start from scratch.
I’ve had an Apple Mac since around 2008. I upgraded from a 24″ iMac to a 27″ iMac and was super impressed with the process of migrating between machines, primarily because of Time Machine’s ability to recover settings, applications, and data in a fairly seamless fashion. I can’t remember what version of macOS I started with (maybe Leopard?), but I’ve moved steadily through the last few versions with a minimal amount of fuss. I was running Mojave on my iMac late last year when I purchased a refurbished 2018 Mac mini. At the time, I decided not to upgrade to Catalina, as I’d had a few issues with my work laptop and didn’t need the aggravation. So I migrated from the iMac to the Mac mini and kept on keeping on with Mojave.
Fast forward to a April this year, and the Mac mini gave up the ghost. With Apple shutting down its stores here in response to COVID-19, it was a 2 week turnaround at the local repair place to get the machine fixed. In the meantime, I was able to use Time Machine to load everything on a 2012 MacBook Pro that was being used sparingly. It was a bit clunky, but had an internal SSD and 16GB of RAM, so it could handle the basics pretty comfortably. When the Mac mini was repaired, I used Time Machine once again to move everything back. It’s important to note that this is everything (settings, applications, and data) that had been accumulated since 2008. So there’s a bit of cruft associated with this build. A bunch of 32-bit applications that I’d lost track of, widgets that were no longer really in use, and so on.
The Big Update
I took the day off on Friday last week. I’d been working a lot of hours since COVID-19 restrictions kicked in here, and I’d been filling my commuting time with day job work (sorry blog!). I thought it would be fun to upgrade the Mac mini to Catalina. I felt that things were in a reasonable enough state that I could work with what it had to offer, and I get twitchy when there’s an upgrade notification on the Settings icon. Just sitting there, taunting me.
I downloaded the installer and pressed on. No dice, my system volume wasn’t formatted with APFS. How could this be? Well, even though APFS has been around for a little while now, I’d been moving my installation across various machines. At the time when the APFS conversion was part of the macOS upgrade, I was running an iMac with a spinning disk as the system volume, and so it never prompted to do that upgrade. When I moved to the Mac mini, I didn’t do any macOS upgrade, so I guess it just kept working with the HFS+ volume. It seems a bit weird that Catalina doesn’t offer a workaround for this, but I may just have been looking in the wrong place. Now, there was a lot of chatter in the forums about rebooting into Recovery Mode and converting the drive to an APFS volume. No matter what I tried, I was unable to do this effectively (either using the Recovery Mode console with Mojave or with Catalina booting from USB). I followed articles like this one but just didn’t have the same experience. And when I erased the system drive and attempted to recover from Time Machine backups, it would re-erase the volume as HFS+. So, I don’t know, I guess I’m an idiot. The solution that finally worked for me was to erase the drive, format it as APFS, install Mojave from scratch, and recover from a Time Machine backup. Unfortunately, though, this seemed to only want to transfer around 800KB of settings data. The normal “wait a few hours while we copy your stuff” just didn’t happen. Sod knows why, but what I did know was that I was really wasting my day off with this stuff.
I also ran in to an issue trying to do the installation from USB. You can read about booting from external devices and the T2 security chip here, here, and here. I lost patience with the process and took a different approach.
Is That So Bad?
Not really. I have my Photos library and iTunes media on a separate volume. I have one email account that we have used POP with over the years, but I installed Thunderbird, recovered the profile from my Time Machine data, and modified profiles.ini to point to that profile (causing some flashbacks to my early days on a help desk supporting a Netscape user base). The other thing I had to do was recover my Plex database. You can read more on that here. It actually went reasonably well. I’d been storing my iPhone backups on a separate volume too, and had to follow this process to relocate those backup files. Otherwise, Microsoft, to their credit, has made the reinstallation process super simple with Microsoft 365. Once I had most everything setup again, I was able to perform the upgrade to Catalina.
If this process sounds like it was a bit of a pain, it was. I don’t know that Apple has necessarily dropped the ball in terms of usability in the last few years, but sometimes it feels like it. I think I just had really high expectations based on some good fortune I’d enjoyed over the past 12 years. I’m not sure what the term is exactly, but it’s possible that because I’ve invested this much money in a product, I’m more forgiving of the issues associated with the product. Apple has done a great job historically of masking the complexity of technology from the end user. Sometimes, though, you’re going to come across odd situations that potentially push you down an odd path. That’s what I tell myself anyway as I rue the time I lost on this upgrade. Was anyone else’s upgrade to Catalina this annoying?
Welcome to Random Short Take #32. Lot of good players have worn 32 in the NBA. I’m a big fan of Magic Johnson, but honourable mentions go to Jimmer Fredette and Blake Griffin. It’s a bit of a weird time around the world at the moment, but let’s get to it.
- Veeam 10 was finally announced a little while ago and is now available for deployment. I work for a service provider, and we use Veeam, so this article from Anthony was just what I was after. There’s a What’s New article from Veeam you can view here too.
- I like charts, and I like Apple laptops, so this chart was a real treat. The lack of ports is nice to look at, I guess, but carrying a bag of dongles around with me is a bit of a pain.
- VMware recently made some big announcements around vSphere 7, amongst other things. Ather Beg did a great job of breaking down the important bits. If you like to watch videos, this series from VMware’s recent presentations at Tech Field Day 21 is extremely informative.
- Speaking of VMware Cloud Foundation, Cormac Hogan recently wrote a great article on getting started with VCF 4.0. If you’re new to VCF – this is a great resource.
- Leaseweb Global recently announced the availability of 2nd Generation AMD EPYC powered hosts as part of its offering. I had a chance to speak with Mathijs Heikamph about it a little while ago. One of the most interesting things he said, when I questioned him about the market appetite for dedicated servers, was “[t]here’s no beating a dedicated server when you know the workload”. You can read the press release here.
- This article is just … ugh. I used to feel a little sorry for businesses being disrupted by new technologies. My sympathy is rapidly diminishing though.
- There’s a whole bunch of misinformation on the Internet about COVID-19 at the moment, but sometimes a useful nugget pops up. This article from Kieren McCarthy over at El Reg delivers some great tips on working from home – something more and more of us (at least in the tech industry) are doing right now. It’s not all about having a great webcam or killer standup desk.
- Speaking of things to do when you’re working at home, JB posted a handy note on what he’s doing when it comes to lifting weights and getting in some regular exercise. I’ve been using this opportunity to get back into garage weights, but apparently it’s important to lift stuff more than once a month.
Welcome to Random Short Take #31. Lot of good players have worn 31 in the NBA. You’d think I’d call this the Reggie edition (and I appreciate him more after watching Winning Time), but this one belongs to Brent Barry. This may be related to some recency bias I have, based on the fact that Brent is a commentator in NBA 2K19, but I digress …
- Late last year I wrote about Scale Computing’s big bet on a small form factor. Scale Computing recently announced that Jerry’s Foods is using the HE150 solution for in-store computing.
- I find Plex to be a pretty rock solid application experience, and most of the problems I’ve had with it have been client-related. I recently had a problem with a server update that borked my installation though, and had to roll back. Here’s the quick and dirty way to do that on macOS.
- Here’s are 7 contentious thoughts on data protection from Preston. I think there are some great ideas here and I recommend taking the time to read this article.
- I recently had the chance to speak with Michael Jack from Datadobi about the company’s announcement about its new DIY Starter Pack for NAS migrations. Whilst it seems that the professional services market for NAS migrations has diminished over the last few years, there’s still plenty of data out there that needs to be moved from on box to another. Robocopy and rsync aren’t always the best option when you need to move this much data around.
- There are a bunch of things that people need to learn to do operations well. A lot of them are learnt the hard way. This is a great list from Jan Schaumann.
- Analyst firms are sometimes misunderstood. My friend Enrico Signoretti has been working at GigaOm for a little while now, and I really enjoyed this article on the thinking behind the GigaOm Radar.
- Nexsan recently announced some enhancements to its “BEAST” storage platforms. You can read more on that here.
- Alastair isn’t just a great writer and moustache aficionado, he’s also a trainer across a number of IT disciplines, including AWS. He recently posted this useful article on what AWS newcomers can expect when it comes to managing EC2 instances.

Not VxBlock 2.0?
Dell EMC describes PowerOne as “all-in-one autonomous infrastructure”. It’s converged infrastructure, meaning your storage, compute, and networking are all built into the rack. It’s a transportation-tested package and fully assembled when it ships. When it arrives, you can plug it in, fire up the API, and be up and going “within a few hours”.
Trey Layton is no stranger to Vblock / VxBlock, and he was very clear with the delegates that PowerOne is not replacing VxBlock. After all, VxBlock lets them sell Dell EMC external storage into Cisco UCS customers.
So What Is It Then?
It’s a rack or racks full of gear. All of which is now Dell EMC gear. And it’s highly automated and has some proper management around it too.

So what’s in those racks?
- PowerMax Storage – World’s “fastest” storage array
- PowerEdge MX – industry leading compute
- PowerSwitch – Declarative system fabric
- PowerOne Controller – API-powered automation engine
- Zero-touch SAN config
- Discovery / inventory of storage resources
- Dynamically create storage volumes for clusters
- Intelligent load balancing
PowerEdge MX Compute
- Dynamically provision compute resources into clusters
- Automated chassis expansion
- Telemetry aggregation
- Kinetic infrastructure
- Switches are 32Gbps
- 98% reduction in network configuration steps
- System fabric visibility and lifecycle management
- Intent-based automated deployment and provision
- PowerSwitch open networking
- Highly automates 1000s of tasks
- Powered by Kubernetes and Ansible
- Delivers next-gen autonomous outcomes via robust API capabilities
From a scalability perspective, you can go to 275 nodes in a pod, and you can look after up to 32 pods (I think). The technical specifications are here.
Thoughts and Further Reading
Converged infrastructure has always been an interesting architectural choice for the enterprise. When VCE first came into being 10+ years ago via Acadia, delivering consistent infrastructure experiences in the average enterprise was a time-consuming endeavour and not a lot of fun. It was also hard to do well. VCE changed a lot of that with Vblock, but you paid a premium. The reason you paid that premium was that VCE did a pretty decent job of putting together an architecture that was reliable and, more importantly, supportable by the vendor. It wasn’t just the IP behind this that made it successful though, it was the effort put into logistics and testing. And yes, a lot of that was built on the strength of spreadsheets and the blood, sweat and tears of the deployment engineers out in the field.
PowerOne feels like a very different beast in this regard. Dell EMC took us through a demo of the “unboxing” experience, and talked extensively about the lifecycle of the product. They also demonstrated many of the automation features included in the solution that weren’t always there with Vblock. I’ve been responsible for Vblock environments over the years, and a lot of the lifecycle management activities were very thoroughly documented, and extremely manual. PowerOne, on the other hand, doesn’t look like it relies extensively on documentation and spreadsheets to be managed effectively. But maybe that’s just because Trey and the team were able to demonstrate things so effectively.
So why would the average enterprise get tangled up in converged infrastructure nowadays? What with all the kids and their HCI solutions, and the public cloud, and the plethora of easy to consume infrastructure solutions available via competitive consumption models? Well, some enterprises don’t like relying on people within the organisation to deliver solutions for mission critical applications. These enterprises would rather leave that type of outcome in the hands of one trusted vendor. But they might still want that outcome to be hosted on-premises. Think of big financial institutions, and various government agencies looking after very important things. These are the kinds of customers that PowerOne is well suited to.
That doesn’t mean that what Dell EMC is doing with PowerOne isn’t innovative. In fact I think what they’ve managed to do with converged infrastructure is very innovative, within the confines of converged infrastructure. This type of approach isn’t for everyone though. There’ll always be organisations that can do it faster and cheaper themselves, but they may or may not have as much at stake as some of the other guys. I’m curious to see how much uptake this particular solution gets in the market, particularly in environments where HCI and public cloud adoption is on the rise. It strikes me that Dell EMC has turned a corner in terms of system integration too, as the out of the box experience looks really well thought out compared to some of its previous attempts at integration.
Welcome to Random Short Take #30. You’d think 30 would be an easy choice, given how much I like Wardell Curry II, but for this one I’m giving a shout out to Rasheed Wallace instead. I’m a big fan of ‘Sheed. I hope you all enjoy these little trips down NBA memory lane. Here we go.
- Veeam 10’s release is imminent. Anthony has been doing a bang up job covering some of the enhancements in the product. This article was particularly interesting because I work in a company selling Veeam and using vCloud Director.

- Remember Retrospect? They were acquired by StorCentric recently. I hadn’t thought about them in some time, but they’re still around, and celebrating their 30th anniversary. Read a little more about the history of the brand here.
- Sometimes size does matter. This article around deduplication and block / segment size from Preston was particularly enlightening.
- This article from Russ had some great insights into why it’s not wise to entirely rule out doing things the way service providers do just because you’re working in enterprise. I’ve had experience in both SPs and enterprise and I agree that there are things that can be learnt on both sides.
- This is a great article from Chris Evans about the difficulties associated with managing legacy backup infrastructure.

Here are some links to some random news items and other content that I recently found interesting. You might find them interesting too. Episode 17 – am I over-sharing? There’s so much I want you to know about.
- I seem to always be including a link from the Backblaze blog. That’s mainly because they write about things I’m interested in. In this case, they’ve posted an article discussing the differences between availability and durability that I think is worth your time.
- Speaking of interesting topics, Preston posted an article on NetWorker Pools with Data Domain that’s worth looking at if you’re into that kind of thing.
- Maintaining the data protection theme, Alastair wrote an interesting article titled “The Best Automation Is One You Don’t Write” (you know, like the best IO is one you don’t need to do?) as part of his work with Cohesity. It’s a good article, and not just because he mentions my name in it.
- I recently wanted to change the edition of Microsoft Office I was using on my MacBook Pro and couldn’t really work out how to do it. In the end, the answer is simple. Download a Microsoft utility to remove your Office licenses, and then fire up an Office product and it will prompt you to re-enter your information at that point.
- This is an old article, but it answered my question about validating MD5 checksums on macOS.
- Excelero have been doing some cool stuff with Imperial College London – you can read more about that here.
- Oh hey, Flixster Video is closing down. I received this in my inbox recently: “[f]ollowing the announcement by UltraViolet that it will be discontinuing its service on July 31, 2019, we are writing to provide you notice that Flixster Video is planning to shut down its website, applications and operations on October 31, 2019”. It makes sense, obviously, given UltraViolet’s demise, but it still drives me nuts. The ephemeral nature of digital media is why I still have a house full of various sized discs with various kinds of media stored on them. I think the answer is to give yourself over to the streaming lifestyle, and understand that you’ll never “own” media like you used to think you did. But I can’t help but feel like people outside of the US are getting shafted in that scenario.
- In keeping up with the “random” theme of these posts, it was only last week that I learned that “Television, the Drug of the Nation” from the very excellent album “Hypocrisy Is the Greatest Luxury” by The Disposable Heroes of Hiphoprisy was originally released by Michael Franti and Rono Tse when they were members of The Beatnigs. If you’re unfamiliar with any of this I recommend you check them out.
