VMware – Unmounting NFS Datastores From The CLI

This is a short article, but hopefully useful. I did a brief article a while ago linking to some useful articles about using NFS with VMware vSphere. I recently had to do some maintenance on one of the arrays in our lab and I was having trouble unmounting the datastores using the vSphere client. I used some of the commands in this KB article (although I don’t have SIOC enabled) to get the job done instead.

The first step was to identify if any of the volumes were still mounted on the individual host.

[root@esxihost:~] esxcli storage nfs list
Volume Name  Host            Share                 Accessible  Mounted  Read-Only   isPE  Hardware Acceleration
-----------  --------------  --------------------  ----------  -------  ---------  -----  ---------------------
Pav05        10.300.300.105  /nfs/GB000xxxxxbbf97        true     true      false  false  Not Supported
Pav06        10.300.300.106  /nfs/GB000xxxxxbbf93        true     true      false  false  Not Supported
Pav01        10.300.300.101  /nfs/GB000xxxxxbbf95        true     true      false  false  Not Supported

In this case there are three datastores that I haven’t been able to unmount.

[root@esxihost:~] esxcli storage nfs remove -v Pav05
[root@esxihost:~] esxcli storage nfs remove -v Pav06
[root@esxihost:~] esxcli storage nfs remove -v Pav01

Now there should be no volumes mounted on the host.

[root@esxihost:~] esxcli storage nfs list
[root@esxihost:~]

See, I told you it would be quick.
