Removing Inaccessible NFS datastore in vSphere 6.7.0

Hi,

I have a NFS datastore that is no longer accessible. Didn't have anything on it but I can't unmount it.  When I do I get the message:

The resource 'BU1' is in use.
Cannot remove datastore 'BU1' because "system swap is enabled on it". Correct the problem and retry the operation.

I don't recall putting anything on it, much less enabling it for system swap.  ?

6.7.0 w/ VCSA.

Hi,

in fact it seems to be actually used by something, preventing unmount or remove

Some things to check which could help :

- ESX / Configure / advanced settings > look at syslog.global.logdir and mostly scratchconfig settings
If this last one point t your nfs datastore, change it and reboot ESX, then unmount/remove datastore
- ESX / Configure / VM / Swap file location
- ESX / Configure / System / System Swap
...

What is the precise error message? is it really system swap is enabled on it ? I never seen this one, generally it is more ressource/device is busy generic message

Hi,

Sorry for the delay; injured spouse.

The exact error message is: "The resource 'BU1' is in use.
Cannot remove datastore 'BU1' because "system swap is enabled on it". Correct the problem and retry the operation."

System Swap file has:

    Can use datastore: 970Pro
    Can use host cache
    Can use datastore specified by host for swap files

VM Swap file location is:

     Virtual machine directory

The syslog.global.logdir value is  [] /scratch/log

The ConfiguredScratchLocation and CurrentScratchLocation both point to /vmfs/volumes/5bca7765-e61b9be8-a031-ac1f6b19f7c0
which isn't the location of the missing NFS volume (ds:///vmfs/volumes/6a3eed65-7142512f/).
