Reset host scratch locations

[JDMils_Interact]

I'm trying to remove the only 2 datastores connected to a host so that I can set the host as a SPARE to use later in another cluster.

Host is:
VMware ESXi, 7.0.3, 21930508
UCSB-B200-M4

Cluster-level HA is turned off.
Host \ Virtual Machines \ Swap File Location  = Virtual machine directory
Host \ System \ Advanced System Settings \ Syslog.global.logDir  = [] /scratch/log
Host \ System \ Advanced System Settings \ ScratchConfig.ConfiguredScratchLocation = /vmfs/volumes
Host \ System \ Advanced System Settings \ ScratchConfig.CurrentScratchLocation = /vmfs/volumes

I set these to /vmfs/volumes as I had no other datastores to store them on.

When I try to unmount Datastore02, I get the error:

 

 

The resource 'Datastore02' is in use.
Cannot remove datastore 'Datastore02' because "local swap is enabled on it". Correct the problem and retry the operation.

 

 

I'm not sure what else to try?

 

 

[root@MyHost01:/vmfs/volumes/62e1d2e5-906ed05a-4270-01234567890] esxcfg-nas -l
Datastore04 is /Datastore03/qt_0004 from 172.10.16.12 mounted available
Datastore02 is /Datastore02/qt_0002 from 172.10.16.12 mounted available

esxcfg-nas -d cmsinf_nfs_vmdata_t1000_pp_02
NAS volume cmsinf_nfs_vmdata_t1000_pp_02 deleted.

/etc/init.d/hostd restart
/etc/init.d/vpxa restart

esxcfg-nas -l
Datastore04 is /Datastore03/qt_0004 from 172.10.16.12 mounted available

reboot -f

 

 

After rebooting the host, the deleted datastore is back!?

I then try to unmount the last datastore Datastore04 however I get the error:

 

 

Unmount NFS datastore failed!

The resource 'cmsinf_nfs_vmdata_t1000_pp_04' is in use.

 

 

How do I find where it is in use?

@JDMils_Interact Did you ever resolve this issue?

[JDMils_Interact]

I did fix the issue. I tried the "esxcfg-nas -l" method above which did not work and I think I had to go into the VC DB to remove the datastore from vCenter. I don't remember the exact fix tho.
