ESXi 5.5 VMFS3
I'm trying to delete or unmount a datastore but both are failing with below error messages.
UNMOUNT. - Out of the 5 hosts in cluster it is unmounted from 4 while it's still mounted on one host & gives below error
Call "HostStorageSystem.UnmountVmfsVolume" for object "storageSystem-3994" on vCenter Server "xyz" failed.
Cannot unmount volume 'Datastore Name: abc VMFS uuid: 507978c7-f56a954c-b170-782bcb507614' because file system is busy. Correct the problem and retry the operation.
DELETE - if trying to delete it's giving me below error.
Call "HostDatastoreSystem.RemoveDatastore" for object "datastoreSystem-3994" on vCenter Server "xyz" failed.
Cannot remove datastore 'Datastore Name: abc VMFS uuid: 507978c7-f56a954c-b170-782bcb507614' because file system is busy. Correct the problem and retry the operation.
I browsed through the datastore, there's only folder named .vSphere-HA while if I check the datastore hearbeating in HA properties, this datastore is not a part of Datastore heartbeats as well.
Tried restarting mgmt services - Didn't work
Tried disabling HA & then deleting/unmounting datastore - Didn't work
Triedhttp://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2069171 - Didn't work
Rebooting the host would be last option, but I'm looking for a fix on this.
