We recently lost an NFS server. It was used to export a drive with ISO files for use in XenServer patching / updating / etc. The server has been replaced but the mounted drive can't be removed from XenCenter or via the command line.
What I've tried:
(using these instructions):
- xe sr-list name-label=<NFS mount>
- xe pbd-list sr-uuid=<UUID of volume>
- xe pbd-unplug uuid=<UUID of mount point>
Error code: SR_BACKEND_FAILURE_140
Error parameters: , Incorrect DNS name, unable to resolve.,
The volume no longer appears in /etc/mtab but Xen refuses to let go of it.
Suggestions on where else to look?
