Hi NUNIN,
Usually when an NFS Storage Domain is in "preparing for maintenance" status, it is because one of the Hosts encounter a problem while un mounting the storage domain.
Can you please add the engine logs and also the VDSM logs of the hosts you are using in the Data Center.
while gathering all the logs you could try also the following actions:
1. Since you wrote that you do see an audit log indicating the operation succeed, maybe it could also be a refresh problem in the GUI.
Could you try to switch tabs in the GUI (For example to peak the "Virtual Machine" main tab and switch back to the Storage Domain tab)
If that is not helping, try for restart your engine service (guessing it also could be an issue of the monitor Storage Domains)
Please let me know if there is any difference
Regards,
Maor
