when your triggering vol offline command can you check what it is logging in the messages file..?

[yvgr79in]

no message on messages after the vol offline command only terminal it came up with above stated message. Nothing fishy on messages to offline this vol.

can you check :

set advanced or diag

filer*>ndmpd status

filer>backup status

if no NDMP or backup activity then best to do the failover & failback then give a try..(might be a hung process is not allowing to delete it)
