I think your terminology is incorrect. To delete an existing Vinum module under release 4, you would normally do: # rm /modules/vinum.ko To unload the module from the kernel, you would first quiesce the Vinum system and then do: # vinum stop But I'd guess that this isn't what you want to do. > in my case t is raid10 vovume: > > vinum -> l -r t > V t State: up Plexes: 2 Size: 8191 MB > P t.p0 S State: up Subdisks: 2 Size: 8191 MB > P t.p1 S State: up Subdisks: 2 Size: 8191 MB > S t.d0 State: up PO: 0 B Size: 4095 MB > S t.d8 State: up PO: 260 kB Size: 4095 MB > S t.d2 State: up PO: 0 B Size: 4095 MB > S t.d10 State: up PO: 260 kB Size: 4095 MB These subdisk names are very confusing. > umount /dev/vinum/t > vinum stop t (ok) > vinum stop t.p0 <- this operation silently puts t up, and sets t.p0 faulty > vinum stop t (ok) > vinum stop t.p1 > > Last comment leads to error > > Can't stop t.p1: Device busy (16) Why do you want to stop a plex? > Final state of objects are > > vinum -> l -r t > V t State: down Plexes: 2 Size: 8191 MB > P t.p0 S State: faulty Subdisks: 2 Size: 8191 MB > P t.p1 S State: up Subdisks: 2 Size: 8191 MB > S t.d0 State: down PO: 0 B Size: 4095 MB > S t.d8 State: down PO: 260 kB Size: 4095 MB > S t.d2 State: up PO: 0 B Size: 4095 MB > S t.d10 State: up PO: 260 kB Size: 4095 MB > > Any suggestions? should I dig into vinum sources to track this down? Well, I think you know the answer: use the -f flag. But maybe I'm misunderstanding the question.
