vinum question: how could one correctly delete vinum module?
Dear colleagues, [I'm under 4-STABLE] What is the correct sequence to delete existing vinum module (for example, raid10) and do *not* use -f flags for vinum? 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 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) 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? Thanks in advance.

Use "vinum resetconfig". You will loose all of your data, but if I understand your question correctly, this is the command to use. If you want to remove individual objects, use the rm command. Take a look at the vinum man page, it is quite useful.

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 MBThese 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.
