Hi, We have a gvinum raid-5 volume that that we had to replace a disk on and after that we cant get the new subdisk starting. Here are the things we did: 1: Replace disk and boot singleuser to fdisk and lable new disk: gvinum -> list 5 drives: D disk4 State: up /dev/da5s1a A: 0/17492 MB (0%) D disk3 State: up /dev/da4s1a A: 0/17492 MB (0%) D disk2 State: up /dev/da3s1a A: 0/17492 MB (0%) D disk1 State: up /dev/da2s1a A: 0/17492 MB (0%) 1 volume: V imap State: up Plexes: 1 Size: 68 GB 1 plex: P imap.p0 R5 State: up Subdisks: 5 Size: 68 GB 5 subdisks: S imap.p0.s0 State: up D: disk1 Size: 17 GB S imap.p0.s1 State: up D: disk2 Size: 17 GB S imap.p0.s2 State: up D: disk3 Size: 17 GB S imap.p0.s3 State: up D: disk4 Size: 17 GB S imap.p0.s4 State: up D: disk5 Size: 17 GB After fixing the new disk partition we did a saveconfig and reboot: gvinum -> list 5 drives: D disk5 State: up /dev/da6s1a A: 0/17492 MB (0%) D disk4 State: up /dev/da5s1a A: 0/17492 MB (0%) D disk3 State: up /dev/da4s1a A: 0/17492 MB (0%) D disk2 State: up /dev/da3s1a A: 0/17492 MB (0%) D disk1 State: up /dev/da2s1a A: 0/17492 MB (0%) 1 volume: V imap State: up Plexes: 1 Size: 68 GB 1 plex: P imap.p0 R5 State: up Subdisks: 5 Size: 68 GB 5 subdisks: S imap.p0.s4 State: stale D: disk5 Size: 17 GB S imap.p0.s3 State: up D: disk4 Size: 17 GB S imap.p0.s2 State: up D: disk3 Size: 17 GB S imap.p0.s1 State: up D: disk2 Size: 17 GB S imap.p0.s0 State: up D: disk1 Size: 17 GB Tried start on plex and subdisk, nnot working. Finally, to get plex into degraded mode we did a setstate down imap.p0.s4. gvinum -> list 5 drives: D disk5 State: up /dev/da6s1a A: 0/17492 MB (0%) D disk4 State: up /dev/da5s1a A: 0/17492 MB (0%) D disk3 State: up /dev/da4s1a A: 0/17492 MB (0%) D disk2 State: up /dev/da3s1a A: 0/17492 MB (0%) D disk1 State: up /dev/da2s1a A: 0/17492 MB (0%) 1 volume: V imap State: up Plexes: 1 Size: 68 GB 1 plex: P imap.p0 R5 State: degraded Subdisks: 5 Size: 68 GB 5 subdisks: S imap.p0.s4 State: down D: disk5 Size: 17 GB S imap.p0.s3 State: up D: disk4 Size: 17 GB S imap.p0.s2 State: up D: disk3 Size: 17 GB S imap.p0.s1 State: up D: disk2 Size: 17 GB S imap.p0.s0 State: up D: disk1 Size: 17 GB and here we are. Start on volume or plex give errno 16, start on subdisk gives can't start: cannot start 'imap.p0.s4' - not yet supported. Can't find any descriptions of the proper way to do disk replacement, so if this is wrong, I'd love to get updated. And how do we get the current situation upa nd running?
