Basically, I created a Raid5 Stripeset: drive ibm120ad2 device /dev/ad2s1e drive ibm120ad5 device /dev/ad5s1e drive ibm120ad7 device /dev/ad7s1e volume raid5 plex org raid5 512k sd length 0s drive ibm120ad2 sd length 0s drive ibm120ad5 sd length 0s drive ibm120ad7 I ran saveconfig, to save the configuration to disk. I then proceeded to move quite a lot of data onto the raid5 volume. Then some time later, I reinstalled FreeBSD. To restore the raid5 volume, I ran: read disk /dev/ad2s1e /dev/ad5s1e /dev/ad7s1e Upon doing a list, it gives: vinum -> list 3 drives: D ibm120ad2 State: up Device /dev/ad2s1es1a Avail: 117796/117796 MB (100%) D ibm120ad5 State: up Device /dev/ad5s1es1a Avail: 0/117796 MB (0%) D ibm120ad7 State: up Device /dev/ad7s1es1a Avail: 117796/117796 MB (100%) D *invalid* State: referenced Device Avail: 0/0 MB 1 volumes: V raid5 State: up Plexes: 1 Size: 230 GB 1 plexes: P raid5.p0 R5 State: corrupt Subdisks: 3 Size: 230 GB 3 subdisks: S raid5.p0.s0 State: up PO: 0 B Size: 115 GB S raid5.p0.s1 State: stale PO: 512 kB Size: 115 GB S raid5.p0.s2 State: stale PO: 1024 kB Size: 115 GB Subdisk s0 shows as present: vinum -> list -V raid5.p0.s0 Subdisk raid5.p0.s0: Size: 123518582784 bytes (117796 MB) State: up Plex raid5.p0 at offset 0 (0 B) Drive ibm120ad5 (/dev/ad5s1es1a) at offset 135680 (132 kB) However subdisks s1 and s2 show as missing: vinum -> list -V raid5.p0.s1 Subdisk raid5.p0.s1: Size: 123518582784 bytes (117796 MB) State: stale Plex raid5.p0 at offset 524288 (512 kB) Drive *invalid* (*missing*) at offset 135680 (132 kB) vinum -> list -V raid5.p0.s2 Subdisk raid5.p0.s2: Size: 123518582784 bytes (117796 MB) State: stale Plex raid5.p0 at offset 1048576 (1024 kB) Drive *invalid* (*missing*) at offset 135680 (132 kB) They seem to have lost their drivename, so don't know which drive represents them. I have tried doing various things, such as changing the read disk options, ie "read disk /dev/ad2" etc, but all had pretty much the same result. I am at a loss for what to do next. Initially I did attempt to mount the raid5 volume, doing an ls on the mount point showed the correct directories, however when I attempted to cd and then ls into them, the kernel paniced. I since haven't been able to mount the raid5 volume, I get "mount: /dev/vinum/raid5 on /raid5: incorrect super block". I am concerned that I have somehow damaged the stripeset. Unfortunately backup media for backing up 240Gb's worth of data is rather expensive compared to how cheap disks are at the moment, and as such I only have backups of the critical data, so any help will be greatly appreciated! Many thanks.
