Rescuing broken RAID5 gvinum volume
I'm hoping that someone can help with this problem. I have a RAID5 gvinum volume that was working and then encountered a few problems which I responded to by running fsck. Unfortunately, that was just the beginning of my troubles.
The system is currently running FreeBSD 7.3 release, but was running FreeBSD 8.0 release (that may in fact be part of my problems). Here's the details (everything looks fine and I've rebuilt the parity on the drives): Code:
gvinum -> l 3 drives: D d2 State: up /dev/ad6s1a A: 0/152626 MB (0%) D d1 State: up /dev/ad4s1a A: 0/152626 MB (0%) D d0 State: up /dev/ad2s1a A: 0/152626 MB (0%) 1 volume: V music State: up Plexes: 1 Size: 298 GB 1 plex: P music.p0 R5 State: up Subdisks: 3 Size: 298 GB 3 subdisks: S music.p0.s0 State: up D: d0 Size: 149 GB S music.p0.s1 State: up D: d1 Size: 149 GB S music.p0.s2 State: up D: d2 Size: 149 GB Code:
# mount /dev/gvinum/music /music mount: /dev/gvinum/music : Invalid argument Code:
# ls -ltr /dev/gvinum/music crw-r----- 1 root operator 0, 88 May 24 11:45 /dev/gvinum/music Code:
# fsck -n -t ufs /dev/gvinum/music ** /dev/gvinum/music (NO WRITE) Cannot find file system superblock ioctl (GCINFO): Inappropriate ioctl for device fsck_ufs: /dev/gvinum/music: can't read disk label Code:
# file - < /dev/gvinum/music /dev/stdin: data I'd appreciate any help. Cheers, Matt. Last edited by vermaden; 26th May 2010 at 07:52 AM. Reason: Use [ code ] tags. |
