Hello, I have an old Dell Poweredge 2500 server running Fedora Core 3. The server had one of its power units failed, and (I think) as a result, the raid arrays got damaged: three of them stayed alive (though degraded), but one is not accessible. Unfortunately, the server only has a floppy drive which doesn't work now, and so I cannot get any files, command outputs directly off the box. I copy it all from the screen. The array I cannot access is md3. It has the shared libraries on it so many commands do not work. In particular, I cannot have remote access to the box. The output of mdadm -Es is (I am not copying the UUIDs) ARRAY /dev/md0 level=raid1 num-devices=2 devices=/dev/sdb2,/dev/sdc2 ARRAY /dev/md2 level=raid1 num-devices=2 devices=/dev/sda6,/dev/sdc3 ARRAY /dev/md3 level=raid5 num-devices=3 devices=/dev/sda3,/dev/sdb1,/dev/sdc1 ARRAY /dev/md1 level=raid1 num-devices=2 devices=/dev/sda1,/dev/sda2 Also md0 mounted at / md2 mounted at /var md1 mounted at /boot md3 should be mounted at /home # cat /proc/mdstat Personalities: raid1 raid5 md1: active raid1 sda2[1] sda1[0] 104320 blocks [2/2] [UU] md2: active raid1 sda6[0] 513984 blocks [2/1] [U_] md0: active raid1 sdc2[1] 1534080 blocks [2/1] [_U] unused devices: none # mdadm --detail /dev/md3 mdadm: md device /dev/md3 does not appear to be active At somebody's suggestion I tried mdadm --assemble --scan /dev/md0 and got /dev/sda has no superblock - assembly aborted Then tried mdadm --force --run /dev/md3 and got failed to run array /dev/md3: Invalid argument I finally tried # mdadm --assemble /dev/md3 /dev/sda3 /dev/sdb1 /dev/sdc1 mdadm: device 1 in /dev/md3 has wrong state superblock, but /dev/sdb1 seems ok Thanks for any help. I certainly would give remote access to a helping hand, but unfortunately the box cannot run sshd: the shared libraries are on the md3 array.
