I have encountered a problem that i managed to fix but am more
interested to know if that ever happened to anyone here. A server was
showing signs of weirdness and slowness when i decided to check its
soft RAID (md0 & md1, namely /usr & /var). After having rebooted from
a Debian Netinst CD, i fsck'd the 2 volumes and there were a lot of
inode errors. So it went happily and fixed all of these.
On reboot, no more RAID could be seen, it kept saying that the
superblock was wrong. I ended up booting back from the Netinst CD and
recreate the volumes, then changed the UUID number in mdadm.conf and
the server is now happy again.
So my question : has anyone seen that and more importantly, does
anyone know how that could have happened ?
The server is vanilla Debian Sarge with two SATA drives using Soft
RAID, kernel is also Debian vanilla k7.
