Richard Jones' Log: Argh, more RAID problems :(

So now my RAID has decided to do something completely new: not work whenever I reboot.

When I boot up there's a message in my console saying that the superblock on /dev/sda4 (one of the two disks) doesn't match and that it's giving up.

This means that every time I boot up I have to edit the mdadm.conf file to remove /dev/sda4, run "mdadm -A /dev/md0" to have it create the array again, re-add /dev/sda4 to the config file and run "mdadm --manage /dev/md0 --add /dev/sda4". Then wait as it rebuilds the array (usually takes about 15 minutes). Then I can again mount /home and use my computer.

I have been unable to find anything about this on the 'net either, which makes me sad. I wish I knew why /dev/sda4 was getting out of sync...
