Ok, I've fixed it.. I'm replying to myself incase someone else with this problem comes across this post.
First, I thought, if I recreate the RAID-array EXACTLY as it was, the data on the old one shouldn't be erased, right? mkraid needed the /etc/raidtab, which I of cource no longer had, so I executed
lsraid -d /dev/hde3 -R > /etc/raidtab
to recreate it, then ran
to create a new array (on top of the old one). The -R option is to force mkraid to create the array, even though the partitions appears to contain data.
Now the array was up again, but it wouldn't mount
, so I ran
fsck.jfs -f /dev/md0
to fix it.
I don't know if it'll work for anyone else, but at least, if you're desperate enough, you could try it as a last resort before reformatting the whole thing...
My array is back
