I'm not sure why this keeps going wrong, but I do know I made a mistake
when initially reconstructing the array. What I did was the following:
# mdadm /dev/md1 --add /dev/hde
Releazing that I didn't want to add the complete drive (/dev/hde) but only
one of its partitions (/dev/hde1) I then did (while it was still
rebuilding):
# mdadm /dev/md1 --fail /dev/hde
# mdadm /dev/md1 --remove /dev/hde
I'm not 100% sure but it *may* have rebuilt the superblock.
do:
mdadm --examine /dev/hde
mdadm --examine /dev/hde1
If hde has a superblock then that could be picked up before the hde1 one.
(ah, read more of your email and you were on the right tracks :) )
To fix this do:
mdadm --zero-superblock /dev/hde
Once all this is done you may want to run a check on the array.
There's probably other stuff going on with partition table caches too - blockdev
-rereadpt may make a difference... but I suspect the --zero-superblock will just
fix it all on the next boot.
