Neil,
First off, thanks for all your hard work on this software, it's really
a great thing to have.
But I've got some interesting issues here. Though not urgent. As
I've said in other messages, I've got a pair of 120gb HDs mirrored.
I'm using MD across partitions, /dev/hde1 and /dev/hdg1. Works
nicely.
But I see that I have an old superblock sitting around on /dev/hde
(notice, no partition here!) which I'd like to clean up.
# mdadm -E /dev/hde
/dev/hde:

Here's the correct ones:

I can't seem to zero it out:
# mdadm --misc --zero-superblock /dev/hde
mdadm: Couldn't open /dev/hde for write - not zeroing
Should I just ignore this, or should I break off /dev/hde from the
array and scrub the disk and then re-add it back in?
Also, can I upgrade my superblock to the latest version with out any
problems?
Thanks,
John
