Hi :)
I've had a drive die recently, and took the opportunity to upgrade my
aging Debian sarge box to etch. Once the new OS was running and I had
finished beating booting from /dev/md0 with a blunt instrument, I turned
my attention to the data raid-sets... there's only one I can't sort out,
and of course.. it's the biggest one :)
eddie:~# cat /proc/mdstat
Personalities : [raid1] [raid6] [raid5] [raid4]
md3 : active raid5 hda4[1] hdg4[2]
349702144 blocks level 5, 1024k chunk, algorithm 0 [3/2] [_UU]
eddie:~# mdadm --add /dev/md3 /dev/hde5
mdadm: add new device failed for /dev/hde5 as 3: Invalid argument
hda and hdg are 200G drives. hde is the new one at 250G. I have
configured the partition sizes + types (0xFD) identically, but the
partition number is different on hde because I wanted to put extra stuff
in the 'spare' 50G.. so the set should be using hda4, hdg4, hde5.

As you can see, only hde thinks it's a spare, when I want it to replace
that 'removed' in all cases. What can I do?
Debian etch, so kernel 2.6.18 and mdadm 2.5.6.
Cheers,
Gavin.
