Ok, I did the following:
# mdadm --create /dev/md0 --level=5 --raid-devices=3 /dev/hdg1 /dev/hdd1
/dev/hdc1
mdadm: array /dev/md0 started.
# mdadm /dev/md0 -a /dev/hde1
mdadm: hot added /dev/hde1
# mount /data
mount: wrong fs type, bad option, bad superblock on /dev/md0,
or too many mounted file systems
# cat /proc/mdstat
Personalities : [raid5]
read_ahead 1024 sectors
md0 : active raid5 hde1[4] hdc1[3] hdd1[1] hdg1[0]
240121472 blocks level 5, 64k chunk, algorithm 2 [3/2] [UU_]

If I read your email correctly, I wasn't expecting this. But I'm also
inexperienced enough to not really know what to expect. All I know is
that I now have movement where, before, I had none.
So is this good or bad? Is my data gone forever (I gave up on it a while
back, so if it's gone, it's gone)?
Thanks again, Luca. You rock!
