hi everybody!
i found out, that the superblock of my raid5 array says it's built out
of 7 disks, but i created it with only 6 disk. the mdadm call used to
create the array was:
mdadm --create /dev/md6 -c 64 -l raid5 -p ls -n 6 --spare-disks=0 \
/dev/hde1 /dev/hdg1 /dev/hdi1 /dev/hdk1 /dev/hdm1 /dev/hdo1
i grep'ed through my .bash_history and that was the only line showing
mdadm --create.
i'm using mdadm version 0.7.2, i think that is pretty old. i will
upgrade to a more recent version and recreate the array.
still i would like to know if i encountered a bug or if thats some other
problem. this mdadm version is the one from debian woody (stable).
output of mdadm --detail /dev/md6

it seems there are no errors but i don't want to encounter a drive
failure and beeing stuck with a 2 drive failure (i know there are ways
to get a 2 drive failure array back up and working)
thanks in advance
