Problems with mdadm array superblock


I am trying to set up a raid 5 array with the mdadm utility. I created the array once with the command

mdadm -v -C /dev/md0 --raid-devices=3 --level=5 /dev/sd[cde]1

This array appears to work. I put an ext3 filesystem on it and mounted it and can mount it but when I use

mdadm --examine /dev/md0

it says superblock can not be read.


i also have an entry in my /proc/mdstat for md_d0 which i have tried to remove with --remove but i cant.

I tried to test a rebuild on the array as well but it says it can't read the superblock wen I run

mdadm --incremental --rebuild /dev/md0

I removed another drive and tried to add it back and it says it can't get the array info for /dev/md0

mdadm --incremental --rebuild /dev/md0
mdadm: no recognisable superblock on /dev/md0.
