1. I delete my old array md0
2. Then I create a new one as md1
3. The new md1 is not ok and shows removed, faulty and spare devices.
5. I tried this serveral times now, but i always get the same issue.
I am at my wits end and would very much appreciate your advice. Thank
you in advance.
This is what I did:
/dev/ mdadm --stop md0
mdadm: stopped md0
/dev/ mdadm --remove md0
/dev/ mdadm --detail md0
mdadm: md device md0 does not appear to be active.
/dev/ mdadm --zero-superblock /dev/sdd1
/dev/ mdadm --zero-superblock /dev/sdc1
mdadm: Unrecognised md component device - /dev/sdc1
/dev/ mdadm --zero-superblock /dev/sdb1
/dev/ mdadm --create --verbose /dev/md1 --chunk=64 --level=5
--raid-devices=2 /dev/sdd1 /dev/sdb1
mdadm: layout defaults to left-symmetric
mdadm: size set to 1953511936K
mdadm: array /dev/md1 started.
/dev/ mdadm --detail md1
