mdadm won 't start RAID5 array 2005-10-21 - By Jos Vos
Back
Hi,
When trying to re-assemble a RAID5 array of a disk cabinet with 8
disks (RAID5, 6 + 1 redundant + 1 spare) after a system crash,
using "mdadm -v --assemble /dev/md4 /dev/sda[m-t]1", I get:
mdadm: looking for devices for /dev/md4
mdadm: /dev/sdam1 is identified as a member of /dev/md4, slot 7.
mdadm: /dev/sdan1 is identified as a member of /dev/md4, slot 5.
mdadm: /dev/sdao1 is identified as a member of /dev/md4, slot 2.
mdadm: /dev/sdap1 is identified as a member of /dev/md4, slot 3.
mdadm: /dev/sdaq1 is identified as a member of /dev/md4, slot 4.
mdadm: /dev/sdar1 is identified as a member of /dev/md4, slot 0.
mdadm: /dev/sdas1 is identified as a member of /dev/md4, slot 6.
mdadm: /dev/sdat1 is identified as a member of /dev/md4, slot 1.
mdadm: added /dev/sdat1 to /dev/md4 as 1
mdadm: added /dev/sdao1 to /dev/md4 as 2
mdadm: added /dev/sdap1 to /dev/md4 as 3
mdadm: added /dev/sdaq1 to /dev/md4 as 4
mdadm: added /dev/sdan1 to /dev/md4 as 5
mdadm: added /dev/sdas1 to /dev/md4 as 6
mdadm: added /dev/sdam1 to /dev/md4 as 7
mdadm: added /dev/sdar1 to /dev/md4 as 0
mdadm: failed to RUN_ARRAY /dev/md4: Invalid argument
Also with --force it doesn't work. Doing "mdadm -E /dev/sda..." also
looks good for the disks involved, the only problem seems to be that
the array won't start.
Any ideas?
