I'm trying to assemble the array as much as possible, but I can't because it
complains about missing super blocks. Anyone got suggestions (/dev/sdb2 is
on the dead drive)
root@sysresccd /root %
mdadm --assemble /dev/md2 /dev/sda2 /dev/sdb2 /dev/sdc2 /dev/sdd2 /dev/sde2
mdadm: no RAID superblock on /dev/sdb2
mdadm: /dev/sdb2 has no superblock - assembly aborted
root@sysresccd /root %
mdadm --assemble /dev/md2 /dev/sda2 /dev/sdc2 /dev/sdd2 /dev/sde2
mdadm: cannot open device /dev/sde2: No such file or directory
mdadm: /dev/sde2 has no superblock - assembly aborted
root@sysresccd /root % mdadm --assemble /dev/md2 /dev/sda2 /dev/sdc2 /dev/sdd2
mdadm: /dev/md2 assembled from 2 drives - not enough to start the array.
root@sysresccd /root % mdadm --manage --run /dev/md2
mdadm: failed to run array /dev/md2: Input/output error
root@sysresccd /root % mdadm --detail /dev/md2
