My raid went suddently missing.. I googled some commands regarding a missing raid and I managed to start the raid again with mdadm --assemble /dev/md0. But..
mdadm: /dev/md0 has been started with 4 drives (out of 5).
My sdf drives wont start. mdadm: no RAID superblock on /dev/sdf
SMART says nothing is wrong with the drive. How can I get superblocks on again and what is it?
Thanks in advance.
