* Help to assemble raid5 - no superblock! @ 2012-04-04 11:15 Salatiel Filho 2012-04-04 11:47 ` NeilBrown 0 siblings, 1 reply; 4+ messages in thread From: Salatiel Filho @ 2012-04-04 11:15 UTC (permalink / raw) To: linux-raid I am having a big problem trying to assemble my raid. I can assemble just fine in the old machine (LINUX ARM) where i built the raid in the first place, but i am just unable to do in other machine (Linux mips). I have no mdadm.conf in both machines.

ARM is little-endian MIPS ?? is that bigendian? What does mdadm -E --metadata=0.swap /dev/sda2 report? If it is something useful, then try adding --update=byteorder to the "mdadm -A" command.

That should fix the checksum. The byte-order has already been fixed, so it doesn't need fixing again.
