I've experienced a similar issue before. I had a raid 6 array that I'd built with some disks, then, after it appeared to be built okay, I grew it onto two more disks. Alas, the first set of devices in the array were the partitions, the other two were, accidentally, the drives. And somehow, the last two drives AND partitions contained superblocks.
Oh, and I don't know why you have two lines in your config for md0, with different UUIDs. You should really only have one. So one of those ARRAY lines should go. And you should query and then erase the superblock on the drive (NOT the partition) (assuming there's one duplicated on both). I'd caught my two partitions appearing sometimes just after boot, but mdadm would quickly get all confused and eject them. I'd have to manually kill of mdadm, partprobe to get the partitions back and then assemble by directly specifying devices (partitions) not UUIDs, until I realised the real problem with the duplicate superblocks. -- RAID5 partitions disappear after initial reboot https://bugs.launchpad.net/bugs/332235 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
