I had this issue on a RAID 10 with f2 layout with 3 disks. After upgrade from intrepid to jaunty (production) RAID(s) 1 were fine, but RAID 10 was inactive with only sdc(4) showing.
Fix was rather simple, only: $ sudo mdadm --stop /dev/md_d2 $ sudo mdadm --assemble --scan Result: /dev/md2: File exists mdadm: /dev/md/2 has been started with 3 drives. and then: $ sudo mount -a and array was back... -- Raid10 array not assembled at boot, all disks are marked as spare https://bugs.launchpad.net/bugs/316670 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
