As far as I know the UUID in mdadm.conf is the Device UUID for md0 which is used in /etc/fstab to mount the drive. The UUID reported by mdadm --examine is the UUID of the RAID Partition which must be the same for all Members of a raid.
Could you please attach a copy of /etc/mdadm/mdadm.conf the output of sudo mdadm --query --detail /dev/md0 the output of sudo mdadm --examine for every member of the raid the output of cat /proc/mdstat Could you please describe your issues? -- Wrong RAID UUID on PATA RAID5 partitions after Feisty Upgrade https://bugs.launchpad.net/bugs/107080 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
