try 'blkid' command to find out UUID use 'tune2fs' for ext3 filesystem, 'reiserfstune' for reiserfs filesystem, and 'xfs_admin' for xfs filesystem
my sample looks like: $ blkid /dev/sda1: UUID="546ea841-093b-42ea-964a-3c2e5ff3a2f3" TYPE="swap" /dev/sda2: UUID="df8eb64d-41d3-4fa6-88b2-5d8163fe4dbe" TYPE="reiserfs" /dev/sda3: UUID="546ea841-093b-42ea-964a-3c2e5ff3a203" TYPE="xfs" /dev/sdb1: UUID="546ea841-093b-42ea-964a-3c2e5ff3a2f3" TYPE="swap" /dev/sdb2: UUID="df8eb64d-41d3-4fa6-88b2-5d8163fe4dbe" TYPE="reiserfs" /dev/sdb3: UUID="546ea841-093b-42ea-964a-3c2e5ff3a203" TYPE="xfs" /dev/hdb1: UUID="7833498a-96aa-43fe-86e9-68647bbfe359" TYPE="swap" /dev/hdb2: UUID="66803B6F803B4539" LABEL="CONTENT" TYPE="ntfs" you can see e.g. there is dublicated UUIDs of /dev/sda2 and /dev/sdb2 (my root partition dmraid devices in raid1) i have just use: (e.g.) $sudo xfs_admin -U 546ea841-093b-42ea-964a-000000000000 /dev/sda1 $sudo reiserfstune -u df8eb64d-41d3-4fa6-88b2-000000000000 /dev/sda2 after that my UUID is not dublicate anymore and then dmraid -ay works!! my /dev/mapper/nvidia_blahblah appears fine! /dev/mapper/nvidia_blahblah2: UUID="df8eb64d-41d3-4fa6-88b2-000000000000" TYPE="reiserfs" /dev/mapper/nvidia_blahblah1: UUID="546ea841-093b-42ea-964a-3c2e5ff3a2f3" TYPE="swap" /dev/mapper/nvidia_blahblah3: UUID="546ea841-093b-42ea-964a-000000000000" TYPE="xfs" -- Cannot start from dmraid device anymore https://bugs.launchpad.net/bugs/141435 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
