I have a similar problem, now running the 2.6.27 kernel. Ian Olivers nice workaround solves it, but there is a spooky md0 array that i can not get rid of.
>mdadm --examine --brief --scan --config=partitions ARRAY /dev/md0 level=raid0 num-devices=2 UUID=7d97e292: ... /* /dev/sd[c-d] - won't go away */ ARRAY /dev/md1 level=raid0 num-devices=4 UUID=84d9862b: ... /* /dev/sd[e-h]1 - working fine */ ARRAY /dev/md0 level=raid0 num-devices=2 UUID=279762b4: ... /* /dev/sd[c-d]1 - now loop[1-2] */ The history is: /dev/sdc & /dev/sdd was first setup. Then removed and replaced by /dev/sdc1 & /dev/sdd1. That worked fine for a long time until the next reboot. Then the first array reappeared and could not be removed. And it became a horrible mess. Many Thanks for the workaround! - but I hope for a cleaner solution. -- mdadm cannot assemble array as cannot open drive with O_EXCL https://bugs.launchpad.net/bugs/27037 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
