There's no packages for 2.6.26 in the repos anymore, so I built myself some kernel packages from the 2.6.26-5.17 sources, which is listed as the most recent pre-2.6.27 source package in launchpad.
Rebooted, and my array is happily syncing, so it definitely seems to be a problem with 2.6.27. -- mdadm RAID10 arrays cannot be rebuilt, will not use available spare drives https://bugs.launchpad.net/bugs/285156 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
