I'm also having this problem. It tries to stop my "root" raid, which of course is impossible whilst it's in use.
A developer on irc said they need to disable the stop call in preinst. and to check how they did it for version 2.5 in Debian. Would have been nice too if we got a newer mdadm for edgy, rather than a version from April this year. Especially since the edgy kernel has new features some of which work better with a newer mdadm. -- Upgrading mdadm package is impossible - can't upgrade while raid arrays active https://launchpad.net/bugs/60623 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
