Yes. Upgrade :-) This looks like the bug that was fixed in SLES10-SP2 by an update on May 9th this year. The relevant bugzilla is https://bugzilla.novell.com/show_bug.cgi?id=368704 There is a patch linked in there. If you cannot find an upgrade, you could just compile your own mdadm from the latest source. NeilBrown
