Hi all

in preparation of a migration from Sles 10 SP1/OES2 to Sles 10 SP2/OES SP1 we did install all patches available for Sles 10 SP1 (also a Kernel update).

After several days we rebooted the server and after rebooting, GRUB said "no valid partition". GRUB didn't recognize our Linux RAID-1 /dev/md0.

So in the end we saw no other posibillity than reinstall the entire System with Sles 10 SP2 (took us all night).

Has anyone seen a behavior like this?
