Thanks - that's exactly what I've done and it's rebuilding as we speak. I did toy with recreating the array (to get sda1 back in place as a non-spare) but wasn't sure if re-writing the RAID superblock would affect the resizing that was in progress? > Then add sda1 back in and it will recover and the array will be optimal. Will do. Having to do a sync twice is a bit painful, but at least I've got the array back :) Once again, thanks - the assistance is much appreciated. -mj -- Michael-John Turner mj@mjturner.net <> http://mjturner.net/
