Sounds like a bad backplane, or HBA. > What's the best utility to back up the whole disk, allowing me to restore > to a drive (or array) of a different size?

What filesystem are you using? if it's ext4, then dump -0uaf would be the most efficient and reliable way to backup the entire filesystem. Unfortunately, since it includes your OS too... The restore procedure can be a pain. Because dump only backs up the filesystem. Not the partition tables or MBR etc. You should really be able to fix your system, which sounds like a hardware problem. _______________________________________________ Discuss mailing list [email protected] http://lists.blu.org/mailman/listinfo/discuss
