The setup is 4 1TB drives running RAID10. I was using the Gnome Disk Utility to verify the integrity of the array (which is a 500MB mirrored md0 and the rest a R10 md1). I believe one of the drives is bad but prior to the system going offline it showed that 2 drives were detached from the array but healthy. A reboot results in a panic complaining that not enough mirrors are available. Is there a method to mount this array from a live CD so I can export the VM images. I have backups of the important ones but I'd lose 18 hours of data and a new PBX VM that was just finished but not backed up yet. I've been reading and testing various suggestions from the web but until I get this unit back up all phones and E-Mail are down, which leads to a slight panic, which makes it difficult to read and understand :) The backup server is at another location so I'm trying to recover first. Any direction would be appreciated. Thanks, Jacob
