The alternative ugh is to switch to ubuntu. I suspect if we do go ahead it will come down to one of our guys going down there to do the hands on. I'm still looking for good examples of exactly how to do the actual recovery. I assume I can just do gmirror remove gm0 /dev/ad4 to eliminate the bad disk. However, will the system still reboot from the disk on /dev/ad6 or should the good disk be swapped into the /dev/ad4 position. I don't know enough about sata booting, but I suppose it can be configured through our serial console. If the system does boot then the other disk can be inserted with gmirror insert gm0 /dev/ad6, but I am not sure whether any partitioning/formatting etc etc is required, Dru Lavigne was my guide when we installed this stuff, but this is the first time it's failed and she doesn't mention the repair process. -- Robin Becker
