Kernel panic during boot with software RAID1
I am using 3 SATA disks in a software RAID1 array running on FC6.
When I remove one of the disks and connect it to a different computer (with different motherboard....etc.) the computer starts to boot but then complains about the file system and panics. Here are the last few lines of console output during boot: Does anyone have a clue what the problem is?

By the sound of things the problem is in the /etc/fstab file. The system is trying to mount the file systems listed in fstab and they are associated with the device names for the drive when it is part of the RAID array. See if you can boot to a shell and then make a copy of the file and edit it changing the mount devices to /dev/sda or what ever device the controller is now using. The actual device name is listed as the system detects devices and if it is a sata drive off of a regular controller it is probably /dev/sda or /dev/hda.

Thanks for the reply. It turns out that my problem was partially fixed by changing the
BIOS setting on the target computer to disable PATA and enable SATA mode ONLY. This means that the CD ( and other IDE ) stuff does not work- not what I want. I think I may repost to the hardware forum for additional help. Pete |
