I have built two RedHat 8.0 machines, both using soft-raid to mirror one 250GB disk onto the other identical 250GB disk inside the case.
During the install, I created the RAID partitions, and assigned them to actual partitions, and now I have "/dev/md0" up to "/dev/md7".
However, each time I boot and each time I shut down, I get the following message:
No spare disk to reconstruct array! -- running in degraded mode.
What exactly does this mean? Both drives are visible from the BIOS, and the jumpers are set to Cable Select (not Master and Slave).
Despite the above error message, the machine boots fine, shuts down fine, and runs fine.
However, if I unplug the master hard drive, it will not boot from the secondary, even if I plug it into the primary socket on the IDE cable.
I have even tried inserting a third 250GB hard drive on the secondary IDE channel to see if that would become the spare disk it needs to reconstruct the array, but that didn't work either.
Does anyone know what I'm doing wrong here? Should the disks be physically set to master and slave? Do I need to do something else to the RH8.0 config to make it work? I'm really confused...
Thanks in advance to anyone who can help
