Thank you, Nate. We actually had a 3Ware raid cage on site and installed it to house the two drives.
Pulled the source drive to test fail over and this time the OS didn't immediately crash. But after, roughly, two minutes the machine became unresponsive except for the mouse. Interestingly, it appeared that what ever was cached still worked while "cat /proc/mdstat" didn't show a drive failure. Any ideas on how to make Linux RAID 1 failover work with IDE drives. Many thanks in advance. James D.

Most hardware does not. The most common hot swap configuration is using 80pin SCA SCSI drives using a hotswap backplane. Recently I configured such a system, and yanked a drive while the system was running and the system didn't skip a beat. Plugged it back in, ran a few commands and the array resynched. I most DEFINATELY would NOT reccomend using those $20 IDE disk cages, some of which advertise "hot swap". If your using IDE disks there are some hot swap capable cages, the only one I can think of at the moment comes from 3ware. Not sure on the cost. system freeze is a typical response for the hardware having a non recoverable error. nate -- redhat-list mailing list unsubscribe mailto:[EMAIL PROTECTED] https://listman.redhat.com/mailman/listinfo/redhat-list -- redhat-list mailing list unsubscribe mailto:[EMAIL PROTECTED] https://listman.redhat.com/mailman/listinfo/redhat-list
