It does. A tricky part is how to simulate a drive death. Pulling a live plug on IDE is problematic. (I remember recently seeing mention in the kernel 2.5 discussions about implementing IDE hotplug. I am pretty sure 2.4 does not think it supports hotplug of IDE.) Because of how PCs boot, booting with a drive missing can make for problems. I still don't know if there is a way to make a drive bootable no matter where the BIOS thinks it is. I know raid 1 works because I had it do so. On Red Hat 7.0 I had bootable software raid 1 running on two different controllers. (I shared one controller with a CD-ROM.) One day while I was buring a CD (I figure that had something to do with it) one of my drives died. Judging from the log files it was in the middle of a DMA. And I never knew anything happened, the machine kept running, my CD was burned. It was only the next moring when I got an automatic e-mail telling me that /porc/mdstatus had changed. My machine wasn't bootable at that point without some futzing, but it kept running. I finally got a new drive, stuck it in, and it seems happy still. -kb -- redhat-list mailing list unsubscribe mailto:[EMAIL PROTECTED] https://listman.redhat.com/mailman/listinfo/redhat-list
