Just make sure that both disks are bootable and have a boot sector and then both disks should work. Unplug one at a time to check. Most BIOS's boot from the "first" disk they find with a master boot record, having both bootable is not a problems

This part of software raid is tricky, I discovered. I was one day sitting at my basement server, burning a CD when one of my raid 1 died in the midst of a DMA. I never knew there was a problem until the next morning when I got an e-mail from a cron job I have telling me that /proc/mdstat had changed. I now trust that Linux software raid 1 can survive a disk dying without bringing down the machine. Note: I have my swap on a raid partition too. The trickier part is rebooting if hda dies and the bios/lilo don't understand how to boot from hdc. I have not figured this out yet. I suggest you do some testing. Boot off a CD and blow away the partition table on one of your disks and see if it will boot off the other. If it does, re-partition that disk again and add it to the array. Then do the same thing to the other disk. If either disk can boot and you can restore the other in both cases, then I think you are ready for prime time. -kb, the Kent who is behind on this score and still have some work to do. -- redhat-list mailing list unsubscribe mailto:redhat-list-request@;redhat.com?subject=unsubscribe https://listman.redhat.com/mailman/listinfo/redhat-list -- redhat-list mailing list unsubscribe mailto:redhat-list-request@;redhat.com?subject=unsubscribe https://listman.redhat.com/mailman/listinfo/redhat-list
