Hi, I have a root raid1 partition on /dev/sda1 & /dev/sdb1 (swap on /dev/sda2 & /dev/sdb2). The server boots directly from the raid partition. Now /dev/sda1 and /dev/sda2 have both failed and been removed from the array and I am getting ready to replace the disk tonight. What is the best way to proceed to minimize downtime? My concern is that if I power down and replace /dev/sda the machine won't be able to reboot without a rescue CD (lilo.conf has root=/dev/md0 and boot=/dev/md0) or will it? When the bios (Dell Poweredge 1500) will try /dev/sda's mbr and fail, will it then automatically try /dev/sdb? Or should I swap /dev/sdb on the scsi ribbon to have it take the first place and thus become /dev/sda or will this just confuse the kernel raid driver? (the letter on scsi drives is dependent on their place on the ribbon cable, isn't it?) Alternatively I was thinking of booting with a rescue CD (after replacing /dev/sda) with the "root=/dev/md0", creating my partitions, running lilo and rebooting into production for final reconstruction. Would that be the safest bet?
