I am about to begin a long needed rebuild of some servers and will be moving some drives around. One machine runs software RAID-1 on RH 7.3 with two identical 20gb drives. 3 partitions mirrored, /boot, / and swap. I would like to avoid having to take down all three servers for the ???? days it will take to rebuild them so can start the process if I can "steal" one of the mirrored drives on this machine. Is it possible to simply remove the second, mirrored drive and make some changes somewhere, fstab? and keep the system up while I use the removed drive? Here are the contents of my raidtab and fstab if that helps.

raidtab contents:

raiddev /dev/md0
raid-level 1
nr-raid-disks 2
chunk-size 64k
persistent-superblock 1
nr-spare-disks 0
device /dev/hda2
