Thanks Dean, I am setting up a Fedora 5 machine, which I configured to use RAID1 for all partions during the install and the resulting madadm.conf it generated is: DEVICE partitions MAILADDR root ARRAY /dev/md3 super-minor=3 ARRAY /dev/md1 super-minor=1 ARRAY /dev/md4 super-minor=4 ARRAY /dev/md0 super-minor=0 ARRAY /dev/md2 super-minor=2 To remove all doubt about what is assembled where, I though going to: DEVICE partitions MAILADDR root ARRAY /dev/md3 UUID=xyz etc. would be more secure. Is this correct thinking on my part?

UUID's
If I have specified an array in mdadm.conf using UUID's: ARRAY /dev/md0 UUID=3aaa0122:29827cfa:5331ad66:ca767371 and I replace a failed drive in the array, will the new drive be given the previous UUID, or do I need to upate the mdadm.conf entry?
