I have an Ubuntu machine (10.04 but had the same problem in 8.04) with a bunch of drives that I use as a file server. 1 SATA that I boot off of. 2 IDE that in RAID1 and 2 SATA in RAID1. The problem is the drives that I have in RAID1 change device names on reboot.

This is a problem because the in my mdadm.conf a reference to /dev/sda1, for example, might not work the next time I reboot because /dev/sda1 could be a disk from another array.

Any help getting around this would be appreciated.
