I think that everyone lese lives in a far more ordered universe than i do. My "problem" - no, wait - "challenge" is that i have zero control over the origin of incoming media on USB and eSATA. Could be any brand of USB stick sold under the sun or HDDs formatted FAT32, NTFS, ext2/3. The only constants are things i directly control (sysdisk, RAID) - everything else is a crap-shoot. Everyone else can use labels. I don't know about you but it "feels" like mounting a RAID array, possibly with an active mySQL database on it under udev is kind of disaster-prone. I would much rather mount via fstab. - csawyer -----Original Message----- From: centos-bounces at centos.org [mailto:centos-bounces at centos.org] On Behalf Of Brunner, Brian T.

UUID is out of the question where I have 3 drives (main and two backup) with "wear leveling" wherein ANY of the drives, put in /dev/sda's position, is the boot drive, the identical backup on /dev/sdb will get backed-up-to on a daily basis, and on a weekly basis the drive in /dev/sdb moves to /dev/sda's connector (becoming the boot drive), '/dev/sda' goes off-site, and the third moves to /dev/sdb's position (and gets backed-up-onto promptly.
