In the WebGUI's "logical device information" section, that particular drive is listed as a "hard disk" whereas the other 3 are clearly spelled out as a "RAID 5" array. When I shut the machine down, I will check the BIOS itself to see if it specifically states "JBOD." Thanks for the pointer. Regardless, I will be backing it up before I attempt to plug it into a new RAID controller. >> I'm curious to know if the array could be migrated just as easily, or if >> I should listen to my instinct and count on bumping into >> incompatibilities due to proprietary implementations. > > I can absolutely guarantee you that you will lose access to all of your > data once you plug those 3 disks into another controller. > > You need to back up all of your data from the RAID-5 array using > something like rsync, cpdup, or dump, move the disks over to the > non-RAID controller, format them (in whatever fashion you want), > and then restore the backup. Exactly what I planned to do, but figured I'd ask anyhow. ;-) Thank you for responding. -- Anthony Chavez http://hexadecagram.org/ mailto:[EMAIL PROTECTED] xmpp:[EMAIL PROTECTED] _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
