It started with sda - sdz, then sdaa - sdaz, and finished out in the sdba - sdbz range. I was using LVM2 to organize them into several different volume groups.
While you can do the disk-by-id that Michael was talking about, I prefer to use the good-old-fashioned /dev/sda1 for a small boot partition, and everything else is arranged with lvm volumes; that gives me the ability to rearrange disk location, and device names I can remember (ie /dev/vgmyth/video). I was a firm believer in gparted back in the day, but after learning the wonders of lvm, I rarely ever use parted anymore. There are people that will try to convince you to skip LVM and use ZFS, but everyone I know that was using ZFS took off to the Great White North. ;-) Grazie, ;-Daniel Fussell /* PLUG: http://plug.org, #utah on irc.freenode.net Unsubscribe: http://plug.org/mailman/options/plug Don't fear the penguin. */
