I don't use LVM yet, but I found that using hard-coded /dev/sda?? or /dev/hda?? in /etc/fstab is not recommended. If LVM supports them, partition labels are the way to go. /dev/?da?? get screwed up if you create or destroy partitions. Whereas labels don't care about the actual device name in question. >From my etc/fstab file: ########################################################################## # device sda - PRIMARY MASTER - BOTTOM BAY 4 ########################################################################## LABEL=Fedora-12-root / ext3 defaults 1 1 #/dev/sda5 LABEL=home /home ext3 defaults 1 2 # dev/sda6 LABEL=other-docs /mnt/other-docs ext3 rw,noauto,noexec,user 0 0 # dev/sda7 LABEL=tmp /tmp ext3 defaults 1 2 HTH Keith Roberts ----------------------------------------------------------------- Websites: http://www.php-debuggers.net http://www.karsites.net http://www.raised-from-the-dead.org.uk All email addresses are challenge-response protected with TMDA [http://tmda.net] -----------------------------------------------------------------
