Yes, ext3 reduces/eliminates fsck time on a reboot. The thing to keep in mind is that the value of LVM is in being able to add/remove disk volumes from a volume group without having to move/rebuild the whole file system. If you break out all your file systems that don't have to be in the root file system and put them on LVM, you are left with very, very little space being used, and it should not change very often at all. Putting the root file system on LVM introduces unnecessary complexity for no real gain. See the note from Peter Abresch about the gymnastics he had to go through to correct a problem with an LVM volume group. (Which, by the way, he wrote up for me and I'm going to upload to the web site soon.) Not something I want to have to deal with to get my system up to the point where I can connect to it remotely.

I forgot to mention in my original question that /boot wouldn't be in LVM, it'd be an ordinary partition. Thank you for pointing out the fsck time consideration. Doesn't having ext3 fs reduce the fsck time? My motivation in considering LVM is to get a general solution to my Linux dasd constraints that I can use on all my Linux guests. My Linux guests start out as clones with about 4GB of disk; a default install of SLES 8. ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
