Hi Jack, IIRC the main advantage of lvm is its expandability. Say you have a 2GB partition mounted as /home somewhere down the road this becomes too small and you really need 4GB. Without lvm you need to do the partition shuffle (yes it's like the masochism tango), with lvm the mount point can span multiple partitions/disks. It is one of the main reasons I'm looking forward to 6.3. Now if the local stores would realize what a great seasonal gift it would make and get it in stock. Tim

I never understood the purpose of lwm? Is it just supose to use all the disks in your server as ONE big disk and don't have to worry about anything, or is it for performance reasons? Sorry kinda new to anything other than standard 2.1 IDE hard drives in PC :)

But you will still need a file system, that can be dynamically resized. If you use ext2 on a logical volume, you can increase the volume itself, but you would still have to create a new file system to take use of the new space. This is where ReiserFS steps in. It does not only have journaling (so filesystem checks take seconds instead of hours), but it also includes an offline resizer (you have to unmount the filesystem before you can resize it). An online resizer (enlarging it on the fly) is under development. Unfortunately you can only enlarge it, not make it smaller, but that is the more popular case anyway :) Please note, that all this stuff is usable (I use ReiserFS on some of my partitions - it is _fast_!), but we do not recommend to use it in productive environments yet. A file system is a very critical part of an operating system :) For more info about this, see the web pages of ReiserFS and the LVM: http://devlinux.com/namesys/ http://linux.msede.com/lvm/ Bye, LenZ -- ------------------------------------------------------------------ Lenz Grimmer SuSE GmbH mailto:grimmer@suse.de Schanzaeckerstr. 10 http://www.suse.de/~grimmer 90443 Nuernberg, Germany -- To unsubscribe send e-mail to suse-linux-e-unsubscribe@suse.com For additional commands send e-mail to suse-linux-e-help@suse.com Also check the FAQ at http://www.suse.com/Support/Doku/FAQ/
Dear Lenz, These questions are still out there: 1. When installing SuSE for the first time, what are the steps required to implement LVM (via YAST1)? 2. Since SuSE included the LVM option with the current version of YAST1, would it be possible to get the help file pointing the way under the SuSE installation process? Your help would be most helpful!

How does this compare to a RAID0 or RAID-striped, which can be run on the root system from the moment of installation (I did this on two systems). Ie. what are the main differences?

Is does not compare at all. For as far as the layout of partitions is concerned, any RAID config should still be seen as one disk. Actually, in your fdisk display, it will show up as one disk.

Does that mean that I can set up a small 540 meg hd as /boot a resonable /swap then the balance as / then add a second 540 meg hd and use LVM to add the second hard drive to / Now that would be neat , as the install is allways very tight on just a / partion. Previosly I ended up using the whole firt drive for / and the second drive carved up for /boot , /opt and /swap . That helped a little , but not much. At least I was able to get a workable system out of it for a firewall and ip masq. I know , I know , I tried deleteing a buch of packages , but kept trashing my system and it wouldent boot , hence the odd mapping of the drives. Now can you use lvm at initial install , or is that only can be used afterward.

This is a little off the main thread, but Best Buy down in Sacramento must have had 10 boxes of 6.3 for $29.95 each. If you have one withing 50 mi, I'd try there.

My wife picked up SuSE 6.3 at CompUSA in Las Vegas. They had more boxes of SuSE on the shelf than RH and Caldera combined. John ----- Original Message ----- From: Gail Allinson <gailla@jps.net> Subject: RE: [SLE] SuSE LVM (local store addendum)
