Ignore the kernel patching instructions! It's already included.
I'm running on this box. It's straight out of the box Redhat 8.0.
I've been prodded. I'll see if I can scribble up some simple instructions.
HOWEVER:
<WARNING>
You cannot ovelay it on a live system! It WILL erase all existing data on the drive(s). It can only be done on new drives, or at new installation time, when you can sacrifice the data on the disks.
</WARNING>
If you're installing new disk(s), or re-installing a system, and don't care about losing the existing data. go for it!

LVM is good stuff.
Unfortunately, it's only good stuff if you install it at the begining. It cannot be retroactivly installed. (that's the bad news).
If you're building a new system, you'll need to do some planning for your filesystems. The boot partition cannot be on an LVM. So you can end up with something like:
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/hda1 124427 19935 98068 17% /boot
/dev/datavg/rootlv 253871 139648 101116 59% /
/dev/datavg/usrlv 2064208 1876556 82796 96% /usr
/dev/datavg/varlv 507748 64738 416796 14% /var
/dev/datavg/tmplv 126931 4756 115622 4% /tmp
/dev/datavg/optlv 2064208 56692 1902660 3% /opt
/dev/datavg/srclv 1032088 198744 780916 21% /usr/src
/dev/datavg/locallv 2064208 47968 1911384 3% /usr/local
/dev/datavg/homelv 4128448 165852 3752884 5% /home
/dev/datavg/Datalv 25040764 252444 23516308 2% /Data
none 256592 0 256592 0% /dev/shm
Note that /boot is on /dev/hda1, not on the logical volume. The remainder of the box, is build on logical volumes.
Sistina has a lengthly discussion on LVM. It's really not as complex as it sounds. It just takes a little doing to get your head around it. It makes more sense (human sense) if you are dealing with multiple drives. It gets kinda fuzzy when you start speaking of "Volume Groups" in reference to a single drive. ;)
I don't think there is a HOW-TO out yet for it. Maybe someone needs to prod me with a sharp stick, and make me write one... (I suppose if I'm going to rant about it, the least I could do is write up a simple mini-HOW-TO on the subject..

Doug;
Thanks for adding that. I meant to put in a link to sistina, and didn't.
Yes, LVM is included with RH 8.0. In fact, you can set it up at install time.
I'm not sure that ext3 will expand "on the fly" though. I haven't tried. But ReiserFS, jfs, and xfs all will.

I'd also suggest looking into a filesystem that expands
fly, reiserFS, jfs (needs a patch), xfs, etc. I'd alsograb the latest
toolset for lvm from there as well.doesn't have lvm
I'm not sure on 8.0, but on 7.2 and 7.3, the RH kernel
in the kernel by defualt, IIRC

OK, cool. Thanks for the rant.
Now, how about a pointer to more information on LVM, like aHOWTO, whetherit's installed by default in 7.2/7.3/8.0, where to get it,etc. instead????John-----Original Message----- From: Tibbetts, Ric [mailto:[EMAIL PROTECTED]] Sent: Wednesday, January 29, 2003 12:56 PM To: [EMAIL PROTECTED] <mailto:[EMAIL PROTECTED]> Subject: Re: how to resize partition without losing data?

There's nothing bugs me worse than to see soemone answer a Linux
question with "I have this great Windows utility..".
LVM folks. Look it up, learn it, use it! IT's the answer to
situations
like this one.
Once set up, I can do fun things like:
enlarge a filesystem "on the fly" (no reboots required,no data loss).Add new filesystems "on the fly". No reboot required.
And more!
IT's part of Linux now. Stop depending on Windowssolutions. LVM hasbeen with unix for many years. IBM pioneered it a long time ago. It has since been adopted by nearly every other vendor under the sun. There's no need for the continued dependance on Windows based solutions. It's an insult to the Linux community to do so.
