Posted by Ben Heavner on 05/31/02 07:48 PM
Has anyone done an oACS or postgres install on a linux box with the Linux Volume Manager? LVM seems to be the linux equivalent of Solstice Disc Suite forSolaris, and I was thinking of playing with it a bit. Has anyone tried it before me?

LVM is at www.sistina.com/products_lvm.htm

I've run Linux boxes with LVM for around 9 months now, without any hiccups.

It's been in the Kernel since 2.3.x, so, most of the bugs seem to have been shaken out (and, I've never seen any).

I've run Oracle ontop of LVM, without any hassles, so I can't see any difficulties running oACS/Postgres ontop.

It's _extremely_ useful, I gave a talk to the Scottish Linux User Group last month, on enterprise Linux servres, the slides from that are available at http://www.tech-linux.org/enterprise/.

Yes, go for LVM, although you won't survive without it, once you've used it :)

Hi Ben,

I use LVM on both my office machine (XFS + LVM) and home (ReiserFS +
LVM).  Its been really great and useful at times.  Since sometimes I
needed to extend my logical volumes I can do it on the fly without a
restart.

Here are the things that I learned

- try to put /boot in non LVM partition its easier that way.  My
office box is full LVM so I had to use initrd to boot it up.

- Avoid spaning multiple disks.  Since removing a part of the span
will surely kill the partition.  If needed then be aware of how your
partitions are spanned.

I have run LVM on my office machine for over a year now, no probs
with Oracle, Postgres, etc.  I have not implemented LVM on our
production server since I am an ocean away.  Although I will do it
if given the chance since I got lucky in a remote kernel compile and
reshuffling of the partitions a few moons ago.  Our test and
development server
will soon have LVM on their next upgrade.
