Unmount the filesystem, and run "vgexport" for the volume group.
Great.
Then take the volume offline via sysfs
You mean cchccwdev -d /dev/.... ?
sysfs manpage refers to /proc/filesystems which lists used file systems.
, and detach it from the guest (This assumes you're on the 2.6 kernel. With
2.4 it's a little more complicated).
on 2.6. Good to go!
Repeat the process in reverse on the other system, doing a vgimport on the
other side.
Cool.
I'm reasonably sure I've done this successfully.
It's much easier to set up an NFS share though, and leave the volume attached
to one guest.
Agreed, NFS would be helpful, but when you have to do repairs in single
user mode, it is good to mount the LVM in the sick guest sometimes and
do the repair, although most likely I will mount the sick volume on a
good guest. You got me thinking.
Thanks a bunch.

Subject: [LINUX-390] Is it possible to move an LVM from guest
to guest?
I want to set up an LVM that I can move from guest to guest. I have a
3390-09 volume that I want to use for this.
Why? It makes it easy to re-do file systems, at least for now.
I have LVM running on a couple of guests but I dont know if it is
possible to move this 'utility' LVM from guest to guest
easily *without*
any outage to the guests.
Thanks
