I have a server which stores several LVM-2 logical volumes.
As this system is pretty loaded, I'd like to move some of the logical

as described in the LVM HOWTO (where one basically adds/replaces disks
in one machine).
My common sense tells me that I should:
1. Unmount/not use the logical volumes on the source server
2. Make volumes of the same size on the target server
3. Copy it somehow over network
I'm not sure of 2 (make volumes of exactly the same size)
check your PE size, otherwise does what it says on the tin.
Hmm, how? I just want to move some (not all) logical volumes.
I guess fdisk is a good idea?
# fdisk -l /dev/LVM2/ocsi1
Disk /dev/LVM2/ocsi1: 3221 MB, 3221225472 bytes
3221225472 / 1024 = 3145728
lvcreate -L3145728k -n ocsi1 LVM2
Hmm, hopefully, it's the right size?
and 3 (how to
copy it all over network, if possible, using SSH only).
netcat and dd over forwarded port
Thanks for the idea.
