[linux-lvm] Using existing lvm2 volumes with clvm?

[Steve Wray]

Hi there,
I have an existing setup of volume groups which I'd like to share on a 
cluster using iscsi and clvm.

Is this possible?

The volume groups and logical volumes have already been created and the 
physical volumes are Linux software RAID arrays. The LV's are populated 
with filesystems which I'd like to make available across the network 
(for XEN virtualisation and migration).

If I export these physical volumes with iscsi and use them as physical 
volumes in clvm on other machines, can this be expected to work or will 
it exterminate the existing volume groups on those physical volumes?
:)

Thanks!
