Hi Gian,<div><br></div><div>You're right, if you use a Cluster LVM [1] then you will be able to use migration with an empty tm_mv.sh (as you point out, same idea as the tm_mv.sh in the TM_NFS drivers).</div><div><br></div>

Limitations confirmed :(.<br>
<br>
Anyway, I would work with a clustered volume group, that is every node<br>
sees the same VG, and that is very close to NFS case where everybody<br>
see the same thing.<br>
<br>
Is it safe then, to assume that tm_mv it's a no op ?<br>
<br>
I would like avoid using a distributed fs and keep my VMs on a logical<br>
volume, and since all nodes share the volume group, migration and<br>
stopping should be a no-op... Or am I wrong ?<br>
