Will this work with 3.6? Is there any reason clustered lvm is required over<br>

I didn't try yet 3.6, but as seen in release notes for beta version, there are no changes in transfer manager drivers part, so it should work (but please test before using in production).<br>
<br>
For normal LVM with shared disks (SAN), there I have no experience. I suspect, that in this case probably "mv" script could be improved, by not copying from one node to another in some cases (and/or not creating the copy in file for STOP).<br>

but it's been unstable and I've lost data with high i/o.<br>

Hi,<br>
<br>
Because Debian 6.0 Xen doesn't support tap:aio: and because LVM disks are<br>
faster, I wrote modified transfer manager driver for opennebula 3.4.x, that<br>
use LVM volumes on local disks in virtualization hosts.<br>
<br>
There are 3 kinds:<br>
<br>
*) lvm2 - works with shared or not shared filesystem datastore (for system<br>
datastore there is parameter in lvm.conf to tell shared or not it is).<br>
<br>
*) lvm2ssh - the same, but removed code to detect that datastore is shared.<br>
<br>
*) lvm2shared - the same, but with only assumption, than datastore is<br>
shared.<br>
<br></div>
URL of all them is at <a href="http://mif.vu.lt/~rolnas/one/**one34/tm/" target="_blank">http://mif.vu.lt/~rolnas/one/*<u></u>*one34/tm/</a><<a href="http://mif.vu.lt/~rolnas/one/one34/tm/" target="_blank">http://mif.vu.lt/~<u></u>rolnas/one/one34/tm/</a>><div class="im">

P.S. This driver was in almost working condition in opennebula 3.2, but<br>
was lost in opennebula 3.4. lvm driver in opennebula 3.4.1 is not for<br>
system datastore and is different by design.<br></div>
