Hello,

I'm currently running a NOSAN install with two hosts, and I noticed that my snapshots and machines are taking "thick" disk space.

running sr-list reveals that the iSCSI volume is running LVM.

Is there a way to run HA-lizards iscsi share as ext3 so I can take advantage of thin-provisioning?

The LVM layer is added to the storage by XenServer when the SR is introduced into the pool. Since we expose the storage via an iSCSI target, your options will be limited to what XenServer can do with iSCSI SRs. In this case, I don't think thin provisioning is supported. You may want to check the XenServer forums to be sure.
