I This is exactly why it is STRONGLY suggested you split your storage tier from your compute tier. The lowest friction method would be a pair that hold the disks (or access a common disk set) and export it as NFS. The compute nodes can speed things up with CacheFS for their local running VMs assuming you shepherd the live-migration process. If the VMs all want to have a shared filesystem for a running app and the app can't be written to work safely with NFS (why not?) then you can run corosync and friends +GFS2 at that level. _______________________________________________ linux-lvm mailing list linux-lvm@redhat.com https://www.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
