Hi Heinz. I'm awfully sorry for directly asking for help to you, but I'm cranking my head on an issue you might have an immediate answer for. By default, dm-mpath-selector seems to always does round-robin between all paths. Is there a way to do simple failover instead or round-robin, ie. define a preferred path and keep the other one as a spare? It seems possible with md multipath, but then there is no way to create an DM RAID0 over these md devices. Hope you can help, -Frank. _______________________________________________ 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/
