I think that quirks were entirely related to creation/deletion of lvm volumes (backend of drbd ones). In one case, restore operation resulted in correct creation of new drbd resource, but on one node the assignment was pending, with "drbdmanage resume-all" didn't fixing it. I resolved with a "drbdadm down <vm-resource>" on the problematic node, removing (lvremove) the backend lvm volume, and reissuing a "drbdmanage resume-all" that recreated it correctly. Now I can delete the test vm and restore it without any problem. So, my advice in case of problems creating/deleting/restoring vms is to check that creation/deletion of backend lvm volumes is correctly performed as expected. rob _______________________________________________ drbd-user mailing list drbd-user@lists.linbit.com http://lists.linbit.com/mailman/listinfo/drbd-user
