Has anyone used Drbd with LVM snapshots? I have lvm on top of drbd so that I can try snapshotting the contents of the main storage on the primary node while it has it mounted. drbd0 - > partition1 (large) drbd1 -> partition2 (small) one vg on top of drbd0 and drbd1. I know about not putting any fs across two devices due to the lack of guarantee on consistency, so I restricted the lv to use only the drbd0 device completely and left the smaller drbd1 device for snapshots. I made the snapshot successfully (read only) but it seems as though I cannot mount the snapshot to read from it. I guess this is due to some drbd magic locking or something under the hood to change the block headers to not work for data safety. I really want to both replicate (which is working well) and also to take snapshots of the main area some how. Can anyone tell me if what I am trying to do is completely off or if this can be done in another way? -h -- Hari Sekhon Always open to interesting opportunities http://www.linkedin.com/in/harisekhon
