You also want fencing if you're using clustered LVM to protect the LVM metadata, but I don't know if it's strictly *required* or not, since you're statically assigning VGs to specific nodes. Note that if you just assign static LUNs to each node and manage those LUNs from the SAN management interface, you don't even need lvm2-cluster or CMAN. For example, you can present only certain LUNs to certain computers. > We do realize that we are ignoring many of the key features of the > cluster setup where we could define these LVs and their file systems as > resourced as well as the services using them and have cman, rgmanager, > etc help build a more robust and polished setup. -- Lon -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
