The pvcreate > alone is probably enough to damage it. What FS is on it now? Oops, I see now that it is already gfs2. If the other node is in the same cluster, it's just a matter of making sure there are enough journals. Assuming there is, you should be able to just connect the LUN to the node and mount it. I see no reason to do the LVM or mkfs.gfs2 steps. Always best to test of course. -- Digimer Papers and Projects: https://alteeve.ca/w/ What if the cure for cancer is trapped in the mind of a person without access to education? -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
