Then you haven't cloned the volume, but it is the same, would be my guess.

Thanks for the response. Is it normal for when I change it on one node, the other node reflects the same UUID? node1: tunefs.ocfs2 -q -Q "BS=%5B\nUUID=%U\n" /dev/sdb1 BS= 4096 UUID=ea0778bd-bdaa-44af-8fbf-cb4a5d85e79f node2: tunefs.ocfs2 -q -Q "BS=%5B\nUUID=%U\n" /dev/sdb1 BS= 4096 UUID=ea0778bd-bdaa-44af-8fbf-cb4a5d85e79f On Wed, Nov 24, 2010 at 3:00 PM, Ulf Zimmermann <u...@openlane.com<mailto:u...@openlane.com>> wrote: After the clone, you want to probably run tunefs.ocfs2 -U to reset the UUID. This is one of the steps we do when cloning volumes for database refreshes.

I setup a host with an ocfs partition on a san and then cloned that host to another and renamed. Both machines mount their ocfs partitions but give the following errors.

I unmount the drives and remounted and they were the same again. Thanks for any guidance, cat /etc/ocfs2/cluster.conf node: ip_port = 7777 ip_address = 10.x.x.248 number = 0 name = smes01 cluster = ocfs2 node: ip_port = 7777 ip_address = 10.x.x.249 number = 1 name = smes02 cluster = ocfs2 cluster: node_count = 2 name = ocfs2 cluster.conf same on both hosts.
