So is clvmd running fine on both nodes? If its not, your not going to be able to do anything with the shared storage. After you have verified its running, do a vgscan. If you get any errors, you have to fix those first before you can move ahead to worrying about the lv issues.
I am far from a cluster expert. Im actually having my own issues right now, but I am just passing on some info that I have learned along the way. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: Tuesday, October 07, 2008 2:10 PM To: linux-cluster@redhat.com Subject: [Linux-cluster] RE: Can't create LV in 2-node cluster Hi Mark, This is just an experimental cluster for now, not production, so 2-nodes is sufficient (as long as it doesn't significantly alter the setup, which I don;t think it does). I have two multi-pathed iSCSI targets for storage, one each on two separate boxes. I have got this going previously on a slightly different set-up elsewhere, but this is my next effort that incorporates easy shutdown/startup of the storage and cluster. Except I can't get the LV up and running...

Also, 2 node clusters are highly discouraged from my experience and recommendations of others. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: Monday, October 06, 2008 10:28 AM To: linux-cluster@redhat.com Subject: [Linux-cluster] Can't create LV in 2-node cluster Hi everyone, I have created a 2-node cluster and (after a little difficulty) created a clustered volume group visible on both nodes. However, I can't create a logical volume on either node. I get the following error: Error locking on node <other node>: Error backing up metadata, can't find VG for group #global Aborting. Failed to activate new LV to wipe the start of it. I have locking_type = 3 and locking_library = liblvm2clusterlock.so. The metadata areas and sequence nos are the same using vgdisplay on both nodes. Can anyone help me create LVs? I am happy to provide any extra info needed.
