[Linux-cluster] how can I share a logical volume?

[John Ruemker]

When you say you want to share storage with the other 2 nodes, do you 
mean only one node is physically connected to the storage and exports it 
to the other 2?  Or do you mean that all three nodes are connected to 
the same storage and they share the device? 


If the former, gnbd is probably what you want.  If the latter, you 
should see the same devices (/dev/sdX) on each node.  If you do not, you 
have misconfigured your HBA or LUNs.  Once they all see the same 
devices, you should be able to start clvmd and all 3 will see the 
clustered volume group.
