Hi,

 

On node1, you created the pv /dev/drbd/by-res/repdata (pvcreate) and added it to VG storage_cluster  (vgcreate ....).

 

On node2, as long as the device /dev/drbd/by-res/repdata  is accessible, a simple vgscan would discover the newly created pv and vg.

 

If there was a locking issue, it would complain on node2 that it couldn't activate any LV from  storage_cluster.

 

Can you post the output of pvs on node2 ?

 

 

This is how it works for me
