[Linux-cluster] Antwort: Re: clvmd does not create vgs

[brem belguebli]

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
