I have not. I will look into that. Thanks for the tip.

Have you altered the following option in your lvm.conf to have a list of your VGs that can be activated?

Make sure you add any local VG required for your system to boot else your machine will fail to restart and you will only notice after a new kernel which creates a new initrd.

volume_list=[]

Are you using pacemaker?

I have a 2-node cluster, where each node is primary for one drbd volume and secondary for the other node’s drbd volume. Replication is A->B for drbd0 and A<-B for drbd1. I have a logical volume and filesystem on each drbd device. When I try to failover resources, the filesystem fails to mount because lvdisplay shows the logical volume is listed as “not available” on the target node. Is there some trick to getting LVM on DRBD to fail over properly?
