In brief: seen similar problem. Solved adding "r|/dev/drbd.*|" to global_filter in lvm.conf
In detail: I've seen a similar issue as the one described by Greb: taking a snapshot (either from Proxmox web gui or from the command line with linstor) resulted in an error (Storage configuration exception). I've also noticed that, on all the satellite nodes: * lvdisplay command became unresponsive * could not interrupt the (unresponsive) lvdisplay with ctrl+c * dmesg repetedly reported an hung task (vgs) * drbdadmin status reported (for the snapshotted resource): vm-101-disk-1 role:Secondary suspended:user disk:UpToDate blocked:upper n01-pve role:Secondary peer-disk:UpToDate * drbdsetup resume-io <MINOR of the suspended resource> made lvdisplay responsive again and stopped the hung-task errors in dmesg I suspect vgs hung while scanning block devices, when meeting the io-suspended drbdXXXX resource. Adding "r|/dev/drbd.*|" to global_filter in lvm.conf seems to solve all the issues for me.
