Hello,

I am facing unability to create new volumes or enlarge old ones on a
three node DRBD9 cluster.

DRBD9 packages are latest from proxmox-4 linbit repo.

DRBD9 storage uses ThinLV volumes as backend, and replicaton size is
three for all volumes.

# drbdmanage list-free-space -m 3

vm-122-disk-1,,0,8388608,7011,131,
vm-123-disk-1,,0,5242880,7012,135,

The sum of single volume sizes is 1093664768; so 583831552 bytes are
missing.

I have tried issuing

drbdmanage update-pool

without success.

Any suggestion?

Thanks,
rob
