[DRBD-user] FAILED in e_end_resync_block

[Nick Potemkin]

Hello!

I have 5-nodes installation (4 nodes with one disk on each and one diskless
node).
Ubuntu 18.04 4.15.0-91-generic
DRBD: version: 9.0.22-1 (api:2/proto:86-116
Linstor 1.5.0

In any full resync of resource (for example after creation) i have strange
errors

[Wed Apr  8 14:16:16 2020] drbd one-vm-103-disk-2/0 drbd1027 csshv-94:
Began resync as SyncTarget (will sync 20975192 KB [5243798 bits set]).
