New pvc from snapshot got "destroyed" after a few seconds

[tobg]

Snapshots are working flawlessly. If we try to create pvc out of snapshots most of the time the new pvc gets destroyed after a few seconds. It starts syncing first and after a few seconds we see the following:

 digoc.tobg.services     ┊ pvc-35c1cb30-28e0-4307-ba4e-cf3bdd5d031f ┊ lvm-std-ha           ┊     0 ┊    1397 ┊ /dev/drbd1397 ┊            ┊ Unused ┊      Error ┊

linstor v l shows:
ERROR:

    The volume could not be found on the system.

We use pvc from snapshots temporarily as a possibility to export snapshots to s3 storage.
