In that case, we'd certainly be interested in getting the
/opt/linstor-server/logs/ErrorReport-5B770066-000001.log file.
Looks like a satellite attempted to work with some data of a resource
that it had declared deleted before.

For recovery, disconnecting/reconnecting the Satellite (or just
restarting it) should suffice. It should normally also retry the
resource deletion afterwards.

I noticed the resource is in the "Primary" role. It might still be in
use, and in that case, LINSTOR can not successfully delete the resource,
because the layers below LINSTOR do not support that.

Thanks for the report, cheers
