Description
Writing large amount of data to EC RBD pool via NBD causes down OSDs, PGs and drop in traffic due to unhealthy cluster. OSDs themself are running, disks seem to be idle. In logs "heartbeat_map reset_timeout 'OSD::osd_op_tp thread 0x7f05d4c90700' had timed out after 60" (I increased it from 15 during testing) and slow requests can be observed.
Setting bluestore_throttle_bytes to 0 resolves issue.
Attaching gdb thread backtrace of one of OSDs.
