I have too many strays that seem to be causing disk full errors when
deleting man files (hundreds of thousands) the number here is down from
over 400k. I have been trying to up the number of processes to do this,
but it is not happening:
ceph tell mds.ceph-0 injectargs --mds-max-purge-ops-per-pg 2
2017-03-03 15:44:00.606548 7fd96400a700 0 client.225772 ms_handle_reset
on 172.16.31.1:6800/55710
2017-03-03 15:44:00.618556 7fd96400a700 0 client.225776 ms_handle_reset
on 172.16.31.1:6800/55710
mds_max_purge_ops_per_pg = '2'
ceph tell mds.ceph-0 injectargs --mds-max-purge-ops 16384
2017-03-03 15:45:27.256132 7ff6d900c700 0 client.225808 ms_handle_reset
on 172.16.31.1:6800/55710
2017-03-03 15:45:27.268302 7ff6d900c700 0 client.225812 ms_handle_reset
on 172.16.31.1:6800/55710
mds_max_purge_ops = '16384'
I do have a backfill running as I also have a new node that is almost
done. Any ideas as to what is going on here?
