Hello Gandalf, Yes, if you have essentially high amount of commited data in the cluster and/or large number of PG(tens of thousands). If you have a room to experiment with this transition from scratch you may want to play with numbers in the OSD` queues since they causing deadlock-like behaviour on operations like increasing PG count or large pool deletion. If cluster has no I/O at all at the moment, such behaviour is not expected definitely. > _______________________________________________ > ceph-users mailing list > ceph-users@xxxxxxxxxxxxxx > http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com > _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
