Hi, My MDS is very slow, and it logs stuff like this: 2014-11-07 23:38:41.154939 7f8180a31700 0 log_channel(default) log [WRN] : 2 slow requests, 1 included below; oldest blocked for > 187.777061 secs 2014-11-07 23:38:41.154956 7f8180a31700 0 log_channel(default) log [WRN] : slow request 121.322570 seconds old, received at 2014-11-07 23:36:39.832336: client_request(client.7071:115 getattr pAsLsXsFs #1000002bdbe 2014-11-07 23:36:39.000000) currently failed to rdlock, waiting Any idea what that rdlock is and what might cause it to fail? This is on Giant by the way. Thanks, Erik. _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
