  • Priority changed from Urgent to Normal

The mds was busy at opening inodes for reconnected client caps. There are two reason opening inodes took so long.

First, there were about 25000 client caps, probably caused by issue http://tracker.ceph.com/issues/21423.

Second, ms_inject_socket_failures was set to 2500. mds need to sent about 25000 getxattr requests to osd. Each time socket failed, messenger re-sent all these requests, but only about 1000 requests got sent successfully.
