Dear ceph-devel
Cluster environment composed of three hosts,each host runs a monitor process and ten OSD processes
If one of the hosts in the cluster is restarted,we run 'rbd create……' command will block 120 seconds,but the normal is blocked for 20 seconds.
When a host is down, OSD status remains in the cluster is "UP".
Tracking function"osdmonitor::check_failure", the variable "osd_xinfo_t.laggy_interval" values is verylarge, and far more
than 20 seconds, but is normally 0.
So, the variable"osd_xinfo_t.laggy_interval" why does exist?
Looking forward to your reply,Thank you!

you can add debug_rados or debug_ms to rbd create command to see what happened during 120s
