Well, 4.1 is the latest and therefore the easiest to debug, assuming
this is a kernel client problem.
What is the output of /sys/kernel/debug/ceph/*/* when this happens? We
need to know whether it's making a very slow progress or just stuck, so
capture that output with something like watch(1). On the userspace
side crank up the log level - say, debug ms = 1 for osds and mons.
Unmap, map, reproduce and attach the above, along with full a dmesg.
Thanks,
Ilya
