I would say this is a problem of ntfs mount.. I found another way to do this, 
so that’s that.


Thanks for noticing.

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
