The cluster claims nothing, and shows HEALTH_OK still.
What I did is just vim a file storing on cephfs, and then it hung there.
And I got a process with 'D' stat.
By the way, the whole mount directory is still in use and with no error.
So there are no pending mds requests, mon seems to be ok, too.
But the osd requests seems to be stuck. Are you sure the ceph user used
for the mount point is allowed to write to the cephfs data pools? Are
you using additional EC data pools?

Burkhard
