Description

while testing http://tracker.ceph.com/issues/17275 I stumbled upon read request which was stuck for more than 2 days. ceph-fuse is 0.94.9 with patch from #17275. Cluster is 10.2.1.

Example of request:

        {
            "tid": 629298,
            "pg": "1.1ab4db54",
            "osd": 44,
            "object_id": "1000024655f.00025010",
            "object_locator": "@1",
            "target_object_id": "1000024655f.00025010",
            "target_object_locator": "@1",
            "paused": 0,
            "used_replica": 0,
            "precalc_pgid": 0,
            "last_sent": "2016-09-24 04:13:37.639395",
            "attempts": 1,
            "snapid": "head",
            "snap_context": "0=[]",
            "mtime": "0.000000",
            "osd_ops": [
                "read 131072~131072" 
            ]
        },

I am attaching some debug info, also:
client cache: ceph-post-file: cd539449-cca1-4b36-bf32-54f0353c0815
mds cache: ceph-post-file: 477d14b0-dcc9-4291-a7fd-fe654483b6b8

Now that ceph-fuse is not running so I am unable to collect additional debug from that, but if you would give me instructions I could collect that if issue will be founf again
