Thanks. That was the page I had read earlier.

I've attached the full outputs to this mail and show just clips below.

# ceph health detail
OBJECT_UNFOUND 1/731529 unfound (0.000%)
    pg 6.2 has 1 unfound objects

There looks like one number that shouldn't be there...
# ceph pg 6.2 list_missing
{
    "offset": {
...
        "pool": -9223372036854775808,
        "namespace": ""
    },
...

# ceph -s
    osd: 6 osds: 6 up, 6 in; 10 remapped pgs

This shows under the pg query that something believes that osd "2" is
down, but all OSDs are up, as seen in the previous ceph -s command.
# ceph pg 6.2 query
    "recovery_state": [
        {
            "name": "Started/Primary/Active",
            "enter_time": "2017-09-12 10:33:11.193486",
            "might_have_unfound": [
                {
                    "osd": "0",
                    "status": "already probed"
                },
                {
                    "osd": "1",
                    "status": "already probed"
                },
                {
                    "osd": "2",
                    "status": "osd is down"
                },
                {
                    "osd": "4",
                    "status": "already probed"
                },
                {
                    "osd": "5",
                    "status": "already probed"
                }


If i go to a couple other OSDs, and run the same command,
the osd "2" is listed as "already probed". They are not in sync. I
double checked that all the OSDs were up on all 3 times I ran the
command.

Now. my question to debug this to figure out if I want to
"revert|delete", is what in the heck are these file(s)/object(s)
associated with the pg? I assume this might be in the MDS, but I'd
like to see a file name associated with this to make a further
determination of what I should do.  I don't have enough information at
this point to figure out how I should recover.
