Hi,

Since my email server falled down because the error. I have to reply 
this way.

I added more logs:


   int r = store->omap_get_values(coll, pgmeta_oid, keys, &values);
   if (r == 0) {
     assert(values.size() == 2); <<<<------

      0> 2017-12-03 13:39:29.497091 7f467ba0b8c0 -1 osd/PG.cc: In 
function 'static int PG::peek_map_epoch(ObjectStore*, spg_t, epoch_t*, 
ceph::bufferlist*)' thread 7f467ba0b8c0 time 2017-12-03 13:39:29.495311
osd/PG.cc: 3025: FAILED assert(values.size() == 2)

And this is what happens:

What I see is that pg omap_get_values 9.b9 is causing the troubles, so I 
suppose that deleting this pg at all can make it run a little more or 
forever.


What do you think?
