Description

From list:

Hey folks,

I'm helping put together a new test/experimental cluster, and hit this today when bringing the cluster up for the first time (using mkcephfs).

After doing the normal "service ceph -a start", I noticed one OSD was down, and a lot of PGs were stuck creating. I tried restarting the down OSD, but it would come up. It always had this error:

-1> 2013-04-27 18:11:56.179804 b6fcd000  2 osd.1 0 boot
     0> 2013-04-27 18:11:56.402161 b6fcd000 -1 osd/PG.cc: In function 'static epoch_t PG::peek_map_epoch(ObjectStore*, coll_t, hobject_t&, ceph::bufferlist*)' thread b6fcd000 time 2013-04-27 18:11:56.399089
osd/PG.cc: 2556: FAILED assert(values.size() == 1)

 5: (__libc_start_main()+0x99) [0xb69bcf42]
 NOTE: a copy of the executable, or `objdump -rdS <executable>` is needed to interpret this.

I then did a full cluster restart, and now I have ten OSDs down -- each showing the same exception/failed assert.
