Description
I have a bunch of misdirected requests from a recent kernel client to a hammer cluster, triggered by osd rm:
2017-02-27 15:37:56.976845 osd.190 10.115.1.133:6808/3914 97 : cluster [WRN] client.9450549 10.115.1.35:0/1493770383 misdirected client.9450549.1:1379645861 pg 2.ec640804 to osd.190 in e241865, client e241865 pg 2.804 features 288863570635346
e241864 -> e241865 incremental:
{ "epoch": 241865, "fsid": "9e3e9015-f626-4a44-83f7-0a939ef7ec02", "modified": "2017-02-27 11:07:56.497658", "new_pool_max": -1, "new_flags": -1, "new_max_osd": -1, "new_pools": [], "new_pool_names": [], "old_pools": [], "new_up_osds": [], "new_weight": [], "osd_state_xor": [ { "osd": 204, "state_xor": [ "autoout", "exists" ] }, [], [], [], [], [], [], [], [], [ { "osd": 204, "uuid": "00000000-0000-0000-0000-000000000000" } ], {}, [] ]
On master:

but (with osdmaptool patched to accept and apply incrementals):
$ bin/osdmaptool --test-map-pg 2.ec640804 /tmp/map-241864.bin /tmp/inc-241865.bin bin/osdmaptool: osdmap file '/tmp/map-241864.bin' bin/osdmaptool: incremental file '/tmp/inc-241865.bin' parsed '2.ec640804' -> 2.ec640804 2.ec640804 raw ([190,1], p190) up ([190,1], p190) acting ([190,1], p190)
which is where the misdirected request was sent.
On hammer:
$ ./osdmaptool --test-map-pg 2.ec640804 /tmp/map-241864.bin ./osdmaptool: osdmap file '/tmp/map-241864.bin' parsed '2.ec640804' -> 2.ec640804 2.ec640804 raw ([197,201,1], p197) up ([197,201,1], p197) acting ([197,201,1], p197) $ ./osdmaptool --test-map-pg 2.ec640804 /tmp/map-241865.bin ./osdmaptool: osdmap file '/tmp/map-241865.bin' parsed '2.ec640804' -> 2.ec640804 2.ec640804 raw ([197,201,1], p197) up ([197,201,1], p197) acting ([197,201,1], p197)
and (same osdmaptool patch):
$ ./osdmaptool --test-map-pg 2.ec640804 /tmp/map-241864.bin /tmp/inc-241865.bin ./osdmaptool: osdmap file '/tmp/map-241864.bin' ./osdmaptool: incremental file '/tmp/inc-241865.bin' parsed '2.ec640804' -> 2.ec640804 2.ec640804 raw ([197,201,1], p197) up ([197,201,1], p197) acting ([197,201,1], p197)
