Shortly after upgrading from bobtail to cuttlefish I tried increasing
the number of monitors in my small test cluster from 1 to 3, but I
believe I messed something up in the process. At first I thought the
conversion to leveldb failed, but after digging into it a bit I
believe this explains it:
# ceph --admin-daemon /run/ceph/ceph-mon.a.asok mon_status
{ "name": "a",
"rank": 0,
"state": "probing",
"election_epoch": 0,
"quorum": [],
"outside_quorum": [
"a"],
"extra_probe_peers": [],
"monmap": { "epoch": 2,
"fsid": "6917a033-3439-4fd7-88db-46c9e1df0d6e",
"modified": "2013-05-22 21:45:39.239582",
"created": "2012-12-28 11:35:06.671375",
"mons": [
{ "rank": 0,
"name": "a",
"addr": "172.24.88.50:6789\/0"},
{ "rank": 1,
"name": "mon.b",
"addr": "172.24.88.53:6789\/0"}]}}
At this point I would like to remove the one named "mon.b" since it is
named wrong (should be just "b"), and I would like to get back to a
working state before attempting to expand to 3 monitors again.
I've tried using monmaptool and ceph-mon to inject it, but that hasn't
worked for me yet:
# monmaptool --print monmap.dat
monmaptool: monmap file monmap.dat
epoch 1
fsid 6917a033-3439-4fd7-88db-46c9e1df0d6e
last_changed 2012-12-28 11:35:06.671375
created 2012-12-28 11:35:06.671375
0: 172.24.88.50:6789/0 mon.a
# ceph-mon -i a --inject-monmap monmap.dat
[3506]: (33) Numerical argument out of domain
Is there something I'm missing?
Thanks,
Bryan
