Hi Alfredo,

Thanks for your reply!

I think I pasted all logs from ceph.log,  but anyway, I re-executed
"ceph-deploy mon create-initial again"
Does that make sense? It seems like stack strace are added...

Those seem bad enough. There is a ticket open for these type of
tracebacks that should be gone with the
up coming release of ceph-deploy.

Your monitor does seem like in a good state. Have you checked the
monitor logs to see if they are complaining
about something?

I would also raise the log level in ceph.conf for the monitors specifically to:

   debug mon = 10



Thanks for your reply.
I did "debug mon = 10", but I could not find any error logs in /var/log/ceph/ceph-mon.ceph1.log. So I tried to let ceph-create-keys generate logs to files, and inserted log by myself for debugging purpose. Then I found get_key() in ceph-create-keys complains like below. ( first line is inserted by me)
> INFO:ceph-create-keys: ceph --cluster=ceph --name=mon. --keyring=/var/lib/ceph/mon/ceph-ceph1/keyring auth get-or-create client.admin mon allow * osd allow * mds allow 
> INFO:ceph-create-keys:Talking to monitor...
> INFO:ceph-create-keys:Cannot get or create admin key, permission denied

So I tried,
> root@ceph1:~/my-cluster# chown -R ceph:ceph /var/lib/ceph/mon/
> root@ceph1:~/my-cluster# start ceph-all && stop ceph-all
> ceph-all start/running
> ceph-all stop/waiting

Then I re-tried:
> ceph@ceph1:~/my-cluster$ ceph-deploy --overwrite-conf mon create-initial
After that, I found some files are still owned b root. Is this a correct behavior? 
> root@ceph1:~/my-cluster# ls -l /var/lib/ceph/mon/ceph-ceph1/store.db
> total 1184

Also, looks like ceph-create-keys and ceph-mon are launched by root. Is this correct?

Hi,

I am newbie of ceph, now I am trying to deploy following

WARNING message when I exec ceph-deploy "mon create-initial".

Thinking about when those 3 keyrings should be created, I thins
"ceph-deploy mon create " is a right timing for keyring creation. I
checked my environment, and found
/etc/ceph/ceph.client.admin.keyring.14081.tmp. It looks like this file
is created by ceph-create-keys on executing stop ceph-all && start
ceph-all. but ceph-create-keys never finishes.

ceph-deploy tries to help here a lot with create-initial, and although
the warnings are useful,
they are only good depending on the context of the rest of the output.

When the whole process completes, does ceph-deploy say all mons are up
and running?

It would be better to paste the complete output of the call so we can
see the details.

When I execute ceph-create-keys manually, it continues to generate
below
log, looks like waiting reply...

2014-02-01 20:13:02.847737 7f55e81a4700  0 -- :/1001774 >>
192.168.11.8:6789/0 pipe(0x7f55e4024400 sd=3 :0 s=1 pgs=0 cs=0 l=1
c=0x7f55e4024660).fault

Since I found that mon listens 6789, so I strace mon, then mon also
waiting something...

root@ceph1:~/src/ceph-0.56.7# strace -p 1047
Process 1047 attached - interrupt to quit
futex(0x7f37c14839d0, FUTEX_WAIT, 1102, NULL

I have no idea what situation should be, any hints?

P.S. somebody give me an adivce to check below, but I dont see any from
here.
root@ceph1:~/my-cluster# ceph daemon mon.`hostname` mon_status
