Hi,
I am newbie of ceph, now I am trying to deploy following
"http://ceph.com/docs/master/start/quick-ceph-deploy/";
ceph1, ceph2 and ceph3 exists according to the above tutorial. I got a
WARNING message when I exec ceph-deploy "mon create-initial".
2014-02-01 14:06:37,385 [ceph_deploy.gatherkeys][WARNING] Unable to find
/etc/ceph/ceph.client.admin.keyring on ['ceph1']
2014-02-01 14:06:37,516 [ceph_deploy.gatherkeys][WARNING] Unable to find
/var/lib/ceph/bootstrap-osd/ceph.keyring on ['ceph1']
2014-02-01 14:06:37,639 [ceph_deploy.gatherkeys][WARNING] Unable to find
/var/lib/ceph/bootstrap-mds/ceph.keyring on ['ceph1']
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.
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
