Hi Having previously had problems during startup with "creating keys" (otherwise a working setup) one one node when using mkcephfs, i have given ceph-deploy a try and get stuck on what feels like the same step. Ceph version is 0.61.7 and OS is centos 6.4.
Steps i have done is:
#ceph-deploy new cloud-{0,1,2}-fast
#ceph-deploy --overwrite-conf mon create cloud-{0,1,2}-fast
Ceph-mon starts ok on all nodes and ceph-create-keys seems to be stuck.
cloud-1-fast: root 6580 1 0 11:45 ? 00:00:00 /usr/bin/ceph-mon
-i cloud-1 --pid-file /var/run/ceph/mon.cloud-1.pid -c /etc/ceph/ceph.conf
cloud-1-fast: root 6601 1 0 11:45 ? 00:00:00 /usr/bin/python
/usr/sbin/ceph-create-keys -i cloud-1
cloud-2-fast: root 18724 1 0 11:45 ? 00:00:00 /usr/bin/ceph-mon
-i cloud-2 --pid-file /var/run/ceph/mon.cloud-2.pid -c /etc/ceph/ceph.conf
cloud-2-fast: root 18747 1 0 11:45 ? 00:00:00 /usr/bin/python
/usr/sbin/ceph-create-keys -i cloud-2
cloud-0-fast: root 19629 8546 0 11:44 pts/0 00:00:00 su - ceph
cloud-0-fast: ceph 19630 19629 0 11:44 pts/0 00:00:00 -bash
cloud-0-fast: root 19853 1 0 11:45 ? 00:00:00 /usr/bin/ceph-mon
-i cloud-0 --pid-file /var/run/ceph/mon.cloud-0.pid -c /etc/ceph/ceph.conf
cloud-0-fast: root 19872 1 0 11:45 ? 00:00:00 /usr/bin/python
/usr/sbin/ceph-create-keys -i cloud-0
cloud-0-fast: ceph 20282 19630 0 11:46 pts/0 00:00:00 grep ceph
I have the /var/log/ceph/ceph-mon.cloud-0.log with debug turned on at
http://pastebin.com/DivE95mK
And the output from a strace of the ceph-create-keys from one of the nodes at
http://pastebin.com/JQak151Z
Worth mentioning is that each server has 2 interfaces cloud-* ("normal
interface") and cloud-*-fast (10gE that i want to use), hostname resolves to
cloud-*.
The small ceph.conf file created so far
[global]
debug_ms = 1
filestore_xattr_use_omap = true
debug_monc = 20
mon_host = 10.12.1.160,10.12.1.161,10.12.1.162
osd_journal_size = 1024
debug_mon = 20
mon_initial_members = cloud-0-fast, cloud-1-fast, cloud-2-fast
auth_supported = cephx
fsid = 90578caa-3c63-4183-96c7-176467a98ddb
