Hi, All!
I am trying to setup ceph from scratch, without dedicated drive, with one mon
and one osd.
After all, I see following output of ceph osd tree:
# id weight type name up/down reweight
-1 1 root default
-2 1 host host1
0 1 osd.0 down 0
ceph -w:
cluster e90dfd37-98d1-45bb-a847-8590a5ed8e71
health HEALTH_WARN 192 pgs stuck inactive; 192 pgs stuck unclean
monmap e1: 1 mons at {host1=172.17.0.4:6789/0}, election epoch 1, quorum 0
host1
osdmap e5: 1 osds: 0 up, 0 in
pgmap v6: 192 pgs, 3 pools, 0 bytes data, 0 objects
0 kB used, 0 kB / 0 kB avail
192 creating
2014-02-16 13:27:30.095938 mon.0 [INF] osdmap e5: 1 osds: 0 up, 0 in
What can be wrong?
I see working daemons, and nothing bad in log files.
////////////////////////////////////
How to reproduce:
I have cloned and compiled sources on debian/jessie:
git clone --recursive -b v0.75 https://github.com/ceph/ceph.git
cd /ceph/ && ./autogen.sh && ./configure && make && make install
Everything seems ok.
I have created ceph.conf:
[global]
fsid = e90dfd37-98d1-45bb-a847-8590a5ed8e71
mon initial members = host1
auth cluster required = cephx
auth service required = cephx

keyring = /data/ceph.client.admin.keyring
osd pool default size = 1
osd pool default min size = 1
osd pool default pg num = 333
osd pool default pgp num = 333
osd crush chooseleaf type = 0
osd journal size = 1000
filestore xattr use omap = true
;journal dio = false
;journal aio = false
mon addr = ceph.dkctl
mon host = ceph.dkctl
log file = /data/logs/ceph.log
[mon]
mon data = /data/mon0
keyring = /data/ceph.mon.keyring
log file = /data/logs/mon0.log
[osd.0]
osd host = host1
osd data = /data/osd0
osd journal = /data/osd0.journal
log file = /data/logs/osd0.log
keyring = /data/ceph.osd0.keyring

Daemons are alive, log files show evidences of some communications between mon
