Hmm.... Interesting now. I have no admin socket opened around.
root@p01:/var/run/ceph# ls /var/run/ceph -al total 0 drwxr-xr-x 2 root root 40 Sep 9 07:47 . drwxr-xr-x 17 root root 600 Sep 11 21:23 .. root@p01:/var/run/ceph# lsof | grep radosgw.asok root@p01:/var/run/ceph# I review the on-line doc for radosgw : http://ceph.com/docs/next/radosgw/config-ref/ There's no configuration for rgw admin socket tho. root@s01:~# ceph --admin-daemon /var/run/ceph/ceph-osd.2.asok config show | grep rgw_thread "rgw_thread_pool_size": "100", 1. I found that the OSD config information includes rgw_thread_pool_size , is this what you mentioned ? 2. Why that the value is on OSD? 3. Where is the value of rgw_thread_pool_size that OSDs referenced from ? +Hugo Kuo+ (+886) 935004793 2013/9/12 Yehuda Sadeh <[email protected]> > On Wed, Sep 11, 2013 at 9:34 PM, Kuo Hugo <[email protected]> wrote: > > Hi Yehuda, > > > > Here's my ceph.conf > > > > root@p01:/tmp# cat /etc/ceph/ceph.conf > > [global] > > fsid = 6e05675c-f545-4d88-9784-ea56ceda750e > > mon_initial_members = s01, s02, s03 > > mon_host = 192.168.2.61,192.168.2.62,192.168.2.63 > > auth_supported = cephx > > osd_journal_size = 1024 > > filestore_xattr_use_omap = true > > > > [client.radosgw.gateway] > > host = p01 > > keyring = /etc/ceph/keyring.radosgw.gateway > > rgw_socket_path = /tmp/radosgw.sock > > log_file = /var/log/ceph/radosgw.log > > rgw_thread_pool_size = 200 > > > > Depends on my conf, the /tmp/radosgw.sock was created while starting > radosgw > > service. > > So that I tried to show up config by : > > > > root@p01:/tmp# ceph --admin-daemon /tmp/radosgw.sock config show > > read only got 0 bytes of 4 expected for response length; invalid command? > > > > Is it a bug or operation mistake ? > > You're connecting to the wrong socket.
