I cannot replicate this issue. After deploying a monitor I have these permissions: sudo ls -alh /etc/ceph total 16K drwxr-xr-x 2 root root 4.0K Jan 22 18:40 . drwxr-xr-x 81 root root 4.0K Jan 22 18:39 .. -rw-r--r-- 1 root root 188 Jan 22 18:40 ceph.conf -rw-r--r-- 1 root root 92 Dec 20 22:01 rbdmap That means anyone can read: vagrant@precise64:~$ cat /etc/ceph/ceph.conf [global] fsid = cde681f7-fd8b-4d9b-8a73-3edce4a14116 mon_initial_members = node2 mon_host = 192.168.111.101 auth_supported = cephx osd_journal_size = 1024 filestore_xattr_use_omap = true > > > > The time stamp of the latest change to the ceph.conf file coincides with > when the ceph-deploy command above was run. > > > > I am running the latest version of ceph-deploy (1.3.4-0) on the Emperor > version of Ceph. > > > > I did check the ceph tracker for similar situations, but have not come > across anything so would appreciate some feedback on this. > > > > Thanks > > Alistair > > > > _______________________________________________ > > This message is for information purposes only, it is not a recommendation, > advice, offer or solicitation to buy or sell a product or service nor an > official confirmation of any transaction.
