Hi, Tommi, Here is my ceph.conf. The "/var/log/ceph" folder is created by myself. Because the script in 0.37 didn't create it. Maybe the problem is I did not set correct permission to the folder. ; global [global] auth supported = cephx max open files = 131072 log file = /var/log/ceph/$name.log pid file = /var/run/ceph/$name.pid keyring = /etc/ceph/$name.keyring [mon] mon data = /srv/mon.$id [mon.a] host = ubuntu1104-64-5 mon addr = 172.16.33.5:6789 [mds] [mds.a] host = ubuntu1104-64-5 [osd] osd data = /srv/osd.$id osd journal = /srv/osd.$id.journal osd journal size = 1000 ; journal size, in megabytes [osd.0] host = ubuntu1104-64-6 btrfs devs = /dev/mapper/ubuntu1104--64--6-lvol0 [osd.1] host = ubuntu64-33-7 btrfs devs = /dev/mapper/ubuntu64--33--7-lvol0 [osd.2] host = ubuntu1104-64-5 btrfs devs = /dev/mapper/ubuntu1104--64--5-lvol0 regards, Eric/Pjack -----Original Message----- From: Tommi Virtanen [mailto:tommi.virtanen@xxxxxxxxxxxxx] Sent: Friday, November 04, 2011 1:51 AM To: Eric YH Chen/WHQ/Wistron Cc: gregory.farnum@xxxxxxxxxxxxx; ceph-devel@xxxxxxxxxxxxxxx Subject: Re: Cannot execute rados.py with sudoer On Wed, Nov 2, 2011 at 22:24, <Eric_YH_Chen@xxxxxxxxxxx> wrote: > The log is generated by ceph service at runtime. > > Even I change the permission, it would be overwritten by the service someday. Did you change ceph.conf and set one of the log options? The default config writes to /var/log only from the daemons, not from the libraries. Can you please share your configuration. As for needing to be able to read client.admin, that file is not changed by the ceph services starting, you can safely chown/chmod it. Alternatively, give the non-root user a new key, and authorize that with "ceph auth add". ��.n��������+%������w��{.n����z��u���ܨ}���Ơz�j:+v�����w����ޙ��&�)ߡ�a����z�ޗ���ݢj��w�f
