1) I used apt-get to procure and install Ceph excluding the standalone client on Lucid Lynx. I obtained built the client using instructions on the Ceph wiki and it worked fine after I reverted certain commits. However, mkcephfs (from: $ /usr/sbin/mkcephfs -c /etc/ceph/ceph.conf --allhosts -v) has been breaking: 2011-03-28 13:23:23.596948 b77b16d0 OSD::mkfs: couldn't mount FileStore: error -95 2011-03-28 13:23:23.597008 b77b16d0 ** ERROR: error creating empty object store in /data/osd0: error 95: Operation not supported failed: '/usr/bin/cosd -c /etc/ceph/ceph.conf --monmap /tmp/mkcephfs.DZdhzxPY5k/monmap.24380 -i 0 --mkfs --osd-data /data/osd0' Additionally, I checked and /data/osd0 does exist... 2) I want to be able to tune Ceph's configuration parameters (located in config.cc within the Ceph source) and see how each configuration change impacts Ceph's performance. However, I am not certain how changes in the ceph source code will be reflected in the standalone-client in terms of Ceph's performance. Is there a suggested way I could work to accomplish changing parameters in the source in order to have the file system impacted by these changes? I'd appreciate your help!
