Copy-on-read/write will now use an empty snapshot context to deep-copy the object through all existing snapshots. With the deep-flatten feature enabled, the flatten operation will now disconnect a child image from its parent even if it has existing snapshots. Signed-off-by: Jason Dillaman <dillaman@redhat.com> |

Build Prerequisites
debian-based
The list of debian packages dependencies can be installed with:
./install-deps.sh
Note: libsnappy-dev and libleveldb-dev are not available upstream for Debian Squeeze. Backports for Ceph can be found at ceph.com/debian-leveldb.
rpm-based
The list of RPM packages dependencies can be installed with:
./install-deps.sh
Building Ceph
Developers, please refer to the Developer Guide for more information, otherwise, you can build the server daemons, and FUSE client, by executing the following:
./autogen.sh
./configure
make
(Note that the FUSE client will only be built if libfuse is present.)
Dependencies
The configure script will complain about any missing dependencies as it goes. You can also refer to debian/control or ceph.spec.in for the package build dependencies on those platforms. In many cases, dependencies can be avoided with --with-foo or --without-bar switches. For example,
./configure --with-nss # use libnss instead of libcrypto++
./configure --without-radosgw # do not build radosgw
./configure --without-tcmalloc # avoid google-perftools dependency
Building packages
You can build packages for Debian or Debian-derived (e.g., Ubuntu) systems with
sudo apt-get install dpkg-dev
dpkg-checkbuilddeps # make sure we have all dependencies
dpkg-buildpackage
For RPM-based systems (Red Hat, SUSE, etc.),
rpmbuild
Building the Documentation
Prerequisites
The list of package dependencies for building the documentation can be found in doc_deps.deb.txt:
sudo apt-get install `cat doc_deps.deb.txt`
Building the Documentation
To build the documentation, ensure that you are in the top-level `/ceph directory, and execute the build script. For example:
admin/build-doc
