Ceph is a distributed object, block, and file storage platform
15d85af4ce
We specifically want to use this during recovery to avoid loading the obc or ssc for a previous version of the object and populating the watchers. We know we won't have any existing obc here because it is missing (old or dne). For the snapset context, we provide it explicitly when we recover the head or snapset object (which we always do first). For clones, we re-use the existing get_snapset_context(), which will either have the ssc open or can load it from the head/snapset object. Signed-off-by: Sage Weil <sage@newdream.net> |

Ceph - a scalable distributed storage system ----------------------------------------- Please see http://ceph.newdream.net/ for current info. ---- To build the server daemons, and FUSE client, $ ./autogen.sh $ ./configure $ make (Note that the FUSE client will only be built if libfuse is present.) ---- A quick summary of binaries that will be built in src/ daemons: ceph-mon -- monitor daemon. handles cluster state and configuration information. ceph-osd -- storage daemon. stores objects on a given block device. ceph-mds -- metadata daemon. handles file system namespace. ceph-fuse -- fuse client. tools: ceph -- send management commands to the monitor cluster. rados -- interact with the object store rbd -- manipulate rados block device images monmaptool -- create/edit mon map osdmaptool -- create/edit osd map crushtool -- create/edit crush map scripts: mkcephfs -- cluster mkfs tool init-ceph -- init.d start/stop script
