Colin Patrick McCabe b46f847cf9 osd: mark_obj_as_lost: don't assume we have obj
In PG::mark_obj_as_lost, we have to mark a missing object as lost. We
should not assume that we have an old version of the missing object in
the ObjectStore. If the object doesn't exist in the object store, we
have to create it so that recovery can function correctly.

Ceph - a scalable distributed file system
-----------------------------------------

Please see http://ceph.newdream.net/ for current info.

----

To build the server daemons, and FUSE client,

$ ./autogen.sh
$ ./configure

$ make
 or
$ cd src
$ 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:
 cmon -- monitor daemon.  handles cluster state and configuration
         information.
 cosd -- storage daemon.  stores objects on a given block device.
 cmds -- metadata daemon.  handles file system namespace.
 ceph -- send management commands to the monitor cluster.

userland clients:
 cfuse -- fuse client.
 csyn -- synthetic workload generator client.

tools:
 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
