Sage Weil b425f6d6ce mon: always load stashed version when version doesn't match 
The slurp process can happen after the monitor has started and has some
in-memory version of the state, and that process may wipe out old
incrementals and change the stashed version.  That means that in
update_from_paxos, we need to pull the stashed version if it doesn't
match what we currently have or else we may not have the incrementals we
need to get up to date.

This simplifies and cleans up that code a bit so it is not specific to
monitor startup.

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
