Greg Farnum bc273957af AnchorServer: overwrite old Anchor backpointers when proper.
Sometimes when we do an AnchorTable update, it's because the inode
in question got moved. However, if the inode had multiple references,
its Anchor wasn't removed by decrementing its count, and so the add
function simply noted that it already had the Anchor and returned.

This obviously wasn't the proper behavior in cases where the inode
was getting moved -- we want to update its back pointer! So do so.

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
