Sage Weil b7c4185793 mds: do full pre_dirty()/mark_dirty() on cowed dentries 
The dir commit/fetch and LogSegment::try_to_expire() rely on any new or
items in the directory getting new versions that correspond to a bump in
the dirfrag version.  This must include dentries/inodes that are created
by the cow process, or else we have problems during dir commit/fetch or
segment expire.

Change the dirty list in the Mutation to include the pv so that we can
properly mark them dirty later.

Leave the inode one alone.  We could theoretically do the same for the
dirty inodes, but this way we avoid projecting them and copying stuff
around.  Any dirty cowed inode will also have a dirty dentry, so it will
still get saved regardless.

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
