Ceph is a distributed object, block, and file storage platform

Currently mkdir foo ; rmdir foo fails because we can't get_subtree_map() on a new directory that isn't linked in the committed plane. Since we are journaling the projected subtree, it makes sense to use get_projected_subtree_map() here. It's easiest to keep in both the old and new directories in the rename project map instead of looking at the next-to-most-recent parent for the inode. The committed version is irrelevant (could conceivably be multiple renames behind) and the current projected parent is just newdir; we need olddir too, and we don't project for cross-mds rename anyway.

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
