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

Make all survivors participate in resolve stage, so that survivors can properly determine the outcome of migrations to the failed node that did not complete. The sequence (before): - A starts to export /foo to B - C has ambiguous auth (A,B) in it's subtree map - B journals import_start - B fails ... - B restarts - B sends resolves to everyone - does not claim /foo - A sends resolve _only_ to B - does claim /foo - B knows it's import did not complete - C doesn't know anything. Also, the maybe_resolve_finish stuff was totally broken because the recovery_set wasn't initialized See new (commented out) assert in Migrator.cc to reproduce the above.

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
