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

If we are a replica, the 'flushing' means that we had dirty scatterlock data and are waiting for it to get flushed out to the auth copy (by cycling from MIX->LOCK, normally). If we end up with 'flushing' set while in the MIX state, we can't wait for it to clear before responding to a lock request from the primary or we'll deadlock. On the auth, flushing means flushing to the log, which makes sense; that will always make progress despite scatterlock activity. This fixes a hang from 3-mds fsstress with thrashing exports. (Strangely I never hit this on fatty.) Signed-off-by: Sage Weil <sage@newdream.net> |

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
