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

We can get a dentry that is trimmable (e.g. null) under a new unlinked dir, which has no subtree. This will only happen on the auth. In that case, having no container is harmless--it's only needed for replicas. This fixes the following crash: mds/MDCache.cc: In function 'void MDCache::trim_dentry(CDentry*, std::map<int, MCacheExpire*, std::less<int>, std::allocator<std::pair<const int, MCacheExpire*> > >&)': mds/MDCache.cc:4797: FAILED assert(con) 1: (MDCache::trim(int)+0x214) [0x4ffbc4] 2: (MDS::tick()+0x4c1) [0x48f3b1] 3: (SafeTimer::EventWrapper::finish(int)+0x269) [0x683a89] 4: (Timer::timer_entry()+0x819) [0x685909] 5: (Timer::TimerThread::entry()+0xd) [0x47528d] 6: (Thread::_entry_func(void*)+0x7) [0x48a8a7] 7: /lib/libpthread.so.0 [0x7ffe62356fc7] 8: (clone()+0x6d) [0x7ffe615835ad] NOTE: a copy of the executable, or `objdump -rdS <executable>` is needed to interpret this.

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:
mkmonfs -- create a fresh monfs (for a new filesystem)
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
