Among other things, a stray/bad REPLAY flag can trigger a false activation like so: osd/PG.cc: In function 'void PG::activate(ObjectStore::Transaction&, std::list<Context*, std::allocator<Context*> >&, std::map<int, MOSDPGInfo*, std::less<int>, std::allocator<std::pair<const int, MOSDPGInfo*> > >*)': osd/PG.cc:1641: FAILED assert(peer_info.count(peer)) 1: (PG::activate(ObjectStore::Transaction&, std::list<Context*, std::allocator<Context*> >&, std::map<int, MOSDPGInfo*, std::less<int>, std::allocator<std::pair<int const, MOSDPGInfo*> > >*)+0x817) [0x75e637] 2: (OSD::activate_pg(pg_t, utime_t)+0x136) [0x6bfe86] 3: (OSD::check_replay_queue()+0x134) [0x6c0074] 4: (OSD::tick()+0x1db) [0x6d96eb] 5: (OSD::C_Tick::finish(int)+0x1c) [0x74844e] 6: (SafeTimer::EventWrapper::finish(int)+0x6d) [0x7fa2cf] 7: (Timer::timer_entry()+0x454) [0x7fb52a] 8: (Timer::TimerThread::entry()+0x19) [0x647c09] 9: (Thread::_entry_func(void*)+0x20) [0x659f18] 10: /lib/libpthread.so.0 [0x7fceb73d473a] 11: (clone()+0x6d) [0x7fceb65fe69d] |

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
