Hi Sage and all, I build ceph code from wip-newstore on RHEL7 and running performance tests to compare with filestore. After few hours of running the tests the osd daemons started to crash. Here is the stack trace, the osd crashes immediately after the restart. So I could not get the osd up and running.
ceph version b8e22893f44979613738dfcdd40dada2b513118 (eb8e22893f44979613738dfcdd40dada2b513118) 1: /usr/bin/ceph-osd() [0xb84652] 2: (()+0xf130) [0x7f915f84f130] 3: (gsignal()+0x39) [0x7f915e2695c9] 4: (abort()+0x148) [0x7f915e26acd8] 5: (__gnu_cxx::__verbose_terminate_handler()+0x165) [0x7f915eb6d9d5] 6: (()+0x5e946) [0x7f915eb6b946] 7: (()+0x5e973) [0x7f915eb6b973] 8: (()+0x5eb9f) [0x7f915eb6bb9f] 9: (ceph::__ceph_assert_fail(char const*, char const*, int, char const*)+0x27a) [0xc84c5a] 10: (NewStore::collection_list_partial(coll_t, ghobject_t, int, int, snapid_t, std::vector<ghobject_t, std::allocator<ghobject_t> >*, ghobject_t*)+0x13c9) [0xa08639] 11: (PGBackend::objects_list_partial(hobject_t const&, int, int, snapid_t, std::vector<hobject_t, std::allocator<hobject_t> >*, hobject_t*)+0x352) [0x918a02] 12: (ReplicatedPG::do_pg_op(std::tr1::shared_ptr<OpRequest>)+0x1066) [0x8aa906] 13: (ReplicatedPG::do_op(std::tr1::shared_ptr<OpRequest>&)+0x1eb) [0x8cd06b] 14: (ReplicatedPG::do_request(std::tr1::shared_ptr<OpRequest>&, ThreadPool::TPHandle&)+0x68a) [0x85dbea] 15: (OSD::dequeue_op(boost::intrusive_ptr<PG>, std::tr1::shared_ptr<OpRequest>, ThreadPool::TPHandle&)+0x3ed) [0x6c3f5d] 16: (OSD::ShardedOpWQ::_process(unsigned int, ceph::heartbeat_handle_d*)+0x2e9) [0x6c4449] 17: (ShardedThreadPool::shardedthreadpool_worker(unsigned int)+0x86f) [0xc746bf] 18: (ShardedThreadPool::WorkThreadSharded::entry()+0x10) [0xc767f0] 19: (()+0x7df3) [0x7f915f847df3] 20: (clone()+0x6d) [0x7f915e32a01d] NOTE: a copy of the executable, or `objdump -rdS <executable>` is needed to interpret this. Please let me know the cause of this crash, when this crash happens I noticed that two osds on separate machines are down. I can bring one osd up but restarting the other osd causes both OSDs to crash. My understanding is the crash seems to happen when two OSDs try to communicate and replicate a particular PG.
