Hi all, I am working on a research project which requires multiple write operations for the same object at the same time from the client. At the OSD side, I got this error: osd/ReplicatedPG.cc: In function 'int ReplicatedPG::find_object_context(const hobject_t&, ObjectContextRef*, bool, bool, hobject_t*)' thread 7f0586193700 time 2016-07-21 14:02:04.218448 osd/ReplicatedPG.cc: 9041: FAILED assert(oid.pool == static_cast<int64_t>(info.pgid.pool())) ceph version 10.2.0-2562-g0793a28 (0793a2844baa38f6bcc5c1724a1ceb9f8f1bbd9c) 1: (ceph::__ceph_assert_fail(char const*, char const*, int, char const*)+0x8b) [0x7f059fe6dd7b] 2: (ReplicatedPG::find_object_context(hobject_t const&, std::shared_ptr<ObjectContext>*, bool, bool, hobject_t*)+0x1dbb) [0x7f059f9296fb] 3: (ReplicatedPG::do_op(std::shared_ptr<OpRequest>&)+0x186e) [0x7f059f959d7e] 4: (ReplicatedPG::do_request(std::shared_ptr<OpRequest>&, ThreadPool::TPHandle&)+0x73c) [0x7f059f916a0c] 5: (OSD::dequeue_op(boost::intrusive_ptr<PG>, std::shared_ptr<OpRequest>, ThreadPool::TPHandle&)+0x3f5) [0x7f059f7ced65] 6: (PGQueueable::RunVis::operator()(std::shared_ptr<OpRequest> const&)+0x5d) [0x7f059f7cef8d] 7: (OSD::ShardedOpWQ::_process(unsigned int, ceph::heartbeat_handle_d*)+0x86c) [0x7f059f7f003c] 8: (ShardedThreadPool::shardedthreadpool_worker(unsigned int)+0x947) [0x7f059fe5e007] 9: (ShardedThreadPool::WorkThreadSharded::entry()+0x10) [0x7f059fe60160] 10: (()+0x8184) [0x7f059e2d2184] 11: (clone()+0x6d) [0x7f059c1e337d] And at the client side, I got segmentation fault. I am wondering what will be the possible reason that cause the assert fail?
