I tried the unstable version on Saturday, which looks a lot better, but I am still facing similar issues: - The first one is when writing files, I usually get the message from cfuse, 10.07.17_23:13:12.117289 42f16940 client4213.objecter pg 0.90ea on [1,0] is laggy: 51723 10.07.17_23:13:12.117302 42f16940 client4213.objecter pg 0.4194 on [1,0] is laggy: 51722 - In some cases, cfuse (I turned off daemonizing) crushes, again when writing on the filesystem, but not due to xlist: osdc/ObjectCacher.cc: In function 'void ObjectCacher::bh_write_ack(sobject_t, loff_t, uint64_t, tid_t)': osdc/ObjectCacher.cc:670: FAILED assert(ob->last_ack_tid < tid) 1: (ObjectCacher::bh_write_ack(sobject_t, long, unsigned long, unsigned long)+0x6a8) [0x6b2bc2] 2: (ObjectCacher::C_WriteAck::finish(int)+0x57) [0x6c955b] 3: (Objecter::handle_osd_op_reply(MOSDOpReply*)+0xbd1) [0x688f07] 4: (Client::ms_dispatch(Message*)+0xd8) [0x61f4ca] 5: (Messenger::ms_deliver_dispatch(Message*)+0x55) [0x5ff0b7] 6: (SimpleMessenger::dispatch_entry()+0x50f) [0x5ea2e7] 7: (SimpleMessenger::DispatchThread::entry()+0x29) [0x5e8a1f] 8: (Thread::_entry_func(void*)+0x20) [0x5f8c0a] 9: /lib64/libpthread.so.0 [0x3d7420673d] 10: (clone()+0x6d) [0x3d736d3d1d] NOTE: a copy of the executable, or `objdump -rdS <executable>` is needed to interpret this. osdc/ObjectCacher.cc: In function 'void ObjectCacher::bh_write_ack(sobject_t, loff_t, uint64_t, tid_t)': osdc/ObjectCacher.cc:670: FAILED assert(ob->last_ack_tid < tid) 1: (ObjectCacher::bh_write_ack(sobject_t, long, unsigned long, unsigned long)+0x6a8) [0x6b2bc2] 2: (ObjectCacher::C_WriteAck::finish(int)+0x57) [0x6c955b] 3: (Objecter::handle_osd_op_reply(MOSDOpReply*)+0xbd1) [0x688f07] 4: (Client::ms_dispatch(Message*)+0xd8) [0x61f4ca] 5: (Messenger::ms_deliver_dispatch(Message*)+0x55) [0x5ff0b7] 6: (SimpleMessenger::dispatch_entry()+0x50f) [0x5ea2e7] 7: (SimpleMessenger::DispatchThread::entry()+0x29) [0x5e8a1f] 8: (Thread::_entry_func(void*)+0x20) [0x5f8c0a] 9: /lib64/libpthread.so.0 [0x3d7420673d] 10: (clone()+0x6d) [0x3d736d3d1d] NOTE: a copy of the executable, or `objdump -rdS <executable>` is needed to interpret this. terminate called after throwing an instance of 'ceph::FailedAssertion*' Aborted - Finally, I don't get what's wrong with deleting.
