Hey folks, We were hoping this one was fixed. I upgraded all my nodes to the latest bobtail branch, but still hit this today: osdc/ObjectCacher.cc: In function 'void ObjectCacher::bh_write_commit(int64_t, sobject_t, loff_t, uint64_t, tid_t, int)' thread 7f650e62f700 time 2013-03-20 19:34:39.952616 osdc/ObjectCacher.cc: 834: FAILED assert(ob->last_commit_tid < tid) ceph version 0.56.3-42-ga30903c (a30903c6adaa023587d3147179d6038ad37ca520) 1: (ObjectCacher::bh_write_commit(long, sobject_t, long, unsigned long, unsigned long, int)+0xd68) [0x7f651d0ada48] 2: (ObjectCacher::C_WriteCommit::finish(int)+0x6b) [0x7f651d0b460b] 3: (Context::complete(int)+0xa) [0x7f651d06c9fa] 4: (librbd::C_Request::finish(int)+0x85) [0x7f651d09c315] 5: (Context::complete(int)+0xa) [0x7f651d06c9fa] 6: (librbd::rados_req_cb(void*, void*)+0x47) [0x7f651d081387] 7: (librados::C_AioSafe::finish(int)+0x1d) [0x7f651c43163d] 8: (Finisher::finisher_thread_entry()+0x1c0) [0x7f651c49c920] 9: (()+0x7e9a) [0x7f6519cffe9a] 10: (clone()+0x6d) [0x7f6519a2bcbd] NOTE: a copy of the executable, or `objdump -rdS <executable>` is needed to interpret this. Is this occuring in librbd caching? If so, I could disable it for the time being. First saw this mentioned on-list here: http://thread.gmane.org/gmane.comp.file-systems.ceph.devel/13577 Will be happy to provide anything I can for this one -- definitely critical for my use case. It happens with about 10% of the VMs I create. Always within the first 60 seconds of the VM booting and being network accessible. - Travis -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
