Hi, I've a libvirt-VM that gets format 2 rbd-childs 'fed' by the superhost. It crashed recently with this in the logs: osdc/ObjectCacher.cc: In function 'void ObjectCacher::bh_write_commit(int64_t, sobject_t, loff_t, uint64_t, tid_t, int)' thread 7f0cab5fd700 time 2013-03-01 22:02:37.374410 osdc/ObjectCacher.cc: 834: FAILED assert(ob->last_commit_tid < tid) ceph version 0.56.3 (6eb7e15a4783b122e9b0c85ea9ba064145958aa5) 1: (ObjectCacher::bh_write_commit(long, sobject_t, long, unsigned long, unsigned long, int)+0xd68) [0x7f0d087cda28] 2: (ObjectCacher::C_WriteCommit::finish(int)+0x6b) [0x7f0d087d460b] 3: (Context::complete(int)+0xa) [0x7f0d0878c9fa] 4: (librbd::C_Request::finish(int)+0x85) [0x7f0d087bc325] 5: (Context::complete(int)+0xa) [0x7f0d0878c9fa] 6: (librbd::rados_req_cb(void*, void*)+0x47) [0x7f0d087a1387] 7: (librados::C_AioSafe::finish(int)+0x1d) [0x7f0d07b5834d] 8: (Finisher::finisher_thread_entry()+0x1c0) [0x7f0d07bc20d0] 9: (()+0x7e9a) [0x7f0d0546be9a] 10: (clone()+0x6d) [0x7f0d05198cbd] NOTE: a copy of the executable, or `objdump -rdS <executable>` is needed to interpret this. terminate called after throwing an instance of 'ceph::FailedAssertion' Any clue why that happened? -- DI (FH) Wolfgang Hennerbichler Software Development Unit Advanced Computing Technologies RISC Software GmbH A company of the Johannes Kepler University Linz IT-Center Softwarepark 35 4232 Hagenberg Austria Phone: +43 7236 3343 245 Fax: +43 7236 3343 250 wolfgang.hennerbichler@xxxxxxxxxxxxxxxx http://www.risc-software.at -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
