I recently have been working with exporting ceph to NFS. I have had stability problems with NFS (ceph is working but NFS crashes). But most recently, my mds0 will not start after one of these instances with NFS. My setup. 2 mds, 1 mon (located on mds0), 5 osds. All running Ubuntu v10.10. Here is the output when I try to start the mds0. Is there other debugging I can turn on? /etc/init.d/ceph start mds0 2011-04-19 10:06:58.602640 7fb202fe4700 mds0.11 ms_handle_connect on 10.6.1.93:6800/945 ./include/elist.h: In function 'elist<T>::item::~item() [with T = MDSlaveUpdate*]', in thread '0x7fb2004d5700' ./include/elist.h: 39: FAILED assert(!is_on_list()) ceph version 0.26 (commit:9981ff90968398da43c63106694d661f5e3d07d5) 1: (MDSlaveUpdate::~MDSlaveUpdate()+0x59) [0x4d9fe9] 2: (ESlaveUpdate::replay(MDS*)+0x422) [0x4d2772] 3: (MDLog::_replay_thread()+0xb90) [0x67f850] 4: (MDLog::ReplayThread::entry()+0xd) [0x4b89ed] 5: (()+0x7971) [0x7fb20564a971] 6: (clone()+0x6d) [0x7fb2042e692d] ceph version 0.26 (commit:9981ff90968398da43c63106694d661f5e3d07d5) 1: (MDSlaveUpdate::~MDSlaveUpdate()+0x59) [0x4d9fe9] 2: (ESlaveUpdate::replay(MDS*)+0x422) [0x4d2772] 3: (MDLog::_replay_thread()+0xb90) [0x67f850] 4: (MDLog::ReplayThread::entry()+0xd) [0x4b89ed] 5: (()+0x7971) [0x7fb20564a971] 6: (clone()+0x6d) [0x7fb2042e692d] *** Caught signal (Aborted) ** in thread 0x7fb2004d5700 ceph version 0.26 (commit:9981ff90968398da43c63106694d661f5e3d07d5) 1: /usr/bin/cmds() [0x70fc38] 2: (()+0xfb40) [0x7fb205652b40] 3: (gsignal()+0x35) [0x7fb204233ba5] 4: (abort()+0x180) [0x7fb2042376b0] 5: (__gnu_cxx::__verbose_terminate_handler()+0x11d) [0x7fb204ad76bd] 6: (()+0xb9906) [0x7fb204ad5906] 7: (()+0xb9933) [0x7fb204ad5933] 8: (()+0xb9a3e) [0x7fb204ad5a3e] 9: (ceph::__ceph_assert_fail(char const*, char const*, int, char const*)+0x36a) [0x6f5eaa] 10: (MDSlaveUpdate::~MDSlaveUpdate()+0x59) [0x4d9fe9] 11: (ESlaveUpdate::replay(MDS*)+0x422) [0x4d2772] 12: (MDLog::_replay_thread()+0xb90) [0x67f850] 13: (MDLog::ReplayThread::entry()+0xd) [0x4b89ed] 14: (()+0x7971) [0x7fb20564a971] 15: (clone()+0x6d) [0x7fb2042e692d] I am not sure why the IP address of 0.0.0.0 shows up with starting the mds0. root@mds0:/var/log/ceph# /etc/init.d/ceph start mds0 === mds.0 === Starting Ceph mds.0 on mds0... ** WARNING: Ceph is still under heavy development, and is only suitable for ** ** testing and review.
