There should be a line in the log specifying which assert is failing , post that along with say 10 lines from top of that..
Thanks & Regards Somnath From: ceph-users [mailto:ceph-users-boun...@lists.ceph.com] On Behalf Of Mansour Shafaei Moghaddam Sent: Wednesday, June 15, 2016 1:57 PM To: ceph-users@lists.ceph.com Subject: [ceph-users] Fio randwrite does not work on Centos 7.2 VM Hi All, Has anyone faced a similar issue? I do not have a problem with random read, sequential read, and sequential writes though. Everytime I try running fio for random writes, one osd in the cluster crashes. Here is the what I see at the tail of the log: ceph version 0.94.6 (e832001feaf8c176593e0325c8298e3f16dfb403) 1: ceph-osd() [0x9d6334] 2: (()+0xf100) [0x7fa2e88fb100] 3: (gsignal()+0x37) [0x7fa2e73145f7] 4: (abort()+0x148) [0x7fa2e7315ce8] 5: (__gnu_cxx::__verbose_terminate_handler()+0x165) [0x7fa2e7c189d5] 6: (()+0x5e946) [0x7fa2e7c16946] 7: (()+0x5e973) [0x7fa2e7c16973] 8: (()+0x5eb93) [0x7fa2e7c16b93] 9: (ceph::__ceph_assert_fail(char const*, char const*, int, char const*)+0x24a) [0xacd8ea] 10: (FileStore::_do_transaction(ObjectStore::Transaction&, unsigned long, int, ThreadPool::TPHandle*)+0xa24) [0x8b8114] 11: (FileStore::_do_transactions(std::list<ObjectStore::Transaction*, std::allocator<ObjectStore::Transaction*> >&, unsigned long, ThreadPool::TPHandle*)+0x64) [0x8bcf34] 12: (FileStore::_do_op(FileStore::OpSequencer*, ThreadPool::TPHandle&)+0x17e) [0x8bd0ce] 13: (ThreadPool::worker(ThreadPool::WorkThread*)+0xa56) [0xabe326] 14: (ThreadPool::WorkThread::entry()+0x10) [0xabf3d0] 15: (()+0x7dc5) [0x7fa2e88f3dc5] 16: (clone()+0x6d) [0x7fa2e73d528d] PLEASE NOTE: The information contained in this electronic mail message is intended only for the use of the designated recipient(s) named above.
