I rebased wip-libcephfs and pushed as wip-libcephfs-emp-rb so that we can get this in to the Emperor release. Sage mentioned that he had hit a fuse problem in the wip-libcephfs branch, so apparently the problem is still present. Have you run into this bug in your testing? Are you testing with these modification to Ceph? 2013-10-04T10:39:01.664 INFO:teuthology.task.workunit.client.0.out:[10.214.132.22]: CC kernel/softirq.o 2013-10-04T10:39:02.059 INFO:teuthology.task.ceph-fuse.ceph-fuse.0.err:[10.214.132.22]: *** Caught signal (Segmentation fault) ** 2013-10-04T10:39:02.059 INFO:teuthology.task.ceph-fuse.ceph-fuse.0.err:[10.214.132.22]: in thread 7f57fa316780 2013-10-04T10:39:02.073 INFO:teuthology.task.ceph-fuse.ceph-fuse.0.err:[10.214.132.22]: ceph version 0.69-500-g09f4df0 (09f4df02a866230b19539b03061f4abc5ab47ae2) 2013-10-04T10:39:02.073 INFO:teuthology.task.ceph-fuse.ceph-fuse.0.err:[10.214.132.22]: 1: ceph-fuse() [0x5e0d1a] 2013-10-04T10:39:02.073 INFO:teuthology.task.ceph-fuse.ceph-fuse.0.err:[10.214.132.22]: 2: (()+0xfcb0) [0x7f57f9cc5cb0] 2013-10-04T10:39:02.073 INFO:teuthology.task.ceph-fuse.ceph-fuse.0.err:[10.214.132.22]: 3: (Client::_get_inodeno(Inode*)+0) [0x52dd10] 2013-10-04T10:39:02.073 INFO:teuthology.task.ceph-fuse.ceph-fuse.0.err:[10.214.132.22]: 4: (Client::ll_forget(Inode*, int)+0x4a) [0x538d1a] 2013-10-04T10:39:02.074 INFO:teuthology.task.ceph-fuse.ceph-fuse.0.err:[10.214.132.22]: 5: ceph-fuse() [0x52a1c5] 2013-10-04T10:39:02.074 INFO:teuthology.task.ceph-fuse.ceph-fuse.0.err:[10.214.132.22]: 6: (fuse_session_loop()+0x75) [0x7f57f9ee3d65] 2013-10-04T10:39:02.074 INFO:teuthology.task.ceph-fuse.ceph-fuse.0.err:[10.214.132.22]: 7: (main()+0x84c) [0x5266fc] 2013-10-04T10:39:02.074 INFO:teuthology.task.ceph-fuse.ceph-fuse.0.err:[10.214.132.22]: 8: (__libc_start_main()+0xed) [0x7f57f83f576d] 2013-10-04T10:39:02.074 INFO:teuthology.task.ceph-fuse.ceph-fuse.0.err:[10.214.132.22]: 9: ceph-fuse() [0x527c99] 2013-10-04T10:39:02.074 INFO:teuthology.task.ceph-fuse.ceph-fuse.0.err:[10.214.132.22]: 2013-10-04 10:39:02.072487 7f57fa316780 -1 *** Caught signal (Segmentation fault) ** 2013-10-04T10:39:02.074 INFO:teuthology.task.ceph-fuse.ceph-fuse.0.err:[10.214.132.22]: in thread 7f57fa316780 David Zafman Senior Developer http://www.inktank.com -- 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
