One of the scenarios where ceph-fuse segfaults is when a user submits a parallel (mpi) application requesting 4 hosts with 4 cores each (16 instances in total) . According to the user, each instance has its own dedicated inputs and outputs. > > Please note that if we go back to ceph-fuse 9.2.0 client everything works fine. > > The ceph-fuse 10.2.2 client segfault is the following (we were able to capture it mounting ceph-fuse in debug mode): >> >> 2016-07-04 21:21:00.074087 7f6aed92be40 0 ceph version 10.2.2 (45107e21c568dd033c2f0a3107dec8f0b0e58374), process ceph-fuse, pid 7346 >> ceph-fuse[7346]: starting ceph client >> 2016-07-04 21:21:00.107816 7f6aed92be40 -1 init, newargv = 0x7f6af8c12320 newargc=11 >> ceph-fuse[7346]: starting fuse >> *** Caught signal (Segmentation fault) ** >> in thread 7f69d7fff700 thread_name:ceph-fuse >> ceph version 10.2.2 (45107e21c568dd033c2f0a3107dec8f0b0e58374) >> 1: (()+0x297ef2) [0x7f6aedbecef2] >> 2: (()+0x3b88c0f7e0) [0x7f6aec64b7e0] >> 3: (Client::get_root_ino()+0x10) [0x7f6aedaf0330] >> 4: (CephFuse::Handle::make_fake_ino(inodeno_t, snapid_t)+0x175) [0x7f6aedaee035] >> 5: (()+0x199891) [0x7f6aedaee891] >> 6: (()+0x15b76) [0x7f6aed50db76] >> 7: (()+0x12aa9) [0x7f6aed50aaa9] >> 8: (()+0x3b88c07aa1) [0x7f6aec643aa1] >> 9: (clone()+0x6d) [0x7f6aeb8d193d] >> 2016-07-05 10:09:14.045131 7f69d7fff700 -1 *** Caught signal (Segmentation fault) ** >> in thread 7f69d7fff700 thread_name:ceph-fuse >> >> ceph version 10.2.2 (45107e21c568dd033c2f0a3107dec8f0b0e58374) >> 1: (()+0x297ef2) [0x7f6aedbecef2] >> 2: (()+0x3b88c0f7e0) [0x7f6aec64b7e0] >> 3: (Client::get_root_ino()+0x10) [0x7f6aedaf0330] >> 4: (CephFuse::Handle::make_fake_ino(inodeno_t, snapid_t)+0x175) [0x7f6aedaee035] >> 5: (()+0x199891) [0x7f6aedaee891] >> 6: (()+0x15b76) [0x7f6aed50db76] >> 7: (()+0x12aa9) [0x7f6aed50aaa9] >> 8: (()+0x3b88c07aa1) [0x7f6aec643aa1] >> 9: (clone()+0x6d) [0x7f6aeb8d193d] >> NOTE: a copy of the executable, or `objdump -rdS <executable>` is needed to interpret this. >> >> > The full dump is quite long.
