REVIEW: http://review.gluster.org/13343 (mount/fuse: get the inode from fuse inode number before accessing) posted (#1) for review on master by Raghavendra Bhat (raghavendra) http://review.gluster.org/13327 fixes the issue. So closing the bug. |
Description of problem: glusterfs client segfaults when an entry is invalidated via setfattr interface. This is the backtrace of the core generated. warning: .dynamic section for "/usr/local/lib/libglusterfs.so.0" is not at the expected address (wrong library or version mismatch?) [Thread debugging using libthread_db enabled] Using host libthread_db library "/lib64/libthread_db.so.1". Core was generated by `/usr/local/sbin/glusterfs --volfile-server=hal9000 --volfile-id=mirror /mnt/glu'.
