Here is how the feature is broken on NetBSD: setting split-brain-resolution.t causes afr inode context's spb_choice to be set to the desired source. That works. But when I try to read from the file, spb_choice is -1. This is because in the meantime, the context has been destroyed by afr_destroy() and reallocated with sbp_choice set to default value -1. Since spb_choice is not saved as an attribute for the file on the bricks, it cannot be recovered when the context is reallocated. Either that "save" feature has been forgotten, or going to afr_destroy() here is a bug. Here is the backtrace leading there: 0xbb751313 <_gf_msg_backtrace_nomem+0xc0> at /autobuild/install/lib/libglusterfs.so.0 0xb9b441af <afr_forget+0x89> at /autobuild/install/lib/glusterfs/3.7dev/xlator/cluster/replicate.so 0xbb771801 <gf_timer_registry_destroy+0xc58> at /autobuild/install/lib/libglusterfs.so.0 0xbb7718af <gf_timer_registry_destroy+0xd06> at /autobuild/install/lib/libglusterfs.so.0 0xbb773a38 <inode_table_set_lru_limit+0x16a> at /autobuild/install/lib/libglusterfs.so.0 0xbb771dd4 <inode_unref+0x5d> at /autobuild/install/lib/libglusterfs.so.0 0xbb277518 <fuse_lookup_resume+0x723> at /autobuild/install/lib/glusterfs/3.7dev/xlator/mount/fuse.so 0xbb277639 <fuse_lookup_resume+0x844> at /autobuild/install/lib/glusterfs/3.7dev/xlator/mount/fuse.so 0xbb28d70f <fuse_get_mount_status+0x7af> at /autobuild/install/lib/glusterfs/3.7dev/xlator/mount/fuse.so 0xbb6a2bca <__libc_thr_exit+0x1f8> at /usr/lib/libpthread.so.1 -- Emmanuel Dreyfus http://hcpnet.free.fr/pubz manu@xxxxxxxxxx _______________________________________________ Gluster-devel mailing list Gluster-devel@xxxxxxxxxxx http://www.gluster.org/mailman/listinfo/gluster-devel
