Hi OCFS2 experts, I found a strange segment of code during FENCE procedure in function o2hb_stop_all_regions, cited as below: void o2hb_stop_all_regions(void) { struct o2hb_region *reg; mlog(ML_ERROR, "stopping heartbeat on all active regions.\n"); spin_lock(&o2hb_live_lock); list_for_each_entry(reg, &o2hb_all_regions, hr_all_item) reg->hr_unclean_stop = 1; spin_unlock(&o2hb_live_lock); } In this preceding code segment, all o2hb regions' hr_unclean_stop is set to 1, just before an emergency reboot. So it's hard to figure out if other threads have a chance to work according to the value of it. Can we just remove the assignment? BR.
