Can you list the workload at the time, and also the mount options? To do sysrq+w as Liu Bo asks for, do this: echo 1 > /proc/sys/kernel/sysrq echo w > /proc/sysrq-trigger And then 'journalctl -k > kernel-sysrqw_btrfscleaner770blocked.txt' See if that will attach to the list, and if it's too big and bounces, put it up somewhere and post the URL. -- Chris Murphy -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
