Looking back at the original messages: [4038193.380403] INFO: task md2_raid5:247 blocked for more than 120 seconds. [4038193.380473] Not tainted 4.4.0-81-generic #104~14.04.1-Ubuntu [4038193.380526] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message. it looks like you're dealing with this part of the kernel: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/kernel/hung_task.c The timer is configurable with sysctl and defaults to 120 seconds. You can check with this command: $ sudo sysctl kernel.hung_task_timeout_secs kernel.hung_task_timeout_secs = 120 You can adjust it temporarily (e.g. to make it longer): $ sudo sysctl -w kernel.hung_task_timeout_secs=150 Or you can adjust it permanently by modifying your sysctl configuration. It looks like by default it will only warn ten times. After that it will stop complaining. That is also configurable via sysctl.
