From 5492c46e94b57b5137e3ba2c9ae22b2dcc3fc2cc Mon Sep 17 00:00:00 2001 From: Alexey Obitotskiy Date: Fri, 28 Jul 2017 15:49:25 +0200 Subject: md: notify about new spare disk in the container In case of external metadata arrays spare disks are added to containers first. mdadm keeps monitoring /proc/mdstat output and when spare disk is available, it moves it from the container to the array. The problem is there is no notification of new spare disk in the container and mdadm waits a long time (until timeout) before it takes the action.
