From 3bf9495270d7cd00da942e183dc5f7c7eb68ff69 Mon Sep 17 00:00:00 2001 From: Mariusz Tkaczyk Date: Thu, 11 Jan 2018 12:39:49 +0100 Subject: [PATCH] policy.c: Avoid to take spare without defined domain by imsm Only Imsm get_disk_controller_domain returns disk controller domain for each disk. It causes that mdadm automatically creates disk controller domain policy for imsm metadata, and imsm containers in the same disk controller domain can take spare for recovery. Ignore spares if only one imsm domain is matched.
