From 69d084784de196acec8ab703cd1b379af211d624 Mon Sep 17 00:00:00 2001 From: Artur Paszkiewicz Date: Fri, 22 Feb 2019 10:15:45 +0100 Subject: [RHEL7.7 PATCH 18/24] mdmon: don't attempt to manage new arrays when terminating When mdmon gets a SIGTERM, it stops managing arrays that are clean. If there is more that one array in the container and one of them is dirty and the clean one is still present in mdstat, mdmon will treat it as a new array and start managing it again. This leads to a cycle of remove_old() / manage_new() calls for the clean array, until the other one also becomes clean. Prevent this by not calling manage_new() if sigterm is set. Also, remove a check for sigterm in manage_new() because the condition will never be true.
