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.
