Subject: [RHEL7.7 PATCH 18/24] mdmon: don't attempt to manage new arrays when
|
|
|
8fbece |
terminating
|
|
|
8fbece |
|
|
|
8fbece |
When mdmon gets a SIGTERM, it stops managing arrays that are clean. If
|
|
|
8fbece |
there is more that one array in the container and one of them is dirty
|
|
|
8fbece |
and the clean one is still present in mdstat, mdmon will treat it as a
|
|
|
8fbece |
new array and start managing it again. This leads to a cycle of
|
|
|
8fbece |
remove_old() / manage_new() calls for the clean array, until the other
|
|
|
8fbece |
one also becomes clean.
|
|
|
8fbece |
|
|
|
8fbece |
Prevent this by not calling manage_new() if sigterm is set. Also, remove
|
|
|
8fbece |
a check for sigterm in manage_new() because the condition will never be
|
|
|
8fbece |
true.
