Subject: Manage: allow manual control of external raid0 readonly flag
X-Git-Tag: mdadm-3.2~244
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9ea5a25217898a699a1ba0ba27693362f0d81456;p=thirdparty%2Fmdadm.git

Manage: allow manual control of external raid0 readonly flag

mdadm --readwrite <subarray> will clear the external readonly flag ('-'
to '/'), but only for redudant arrays.  Allow raid0 arrays as well so
the user has a simple helper to control this flag.
