Subject: Allow "--write-behind=" to be done in grow mode.

X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=7d19ad0de31cd0b94e69ac5f2efee98254f27316;p=thirdparty%2Fmdadm.git

Allow "--write-behind=" to be done in grow mode.

From: Ian Dall <ian@beware.dropbear.id.au>

I have a small patch to mdadm which allows the write-behind amount to be
set a array grow time (instead of currently only at grow or create
time). I have tested this fairly extensively on some arrays built out of
loop back devices, and once on a real live array.
