From 329dfc28debb58ffe7bd1967cea00fc583139aca Mon Sep 17 00:00:00 2001

Subject: [PATCH] Create: add support for RAID0 layouts.
Git-commit: 329dfc28debb58ffe7bd1967cea00fc583139aca
Patch-mainline: mdadm-4.1+
References: bsc#1162479
Since Linux 5.4 a layout is needed for RAID0 arrays with
varying device sizes.
This patch makes the layout of an array visible (via --examine)
and sets the layout on newly created arrays.
--layout=dangerous
can be used to avoid setting a layout so that they array
can be used on older kernels.

Subject: [PATCH v3] mdadm.8: add note information for raid0 growing operation
Patch-mainline: Not yet, waiting for maintainer to merge
References: bsc#1129900
When growing a raid0 device, if the new component disk size is not
big enough, the grow operation may fail due to lack of backup space.
The minimum backup space should be larger than
LCM(old, new) * chunk-size * 2
where LCM() is the least common multiple of the old and new count of
component disks, and "* 2" comes from the fact that mdadm refuses to
use more than half of a spare device for backup space.
There are users reporting such failure when they grew a raid0 array
with small component disk. Neil Brown points out this is not a bug
and how the failure comes. This patch adds note information into
mdadm(8) man page in the Notes part of GROW MODE section, to explain
the minimum size requirement of new component disk size or external
backup size.
