* Super1: allow RAID0 layout setting to be removed.NeilBrown2020-10-141-0/+13
| | | | | | | | | | | | | | | | Once the RAID0 layout has been set, the RAID0 array cannot be assembled on an older kernel which doesn't understand layouts. This is an intentional safety feature, but sometimes people need the ability to roll-back to a previously working configuration. So add "--update=layout-unspecified" to remove RAID0 layout information from the superblock. Running "--assemble --update=layout-unspecified" will cause the assembly the fail when run on a newer kernel, but will allow it to work on an older kernel.

* Assemble: add support for RAID0 layouts.NeilBrown2019-12-021-0/+7
| | | | | | | | | | | | | If you have a RAID0 array with varying sized devices on a kernel before 5.4, you cannot assembling it on 5.4 or later without explicitly setting the layout. This is now possible with --update=layout-original (For 3.13 and earlier kernels) or --update=layout-alternate (for 3.14 and later kernels) Signed-off-by: NeilBrown <neilb@suse.de> Signed-off-by: Jes Sorensen <jsorensen@fb.com>
* Create: add support for RAID0 layouts.NeilBrown2019-12-021-0/+14
| | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | Allow per-device "failfast" flag to be set when creating an array or adding devices to an array. When re-adding a device which had the failfast flag, it can be removed using --nofailfast. failfast status is printed in --detail and --examine output.
