Title:
[18.04.1] Backport support for Intel VROC arrays in mdadm
Status in mdadm package in Ubuntu:
Fix Released
Status in mdadm source package in Bionic:
Fix Released
Status in mdadm source package in Cosmic:
Fix Released
Bug description:
[Impact]
 * mdadm as shipped in 18.04.0 does not support Intel VROC arrays, as
to be shipped over Bionic LTS lifecycle in multiple
laptop/desktop/server SKUs by multiple OEMs.
 * this is a request to backport mdadm master, with support of Intel
VROC arrays, and subsequent compiler fixes, and reshaping fixes, to
fully support VROC arrays (including reshaping).
[Test Cases]
 * Ensure existing Intel IMSM raids continue to assemble, boot, shutdown cleanly, bootable when degraded.
 * Ensure existing linux raids continue to assemble, boot, shutdown cleanly, bootable when degraded.
   - with 0.90 metadata; 1.0 metadata; 1.1 metadata; 1.2 metadata
 * [Optional] ensure that DDF raids continue to assemble, boot, shutdown cleanly, bootable when degraded.
 * Validate installers onto Intel IMSM raids
 * Validate installers onto Linux RAID
* Validate bare-metal public clouds that use mdadm
[Regression Potential]
 * Worst case scenario is failing to start assembled array in rw mode,
on boot. This would result in dropping into emergency shell/mode in
either initramfs, or emergency.target requiring manual intervention by
a sysadmin to recover and start synced raid array. However, the test
cases above should cover this regression potential adequately.
 * Other changes, to resizing/reshaping may result in failure to
resize/reshape, but these are rare maintenance operations for which
one should have a backup - or able to recover from such an operation.
[Other Info]
 * xnox offline 7th July - 16th July
