The following series implements support for raid0->raid5 migration for IMSM metadata. These patches blocks opposite direction of migration. Code mostly bases on patches sent to you by Adam Kwolek. I have incorporated your remarks and I tested it quite extensively for comformity with IMSM standard. I have also removed opposite direction, as it is just not supported right now. Note: Please do not include these patches on 'master' branch, as they are supposed to be a part of next minor mdadm version (ie. mdadm 3.2.2). I think good place for it is devel-3.2. Master should be reserved just for bug/stability fixes for previous release. --- Przemyslaw Czarnowski (5): imsm: prepare update for level migrations reshape imsm: fix: disable migration from raid5->raid0 imsm: prepare memory for level migration update imsm: process update for raid level migrations imsm: add new chunk size to metadata update super-intel.c | 337 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++- 1 files changed, 330 insertions(+), 7 deletions(-) -- Best Regards, Przemyslaw Czarnowski
