These patches also 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: * not standarized yet, * the design is not settled with you, * generic grow routines are not compatible with change of chunk size. Please do not include these patches on 'master' branch, as they are supposed to be a part of next minor mdadm version (ie. mdadm 3.2.3). I think good place for them 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 | 343 +++++++++++++++++++++++++++++++++++++++++++++++++++++++-- 1 files changed, 333 insertions(+), 10 deletions(-) -- Best Regards, Przemyslaw Czarnowski
