Hi, md_do_sync() in md.c takes care not to resync/check MD devices built on different parts of the same physical device in parallel. This does not account for AoE devices, which, however, most of the time share and are limited by network bandwidth. Thus a monthly data check congests all AoE RAIDs at the same time. Don't you think this case should be handled specially, and such devices should be serialized by default (possibly overridden by parallel_resync, of course)? This could be implemented in match_mddev_units by returning true for any two AoE devices, for example. Or leaving that alone, and extending parallel_resync with a new option to force serialization. Maybe this would be more elegant. What do you think?
