Do not apply bulk IO tuning on MDT or MGT devices

Details

    • 9223372036854775807

    Description

      The max_sectors_kb tunable should not be applied to MDT and MGT devices. This tuning is needed for efficiency of large IO submission for spinning disks, but is not needed for SSDs or regular IO. It can cause problems with DM Multipath configurations for minimal benefits, so should be limited to OST devices.

            Not really, just need to put the OST check hunk at the top of set_blockdwv_tunables() after the initial sanity checks.
