      Sometimes user doesn't want the max_sectors_kb being overwritten on MDT/OST mount, we should provide a way for user to have more control over this important parameter, a environment variable MOUNT_LUSTRE_MAX_SECTORS_KB is introduced for this purpose:

      • When MOUNT_LUSTRE_MAX_SECTORS_KB isn't set, change the max_sectors_kb to max_hw_sectors_kb;
      • When MOUNT_LUSTRE_MAX_SECTORS_KB is set to 0 or a non-decimal value, leave the old max_sectors_kb setting untouched;
      • When MOUNT_LUSTRE_MAX_SECTORS_KB is set to a valid decimal value, change the max_sectors_kb to this value;
