The MD driver does not support the standard block device ioctl
BLKSSZGET, but the assumtion 512 byte hard sector size hold true.
The script does a basic sanity check for your configuration, and
gives you a hint about what it thinks the local lower level
physical device size is. You might need to set it lower than
that, because it is possible that the other nodes lower level
physical device is smaller.

With linux 2.4 the same as for the linux kernel: 2TB.
With 2.6: even more than enough ...
This has nothing to do with the message above, though.
