Can you be more specific about the 8TB limit? Is it correct that this
is an 8TB base 2 (8796GB base 10) limit?
Does this limit apply to the raw device size or formatted Lustre OST
size? Using RHEL5U1, we have created an OST on a 9.001 TB raw device
with a formatted size reported from lustre_config of 8584023MB. Is this
OST OK to use, or would we have receive an error message if it was not OK?
Thanks,
Bob
