Pardon my ignorance but does the number of inodes in the filesystem have a
significant impact on the memory requirement of fsck?

I ask as it was previously stated the smallest file on the 10TB filessytem
would be 500MB which would enable a vastley reduced number of inodes and
possibly very large block fragment and cluster sizes?
