    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?
