Close, it's 1TB.  But you won't be able to create *any* new inodes,
directories or files.


The FAQ suggests using inode64 for any filesystem larger than 1TB.  You
can probably get away with not using it for larger filesystems unless
you're planning on having half of your filesystem be inodes.  But 66TB
practically requires inode64; it'd be insane not to use it.

Are you exporting the root of the filesystem or using a nondefault fsid


I think that if you're exporting a 66TB filesystem, and exporting to a
32bit client doesn't work, then you have to bite the bullet and not
allow the 32bit client, or do something like create a smaller filesystem
to export for 32bit clients.  You really can't have such a large
filesystem and not use inode64.
