That's significantly bigger than what I have running, but I have heard
of people running XFS on larger filesystems than I have.
If you're making one large filesystem out of that, the warning James
mentioned is even more important: you will want a boatload of memory to
xfs_repair that fs quickly. The rough rule of thumb I've read (which is
probably akin to the 2x RAM==swap guideline) is at least 1GB of memory
for every 1TB of storage, but the more the better, I'd wager.
