There are a bunch of FAQ entries at the XFS site about this issue.
Here's one of them:
http://xfs.org/index.php/XFS_FAQ#Q:_What_is_the_inode64_mount_option_for.3F
The other issues about using inode64 and NFS are also nearby on the
same page.
So following up on that, I have a question: I have a largish XFS
filesystem which is currently not mounted inode64. I would like to know
how close I am to filling up the inodes in the first 1TB, so that I know
how urgent it is for me to migrate to inode64. Does anybody know a way
to query this information out of the filesystem?

I have read on the mailing lists that the XFS folks recommend using
xfs_repair -n over xfs_check. xfs_repair still needs a lot of RAM, but
apparently xfs_check needs much more.
