regarding the inode64 mount option

[Michael Weissenbacher]

Hi Eric + Christoph!

This is a scary list indeed! Does this apply only to Fedora on i686 or also to x86_64?

In general, does the inode64 option make sense at all on a partition that is <1TB in size?

Well, in my tests it didn't work. I tried this is on fedora core 6 with vanilla kernel 2.6.28.10 x86_64. See here:

The filesystem is consistent - xfs_check (3.0.1) doesn't report any problems.

thanks,
