The volume option is for the NFS-server only. It does not affect the 
GlusterFS-native mount, therefore there is no need to set this option for the 
volume.

This is the correct usage.

Are you using the version with the patch on the client? The conversion of the 
64-bit to 32-bit inodes is done client-side, not server-side. This makes it 
possible for clients to choose if they want/need 32- or 64-bit inodes.

Cheers,
