What are the implications of using the inode64 option while exporting XFS over NFS ?

Solution Unverified - Updated -

Issue

  • Are there any tuning recommendations for the XFS filesystem, NFS service and the amount of memory for this virtual machine to get optimal performance during data access or xfs_repair operations ?

  • We took a look into XFS FAQ and it looks like there may be trouble when not using INODE64 over NFS. Do you have any recommendations?

  • It looks like another parameter may work as well : The no_subtree_check option in /etc/exports. Do we have to set it up as well?

Environment

  • Red Hat Enterprise Linux 6.3
  • XFS file system
