Correct usage of inode64/running out of inodes

[Adam Donald <Adam.Donald@xxxxxxxxxxxxxxx>]

Hello

In short, I believe that I have used
the indode64 option correctly in mounting my XFS device on my Centos 5.2
system, however, I seem to only have 59 free inodes available and 7.5TB
of free space.  I would appreciate any insight as to what the best
approach would be to fix this situation.  In case it is helpful, I
have included output from various commands/files below, the XFS device
in question is /dev/mapper/VolGroup01-DATA01.  Thank you in advance
for your assistance!
