Hi all,

I was recently poking more into the inode64 mount option for XFS
filesystems.  I seem to recall a comment that you could remount a
filesystem with inode64, but then a colleague ran into issues where he
did that but was still out of inodes.  So, I did more research, and
found this posting to the XFS list:

http://oss.sgi.com/archives/xfs/2008-05/msg01409.html

So for people checking the CentOS list archives, I hope this comes up in
a search.  (It was not easy to find the above post!)  You must umount
and re-mount an XFS filesystem in order to have the inode64 option work
properly; a simple mount -o remount,inode64 is not sufficient.  (That
posting is a bit old; if I have a chance I will check in on the XFS
mailing list.)
