[CentOS] XFS, inode64, and remount

[James A. Peltier]

| 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.)

With XFS there are a few options for which a simple remount will not work.  Quotas are another example where the option will not work unless you fully unmount the file system.
