XFS, Inode64, And Remount

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:

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.
