I need to add the inode64, and nobarrier options to /etc/fstab. Are they valid options to just add in under the fourth column? Looking at the fstab man page it points to the mount manpage for options, but this doesn't have either of them listed (http://linux.die.net/man/8/mount). Any help would be appreciated. Thanks!
They are valid in that location. I was using nobarrier on a server for an XFS file-system for a number of years without issue. And inode64 does show up in newer man-pages.
