Chapter 54. File Systems
Mounting a non-existent NFS export outputs a different error than in RHEL 6
The
mount
utility prints the operation not permitted
error message when an NFS client is trying to mount a server export that does not exist. In Red Hat Enterprise Linux 6, the access denied
message was printed in the same situation. (BZ#1428549)
XFS disables per-inode DAX functionality
Per-inode direct access (DAX) options are now disabled in the XFS file system due to unresolved issues with this feature. XFS now ignores existing per-inode DAX flags on the disk.
You can still set file system DAX behavior using the
dax
mount option:
# mount -o dax device mount-point
(BZ#1623150)
