RHEL 7 DM-Multipath guide:

https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/DM_Multipath/move_swap_to_multipath.html

Section Number and Name: 
5.4. Moving swap File Systems from a Single Path Device to a Multipath Device

Describe the issue: 

In above section of dm-multipath guide, there is following example entry mentioned in step 3:

<snip>
	Edit the /etc/fstab file and replace the old device path to the root device with the multipath device.
	For example, if you had the following entry in the /etc/fstab file:

	/dev/sda2 swap                    ext4    defaults        0 0

	You would change the entry to the following:

	/dev/mapper/swapdev swap          ext4    defaults        0 0
<snip>


Above entry has a small problem. These entries are for swap filesystem, but still there is ext4 mentioned for it.

Suggestions for improvement: 

The correct entries for swap filesystems in above section would be:

	/dev/sda2 swap                    swap    defaults        0 0

and 

	/dev/mapper/swapdev swap          swap    defaults        0 0

Fix made in working copy of document. This will be on the Portal at 7.3, or earlier if there is an interim build.
