What it means is that to absolutely protect shared disks against various
kinds of possible failures you ought to configure a STONITH device. For
that matter, you probably ought to configure a watchdog timer...
This is, of course, pretty much what it says.
And, since you're planning on using shared disks, then this warning
really applies to you.
The way to make the warning go away is to configure a STONITH device.
