[DRBD-user] resource-and-stonith setting

[Pavlos Parissis]

Searching a bit more I found a thread[1] which was mentioned the following
disk {
        fencing resource-and-stonith;
        # this mode implicitly freezes IO and only resumes IO if peer is
        # successfully fenced as reported by the fence peer script.
        # Or if the admin explicitly resumes io.
}
handler {
        fence-peer "some script that kills the other node";
}


What is the benefit of freezing IO? Does that mean the FS on drbd disk
wont be accessible until fenced is completed?

Cheers,
Pavlos
