[aclug-L] Re: Dual swap partitions

[David Duffey <email@xxxxxxxxxxxxxxx>]

add another entry in your /etc/fstab, make sure you initialize it first

# mkswap /dev/hdaWHATEVER
# vi /etc/fstab  # duplicate the swap line
# swapon -a

there should be no performance loss if they have different priorities, the
default behavior (one will be used before the other)

if you manually set their priorities (with option pri=#) to be the same
value then it will try to use them both at the same time.  Since in your case
they are on the same disk you would see very horrible performance.
