:Okay, just to confirm, my swap device looks like:
:
:venus# pstat -s
:Device 1K-blocks Used Avail Capacity Type
:/dev/amrd0s1b 2097024 8708 2088316 0% Interleaved

pstat -s reports 128K less then the actual size of the
partition, so you have 2097152 = 2G exactly. 2048m
should be fine.
Yes, setting dumpdev="/dev/amrd0s1b" in /etc/rc.conf should do
it.
