kern.maxswzone

Greetings,

OK I'm a bit confused here. It /sounds/ like you said you put 4.7 GIGabytes
on a 512 MEGabyte hard drive. Hmm, no that can't be right. I'll bet you
meant you have a computer with 512Mb RAM, and you created a 4.7Gb slice
for SWAP. OK, that probably exceeds the traditional 2.5 x RAM I remember
it being. But still, as memory serves, the message(s) you're seeing
won't have a definitive answer without first determining how large the
"block size" is on your hard drive. While I'm inclined to think they're
4096Kb. I can't know for sure, and anyone attempting to help, will also
need that number.
The block size determines the /amount/ (number) of pages the kernel creates.
