I followed the instructions in the FAQ on adding a vn-device to increase
swap size:
1. create a vn-device
cd /dev; sh ./MAKEDEV vn0
2. create a swapfile (/var/swap0)
dd if=/dev/zero of=/var/swap0 bs=1024k count=64
3. put into /etc/rc.local the line
vnconfig -ce /dev/vn0c /var/swap0 swap
Questions:
1. How can increase the size of /var/swap0 (the file)?
2. How can I disable swapping to the vn-device?
3. Is the performance of swapping/paging on a vn-device the same as on
a hard partition?
For the time being, I created another vn-device (vn1c) and another 64MB
file in /var (swap1) and vnconfig'd swap on it.
