# Making a Swap File
|
|
|
|
```sh
|
|
su root
|
|
cd /var/cache/
|
|
dd if=/dev/zero of=swapfile bs=1K count=4M
|
|
```
|
|
|
|
This creates a swapfile of (1k x 4M) 4 Gigs.
|
|
Change 4M to XM for an XGig swap.
|
|
|
|
```sh
|
|
chmod 600 swapfile
|
|
```
|
|
|
|
```sh
|
|
mkswap swapfile
|
|
```
|
|
|
|
```sh
|
|
swapon swapfile
|
|
```
|
|
|
|
Test it's working with top
|
|
|
|
```sh
|
|
top -bn1 | grep -i swap
|
|
```
|
|
|
|
or:
|
|
|
|
```sh
|
|
echo "/var/cache/swapfile none swap sw 0 0" | tee -a /etc/fstab
|
|
```
|
|
|
|
Test it'll work at boot with:
|
|
|
|
```sh
|
|
swapoff swapfile
|
|
```
|
|
|
|
```sh
|
|
swapon -va
|
|
```
|
|
|
|
# Partition Swaps
|
|
|
|
Put this in /etc/fstab:
|
|
|
|
> UUID=blah-blah none swap sw 0 0
|
|
|
|
Then test it works with:
|
|
|
|
```sh
|
|
swapon -va
|
|
```
|
|
|
|
Test other partitions in fstab with:
|
|
|
|
```sh
|
|
mount -a
|
|
```
