I have an Amazon image with 1 root image, 1 image that I uses for websites and is only using 25%, and 1 image "unused"
So I thought... maybe I can use that unused image for a linux swap file.
Since I have 10 Gb (9.2G Avail) would it be wise to create a 8GB swap file on this Volume or would that not be best practice? (I run some WordPress sites only) (memory = 3.75GB)
Can I somehow tell "use the complete disk as swap space" instead of indicating the specific amount?
dd if=/dev/zero of=/mnt/web2/swapfile bs=1024 count=8388608
mkswap /mnt/web2/swapfile
swapon /mnt/web2/swapfile
and
[root@ip-* web2]# free -m
total used free shared buffers cached
Mem: 3754 3715 38 0 11 3517

[root@ip-* etc]# cat fstab
