PRVF-7573: Sufficient swap size is not available on node "string"

Quick fix

Cause
Swap is smaller than the installer expects for the amount of RAM (for 1–16 GB of RAM, swap equal to RAM).
Fix
Add a swap file or partition on each node, or ignore the check in a lab environment.
dd if=/dev/zero of=/swapfile bs=1M count=8192
chmod 600 /swapfile && mkswap /swapfile && swapon /swapfile
echo '/swapfile swap swap defaults 0 0' >> /etc/fstab
