So, without really thinking too much, I ran this script:
#!/bin/bash
SWAP="${1:-512}"
NEW="$[SWAP*1024]"; TEMP="${NEW//?/ }"; OLD="${TEMP:1}0"
sed "/^Swap\(Total\|Free\):/s,$OLD,$NEW," /proc/meminfo > /etc/fake_meminfo
mount --bind /etc/fake_meminfo /proc/meminfo
It worked really well for lying about my swap-space, but now I'd like good old commands like
free -m
to work again, but /proc/meminfo is totally empty and the server doesn't seem to know anything about it's RAM any more, even with atop or somesuch.
Thanks for reading.
umount /etc/fake_meminfo
?
