Re: [Users] Is this mkswap message from OpenVZ?
If your MySQL is dying because of lack of memory, this is a sign that you need to upgrade your RAM, adding at least 1GB more, not to add swap. I understand the economical aspect, but today the price per GB of RAM is cheaper than ever. If your provider is charging too much for your budget, and price is your first priority, you can find really cheap OpenVZ options here https://lowendbox.com/tag/openvz/ There are providers offering servers per year and others with 5GB RAM servers for $5/month.

A small swapfile would be most useful and economical for us. I think the lack of a swapfile and OOM kills are the worst choice because they create a DoS in practice.

By default, OpenVZ doesn't allow swap creation inside containers. And this is a good thing. It is not good to use storage to act as memory, since the performance is really bad. When needing more memory, just upgrade the hardware profile of your VM with your provider.

[Users] Is this mkswap message from OpenVZ?
Hi Everyone, I'm trying to track down the cause of the error message below. It is encountered when we try to enable a swapfile for a low-end VM. The VPS provider uses OpenVZ. # ./vm-swapfile.sh Swapfile already allocated swapon: /swapfile: swapon failed: Operation not permitted Failed to enable swapfile The relevant command is: if ! swapon /swapfile; then echo "Failed to enable swapfile" fi Is this mkswap message from OpenVZ?
