Hi everyone,
I'm trying to make many LXc runn together and each of thoses CT has at least 2Go of SWAP
Yet during the install, the host has been set up with only 4Go of RAM and of course, many OOM killed the process that are put in SWAP CT.
I would like to increase the size of the SWAP dynamically. I know tht it is supposed to be easy, I found those ressources :
* http://www.jamescoyle.net/how-to/622-proxmox-openvz-swap-and-performance => Failed on the swapon
* https://www.cyberciti.biz/faq/linux-add-a-swap-file-howto/#comment-81591 this one failed with holes in the file
* fallocate failed while following this https://www.jamescoyle.net/how-to/1994-script-to-create-a-swapfile-on-linux
I tried with /dev/zero of /dev/random or /dev/urandom and also tried with small files and it still failing.
here is my conf :
Here is also the result of my swap conf:
My question is how to increase the swap?
Any help would be appreciated.
regards
