Hi Everyone,
I work with an open source project. We have a VM but it is low-end. The machine suffers OOM kills. We don't have access to /etc/fstab. Everything is an upsell with the VPS provider.
I'm trying to setup a swapfile during startup using Systemd but:
# swapon /swapfile swapon: /swapfile: swapon failed: Operation not permitted
This may be useful:
# command -v swapon /sbin/swapon # file /sbin/swapo swapoff swapon # file /sbin/swapon /sbin/swapon: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.32, BuildID[sha1]=a4891bc4dcfc533c61d76aa3e69870ab35d90c89, stripped
My question is, is there a way to sidestep the restriction? Is it possible to ask the kernel to use the swapfile without using the command?
You can try running for more details: # strace swapon /swapfile but the swap functionality is probably disabled in the kernel itself. -- Valentin
