Fix lack of disk space on louvre:/
Closed, ResolvedPublic


The root filesystem on louvre became full last night between 4am and 5am.

Proposed fixes:

  • extend the filesystem. Only 20 GB are currently being used while 500 GB remain free on the vg-louvre volume group.
  • remove various pve-kernel packages and other Linux versions. Only one of them is obviously being used while at least 25 different ones use space on the root filesystem.

Running sudo apt-get purge 'pve-kernel-4.(9|13).*' will clean up (some of) the useless kernels.

Proxmox ships /etc/apt/apt.conf.d/75pveconf which tells apt never to autoremove old pve-kernel packages;

What they should really do is use the same hook as Debian, which generates a configuration file that prevents autoremoving only a few kernels (the latest one, the running one, and the version below the currently running one) and lets apt clean up the rest, but I guess they consider hypervisor disk space to be cheap...

The current situation looks good enough for now, closing.
