It’s been about a day since this issue and now I’ve been keeping a close eye on my local-lvm, it fills fast, like, ridiculously fast and I’ve been having to run sudo fstrim / inside the VM just to keep it maintained. I’m finding it weird I’m now just noticing this as this server has been running for months!

For now I edited my /etc/bash.bashrc so whenever I ssh in it’ll automatically run sudo fstrim /, there is something I’m likely missing but this works as a temporary solution.
