I tried searching but with the terms I used I couldn't find anything similar.
I'm running Ubuntu server in multiple VMs on my Proxmox machine. I frequently run into this issue on my VMs and I don't understand enough to figure out why...
When I make new VMs I usually use the default Proxmox disk size of 32 GB which I figure will be PLENTY for running some small docker apps. I install Ubuntu Server with defaults but on LVM. Somehow my VMs keep filling up though. I even have a VM right now running 18.04 that can't update because the / partition is full and there isn't anything running on the server. I installed plex for some testing but it has no library or anything.
So when I do a DF it shows that the root is only 3.9GB. For some reason there are 3 other partitions that look like temp, swap or something. My DF is pasted below. Is there a setting I need to change during install to stop so much of my disk from being wasted?
udev 7.9G 0 7.9G 0% /dev tmpfs 1.6G 9.0M 1.6G 1% /run /dev/mapper/ubuntu--vg-ubuntu--lv 3.9G 3.9G 0 100% / tmpfs 7.9G 4.0K 7.9G 1% /dev/shm tmpfs 5.0M 0 5.0M 0% /run/lock tmpfs 7.9G 0 7.9G 0% /sys/fs/cgroup /dev/loop0 90M 90M 0 100% /snap/core/7713 /dev/loop1 89M 89M 0 100% /snap/core/7396 /dev/vda2 976M 222M 688M 25% /boot tmpfs 1.6G 0 1.6G 0% /run/user/1000
Adding parted output. Disk shows as 43GB here because I was going to expand it.
