System storage usage

General questions
1

Hello

I have run a system storage usage command and got the following:

Filesystem Size Used Avail Use% Mounted on
overlayfs 7.3G 7.2G 0 100% /
tmpfs 1.9G 0 1.9G 0% /lib/init/rw
udev 1.9G 316K 1.9G 1% /dev
tmpfs 1.9G 4.0K 1.9G 1% /dev/shm
/dev/sda1 7.3G 7.2G 0 100% /live/image
/dev/sda1 7.3G 7.2G 0 100% /live/cow
tmpfs 1.9G 0 1.9G 0% /live
tmpfs 1.9G 40K 1.9G 1% /tmp
/dev/sda1 7.3G 7.2G 0 100% /opt/vyatta/etc/config
tmpfs 1.9G 68K 1.9G 1% /var/run
none 1.9G 408K 1.9G 1% /opt/vyatta/config

I am very new to vyos, so the basic questions are:

  1. Is this machine n the verge of stop operating/shutting down?
  2. Which areas could I do some pruning, and which version of unix do I need to be familiar with?
2

show system image

and

delete system image imagename

Unless you’ve added a bunch of stuff, that’s honestly probably about the only place you can do pruning.

Thank you so much for the info.
