Currently running a EX4300 switch. We seem to be low on space on fpc0.

I have already run the request system storage cleanup all-members (only cleaned up a few megabytes).

I have cleared the WTMP file which cleared 20 - 30mb.

I am now looking to clear more space.

Ran the df -h command from the shell to give you an idea that the /var partition is currently sitting at 90% usage.

  • /var/tmp/ is really the only place you need to be concerned about day-to-day. Are you seeing some kind of issue? Sep 28, 2021 at 12:45

It looks like after taking the issue up with JTAC support, the /var partition was misrepresenting the amount of space that was actually in use. We haven't rebooted our switch in the last four years as it is our main core switch. As per JTAC, the reboot resolved the issue and the /var partition now reflects only 2% of the space is used.
