Juniper - minor host 0 /var partition usage is high

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 ...

Nope. There is no multi-speed option in 1/10G optics for Juniper (or Cisco or most others). That said, you can likely just put another 1GE SFP optic into the SFP+ slot currently occupied by the 10G ...
