Can you give output of 'show system disk-space' command to see utilization of all partitions.

No need to clean /opt/panlogs as this is where Palo keeps traffic and threat logs.

It will automatically delete older logs to avoid filling up that partition.

You can adjust how much logs to keep at 'Device > Setup > Management > Logging and Reporting Settings'

You can try to reboot firewall.

This often frees up some disk space.

Also upgrade to latest patch release as Palo often adds fixes to clear disk space.

For example another one in currently latest 11.1.x release.

PAN-274496
Fixed an issue where the root partition reached 100% which caused the system to become non-functional and fail over even when aggressive cleaning was enabled.
