Some common symptoms of disk-space getting filled up are:
- Web interface not loading
- Certain daemons processes not starting
- Incomplete tech support bundles
- System log alerts with "Disk usage for / exceeds limit, X percent in use, cleaning file system"
- Unable to download PAN-OS software images or dynamic updates
- Any PAN-OS.
- Palo Alto Firewall.
The PAN-OS file system is divided into various directories. To view partitions and associated disk-space, use the command below:
> show system disk-space Filesystem Size Used Avail Use% Mounted on /dev/md2 3.8G 3.1G 581M 85% / << root partition /dev/md5 7.6G 4.2G 3.0G 59% /opt/pancfg . /dev/md6 3.8G 3.0G 666M 82% /opt/panrepo tmpfs 2.0G 210M 1.8G 11% /dev/shm cgroup_root 2.0G 0 2.0G 0% /cgroup /dev/md8 88G 2.4G 81G 3% /opt/panlogs tmpfs 12M 0 12M 0% /opt/pancfg/mgmt/lcaas/ssl/private
The PAN-OS file system has a default mechanism to rotate and clear disk-space. In some cases, manual intervention may be required to clear disk space.
