In this week's Discussion of the Week, we're taking a look at a question about a filled up root partition and how to free up space. Let's take a look at common causes for the predicament and a few painless remedies. Community member scawsey13 poses the question in our discussion forum.
A couple of events can cause the root partition to slowly or rapidly fill up. In general, no service interruptions should result from the root partition being full, as it is not used for any operational storage. However, a full root partition can cause upgrades or certain packet captures to fail.
One common cause of a filled partition results when an admin is troubleshooting certain processes and creates core files. These files are stored on the root and remain there until deleted by the administrator.

/var/cores/: total 454M -rw-rw-rw- 1 root root 453M Feb 1 13:43 mgmtsrvr_7.0.3_0.tgz drwxrwxrwx 2 root root 4.0K Feb 1 13:43 crashinfo
/var/cores/crashinfo: total 0 -rw-r--r-- 1 root root 0 Feb 1 13:43 mgmtsrvr_7.0.3_0.info
These files can be exported using the scp or tftp export command, then deleted to free up space on the firewall:
