Last Modified: May 29, 2024

Affected Product(s):
BIG-IP TMOS(all modules)

Known Affected Versions:
13.1.0, 13.1.0.1, 13.1.0.2, 13.1.0.3, 13.1.0.4, 13.1.0.5, 13.1.0.6, 13.1.0.7, 13.1.0.8, 13.1.1, 13.1.1.2, 13.1.1.3, 14.0.0, 14.0.0.1, 14.0.0.2, 14.0.0.3, 14.0.0.4, 14.1.0, 14.1.0.1, 14.1.0.2, 14.1.0.3, 14.1.0.5

Fixed In:

Opened: Oct 03, 2018

Severity: 3-Major

Symptoms

The /var partition might become completely full on the disk due to files being written to /var/config/rest. This condition may be accompanied by console error messages similar to the following: 011d0004:3: Disk partition /var (slot #) has only 0% free Additionally, there may be periodic restjavad and bigd daemons restarts related to disk space exhaustion.

Impact

The partition housing /var/config/rest may become 100% full, impacting future disk IO to the partition

Conditions

Process traffic while DoS Dashboard is open on multi-blade VIPRION systems.

Workaround

This workaround is temporary in nature, and may need to be periodically performed either manually or from a script. While these steps are performed, the BIG-IP REST API are temporarily inaccessible, and higher disk IO may be seen. Run the following commands, in sequence: bigstart stop restjavad rm -rf /var/config/rest/storage*.zip rm -rf /var/config/rest/*.tmp bigstart start restjavad Manual application of these workaround steps clears the 100% utilized space condition and allows the partition to resume normal operation.

Fix Information

The system deletes all Zip files in the REST root directory so that the partition-full condition no longer occurs.
