Affected Product(s):
BIG-IP Install/Upgrade, LTM, TMOS
Known Affected Versions:
16.1.5, 16.1.5.1, 16.1.5.2, 16.1.6
Opened: May 29, 2025 Severity: 3-Major
Following a boot into a different software volume, occasionally csyncd on one or more secondary blades stops syncing most of the RRD files from the primary blade's /var/rrd/ directory to the local /var/rrd/ . The RRD files are used to generate the graphs in the BIG-IP GUI.
Some of the RRD files stop being synchronised from the primary blade to one or more of the secondary blades. After a primary blade ownership change, graphing data from the other blades (up to the point when the secondary blade became primary) is unavailable in the GUI and whenever a qkview is generated.
- Cluster running one of the affected versions. - Boot into a newly installed software volume, or into an already existing but different software volume. - Primary blade ownership change after the boot.
Restart the statsd daemon from the primary blade with: "bigstart restart statsd".
