I just noticed this message in journalctl:
Aug 08 03:56:16 … kubelet[…]: I0808 03:56:16.967968 271557 warnings.go:110] "Warning: unknown field \"status.nodeInfo.swap\""
This may have started before my recent upgrade to 1.33. I haven’t been on k8s for long, maybe since 1.31? And I configured it to use swap, a recent feature at the time. In the EventList, I’m seeing:
"reason": "PossibleMemoryBackedVolumesOnDisk",
"message": "The tmpfs noswap option is not supported. Memory-backed volumes (e.g. secrets, emptyDirs, etc.) might be swapped to disk and should no longer be considered secure.",
Ideas?
