      Hello, I have a pfSense box running on a VIA C3 and a 2GB Compact flash (embedded install), The system was running for around 26 days without any reboots. However, a couple of days ago I check to see how the box was doing and noticed the uptime changed to 2 days and data like RRD graphs was erased, configuration remained the same.

      My question: Does pfSense embedded erases all information like RRD graphs every month or is this an anomaly. Disk usage is 10%.

      Note: I checked on Google and re-read pfSense The Definitive Guide book before posting here.

      Any input is appreciated.

        If the system panics or power cycles you are likely to lose file system data.

        I can't comment on the specifics of RRD graph data in the embedded version, in particular how it deals with RRD data to minimise disk writes. I seem to recall seeing that the embedded version kept RRD data in a memory (RAM) file system and dumped it to "disk" from time to time but I don't recall whether that was just a proposal or something that was implemented. I don't recall any details about how often the data was (to be) dumped nor what version of pfSense that was relevant to.

          Embedded keeps RRD in RAM and by default only writes it to CF upon a normal shutdown. If you lose power, you lose RRD data. You can create a cron job to back it up periodically to make sure that doesn't happen if you lose power.

            You are both right, it seems that some one pulled the plug on the pfSense box without telling me. I am glad its not a hardware failure. Verified by pulling the plug on the system, all RRD info was erased.

            Thank you!.
