Config.xml rollback after power interruption
Currently, I'm simulating a power interruption by pressing the reset button or unplugging the power on pfsense 2.5-RC. But, once the system boots up all your recent changes will be lost and pfsense will restore from previous config. I'm not sure where to check in the logs. Thanks.
That isn't normal, and is likely a side effect of what you are doing.
The filesystem is getting corrupted to the point where it can't read your config, so it restores a backup.
Filesystem corruption due to a power interruption like that is a known issue, though it isn't always that predictable or critical. Usually the automatic filesystem check is enough to fix it.
You can reinstall and use ZFS which should be more resilient against that kind of problem.
Thank you for your response. I also tried this on pfsense 2.4.5-p1 and I did not encountered the issue. But, reinstalling pfsense 2.5-RC using ZFS solved the issue. Thank you for your help.
