After HDD crash and reboot with spare disk, openVPN not working

[big_blue]

Hi.
After a HDD crash and boot with the valid drive all the openVPN connection are not working any more. I ve got a certificate validation error while open the tunnel and pfSense was not able to validate the user.

After reload a backup of the config everything was fine again.

Background:
During installation i created a ZFS mirror drive. So the two devices will be written in parallel. In my mind a failure of one disk is not a problem.

After changing the SATA connection of the valid disk i was able to boot pfSeense from this disk and all the config looks good.

After a while i getting a call, the VPN is not able to work any more. I do some tests and got the certificate validation error. I created a manual backup a few hours ago, and after reload the config from that backup everything was fine.

Now i am a little bit confused about the ZFS mirror while installation process. I expect both of the disk are the same and there is no difference which one of the HDDs i am using to boot and start the pfsense.

Is there something more i have to prepare to get a full backup lf the config on both HDDs?

Hmm, that's odd. Were you able to see the cert being passed? Why it was failing?

The drive mirror should have identical configs. I can only see that sort of error happening if it somehow pulled in some older config from somewhere. That would have been logged at boot if it had though.

That was my expectation too. I didn't notice anything during the boot process. I was in a hurry, so I didn't look carefully at the logs.

At the moment it is not a problem, the backup was only a few hours old. I just wanted to make sure that I didn't do anything wrong at the initial setup.
