ZFS over UFS and config restore

[BigFreddy]

Hi,

I have seen that ZFS offers snapshots feature as well as from my understanding doing research on this topic, ZFS requires slightly more RAM but is way less prone to corruption upon unexpected power loss. My question is about restoring the config file and I thought I would check just in case.

So, if you have a config file from the time when UFS was active but you restore it at the time when ZFS is active, it technically shouldn't cause any issues? I presume that the config file only contains configuration data related to the firewall and its settings and there is nothing in the config file about the file system that is currently used?

Thanks

No, none at all. The OPNsense configuration is not concerned with the underlying file system. There is even a bootstrap script turning a stock FreeBSD installation into an OPNsense - should you want to install on a RAIDZ2 topology or whatever ...

Thanks for confirming :)
