I have a bit of an odd question here. My pfSense machine died. I want to try to get the latest configuration file from it. It is formatted ZFS. I was thinking I could mount it in my Truenas server. Could someone please provide some guidance. TIA
Other Linux distros have ZFS as well, including Ubuntu, and they can be use easier than TrueNAS.
You should be able to connect the drive and from the TrueNAS command line run zfs import. That will fail, but it will give you the name of any pools available for import (and probably warn you that the pfSense pool was last used on another machine).
Running zfs import -f originalname pfsensepool will import the pool and rename it (worth doing just in case you have another pool of the same name already). You may have to use the altroot flag (i can’t remember what it is right now) because TrueNAS likes its zpools mounted under /mnt.
