We need to mount zfs under mfsbsd to correct some scripts. zfs mount -a does nothing, zfs list the same. zpool shows two hard drives. Would be nice if someone could help me to solve this.
Regardless of the OS you are running, you need to import a pool then file systems inside it will be mounted automatically (unless specific configuration).
Run first zpool import to get the list of pools available on connected devices then zpool import poolname.
