Hello to everyone.
I've installed FreeBSD 13.1-RELEASE on a ZFS partition style on my ada0 disk. It is like this :
Now,I would like to mount the partition /dev/ada0p4 from FreeBSD because I need to modify a wrong entry that I have added to the /etc/fstab file on the /dev/ada0p4 partition (while now I'm using the FreeBSD system that I have installed on a UFS2 disk located at /dev/ada2) . This is what I did but I'm not able to import the zroot pool even if it says that the filesystem is already mounted,but I don't know where it is :
It says that it is already mounted,but I don't know where.
