How to mount a zfs disk on an installed FreeBSD system

My FreeBSD desktop had a system on an SSD disk, under the file washer used the HDD disk. All this was spinning on celerone with 512MB of RAM and of course on ufs.

Now there is 6GB of RAM and I, like many, probably wanted to see how the system would work on zfs, how much faster it would be, but that's not the point .

I installed FreeBSD on my SSD using the ZFS file system and mounted a ZFS formatted HDD with the pool already created. The system worked fine, but the trouble is, the second disk was not mounted.

If someone had a similar problem and the disk with the ZFS created zpool was not mounted on the installed system, then this article may be useful to you.

 

So run the command to see the mounted pools

 

zpool list

 

You will see only one pool

 

In my case

 

NAME SIZE ALLOC FREE EXPANDSZ FRAG CAP DEDUP HEALTH ALTROOT

zroot 81.5G 12.4G 69.1G - 11% 15% 1.00x ONLINE -

 

or

 

zpool status

 

to view the available pools for import, execute

 

zpool import

 

I first just imported zpool into the alternate root directory with the command to check if it mounts or not

 

zpool import -o altroot=/mnt name your pool

 

Yes, the pool was mounted in the /mnt directory, you can check the command

 

ls /mnt

 

When I made sure that everything ok exported zpool with the command

 

zpool export

 

after rebooting the system, the second disk was mounted, it needs to be mounted with the creation of a cache with the command

 

zpool import -o ro and here the name of your ZFS pool is

 

Done.
