   Thanks for the training you gave me with this ZFS material.  I benefited from your creative web post, to use creating a ZFS install to Raspberry Pi 4B USB SSD  https://ghostbsd-arm64.blogspot.com/2022/09/freebsd-140-compiling-kernel-for.html  Fred's Blog post about installing FreeBSD 14.0-CURRENT onto a USB SSD drive using command 'bsdinstall'
https://linuxhint.com/mount-zfs-filesystems-in-different-directoris/ Great explanation and examples of creating a ZFS ZPOOL
commands:
zpool list
zpool import
zfs get mounted,canmount,mountpoint arm64pool
zfs set canmount=off arm64pool
zfs get canmount
 
 
1.)  Create an new unformated partition using FreeBSD command gpart
2.)  Create a pool from vdevs using the FreeBSD zpool create
3.)  Create ZFS filesystem directories in the pool
4.)  Install the files,   make installkernel
 
 

The following property can be set at creation time and import time:

Alternate root directory. If set, this directory is prepended to any mount points within the pool. This can be used when examining an unknown pool where the mount points cannot be trusted, or in an alternate boot environment, where the typical paths are not valid. altroot is not a persistent property. It is valid only while the system is up. Setting altroot defaults to using cachefile=none, though this may be overridden using an explicit setting.
 

The following properties can be set at creation time and import time, and later changed with the zpool set command:


=|pool[/dataset]
Identifies the default bootable dataset for the root pool. This property is expected to be set mainly by the installation and upgrade programs. Not all Linux distribution boot processes use the bootfs property.

zpool create -O compress=lz4 -O atime=off -o altroot=/arm64poolalt -m none arm64pool /dev/gpt/rootzfs

zpool import -R /mnt -N -f arm64pool 

reddit example:

zpool destroy zpi || true
zpool create -O compress=lz4 -O atime=off -o altroot=/zpialt -m none zpi da1s2
 

 Manipulating a pool from the rescue system

https://klarasystems.com/articles/manipulating-a-pool-from-the-rescue-system/ 

First, import the pool with an ‘altroot’ (a path prepended to all of the mountpoints, so as not to mount over top of the live system you are using). We also set the “do not automatically mount filesystems” flag, because we need to manually mount the boot environment.

# zpool import -R /mnt -N -f zroot

Once that completes, confirm you can see all of your datasets:

# mount -t zfs zroot/ROOT/default /mnt

If you are not sure what is currently the default boot environment, you can use:

# zpool get bootfs zroot

And it will return the name of the current default boot environment. Once you have mounted the root directory, you can mount the rest of the ZFS datasets:

# zfs mount -a

Now your broken system is mounted with a prefix of /mnt, so rc.conf will be in /mnt/etc/rc.conf, and you can edit files as required to repair your system.

Then just reboot without the USB/CD image connected, and your system should boot as normal.

Exporting a ZFS Storage Pool

To export a pool, use the zpool export command. For example:


# zpool export tank

The command attempts to unmount any mounted file systems within the pool before continuing. If any of the file systems fail to unmount, you can forcefully unmount them by using the -f option. For example:


# zpool export tank
cannot unmount '/export/home/eschrock': Device busy
# zpool export -f tank

After this command is executed, the pool tank is no longer visible on the system.

If devices are unavailable at the time of export, the devices cannot be identified as cleanly exported. If one of these devices is later attached to a system without any of the working devices, it appears as “potentially active.”

If ZFS volumes are in use in the pool, the pool cannot be exported, even with the -f option. To export a pool with a ZFS volume, first ensure that all consumers of the volume are no longer active.

Example of importing a zpool to an alternate mount point for servicing 

 zpool import -R /mnt -N -f arm64pool


root
Sets the cachefile property to none and the altroot property to root.
Import the pool without mounting any file systems.
 

Forces import, even if the pool appears to be potentially active.
 
arm64pool   is  the pool name
