Create a new BE, based on the active BE.
Create a new BE, based on an inactive BE.
Create a snapshot of an existing BE.
Create a new BE, based on an existing snapshot.
Create a new BE, and copy it to a different zpool.
Activate an existing, inactive BE.
Mount a BE.
Unmount a BE.
Destroy a BE.
Destroy a snapshot of a BE.
Rename an existing, inactive BE.
Roll back a BE to an existing snapshot of a BE.
Display information about your snapshots and datasets.
Displays command usage.
Creates a new boot environment named beName. If the -e option is not provided, the new boot environment will be created as a clone of the currently running boot environment. If the -d option is provided then the description is also used as the title for the BE's entry in the GRUB menu for x86 systems or in the boot menu for SPARC systems. If the -d option is not provided, beName will be used as the title. -a
Activate the newly created BE upon creation. The default is to not activate the newly created BE.
Create a new BE with a description associated with it.
Create a new BE from an existing inactive BE.
Create a new BE from an existing snapshot of the BE named beName.
Create the datasets for new BE with specific ZFS properties. Multiple -o options can be specified. See zfs(1M) for more information on the -o option.
Create the new BE in the specified zpool. If this is not provided, the default behavior is to create the new BE in the same pool as as the origin BE.
Creates a snapshot of the existing BE named beName.
Destroys the boot environment named beName or destroys an existing snapshot of the boot environment named beName@snapshot. Destroying a boot environment will also destroy all snapshots of that boot environment. Use this command with caution. -f
Forcefully unmount the boot environment if it is currently mounted.
Force the action without prompting to verify the destruction of the boot environment.
Destroy all snapshots of the boot environment.
Lists information about the existing boot environment named beName, or lists information for all boot environments if beName is not provided. The 'Active' field indicates whether the boot environment is active now, represented by 'N'; active on reboot, represented by 'R'; or both, represented by 'NR'. Each line in the machine parasable output has the boot environment name as the first field. The 'Space' field is displayed in bytes and the 'Created' field is displayed in UTC format. The -H option used with no other options gives the boot environment's uuid in the second field. This field will be blank if the boot environment does not have a uuid. See the EXAMPLES section. -a
Lists all available information about the boot environment. This includes subordinate file systems and snapshots.
Lists information about all subordinate file systems belonging to the boot environment.
Lists information about the snapshots of the boot environment.
Do not list header information. Each field in the list information is separated by a semicolon.
Mounts a boot environment named beName at mountpoint. mountpoint must be an already existing empty directory.
Unmounts the boot environment named beName. -f
Forcefully unmount the boot environment even if its currently busy.
Renames the boot environment named beName to newBeName.
Roll back the boot environment named beName to existing snapshot of the boot environment named beName@snapshot.
Makes beName the active BE on next reboot.
The alternate BE location outside rpool/ROOT can be configured by modifying the BENAME_STARTS_WITH parameter in /etc/default/be. For example: BENAME_STARTS_WITH=rootfs
Example 1: Create a new BE named BE1, by cloning the current live BE.
# beadm create BE1
Example 2: Create a new BE named BE2, by cloning the existing inactive BE named BE1.
# beadm create -e BE1 BE2
Example 3: Create a snapshot named now of the existing BE named BE1.
# beadm create BE1@now
Example 4: Create a new BE named BE3, by cloning an existing snapshot of BE1.
# beadm create -e BE1@now BE3
Example 5: Create a new BE named BE4 based on the currently running BE. Create the new BE in rpool2.
# beadm create -p rpool2 BE4
Example 6: Create a new BE named BE5 based on the currently running BE. Create the new BE in rpool2, and create its datasets with compression turned on.
# beadm create -p rpool2 -o compression=on BE5
Example 7: Create a new BE named BE6 based on the currently running BE and provide a description for it.
# beadm create -d "BE6 used as test environment" BE6
Example 8: Activate an existing, inactive BE named BE3.
# beadm activate BE3
Example 9: Mount the BE named BE3 at /mnt.
# beadm mount BE3 /mnt
Example 10: Unmount the mounted BE named BE3.
# beadm unmount BE3
Example 11: Destroy the BE named BE3 without verification.
# beadm destroy -f BE3
Example 12: Destroy the snapshot named now of BE1.
# beadm destroy BE1@now
Example 13: Rename the existing, inactive BE named BE1 to BE3.
# beadm rename BE1 BE3
Example 14: Roll back the BE named BE1 to snapshot BE1@now.
# beadm rollback BE1 BE1@now
Example 15: List all existing boot environments.
# beadm list
