Creating a boot environment from an existing one

Now, it's an appropriate time to talk about the possibility of creating a new environment from an existing one.

Getting ready

To follow this recipe, it's necessary that we have a machine (physical or virtual) running Oracle Solaris 11; we log in to the system as the root user and open a terminal. Some extra disk space might be necessary.

How to do it…

To perform this recipe, we're obliged to create a backup from the current BE (solaris_test_1), after which we should be successful in creating a new BE from this backup. The whole process uses snapshots. (In this case, we are using a logical snapshot, which uses pointers to leave the original image untouched.) Let's create a snapshot by running the following command:

root@solaris11:~# beadm create solaris_test_1@backup
root@solaris11:~# beadm list -a solaris_test_1
BE/Dataset/Snapshot                               Active Mountpoint Space   Policy Created          
-------------------                               ------ ---------- -----   ------ -------          
solaris_test_1
rpool/ROOT/solaris_test_1                         NR     /          26.06G static 2013-11-05 22:38 
rpool/ROOT/solaris_test_1/var                     -      /var       421.96M static 2013-11-08 04:06 
rpool/ROOT/solaris_test_1/var@2013-10-10-22:27:20 -      -          66.49M  static 2013-10-10 19:27 
rpool/ROOT/solaris_test_1/var@2013-11-08-06:06:01 -      -          62.48M  static 2013-11-08 04:06 
rpool/ROOT/solaris_test_1/var@backup              -      -          73.0K   static 2013-11-08 04:23 
rpool/ROOT/solaris_test_1/var@install             -      -          63.03M  static 2013-10-05 21:01 
rpool/ROOT/solaris_test_1@2013-10-10-22:27:20     -      -          132.81M static 2013-10-10 19:27 
rpool/ROOT/solaris_test_1@2013-11-08-06:06:01     -      -          65.78M  static 2013-11-08 04:06 
rpool/ROOT/solaris_test_1@backup                  -      -          0       static 2013-11-08 04:23 
rpool/ROOT/solaris_test_1@install                 -      -          105.95M static 2013-10-05 21:01

We are now ready to create a new BE from another one:

root@solaris11:~# beadm create -e solaris_test_1@backup solaris_test_2
root@solaris11:~# beadm list
BE                 Active Mountpoint Space   Policy  Created        
--                 ------ ---------- -----   ------  -------          
solaris            -      -          8.57M   static  2013-10-05 20:44 
solaris-backup-1   -      -          303.0K  static  2013-10-26 22:49 
solaris-backup-a   -      -          7.26G   static  2013-10-10 19:57 
solaris_test_1     NR     -          26.06G  static  2013-11-05 22:38 
solaris_test_2     -      -          209.0K  static  2013-11-08 04:23

At this point, it might be logical to activate this environment (beadm activate solaris_test_2) and boot it.

Finally, before finishing the chapter, we need to reactivate the original solaris boot environment, reboot the system, and remove all the remaining BEs:

root@solaris11:~# beadm activate solaris
root@solaris11:~# init 6
root@solaris11:~# beadm destroy solaris_test_2
Are you sure you want to destroy solaris_test_2?  This action cannot be undone(y/[n]): y

root@solaris11:~# beadm destroy solaris_test_1
Are you sure you want to destroy solaris_test_1?  This action cannot be undone(y/[n]): y

root@solaris11:~# beadm destroy solaris-backup-a
Are you sure you want to destroy solaris-backup-a?  This action cannot be undone(y/[n]): y

root@solaris11:~# beadm destroy solaris-backup-1
Are you sure you want to destroy solaris-backup-1?  This action cannot be undone(y/[n]): y

root@solaris11:~# beadm list
BE       Active  Mountpoint  Space   Policy  Created          
--       ------  ----------  -----   ------  -------          
solaris  NR      /           25.46G  static  2013-10-05 20:44

An overview of the recipe

This final recipe from the chapter has shown us a quick way to create a new BE based on an old one. To do this, we needed to take a backup first. Finally, we destroyed the existing BEs to clean up our system. Obviously, it's not appropriate to destroy the booted BE.
