Adding datasets to running zones
Sometimes you need to have a new ZFS dataset in your zone because, you want to install a new application or a new instance of an application in it which needs some storage to work . Sometimes you just need it to dump a lot of data into a new dataset as some kind of ephemeral scratch space. Before Solaris 11.4 you needed to reboot your zone in order to add a new dataset. However with the newest iteration of the operating environment, you can do it live. With Solaris 11.4 you have Live Zone Reconfiguration for ZFS datasets.
An example
At first we obviously have to create a new ZFS dataset that we can add to a zone. The addition of the filesystem
The next commands add a new dataset to the zone configuration and add it to the running configuration.
Let’s check for the filesystem.
Right after the login, you won’t see the dataset. Just because you added it in the zone configuration doesn’t mean that it is ready to use. You have to import it first inside the zone.
Now it’s available for use. When you want to remove if from the zone, you have to export it first.
