Symptoms

Unable to see shares after a takeover.

Cause

After a takeover, the surviving storage controller can own more than one pool.

Solution

Ensure storage pool is imported by checking the storage controller head BUI:

configuration > storage > show

When BUI is started, pools can randomly pick the available pool.

Select the correct pool by going to the Shares > Pools tab (on the BUI under the Sun Oracle banner) and select the pool.

On the CLI > shares > set pool=<poolname>

Shares from the selected pool will then be displayed.

From https://<ZFS-SA-IP-Address>:215/wiki/index.php/Shares:Concepts

When multiple pools are active on a single host, the BUI will display a drop-down list in the menu bar that can be used to switch between pools.

In the CLI, the name of the current pool will be displayed in parenthesis, and can be changed by setting the 'pool' property.

If there is only a single pool configured, then these controls will be hidden.

When multiple pools are selected, the default pool chosen by the UI is arbitrary, so any scripted operation should be sure to set the pool name explicitly before manipulating any shares.
