Symptoms

Before the upgrade of the ZFSSA array to the ak8.7.x appliance code version:

The graphical BUI and CLI once showed a value called "Free" under the data zpool in the main dashboard.

24.1TData
18.0TUsed
6.07TAvailable
(10.1T Free) <<<<< This value >>>>

After the upgrade of the zfssa array to the ak8.7.x code version this parameter is missing - all other parameters are there.

Changes

Array is upgraded to the ak8.7.x code version.

Cause

The change to remove the "free" parameter was made as per bug 22590437:

BUG 22590437 - Inconsistent size reporting in AK CLI and BUI

Solution

So as per the bug, the information was changed around as pre ak8.7.x

the "free" parameter actually showed the real available information

and the "avail" parameter showed the real free information.

Now the bug corrected the "avail" parameter to show the actual real available information.

The "free" parameter is still available - you can select the pool under status storage and do a get free but now that information will be the same as the "avail" parameter.
