The internal ZFSSA is used to provide iSCSI LUNS for the filesystems for the zones and IO domains. Default sizes may be insufficient for some customers and they may need to increase the size.

Note also that with the evolution of AK Software sine February 2018, which is bundled with the ZFSSA, best practice is to maintain a one to one relationship between LUNS and ZONES. In prior releases we had created a LUN and 'shared' it between zones. That practice is no longer recommended.

Purpose

This document explains how to increase the size of a ZFS pool - aka zpool - which has been created on an iSCSI LUN which is exported by the internal ZFSSA. The instructions in this document do not provide details on how to reduce the size of a zpool, as doing so can result in data loss.

Scope

The information in this document applies to Oracle SuperCluster. The instructions apply to zpools created or imported in both Application and Database Domains. Such zpools are created to install Solaris Zones and IO domains and the approach described in this document can be used to increase the storage space available to a zone.
