Previously, while upgrading from Red Hat Storage 2.0 to Red Hat Storage 2.1, new settings were only stored in smb.conf.rpmnew and were not applied. The new settings mentioned in smb.conf.rpmnew are critical and if they are not applied leads to poor performance of Red Hat Storage volume accessed using Samba. Now, all Red Hat Storage specific Samba settings are added to a secondary configuration file which will be automatically updated on every upgrade. This secondary configuration file overrides any settings that were defined in primary smb.conf file. With this update, upgrades will not require any manual intervention to do a manual merge of existing and new recommended settings for Samba every time a upgrade is done.
