Protocols that are not required can be uninstalled from QoreStor by providing the required options to the uninstaller. QoreStor systems running software version less than 7.1.3, should first upgrade to 7.1.3 or higher to have the option available to uninstall the selective protocol stack from their QoreStor systems.
The uninstaller located at /opt/qorestor/bin/qs_uninst provides this option for selective removal of the protocol support. Execute following command to uninstall:

# ./qs_uninst –help
For example:
usage: qs_uninst [-a]

Use the following table to define the uninstall options:

Table 6: QoreStor uninstall protocol option definitions

Option	Definition
-a [optional]	complete removal of the application, data, metadata, and configuration
-h [optional]	print this help
--remove-cifs [optional]	remove support for CIFS
--remove-nfs [optional]	remove support for NFS
--remove-object-container [optional]	remove support for the object container service
--remove-vtl [optional]	remove support for VTL/NDMP/ISCSI
--remove-edm [optional]	remove support for Veeam EDM, and remove the qs_edmuser from the system

NOTE: Uninstaller checks for any existing containers of given protocol before proceeding with removal of those packages. RDS Containers used for CDP backups requires NFS protocol support for Instant Restore to succeed. Before Veeam EDM support can be removed from the QoreStor, the repository and the QoreStor server from the list of Linux servers should be removed from the Veeam Backup application.

Example Usage:

For removal CIFS protocol support
# /opt/qorestor/bin/qs_uninst --remove-cifs

For removal NFS protocol support
#/opt/qorestor/bin/qs_uninst --remove-nfs

For removal of support for the object container service
#/opt/qorestor/bin/qs_uninst --remove-object-container

To remove support for VTL/NDMP/ISCSI
#/opt/qorestor/bin/qs_uninst --remove-vtl
