QoreStor 6.1.0 - Release Notes

Upgrade notes

This topic contains important information for users who are upgrading from a previous QoreStor release.

  • During the upgrade, the QoreStor installation script will verify that the Repository and Metadata filesystems are mounted with the noatime and dirsync mount options. If not, the installation script will prompt the user to allow the script to make the necessary changes in /etc/fstab and prompt you to reboot the system and re-run the QoreStor installation process.

    NOTE: The above process does not occur when installing QoreStor in Demo mode.

  • To ensure proper authentication of network shares, after upgrading to QoreStor 6.1, remove the QoreStor server from the domain and re-add it to the domain.
  • QoreStor 6.1 contains support for VTL protocols. To enable VTL support, you must perform the following sequence of operations:
    • Upgrade your existing installation to QoreStor 6.1. Do not select the option to install VTL support at this point.
    • Using the steps documented in "Uninstalling QoreStor while maintaining configuration data" in the QoreStor Installation Guide, uninstall the newly updated QoreStor installation.

      IMPORTANT: Uninstalling your existing QoreStor with the command below will preserve your data and application configurations.

      /opt/qorestor/bin/qs_uninst

      When running this command, you will receive the prompt:

      To completely remove the application, user data, and configuration files, answer 'no' below,
      and rerun the uninstaller with the '-a' option.
      Do you wish to continue? yes\no [no]:

      Enter Yes to continue without removing your data.

    • Reinstall QoreStor 6.1 with VTL support by either using the --install-vtl option or answering “yes” to the prompt for adding VTL support.
  • When using QoreStor with VTL, upgrades to the operating system of the QoreStor server require additional configuration. Refer to "Upgrading the QoreStor Operating System" in the QoreStor Installation Guide.

Upgrading QoreStor instances on Microsoft Azure

For QoreStor instances running on Microsoft Azure, perform the actions below before upgrading to 6.1.

  • At the prompt, execute the following commands:
    curl -o azureclient.rpm https://rhui-1.microsoft.com/pulp/repos/microsoft-azure-rhel7/rhui-azure-rhel7-2.2-74.noarch.rpm
    sudo rpm -U azureclient.rpm
    sudo yum clean all

Upgrading a migrated DR Series appliance to QoreStor 6.1.0.840

If you have previously migrated your DR Series system to QoreStor, you must upgrade your QoreStor software to build 6.1.0.814 before upgrading to this build (6.1.0.840). The upgrade process in build 6.1.0.814 includes a step that flushes WAM data, and that process must be completed before upgrading to 6.1.0.840.

Upgrading to Rapid CIFS Plug-in 4.0.3.2 with Secure Connect

Secure Connect is comprised of a set of client and server components that create a resilient and secure communication channel for use by WAN-connected clients. The server components are installed and enabled by default during the installation of the QoreStor server. Starting with the Rapid CIFS plug-in version 4.0.3.2, the plug-in installer includes the option to install and enable Secure Connect.

IMPORTANT: Refer to the Known Issues section of this document for Rapid CIFS issues known to be present at the time of release.

If you have WAN-connected Rapid CIFS clients and choose to install Secure Connect, you can do so by following the steps below:

  1. On the media server, map a network share to your CIFS-enabled container.
  2. Download the plug-in installer from the website, as detailed previously.
  3. Open a command prompt with the “Run as Administrator” option selected. To do this using the Windows Start menu, click Start → All Programs → Accessories. Right-click Command Prompt and selectRun as Administrator.

    This gives all the required privileges to install/copy the driver files to the Windows drivers folder.

  4. Run QuestRapidCIFS-4.0.3233.1.exe.
  5. When prompted, select Install a Secure Connection to install Secure Connect.

    Secure Connect ensures backups to QoreStor are completed in spite of slow or unreliable WAN connections. When selecting this option, you will be prompted for additional configuration information required to make Secure Connect function correctly.

  6. At the Configure Secure Connect page, complete the dialog using the IP or fully qualified domain name (FQDN) of the QoreStor server and appropriate credentials.

    The user account used must have the CIFS role assigned.

    NOTE: The Configure Secure Connect operation is not supported for CIFS containers on DR Series appliances. DR Series appliances do not contain the required Secure Connect server component . This operation is available only for QoreStor instances. For CIFS containers on DR Series appliances, connect using the Rapid CIFS plug-in and the DR Series host name.

    NOTE: The value entered in the Display Name field must not match the hostname of the QoreStor server.

Upgrading to Rapid NFS Plug-in 4.0.3.3

Secure Connect is comprised of a set of client and server components that create a resilient and secure communication channel for use by WAN-connected clients. The server components are installed and enabled by default during the installation of the QoreStor server. Starting with the Rapid NFS plug-in version 4.0.3.3, the plug-in installation script includes the option to install and enable Secure Connect.

IMPORTANT: This new plug-in supports:

  • RHEL Linux and CentOS Linux 6 (when not using Secure Connect)
  • RHEL Linux and CentOS Linux 7
  • RHEL Linux and CentOS Linux 8
  • SLES 11 (when not using Secure Connect)
  • SLES 12
  • SLES 15

If you have WAN-connected Rapid NFS clients and choose to install Secure Connect, you can do so by following the steps below:

  1. Download QuestRapidNFS-4.03310.0-x86_64.bin.gz from the website.
  2. Unzip the package.
    unzip QuestRapidNFS-4.03310.0-x86_64.bin.gz
  3. Assign execute bit to change the permission of the binary package:
    chmod +x QuestRapidNFS-4.03310.0-x86_64.bin
  4. Install the Rapid NFS package. Before installing, remove the stale NFS entry.
    QuestRapidNFS-4.03310.0-x86_64.bin -install
  5. Load the file system in user space (FUSE) module, if not already loaded:
    modprobe fuse 
    
  6. Create a directory on the client. For example:
    mkdir /mnt/backup
  7. Mount Rapid NFS as a file system type using the mount command. For example:
     mount -t rdnfs 10.0.0.1:/containers/backup/mnt/backup -o sc,user=backup_user,password=<backup_user password>

    If you do not wish to type the password in plan text do not include the “password” option and you will be prompted:

    mount -t rdnfs 10.0.0.1:/containers/backup /mnt/backup -o sc,user=backup_user
    Password:
     

    If you are using a DMA that supports a marker, set the marker by using -o in the mount command. For example, if you wanted to set the CommVault marker (cv):

    mount -t rdnfs 10.0.0.1:/containers/backup /mnt/backup -o marker=cv
     

    It is also possible to use fstab entriest without the password option, this will prompt for the password the first time but will use the password hash for future mounts. With this it is possible to mount on boot without interrupting boot or prompting for a password:

    10.0.0.1:/containers/backup   /mnt/backup   rdnfs   sc,user=backup_user,marker=cv,defaults,soft,netdev,intr  0  0

    NOTE: If you want to do a mount on AIX, you must set the nfs_use_reserved_ports and portcheck parameters first. The parameters cannot be set to 0. For example: root@aixhost1 / # nfso -po portcheck=1 root@aixhost1 / # nfso -po nfs_use_reserved_ports=1

  8. To ensure that the NFS container has the insecure option set, execute the command below on the QoreStor server:
    /opt/qorestor/bin/connection --update --name nfs1 --type NFS --options rw,insecure

ID Issue

QS-437

QS-438

When using multiple NetVault Backup Servers to access the same QoreStor Server, use storage group, container, and user names unique to each NetVault Backup server to avoid accidental deletions.

QS-627

12345678

After deleting a container and storage group, immediately creating a new container with the same name may fail.

Workaround:

This failure occurs because the old container is still in a delete_pending stage. To proceed with creating a new container, wait until the old container has been completely deleted via the QoreStor Cleaner run.

QS-1420

When executing the QoreStor uninstallation script, the script will report and continue if illegal options are entered.

QS-1446

If the QoreStor partition is not set to automount, and the QoreStor server is rebooted, the system appears to be operational but shows 0 physical capacity.

QS-1588 When running Optimized Duplication jobs in Backup Exec, the container quota is not enforced as it is for backup jobs.
QS-1670 For Linux clients, the full version number of RDA plug-ins is not displayed.

QS-1823

In some situations, the deduplication savings for a storage group shows as 100% before a backup has occurred.  Once a backup has occurred, the deduplication savings will be displayed accurately.

QS-1980

When deleting a storage group, the Storage Group page will display timestamp data where the storage group entry used to appear. This occurs because the storage group is still in a delete_pending stage. Once the delete is completed and the UI refreshes, the timestamp will not longer appear.

QS-2236

When installing QoreStor, if a required port is unavailable the installation will continue and be considered successful, yet QoreStor will start in Maintenance Mode.

Workaround:

Ensure that all required ports are available to QoreStor.

QS-2242

When installing QoreStor, the filesystem selected for the QoreStor repository should not contain data from other application or users. QoreStor must have exclusive access to the repository filesystem.

QS-2604

If unregistered clients access QoreStor CIFS shares by mounting the share, the /var/log/messages will contain numerous host name/mismatch errors.

Workaround:

Unregistered clients need to be updated in DNS server manually.

QS-2694

When the system time on the QoreStor server is synchronized with the domain time, this may cause the system time to adjust backwards. If this occurs, system statistics (like read/write throughput statistics) will appear to be hung for an amount of time equal to the time adjustment.

QS-3779

When using Secure Connect with NetVault Backup in a multiple-machine configuration (NetVault server, NetVault client, QoreStor server), Secure Connect can respond to errors only for connections between the NetVault server and QoreStor or the NetVault client and QoreStor. Secure Connect does not address connections between the NetVault server and NetVault client.

QS-4169

When using the Linux exports http_proxy or https_proxy, no_proxy is also required for the watcher service to function correctly. Refer to "Accessing QoreStor" in the QoreStor User Guide.

QS-5105 Changes to a Cloud Tier Policy for inclusions or exclusions will not take effect until the QoreStor service has been restarted.
QS-5438 After performing a DR to QoreStor migration, network settings are reset to default.
QS-5627 The current error output of "rda --limit" without any argument incorrect suggests limits are enforced via Mbps (megabits per second) when the limit is actually in MBps (megabytes per second).
QS-5629

When configuring a custom graph, if you select a period for which there is no data, the graph will be blank and display "No Data Available"

QS-5826 When performing a DR to QoreStor migration, bonding modes and MTU settings are not
QS-5891 Rapid CIFS is not supported on Windows Server 2016 with secure boot enabled.
QS-6291

When using the latest version of the Rapid CIFS plug-in with Veeam Backup and Recovery, the configurations below are required:

  • For the Backup Repository, change the Gateway Server option to The following server and enter the IP or hostname of the local machine.
  • For VMware Backup, the Gateway server should be changed from the Automatic selection to the Use the selected backup proxy servers only.
QS-6653

OST MSI plugin reports a new version is already installed when installing an updated driver

Workaround:

Uninstall the OST driver before installing the newer driver

QS-6662

Replication add for AIR should fail if replication_traffic and encryption options used in the --add CLI.

Both replication_traffic and encryption options are irrelevant to AIR and user should not be allowed to use them while adding AIR replication.

Above parameters are restricted in --update CLI so similarly should be blocked in add CLI.

QS-6782 When installing Rapid CIFS on Windows 2008 R2, the installation deploys driver version 4.0.3207.1 , causing the version displayed by rcifsctl.exe driver -q to be different from the version in the Windows Programs and Features dialog. The functionality of Secure Connect is not changed.
QS-6803 Customers running QoreStor on a DR Series appliance must perform an intermediate upgrade to 6.1.0.814 before upgrading to 6.1.0.840.
QS-6808

When configuring Backup Exec with CIFS shares using the display name, the steps below must be followed:

  1. In the command prompt, change directpries to the path C:\Program Files\Quest\Rapid CIFS.
  2. Execute rdcifsctl.exe sc -d for disable a secure connection.
  3. Configure storage in Backup Exec by specifying \\displayname\container as network share. During this configuration all connections from Backup Exec to QoreStor are secured.
  4. Execute rdcifsctl.exe sc -e to enable a secure connection.
QS-6860 During upgrade, the SMB config file is overwritten. Any manual changes to this file will be lost on upgrade.
QS-7029 When using Rapid NFS with Secure Connect, the NFS container must have insecure option set. This must be done via the command line. Refer to Upgrade notesfor more information.

Product Licensing

QoreStor offers a backend capacity licensing model to allow for simple integration with other Quest Data Protection products.

  • Standalone license - QoreStor is licensed by the amount of backend capacity required. Standalone licenses are available as either perpetual licenses (with no expiration), or term licenses, which expire after a specified period of time.
  • NOTE: Term licenses are intended for specific customer use cases, i.e., licensing according to yearly billing cycles. A perpetual license is appropriate for most customers.

QoreStor licenses are additive, meaning that if you purchase a 5TB license now, and a 10TB license in the future, you will have 15TB total capacity.

NOTE: Licenses for QoreStor are specific to the QoreStor server. When installing a license, the System ID for your QoreStor server is required. You can obtain the System ID with the command system --show | grep "System ID"

Evaluating QoreStor

QoreStor offers two methods for evaluation:

  • Default installation - If no license is installed, QoreStor defaults to a no-cost, 1TB capacity installation supported by the QoreStor Community. This option requires no license and does not expire.
    • If a license is applied to a server running in this mode, the free 1TB is not added to the purchased license capacity.
    • When installed in Demo mode, the capacity is limited to 100GB.
  • Full capacity trial - available on the Quest Software Trial site, which provides a 30-day evaluation license for up to 360TB and access to Quest Support. After the evaluation period has expired, the QoreStor server will operate in Manual Intervention mode until a license is applied. To use QoreStor beyond that time frame, you will need to purchase a perpetual standalone license.
    • If installed in Demo mode, the capacity is limited to 100GB
    • If a longer trial period is required, please contact Quest Sales.

If you have purchased a standalone license, you can install it using the system --license command, as described in the QoreStor Command Line Reference Guide.

NOTE: When ordering a license, the System ID for your QoreStor server is required. You can obtain the System ID with the command system --show | grep "System ID"
