Patching cluster members

When an appliance update is released, apply the patch so all appliances in the cluster are on the same version. See About cluster patching for more information on how Safeguard for Privileged Passwords handles access requests and system failures during the cluster patching process.

Prior to installing an update patch to a cluster

  • Ensure all appliances in the cluster are online and healthy. Any warnings or problems should be addressed before cluster patching. The patch install process will fail if any of the cluster members are unhealthy or cannot be contacted.

    IMPORTANT: The primary appliance orchestrates the cluster upgrade; therefore, the primary appliance must stay online and have a solid network connection with all of the replica appliances in the cluster. If this cannot be reasonably assured, you should unjoin the replica appliances from the cluster, individually upgrade them, and then re-enroll them into cluster.

  • It is highly recommended to take a backup of your primary appliance before applying a patch. For more information, see Backup and Restore.
  • You may want to unjoin a replica from the cluster to serve as a backup appliance. In case of a catastrophic failure, you can activate the unjoined replica to be the primary. If the cluster patching process is successful, upgrade the unjoined replica, and then re-enroll it back into the cluster.

To patch appliances in a cluster

  1. Log in to the primary appliance, as an Appliance Administrator.
  2. Go to the patch updates page:
    • web client: Navigate to Appliance > Patch Updates.

  3. Click Upload a File and browse to select an update file.

    The patch will be uploaded and distributed to all of the appliances in the cluster.

    NOTE: If you make changes to the cluster, such as adding a new replica, while a patch is staged, the update file must be distributed to the new cluster member before the patch install process can begin. Safeguard for Privileged Passwords will not allow the patch install process to begin until all of the cluster members report that they have the update file stored locally.

    NOTE: Clicking the Cancel button during the distribution process stops the distribution of the update file to the replicas. At this point, you can click one of the following buttons:

    • Remove to remove the update file from all of the appliances in the cluster.
    • Distribute to Cluster to continue distributing the update file to each replica in the cluster.

  4. Once the file has been successfully distributed to all of the replicas in the cluster, click the Install Now button.

    The primary appliance will go into Maintenance mode to begin the update operation. Once the primary appliance is successfully updated, Safeguard for Privileged Passwords will perform the update operation on each replica, one at a time. During an update operation, the cluster will be locked so that no other cluster operations can interfere with the update operation. Once the update operation is completed on all cluster members, the cluster will automatically unlock so normal operations can resume.

    The Cluster view shows that an update operation is in progress and the cluster members that are locked, awaiting to install the update file. Go to:

    • web client: Navigate to Cluster > Cluster Management.

    In addition, go to Patch Updates:

    • web client: Navigate to Appliance > Patch Updates.

About cluster patching

The following information provides insight into how Safeguard for Privileged Passwords processes access requests during the cluster patching process. It also describes what happens if a cluster member loses power or network connectivity during the patching process.

Service guarantees

During a cluster upgrade, the cluster is split logically into the current version (side A) and the upgrade version (side B). Access request workflow is only enabled on one side at a time. Audit logs run on both sides and merge when the cluster patch completes. Initially, access request workflow is only enabled on side A, and replicas in PatchPending state can perform access requests. As appliances upgrade and move to side B, the access workflow migrates to side B when side B has a majority of the appliances. At this point in the upgrade process, replicas in PatchPending state can no longer perform access requests; however, all of the upgraded cluster members can perform access requests. There is a small window where access request workflow is unavailable as the data migrates from one side to the other.

Failure scenarios

If the primary appliance loses power or loses network connectivity during the upgrade process, it will try to resume the upgrade on restart.

If a replica is disconnected or loses power during an upgrade process, the replica will most likely go into quarantine mode. The primary appliance will skip that appliance and remove it from the cluster. This replica will need to be reset, upgraded, and then re-enrolled into the cluster manually to recover.

Configuration for password and SSH key check out

The policy may be configured such that a password or SSH key reset is required before the password or SSH key can be checked out again. If that is the case, the following can be temporarily configured prior to cluster patching and access request to allow for password or SSH key check out when a password or SSH key has not been reset.

  • The policy can be set to allow multiple accesses.
  • The policy can be set to not require a password or SSH key change at check in.
  • Emergency requests can be allowed so the user does not have to wait for the password or SSH key to be reset.

Using a backup to restore a clustered appliance

In a clustered environment, the objective of a cluster backup is to preserve and allow the restoration of all operational data, including access request workflow, users/accounts, audit logs, and so on. All appliances in a cluster (primary and replicas) can be backed up. However, a backup should only be restored to an appliance in the worst-case scenario where no appliance can be restored using the failover operation.

When a backup is restored to an appliance, the restore on the primary clears the primary's cluster configuration but does not change the replicas' cluster configuration. To avoid issues:

  1. If possible, unjoin the replicas from the cluster prior to a backup restore.

  2. If the primary has been set to encrypt the cluster backups with a password or GPG key, you must have the password or GPG private key to complete the upload and restore operation. For more information, see Backup protection settings.

  3. Upload and restore the backup on the appliance that will be the primary.
  4. If you did not unjoin the replicas prior to the backup restore, perform a cluster reset on each replica so they become standalones then join the replicas back into the cluster.

The appliance is restored as a stand-alone primary appliance in Read-only mode with no replicas. However, all the access request workflow, user/account, and audit log data that existed when the backup was taken is retained. This primary appliance can then be activated and replicas can be joined to recreate a cluster.

To take a backup of a physical appliance

  1. Log in to the appliance as an Appliance Administrator.
  2. Go to Safeguard Backup and Restore:
    • web client: Navigate to Backup and Retention > Safeguard Backup and Restore.

  3. As needed, you can run a backup, set a schedule for the backup, and encrypt the backup for a cluster from the primary. For more information, see Backup and Restore.

To restore a physical appliance from a backup

An Appliance Administrator can restore backups as far back as Safeguard for Privileged Passwords version 6.0.0.12276. Only the data is restored; the running version is not changed.

You cannot restore a backup from a version newer than the one running on the appliance. The restore will fail and a message like the following displays: Restore failed because backup version [version] is newer then the one currently running [version].

The backup version and the running version display in the Activity Center logs that are generated when Safeguard starts, completes, or fails a restore.

NOTE: If you want to use a backup file taken on a different appliance, that backup file must first be downloaded on the appliance where the backup was taken. The downloaded backup file will then need to be uploaded to the appliance that wants to use it before you can use the Restore option.

  1. Log in to the appliance to be restored as an Appliance Administrator.
  2. Go to Safeguard Backup and Restore:
    • web client: Navigate to Backup and Retention > Safeguard Backup and Restore.

  3. Select the backup to be used and click Restore. If a problematic condition is detected, Warning for Restore of Backup displays along with details in the Restore Warnings, Warning X of X message. Click Cancel to stop the restore process and address the warning or click Continue to move to the next warning (if any) or complete the process.

  4. If the backup is protected by a password, the Protected Backup Password dialog displays. Type in the password in the Enter Backup Password text box. For more information, see Backup protection settings.

  5. When the Restore dialog displays, enter the word Restore and click OK. For more information, see Restore a backup.

The appliance is restored as a stand-alone primary appliance in Read-only mode with no replicas.

To rebuild a cluster

  1. Log in to the primary appliance as an Appliance Administrator.
  2. Activate the Read-only primary appliance.
    1. Go to Cluster Management:
      • web client: Navigate to Cluster > Cluster Management.
    2. Select the node to be activated from the cluster view (left pane).
    3. Click Activate.

    4. Confirm the activate operation.

    For more information, see Activating a read-only appliance.

  3. One at a time, enroll the replica appliances to rebuild your cluster.
    1. Go to Cluster Management:
      • web client: Navigate to Cluster > Cluster Management.

    2. Click Add Replica to join a replica appliance to the cluster.

    Once the enroll operation completes, repeat to add your appliances back into the cluster as replicas.

    NOTE: Enrolling a replica can take up to 24 hours depending on the amount of data to be replicated and your network.

    For more information, see Enrolling replicas into a cluster.

Resetting a cluster that has lost consensus

Resetting the cluster configuration allows you to recover a cluster that has lost consensus. If the cluster regains consensus after connectivity is restored, the primary will return to Read-Write mode and password and SSH key check and change will be reenabled. However, if it does not regain consensus, the Appliance Administrator must perform a cluster reset to force-remove nodes from the cluster.

If you are concerned about network issues, reset the cluster with only the new primary appliance. Once the cluster reset operation is complete, enroll appliances one by one to create a new cluster.

 Caution: Resetting a cluster should be your last resort. It is recommended that you restore from a backup rather than reset a cluster.
Cautions

To avoid issues, consider the following cautions.

  • Only reset the cluster if you are certain that consensus has been lost; otherwise, you could introduce a split-brain scenario. (Split-brain scenario is where a cluster gets divided into smaller clusters. Each of these smaller clusters believes it is the only active cluster and may then access the same data which could lead to data corruption.)
  • Ensure that no cluster member has Offline Workflow Mode enabled. For more information, see Offline Workflow (automatic).

To reset a cluster

  1. Go to Cluster:
    • web client: Navigate to Cluster > Cluster Management.

  2. Click the Reset Cluster button.

    The Reset Cluster dialog displays, listing the appliances (primary and replicas) in the cluster.

  3. In the Reset Cluster dialog, select the nodes to be included in the reset operation and use the Set Primary button to designate the primary appliance in the cluster.

    NOTE: Nodes must have an appliance state of Online or Online Read-only and be able to communicate to be included in the reset operation. If you select a node that is not online or not available, you will get an error and the reset operation will fail.

  4. Click Reset Cluster.

  5. In the confirmation dialog, enter the words Reset Cluster and click OK.

    When connected to the new primary appliance, the Configuring Safeguard for Privileged Passwords Appliance progress page displays, showing the steps being performed as part of the maintenance task to reset the cluster.

  6. Once the maintenance tasks have completed, click Restart.
  7. If an appliance is cluster reset as a standalone appliance, it will be placed in StandaloneReadonly mode (not online) and will require activation to avoid a split-brain scenario. For more information, see Activating a read-only appliance.

Once reset, the cluster only contains the appliances that were included in the reset operation.
