|
||
| ## Highlights | ||
|
|
||
| This is a maintenance release to support Redis Enterprise Software version 7.2.4-105. | ||
|
|
||
| ## New in this release | ||
|
|
||
| ### Enhancements | ||
|
|
||
| - Added support for Redis Enterprise Software 7.2.4-105 (RED-113750) | ||
|
|
||
| ## Version changes | ||
|
|
||
| ### Breaking changes | ||
|
|
||
| The following changes included in this release affect the upgrade process. Please read carefully before upgrading to 7.2.4-12. | ||
|
|
||
| #### Upgrade operating system | ||
|
|
||
| {{<warning>}}If your databases use modules, you need to update all nodes in the cluster to Redis Enterprise 7.2.4 or later before upgrading your operating system. See [Upgrade a cluster's operating system]({{<relref "/rs/installing-upgrading/upgrading/upgrade-os">}})in the Redis Enterprise Software documentation for more details.{{</warning>}} | ||
|
|
||
| #### terminationGracePeriodSeconds | ||
|
|
||
| The configurable `terminationGracePeriodSeconds` REC field has been added to replace the hard-coded timeout of 15 minutes for a node to be stopped/drained (RED-111471). | ||
|
|
||
| #### ValidatingWebhookConfiguration | ||
|
|
||
| Versions 6.4.2-4 and later include a new `ValidatingWebhookConfiguration` resource to replace the `redb-admission` webhook resource. To use releases 6.4.2-4 or later, delete the old webhook resource and apply the new file. See [upgrade Redis cluster]({{<relref "/kubernetes/upgrade/upgrade-redis-cluster#reapply-webhook">}}) for instructions. | ||
|
|
||
| #### OpenShift SCC | ||
|
|
||
| Versions 6.4.2-6 and later include a new SCC (`redis-enterprise-scc-v2`) that you need to bind to your service account before upgrading. OpenShift clusters running version 6.2.12 or earlier upgrading to version 6.2.18 or later might get stuck if you skip this step. See [upgrade a Redis Enterprise cluster (REC)]({{<relref "/kubernetes/upgrade/upgrade-redis-cluster#before-upgrading">}}) for instructions. | ||
|
|
||
| ### Upcoming changes | ||
|
|
||
| - A future release of Redis Enterprise will remove support for RHEL7. We recommend migrating to RHEL8. | ||
|
|
||

||
| ## Known limitations | ||
|
|
||
| The limitations below are specific to the Redis Enterprise for Kubernetes product. To view limitations for the supported Redis Enterprise Software version, see the [7.2.4 release notes]({{<relref "/rs/release-notes/rs-7-2-4-releases#known-limitations">}}). | ||
|
|
||
| ### Existing limitations | ||
|
|
||
| - **When modifying the database suffix for an Active-Active database, while the service-rigger is in a terminating state, the services-rigger will delete and create the ingress or route resources in a loop (RED-107687)** Wait until the services- rigger pod has finished to terminate it. | ||
|
|
||
| - **REAADB changes might fail with "gateway timeout" errors, mostly on OpenShift (RED-103048)** Retry the operation. | ||
|
|
||
|
|
||
| - **Creating two databases with the same name directly on Redis Enterprise software will cause the service to be deleted and the database will not be available (RED-99997)** Avoid duplicating database names. Database creation via K8s has validation in place to prevent this. | ||
|
|
||
| - **Installing the operator bundle produces warning: `Warning: would violate PodSecurity "restricted: v1.24"` (RED-97381)** Ignore the warning. This issue is documented as benign on official Red Hat documentation. | ||
|
|
||
| - **RERC resources must have a unique name (RED-96302)** The string "rec-name"/"rec-namespace" must be different from all other participating clusters in the Active-Active database. | ||
|
|
||
| - **Admission is not blocking REAADB with `shardCount` which exceeds license quota (RED-96301)** Fix the problems with the REAADB and reapply. | ||
|
|
||
| - **Active-Active controller only supports global database options. Configuration specific to location is not supported (RED-86490)** | ||
|
|
||
| - **Active-Active setup removal might keep services or routes undeleted (RED-77752)** Delete services or routes manually if you encounter this problem. | ||
|
|
||
| - **`autoUpgrade` set to `true` can cause unexpected bdb upgrades when `redisUpgradePolicy` is set to `true` (RED-72351)** Contact support if your deployment is impacted. | ||
|
|
||
| - **Following the previous quick start guide version causes issues with creating an REDB due to unrecognized memory field name (RED-69515)** The workaround is to use the newer (current) revision of Deploy Redis Enterprise Software for Kubernetes. | ||
|
|
||
| - **PVC size issues when using decimal value in spec (RED-62132)** Make sure you use integer values for the PVC size. | ||
|
|
||
| - **REC might report error states on initial startup (RED-61707)** There is no workaround at this time except to ignore the errors. | ||
|
|
||
| - **Hashicorp Vault integration - no support for Gesher (RED-55080)** There is no workaround for this issue. Gesher support has been deprecated. | ||
|
|
||
| - **REC clusters fail to start on Kubernetes clusters with unsynchronized clocks (RED-47254)** When REC clusters are deployed on Kubernetes clusters without synchronized clocks, the REC cluster does not start correctly. The fix is to use NTP to synchronize the underlying K8s nodes. | ||
|
|
||
| - **Deleting an OpenShift project with an REC deployed may hang (RED-47192)** When an REC cluster is deployed in a project (namespace) and has REDB resources, the REDB resources must be deleted first before the REC can be deleted. Therefore, until the REDB resources are deleted, the project deletion will hang. The fix is to delete the REDB resources first and the REC second. Then, you can delete the project. | ||
|
|
||
| - **Clusters must be named 'rec' in OLM-based deployments (RED-39825)** In OLM-deployed operators, the deployment of the cluster will fail if the name is not "rec". When the operator is deployed via the OLM, the security context constraints (scc) are bound to a specific service account name (namely, "rec"). The workaround is to name the cluster "rec". | ||
|
|
||
| - **Readiness probe incorrect on failures (RED-39300)** STS Readiness probe does not mark a node as "not ready" when running `rladmin status` on node failure. | ||
|
|
||
| - **Internal DNS and Kubernetes DNS may have conflicts (RED-37462)** DNS conflicts are possible between the cluster `mdns_server` and the K8s DNS. This only impacts DNS resolution from within cluster nodes for Kubernetes DNS names. | ||
|
|
||
| - **K8s-based 5.4.10 clusters seem to negatively affect existing 5.4.6 clusters (RED-37233)** Upgrade clusters to latest version. | ||
|
|
||
| - **Node CPU usage is reported instead of pod CPU usage (RED-36884)** In Kubernetes, the reported node CPU usage is the usage of the Kubernetes worker node hosting the REC pod. | ||
|
|
||
| - **An unreachable cluster has status running (RED-32805)** When a cluster is in an unreachable state, the state remains `running` instead of triggering an error. | ||
|
|
||
| - **Long cluster names cause routes to be rejected (RED-25871)** A cluster name longer than 20 characters will result in a rejected route configuration because the host part of the domain name exceeds 63 characters. The workaround is to limit the cluster name to 20 characters or fewer. | ||
|
|
||
| - **Cluster CR (REC) errors are not reported after invalid updates (RED-25542)** A cluster CR specification error is not reported if two or more invalid CR resources are updated in sequence. |
