1.6.0 | Release Notes Upgrade Steps | - Add support for building cStor on ARM builds by moving cstor-pool-mgmt, cstor-volume-mgmt, maya-exporter and cspi-mgmt build scripts to their specific folders and add arm build scripts. - Add support for provisioning Local PV hostpath when the nodes are tainted. It also handles the implementation of Local PV helper pods where the cleanup pod will be launched with the tolerations. - Enhance the logging mechanism for cStor pool pods during pool import time. These changes of logs will help to identify the existence of bad disk on the node. - Support for enabling core dump by adding an ENV variable ENABLE_COREDUMP= “1” for cStor pool pod to control whether cores need to be dumped in case of process crashes. By default, dumping cores will be disabled. Make sure this environment variable is not enabled if mountPoint of SparseDir has been changed in CAS Templates.- Enhance upgrade logs by providing pool and volume status information during the upgrade and also helps in estimating the time taken for deployment pods to come up. - Improves Jiva rebuilding process by checkpointing the io numbers. Now only those snapshots will be synced which has less no of io’s. - Fixes an issue with Jiva controller by removing WO replica if new replica with greater revision count get added to controller. - Disable core dump in NDM daemon by default. This can be enabled by setting an ENV variable ENABLE_COREDUMP to 1. Core files will be stored inside /var/openebs/ndm/core.- Fixes issues in default core dumping location for NDM. System core pattern which is common for all processes on the node will not be modified. NDM will dump the cores in a location under openebs base directory. NDM process will be launched from the openebs directory, so core files will get automatically written to the $PWD, without requiring to change the core pattern. - Fixes an issue in NDM which caused cleanup pods not being scheduled on nodes with taints, causing BD to be stuck in release state. The fix will add tolerations for the node taints to the cleanup pod. - Fixes an issue in cstor-velero plugin for getting the StorageClass name from the annotation if StorageClass is mentioned in PVC Annotation, not in PVC spec.- Fixes an issue while cloning an filesystem based cStor volume, get the FStype info from the CAS config instead of using the default ext4 FSType. - Fixes an issue during upgrade where image tag contains multiple “:”. This usually happens where the proxy image URL is used which can contain multiple “:”. Alpha Features - Adding support to have the ZFS Local PV Provisioner in HA mode. Default replica count is set 1 and by changing the replica count will enable a new Provisioner pod with anti-affinity so that no two pods get scheduled on the same node. - Adding volume metric information for ZFS Local PV. These metrics can be collected using Prometheus. - Add support for configuring volume policies such as tolerations, nodeSelector , priorityClass, resourceLimits for main and sidecar target pod containers of cStor CSI volume using CStorVolumePolicy resource. - Add metrics support for cStor CSI volume which can be pulled by Prometheus to show the metrics in k8s cluster. Available metrics are Total capacity, Used capacity and Available capacity in Bytes.- Add raw block volume support for cStor CSI volume to be attached as Raw Block Volume to pods. - Add support for performing CSPC general validation in admission server. Some of the checks are included based on scenarios like use of duplicate block devices, duplicate nodes, block device should not be claimed by other CSPC/third party, the capacity validations of replacing block devices etc. - Add support for new setting requests and limits to cStor pool pod sidecar containers via poolConfig. It will take default auxResource values if it is not specified in poolConfig for a particular pool. The default can be specified in spec.auxResources.requests and spec.auxResources.limits. These values will be applied for all the pool configuration mentioned in the CSPC spec. It is also possible to specify separate auxResource values to each pool separately by adding those details to the poolConfig for a particular pool.- Configure Jiva CSI Driver to listen to custom ports for metrics. - Add metrics support for Jiva CSI volume which can be pulled by Prometheus to show the metrics in k8s cluster. Available metrics are Total capacity, Used capacity and Available capacity in Bytes. |

NDM can now also be compiled in ARM architecture using manual steps. - Added support for provisioning CSI based volume using lease leader election API. - Support of running OpenEBS in Kubernetes 1.16 version. The k8s v1.16 release will stop serving the deprecated API versions in favour of newer and more stable API versions. - Support the addition of resource limit to cStor pool pod using with CSPC configuration. resource field on CSPC is used to pass resource limit and requests to cstor-pool container and auxResource field on CSPC is used to pass resource limit and requests to other 2 containers such as cstor-mgmt and m-exporter.- Enhanced backup capability of openebs-velero plugin by checking the status of Healthy cStor Volume Replica. In the previous version, a check was performed for healthy CVR during setup only. There might be some chances of cStor pod restart and CVR becomes degraded when we trigger the backup.- Enhanced CVC(cStor Volume Claim) CR by adding provisioning failure events while provisioning cStor volume using CSI provisioner. - Fixed a bug where cStor volume becoming read-only due to restart of cstor-volume-mgmt container alone in the target pod. - Fixed wrong status on CVR from Duplicate to Online. Duplicate state on CVR was blocking reconcile on the volume creation in ephemeral case. - Fixed a bug in cStor storage pool YAML. The livenessProbe command zfs set io.openebs:livenesstimestamp sets the value of io.openebs:livenesstimestamp to the current timestamp. In previous versions, this value was not set properly because of some shell quoting issues in the command.- Fixed a bug where Jiva volume running on CentOS 7 / RHEL in OpenShift cluster is going to read-only when the controller pod is restarted either due to node restart or upgrades or any other reason. This is due to iSCSI default timeout is replaced with 5 sec if multipath support is enabled on the node. |
1.2.0 | Release Notes Upgrade Steps | - CSI Driver for cStor Volumes (currently in Alpha) has added support for resizing and volume expansion feature. - The new version of cStor Schema has been introduced to address the user feedback in terms of ease of use for cStor provisioning as well as to make a way in the schema to perform Day 2 Operations using GitOps. - Enhanced error logging of cStor storage pool with a new format for automatic alert generation. - Enhanced Jiva internal snapshot deletion when a number of internal snapshots are more than 10. The deletion happens automatically one by one. - Enhanced velero-plugin to support backup/restore for OpenEBS installed in a different namespace other than openebs namespace.- Enhanced NDM to include NodeAttributes in BD and BDC. This will support storing of node name along with the hostname on the BD and BDC CRs. - Fixes BlockDevice CRD by adding node name to the printer column. This feature will get the name of the node to which the BD is attached while performing kubectl get bd -n <openebs_installed_namespace>.- Fixes a bug in Jiva when patching and clean up operation of Jiva deployments are failing on Nodes where hostname is not the same as nodename. The fix will set nodeSelector in deployment and clean-up job after converting the nodename into hostname.- Support of provisioning Local PV in clusters where nodename and hostname are different.- Support customization of default hostpath for Jiva and Local PV. With the current implementation, customization will not persisted when a restart happened on the Node where maya-apiserver pod is running or when maya-apiserver pod is restarted. - Fixes a bug in NDM where all devices on a node were getting excluded when os-disk-exclude-filter is failed to find the device where OS is installed. - Fixes a bug in snapshot controller where snapshot operation is not throwing any error for invalid cas-type. This fix will add cas-type validation before triggering the snapshot operations. The valid cas-type are cStor and Jiva.- Fixes the bug where more than required BlockDevicesClaims are created for requested SPC in auto pool method. - Fixes an issue in maya-api installer to skip re-apply of default SPC and SC resources if they were installed previously by older version(s) of maya or prior to mayaapi-server restart(s) - Fixes a bug in cStor pool when cStor Storage Pool management creates pool if pool import failed when a disk is not accessible momentarily just at the time of import. cStor storage pool will be in the pending state when this scenario occurs. This PR will fix cStor pool creation by looking on Status.Phase as Init or PoolCreationFailed to create the pool. If Status.Phase is any other string, cStor Storage Pool management will try to import the pool. This can cause impact to the current workflow of Ephemeral disks, which works as of now, as NDM can't detect it as different disk and recognizes as the previous disk.- Fixes a bug during a cleanup operation performed on BlockDevice and clean up job is not getting canceled when the state of BlockDevice is changed from Active to other states. - Fixes a bug in NDM where cleanup jobs remain in pending state in Openshift cluster. The fix will add service account to cleanup jobs, so that clean-up job pods acquire privileged access to perform the action. |
