On-prem installation of Portworx with PX-StoreV2

This document explains how to install Portworx with the PX-StoreV2 datastore in an on-premises environment.

PX-StoreV2 is a Portworx datastore optimized for supporting IO intensive workloads for configurations utilizing high performance NVMe class devices. It’s the platform that enables PX-Fast feature that targets for workloads requiring high data ingestion rates with consistent latencies.

PX-Fast is a Portworx feature that enables an accelerated IO path for the volumes that meet certain prerequisites. It is optimized for workloads requiring consistent low latencies. PX-Fast is built on top of PX-StoreV2 datastore.

note
  • PX-Fast requires a special license. Contact the Portworx support team for obtaining this license.
  • Upgrading from a previous Portworx version to deploy PX-StoreV2 datastore is not supported.
  • Once Portworx is deployed with the PX-StoreV2 datastore, you can use all of Portworx's features except for the following:
    • XFS volumes
    • Aggregated volumes
    • PX-Cache
    • PX-Security
    • PDS

Prerequisites​

You must have a Kubernetes cluster deployed on infrastructure that meets the following minimum requirements for Portworx with PX-StoreV2:

  • Linux kernel version: 4.20 or newer is the minimum required version, 5.0 or newer is recommended, with the following packages:

    • Rhel: device-mapper mdadm lvm2 device-mapper-persistent-data augeas

    • Debian: dmsetup mdadm lvm2 thin-provisioning-tools augeas-tools

    • Suse: dmsetup mdadm lvm2 device-mapper-persistent-data augeas

      note

      During installation, Portworx will automatically try to pull the required packages from distribution specific repositories. This is a mandatory requirement and installation will fail if this prerequisite is not met.

  • A minimum of 64 GB system metadata device on each node where you want to deploy Portworx.

  • An NVMe or SSD drive type with 8 GB of memory per node.

  • A minimum of 8 cores CPU per node.

Install Portworx​

Follow the instructions in this section to deploy Portworx with the PX-StoreV2 datastore.

Generate the specs​

To install Portworx with Kubernetes, you must first generate Kubernetes manifests that you will deploy in your cluster:

  1. Navigate to Portworx Central and log in, or create an account.

  2. Select Portworx Enterprise from the Product Catalog page.

  3. On the Product Line page, choose any option depending on which license you intend to use, then click Continue to start the spec generator.

  4. Select version 2.12 or newer from the Portworx version dropdown and DAS/SAN as your platform, then click Customize at the bottom of the Summary section.

  5. On the Basic page, specify an existing namespace where you will deploy Portworx in the Namespace field and click Next.

  6. On the Storage page, select On Premises as your environment and select the type of OnPrem storage. Choose the PX-StoreV2 option and provide your metadata device path in the Metadata Path textbox, then click Next.

  7. Provide your network options and click Next.

  8. On the Customize page, choose None for the Are you running on either of these? option, then click Finish to generate the specs.

Once you've generated your specs, you're ready to apply them and deploy Portworx. You also can save your specs on Portworx Central for future reference.

Apply the specs​

Apply the specs using the following commands:

  1. Deploy the Operator:

    kubectl apply -f 'https://install.portworx.com/<version-number>?comp=pxoperator'
    serviceaccount/portworx-operator created
    podsecuritypolicy.policy/px-operator created
    clusterrole.rbac.authorization.k8s.io/portworx-operator created
    clusterrolebinding.rbac.authorization.k8s.io/portworx-operator created
    deployment.apps/portworx-operator created

  2. Deploy the StorageCluster:

    kubectl apply -f 'https://install.portworx.com/<version-number>?operator=true&mc=false&kbver=&b=true&c=px-cluster-0d8dad46-f9fd-4945-b4ac-8dfd338e915b&stork=true&csi=true&mon=true&tel=false&st=k8s&promop=true'
    storagecluster.core.libopenstorage.org/px-cluster-378d7ae1-f4ca-4f92-914d-fab038f0bbe6 created
note
  • In your output, the image pulled will differ based on your chosen Portworx license type and version.
  • For Portworx Enterprise, the default license activated on the cluster is a 30 day trial that you can convert to a SaaS-based model or a generic fixed license.
  • For Portworx Essentials, your cluster must have internet connectivity so that it can send usage information every 24 hours to renew the license on the cluster. You can convert a Portworx Essentials license to either a fixed license or SaaS-based license.

Verify your Portworx installation​

Once you've installed Portworx, you can perform the following tasks to verify that Portworx is correctly installed and using the PX-StoreV2 datastore.

Verify if all pods are running​

Enter the following command to list and filter the results for Portworx pods and specify the namespace where you have deployed Portworx:

kubectl get pods -n <px-namespace> -o wide | grep -e portworx -e px

Note the name of one of your px-cluster pods. You'll run pxctl commands from these pods in following steps.

Verify Portworx cluster status​

You can find the status of the Portworx cluster by running pxctl status commands from a pod. Enter the following kubectl exec command, specifying the pod name you retrieved in the previous section:

kubectl exec <px-pod>  -n <px-namespace> -- /opt/pwx/bin/pxctl status

The Portworx status will display PX is operational, and the StorageNode entries for each node will read Yes(PX-StoreV2).

Verify Portworx pool status​

Run the following command to view the Porworx drive configurations for your pod:

kubectl exec <px-pod>  -n <px-namespace> -- /opt/pwx/bin/pxctl service pool show
Defaulted container "portworx" out of: portworx, csi-node-driver-registrar
PX drive configuration:

The Type: PX-StoreV2 output shows that your pod is using the PX-StoreV2 datastore.

Verify pxctl cluster provision status​

  • Find the storage cluster using the following command; the status should show the cluster is Online:

    kubectl -n <px-namespace> get storagecluster

  • Find the storage nodes, whose statuses should show as Online:

    kubectl -n <px-namespace> get storagenodes
