Usage

There are some prerequisites that need to be met before enabling lvm-localpv support in OpenEBS:

1. All the nodes must have LVM2 utils package installed
   • You can install the package using the following command:

     sudo apt-get update && sudo apt-get install lvm2 -y

2. All the nodes must have dm-snapshot Kernel Module loaded - (Device Mapper Snapshot)
   • You can check if the module is loaded using the following command:

     lsmod | grep dm_snapshot

   • If the module is not loaded, you can load it using the following command:

     sudo modprobe dm_snapshot

NOTE: The commands above are for Ubuntu, please replace them with the appropriate commands for your OS.

You can find more information on the project repository here.

There is an official Helm chart for deploying the OpenEBS with lvm-localpv support enabled.

You can find the chart here.

You can use the following command to install the OpenEBS with lvm-localpv support enabled using Chainguard's image:

helm install openebs --namespace openebs openebs/openebs \
      --set lvm-localpv.enabled="true" \
      --set lvm-localpv.lvmPlugin.image.registry="cgr.dev" \
      --set lvm-localpv.lvmPlugin.image.repository="chainguard/lvm-driver" \
      --set lvm-localpv.lvmPlugin.image.tag="latest" --create-namespace
