TopoLVM - In Cluster
TopoLVM is a capacity aware storage provisioner which can make use of physical volumes.
The following steps are one way to set it up, however, consult the documentation for a full breakdown of everything possible with TopoLVM.
Create the target volume group on your hosts
TopoLVM requires access to a volume group on the physical host to work, which means we need to set up a volume group on our hosts. By default, TopoLVM will use the controllers as storage hosts. The genestack Kustomize solution sets the general storage volume group to vg-general. This value can be changed within Kustomize found at kustomize/topolvm/general/kustomization.yaml.
Info
Simple example showing how to create the needed volume group.
# NOTE sdX is a placeholder for a physical drive or partition.
pvcreate /dev/sdX
vgcreate vg-general /dev/sdX
Once the volume group is on your storage nodes, the node is ready for use.
