OpenEBS
OpenEBS is a multi-storage CSI solution. However, its important to note that its snapshot capabilities either are relatively unstable or non-existent.
OpenEBS HostPath
OpenEBS HostPath is included with ClusterTool.
It rolls out a, non-default, storageClass named openebs-hostpath
, that saves its data on the systemdisk.
OpenEBS hostPath does not support snapshots in any way, shape or form. So is not a good pick for volsync support, but might work well with CNPG.
