is volumeMode: Block supported? #495
-
|
This is a great utility, but trying to sync an RPD PVC (volumeMode: Block) from one cluster to another and the Destination Cluster container won't start because the volumeMode is Block. container has this as an event. Unable to attach or mount volumes: unmounted volumes=[data], unattached volumes=[data keys kube-api-access-hxmll]: volume data has volumeMode Block, but is specified in volumeMounts. Is this something supported and I have configurations wrong? Thanks |

VolSync doesn't currently support |

VolSync doesn't currently support
volumeMode: blockvolumes. The main reason that we haven't added support is that there's no efficient way to calculate a diff so that we can send just the changed blocks during each sync iteration.There is upstream Kubernetes work that is hoping to provide a standard way of exposing changed blocks. Once that happens, we plan to add block volume support to VolSync.
