An example method for filesystem pass-through on lightweight virtual machine containers includes executing a container on a host, and creating a file system overlay in a local file system storage located on the host. The example method further includes copying files and directories into the file system overlay from a shared file system until the file system overlay is fully populated. The file system overlay is fully populated when all the files and directories from the shared file system are copied into the file system overlay. Once fully populated, completion is marked which indicates the file system overlay is fully populated, where marking the completion prevents accessing a read-only base image within the shared file system.

Filesystem pass-through on lightweight virtual machine containers

Flexible deprovisioning of distributed storage is disclosed. For example, an orchestrator executes on a processor to measure a current storage demand factor based on a current count of service guests and a storage capacity of a plurality of storage nodes. A projected storage demand factor is calculated by (i) adjusting the current count of service guests with a timing factor resulting in a projected count, and (ii) combining the projected count with a storage class associated with the service guests. The orchestrator determines that the projected storage demand factor is lower than the current storage demand factor, and in response requests termination of a first storage node of the plurality of storage nodes based on the first storage node lacking an active communication session with the service guests. Cancel termination of the first storage node based on an association between the first storage node and a second storage node.
