Abstract: Storage for persistent volumes (PVs) of a container-based host is provided by, in a PV creation operation, (1) allocating a region having a path in the filesystem and assigning a respective tree quota corresponding to a specified PV size, (2) mounting the path in association with a path identifier, and (3) supplying the path identifier to the container-based host for use as a PV identifier. In response to data operation requests of the container-based host including the path identifier as a PV identifier, corresponding operations are performed in the region using the path associated with the path identifier. A large number of tree quotas can be created and thus support scaling PV support as needed for container-based workloads.

Abstract: Techniques are directed to performing NAS server migration (e.g., between arrays or appliances). Such a technique involves, after a NAS server has accessed source volumes on a source array through a tunnel endpoint on the source array, configuring the NAS server to access the source volumes through source devices of the source array in place of the tunnel endpoint on the source array. Such a technique further involves, after the NAS server is configured to access the source volumes through the source devices of the source array, moving the NAS server from the source array to a destination array. Such a technique further involves, after the NAS server is moved from the source array to the destination array, configuring the NAS server to access destination volumes on the destination array in place of the source volumes on the source array.
