Techniques are provided for utilizing a log to free pages from persistent memory. A log is maintained to comprise a list of page block numbers of pages within persistent memory of a node to free. A page block number, of a page, within the log is identified for processing. A reference count, corresponding to a number of references to the page block number, is identified. In response to the reference count being greater than 1, the reference count is decremented and the page block number is removed from the log. In response to the reference count being 1, the page is freed from the persistent memory and the page block number is removed from the log.

Freeing pages within persistent memory

Techniques are provided for coordinating snapshot operations across multiple file systems. A notification may be received that a snapshot of data stored across a persistent memory file system and a storage file system is to be generated. Forwarding, of modify operations from a persistent memory tier to a file system tier for execution through the storage file system, may be enabled. Framing may be initiated to notify the storage file system of blocks within the persistent memory file system that comprise more up-to-date data than corresponding blocks within the storage file system. In response to the framing completing, a consistency point operation is performed to create the snapshot and to create a snapshot image as part of the snapshot.

Coordinating snapshot operations across multiple file systems

Presented herein are system and method for providing a non-disruptive mechanism for splitting a parent volume located on a first aggregate into a new volume, the method comprising: splitting the parent volume, by the network storage system, into a new volume, wherein the new volume comprises an application; and providing a snapshot of the parent volume at the new volume.

Non-disruptive automatic application regrouping

Presented herein are methods, non-transitory computer readable media, and devices providing an application centric view of storage within a network storage system, which include: creating an application instance, by the network storage system, wherein the application instance comprises at least one application-component determined based on application configuration information of the application instance; tracking the application configuration information of the application; and displaying the application configuration information in view of the storage within the network storage system.
