Patent number: 11816093Abstract: Techniques are provided for storage tier verification checks. A determination is made that a mount operation of an aggregate of a set of volumes stored within a multi-tier storage environment has completed. A first metafile and a second metafile are maintained to track information related to the storage of objects of a volume of the aggregate within a remote object store that is a tier of the multi-tier storage environment. A distributed verification is performed between the first metafile and the second metafile to identify an inconsistency. Accordingly, the first metafile and the second metafile are reconciled to address the inconsistency so that storage information within the first metafile and the second metafile are consistent.Type: GrantFiled: November 29, 2021Date of Patent: November 14, 2023Assignee: NetApp, Inc.Inventors: Kayuri Hasmukh Patel, Qinghua Zheng, Sumith Makam, Kevin Daniel Varghese, Yuvraj Ajaykumar Patel, Sateesh Kumar Pola, Sharmi Suresh Kumar Nair, Mihir Gorecha

Patent number: 11625303Abstract: Presented herein are methods, non-transitory computer readable media, and devices triggering a metadata recovery process within a network storage system, which include: dividing metadata into metadata segments, wherein each of the metadata segments is tasked to perform a specific file system operation function, validating each of the metadata segments during the specific file system operation function; upon failure to validate at least one of the metadata segments, triggering an automatic repair process while maintaining the operation function tasked to the metadata segment, and upon finalizing the automatic repair process, resuming the specific file system operation function tasked to the metadata segment.Type: GrantFiled: June 23, 2017Date of Patent: April 11, 2023Assignee: NetApp, Inc.Inventors: Sushrut Bhowmik, Vinay Kumar B C, Sreenath Korrakuti, Arun Kumar Pandey, Sateesh Kumar Pola

Publication number: 20230024060Abstract: Systems and methods for supporting dynamic disk growth within a virtual storage appliance are provided. According to one embodiment, a portion of a logical size of respective hyperscale disks provided by a hyperscaler are provisioned for use by a virtual storage system as backing for respective file system disks. To accommodate growth, block numbers for the file system disks are pre-allocated within a sparse space of a contiguous sequence of block numbers corresponding to a number of blocks represented by the logical size. Metadata is maintained for the file system disks regarding a range of the pre-allocated block numbers that are available for use. Responsive to a triggering condition, the provisioned portion of a hyperscale disk is increased and subsequently, responsive to detecting a change in a size of the hyperscale disk by the virtual storage system, a size of the corresponding file system disk is updated within the metadata.Type: ApplicationFiled: September 8, 2021Publication date: January 26, 2023Inventors: Mrinal K. Bhattacharjee, Jagadish Vasudeva, Sateesh Kumar Pola
