Methods, computer program products, computer systems, and the like are disclosed that provide for the tracking of access patterns of inodes, and the issuing of inode read-ahead instructions, in order to pre-fetch inodes. Such a method can include, for example, identifying a unit of metadata in a file system, identifying a file system structure in the file system, determining whether a file structure of the file system structure is non-sequential, and, in response to a determination that the file structure is non-sequential, retrieving a list of units of metadata. In such embodiments, the file system structure is associated with the unit of metadata, and the determining includes accessing the file system structure. Further, in certain embodiments, the units of metadata identified in the list of units of metadata are stored in a storage device of the computer system.

Tracking access pattern of inodes and pre-fetching inodes

The disclosed computer-implemented method for storing information within hybrid storage with local and cloud-based storage devices may include (1) dividing, if required, at the computing device, a file into multiple portions, (2) storing a first portion of the multiple portions as at least one first respective separate object on a local volume stored on the local storage device, (3) storing a second portion of the multiple portions as at least one second respective separate object on a cloud-based volume stored on a cloud-based storage device, and (4) naming each stored portion of the file with a respective object name comprising file metadata describing respective characteristics of the respective portion of the file. Various other methods, systems, and computer-readable media are also disclosed.

Systems and methods for storing information within hybrid storage with local and cloud-based storage devices

Disclosed herein are methods, systems, and processes to track access patterns of inodes, and to issue read-ahead instructions to pre-fetch inodes into memory. A location of a unit of metadata in a metadata storage area is determined. Another location in the metadata storage area that corresponds to a current metadata read operation is determined. Whether a metadata read-ahead operation can be performed is determined using the location of the unit of metadata and the another location. In response to a determination that the metadata read-ahead operation can be performed, the metadata-ahead operation is issued.

Disclosed herein are methods, systems, and processes track access patterns of inodes, and to issue read-ahead instructions to pre-fetch inodes into memory. An inode is accessed and a directory of the inode is determined. Also determined is whether an entry for the directory exists in a global inode list. If the entry exists in the global inode list, whether a file structure of the directory is sequential or non-sequential is determined. If the entry does not exist in the global inode list, a new entry for the directory is added in the global inode list.
