Abstract: Some examples relate to updating of metadata of objects in a file system. In an example, in response to an invocation by an application to update metadata related to a plurality of objects of a file system, an API may initialize a new metadata deduplication database based on an active metadata deduplication database that includes the metadata related to the plurality of objects and a deduplication key linked with the metadata. API may add new metadata to the new metadata deduplication database. API may associate a new deduplication key with the new metadata in the new metadata deduplication database. API may initialize a new translation database. API may add the new deduplication key to the new translation database. API may associate the respective object IDs of the plurality of objects with the new deduplication key in the new translation database.

Abstract: In one example, a system is described in which a storage device, communicatively coupled to a processor, includes an inconsistency detection and reconstruction tool. The inconsistency detection and reconstruction tool may create a database including metadata associated with hierarchical organization directories and policy and configuration data files in a file system. Further, the inconsistency detection and reconstruction tool may perform consistency check of one or more of the hierarchical organization directories, the policy and configuration data files and the metadata to detect inconsistencies. Furthermore, the inconsistency detection and reconstruction tool may reconstruct one or more of the hierarchical organization directories, the policy and configuration data files and the metadata based on the outcome of the consistency check.

Abstract: In one example, a system is described in which a storage device, communicatively coupled to a processor, includes a file system management module. This file system management module may create a hierarchical organization directory that is a device and an operating system independent under a root directory in a namespace of a file system. Further, the file system management module may create a user directory under the hierarchical organization directory. Furthermore, the tile system management module may create policy and configuration data for the user directory. In addition, the file system management module may store the policy and configuration data created for the user directory in the hierarchical organization directory.

Abstract: In one example, a request for storage of an extended attribute (EA) of a file system object is received. A storage location for the EA is determined from a plurality of storage locations, based on one or more characteristics of the EA, the plurality of storage locations including an inode, a first storage file accessible by a first B+ tree, and a second storage file accessible by a second B+ tree. The EA is accordingly stored in the determined storage location.

Abstract: Examples described herein relate to a computing system, a method and a non-transitory machine-readable medium for handling a request directed to a file in first filesystem having a filesystem instance being a content addressable storage objects. The computing system may also include a general-purpose second filesystem including its backing store within the filesystem instance of the first filesystem. Moreover, the computing system includes a first filesystem server to receive the request for an operation directed to the file in the first filesystem from an application. The first filesystem server may redirect the request to the second filesystem if the operation is a metadata operation; else redirect the request to the first filesystem.
