A data inconsistency is detected in a file system data block of a file system. The file system includes a set of files, each file includes a set of file system data blocks. Information regarding a file including the data inconsistency is provided to a client of the file system. Based on the information, the client is enabled to determine an action for recovering from the data inconsistency.

Managing data inconsistencies in files of file systems

A method, computer program product, and computer system for receiving, at a computing device, an I/O request directed to a compressed data portion of a file system. A field associated with the compressed data portion may be determined to be invalid. An error may be generated in response to determining that the field associated with the compressed data portion is invalid. The file system may be maintained in an online status while the compressed data portion is invalid.

A method is used in managing data inconsistencies in file systems. A data inconsistency is detected in a file system data block of a file system. The file system includes a set of file system data blocks. Information regarding the data inconsistency is provided to a client of the file system. Based on the information, the client is enabled to determine an action for recovering from the data inconsistency.

Managing data inconsistencies in file systems

A method, computer program product, and computing system for generating a first file system for use within a data storage array. A first temporary storage space is defined within the data storage array for use during a file system recovery event. The size of the first temporary storage space is defined based, at least in part, upon the actual utilization of the first file system.

Storage management system and method

A method is used in recovering duplicate blocks in file systems. A duplicate file system block is detected in a file system. The duplicate file system block is referred by a first inode associated with a first file of the file system and a second inode associated with a second file of the file system. Metadata of the duplicate file system block is evaluated. Based on the evaluation, a set of inodes in the file system is determined. Each inode of the set of inodes refer to the duplicate file system block. Based on the determination, the set of inodes is updated.

Recovering duplicate blocks in file systems

A method is used in analyzing mapping objects of file systems. Each mapping object of a set of mapping objects of files of a file system is analyzed by iterating over the set of mapping objects. A file is associated with a first mapping object of the set of mapping objects and a snapshot copy of the file is associated with a second mapping object of the set of mapping objects. The second mapping object shares a subset of a set of storage objects associated with the first mapping object. Information for each storage object of the set of storage objects associated with each mapping object of the set of mapping objects is stored. Based on the stored information, each storage object of the set of storage objects associated with each mapping object of the set of mapping objects is processed.
