ONLINE FILE SYSTEM CONSISTENCY CHECK FOR CONTAINER DATA ON A CLUSTERED FILESYSTEM

Abstract:

Online file system consistency check for container data on a clustered file system is provided via identifying inodes (index nodes) of a group of files in a clustered file system based on a cyber-resiliency for the clustered file system; grouping the inodes based on a buffer size allocated to a FSCK (File System Consistency Check) operation; passing the inodes of to the FSCK operation in a single iteration when a total size of the inodes is less than the buffer size; or when the total size of the inodes is greater than the buffer size, identifying inodes that belong to a first container and that belong to a second container; passing the inodes that belong to the first container to the FSCK operation in a first iteration; and passing, after the first iteration completes, the inodes that belong to the second container to the FSCK operation in a second iteration.
