OLT or Object Location Table is the UNIX file system component which is referenced from the primary component, superblock. This can be taken as an extension of the superblock, which locates the other structural files. OLT contains information which is needed when the UNIX file system structures, not in fixed locations, are intended to mount.
This is an 8K long structure and its replica is stored at a safe location on the disk. The OLT determines the location of the initial extents of the structural inode list and the inode number of the fileset header file. This also possesses initial inode list extent addresses and current usage table inode. At the time when it get corrupts, its replica can be used which is located at a safe location on disk. But, this may not be practical to locate the copy or both of them may found to be corrupted.
