superblock

A partition boot record is usually referred to as the partition root superblock .

The most common limitation is the offset allowed to the start of the partition superblock.

An aggregate is an array of disk blocks containing a specific format that includes a superblock and an allocation map .

At the root of each file system is the superblock, which describes and maintains state for the file system.

A file system will have one root dentry (referenced in the superblock), this being the only dentry without a parent.

It doesn't take much to make a superblock dirty, cause fragmentation, mess up inodes, or cause repeating JFS errors in the errpt.

In memory, the superblock provides the necessary information and state to manage the active (mounted) file system.

One important element of the superblock is a definition of the superblock operations.

The superblock is a structure that exists on disk (actually, multiple places on disk for redundancy) and also in memory.

The superblock is typically stored on the storage medium but can be created in real time if one doesn't exist.

This section explores the superblock, the index node (or inode), the directory entry (or dentry), and finally, the file object.

The superblock is the container for high-level metadata about a file system.

On disk, the superblock provides information to the kernel on the structure of the file system on disk.

These objects are the superblock, inode, dentry, and file.

The superblock is a structure that represents a file system.

Figure 3 provides a simplified view of the superblock and its elements.

Instead of placing LILO in the new Linux logical partition superblock, it is placed in the master boot record.

This links to the superblock structure, which I'll explore next.
