NET 4000 Chapter Notes - Chapter 7.4.5: Paging, Ext3, Disk Partitioning
Document Summary
The file system determines how a computer"s files are organized on a hard drive. The following table describes several common file systems: The second extended file system (ext2) is one of the oldest linux file systems still available. ext2 stores data in a standard directory and file hierarchy. The maximum file size supported is 2 tb. An ext2 volume can be up to 4 tb in size. File names can be up to 255 characters long. It does not use journaling (which is used in most modern file systems). As a result, ext2 takes a long time to recover if the system shuts down abruptly. The third extended file system (ext3) is an updated version of ext2 that supports journaling. Before committing a transaction to a storage device, the ext3 file system records the transaction to the journal and marks it as incomplete. After the disk transaction is complete, the file system marks the transaction as complete in the journal.
