A.3. Upgrading Your File System
 | Note |
|---|
| | This section only pertains to users performing
an upgrade from Red Hat Linux version 7.1 or earlier, or from a Red Hat Linux 7.2 or 7.3
installation where ext2 was chosen as the file system. |
If the installation program detects the ext2 file system on your
Red Hat Linux system, you can choose to retain your current ext2 file system or
migrate to the ext3 file system.
The following is a brief description of the ext2 and ext3
file systems, and how they can be utilized.
ext2 — An ext2 file system supports
standard Unix file types (regular files, directories, symbolic links,
etc). It provides the ability to assign long file names, up to 255
characters.
Versions prior to Red Hat Linux 7.2 used ext2 file systems by
default.
ext3 — The ext3 file system is based
on the ext2 file system and has one main advantage —
journaling. Using a journaling file system reduces time spent
recovering a file system after a crash as there is no need to
fsck[1]the file system.
It is recommended, but not required, that you choose to migrate to
the ext3 file system.
If you choose to migrate to the ext3 file system, existing system
data will not be modified.
