Oracle Linux: How to Resize an EXT3/EXT4 Filesystem
(Doc ID 445215.1)
Last updated on MAY 09, 2023
Applies to:
Linux OS - Version Enterprise Linux 3.0 and laterOracle VM - Version 2.1 to 3.4.6 [Release OVM21 to OVM34]
Oracle Cloud Infrastructure - Version N/A and later
Linux x86
Linux x86-64
Linux Kernel - Version: 2.4 to 3.8
Goal
The purpose of this article is to describe how to resize (extend and reduce) an EXT3/4 filesystem on Oracle Linux.
The procedures described were performed using EXT4 filesystems on Oracle Linux 7 but equally apply to EXT3/4 on earlier and later OL releases.
