How to resize an EXT3/EXT4 filesystem on Oracle Linux (Doc ID 445215.1)

Last updated on JULY 02, 2019

Applies to:

Linux OS - Version Enterprise Linux 3.0 to Oracle Linux 7.6 [Release RHEL3 to OL7U6]
Oracle 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 on earlier/other releases.
