Exalogic: Procedure To Increase The Logical Volume Size Of Root Filesystem And Swap On Disk Containing Four Primary Partitions (Doc ID 2059158.1)

Last updated on MAY 01, 2024

Applies to:

Oracle Exalogic Elastic Cloud Software - Version 2.0.6.0.0 and later
Linux x86-64
Oracle Virtual Server x86-64

Purpose

The procedure in this document provides a step-by-step procedure to increase the root partition size and swap of the guest vServers when it is no longer possible to use ModifyLVMImg.sh.

Our supported procedure to increase the size of the root partition is by performing the steps described in the following MOS notes:

<Note 1590316.1>: Script: To Increase Root File System and Swap Space of Exalogic Guest Base Template in EECS v2.0.6.x.x

<Note 2039276.1>: Exalogic: How To Repartition The Root Filesystem Of An OL6 Guest vServer

The procedure described in the above documents leverages the ModifyLVMImg.sh script, which performs the resizing by creating new partitions on the root disk. If the script is executed twice, the disk ends up with four primary partitions (the maximum number of primary partitions), and subsequent attempts to run the script to resize results in a failure. Any further increase in root partition will require the existing partitions to be resized. The procedure in this document provides a step-by-step procedure to increase the root partition size when it is no longer possible to use ModifyLVMImg.sh.

NOTE: It is recommended to perform installs of applications on NFS shares mounted on guest vServers and not have large local disks attached to guest vServers. With application installs on NFS shares, the local disks should be lightweight and used for log files, temporary files, and for operating system functionality.

The procedure in this document may be used to resize the root partition, but it is highly recommended to start planning to migrate the application files on local disk to NFS shares to align with the recommendation.
