Solution 1634652.1 : ODAVP: How to resize the VM shared repository

Applies to:

Oracle Database Appliance - Version All Versions and later
Oracle Database Appliance Software - Version 2.8.0.0 to 2.10.0.0
Information in this document applies to any platform.

Goal

The scope of this bulletin is provide the steps resize a VM (Virtual Machine) shared repository on ODA VP (Oracle Database Appliance Virtualize Platform)

Solution

The Steps

1. Check the shared repo device name and size

oakcli show repo [<repo_name> -node <0|1>]

ie:

# oakcli show repo shared1 -node 0
Resource: shared1_0
   AutoStart       :   restore
   DG              :   DATA
   Device          :   /dev/asm/shared1-331
   ExpectedState   :   Online
   MountPoint      :   /u01/app/sharedrepo/shared1
   Name            :   shared1_0
   Node            :   all
   RepoType        :   shared
   Size            :    24000
   State           :   Online

2. Resize the shared repo

Using acfsutil, issuing

/sbin/acfsutil size
Usage: acfsutil [-h] size [-|+]nnn[K|M|G|T|P] <path>

i.e.:
# acfsutil size +100000m /u01/app/sharedrepo/shared1
acfsutil size: new file system size: 1181116006400 (1126400MB)

You can check the new repo size issuing (the ACFS device name is reported on 'oakcli show repo'):

/sbin/advmutil volinfo <ACFS device name>

ie:
# /sbin/advmutil volinfo /dev/asm/shared1-331
Device: /dev/asm/shared1-331
Interface Version: 1
Size (MB): 124000
Resize Increment (MB): 32
Redundancy: high
Stripe Columns: 4
Stripe Width (KB): 128
Disk Group: DATA
Volume: SHARED1
Compatible.advm: 11.2.0.0.0

Note: from ODA sw version 12.1 a new OAKCli command feature is possible:

# oakcli configure repo
Usage:
oakcli configure repo <reponame> -incsize <size>[M|G]
where:
   reponame              - configures a repo with reponame
   -incsize              - "<size>[M|G]" increases the repo size by <size>
                           - by default unit "M" is considered
