Extending VMDK file and resizing the partition – SLES 10 Linux

April 7th, 2009 Comments off

1. ESXi 3.5 Extending the VMDK file [Virtual Machine Hard Disk]

The main reason behind this is the fact that I needed more space for 2 more Oracle databases on a SLES10 Linux system. The partition mounted on /u01 was initially created as 21GB but I quickly depleted the space with 3 oracle 10g databases that took more than 17GB and the space left was not sufficient for the 2 new databases that I had to create.

Before I advanced with the extension of the VMDK file I connected to each separate instance and performed “shutdown immediate” command as sysdba.
Then I stopped the listener, dbconsole, isqlplus and once I confirmed that no oracle related processes were present on the system I performed a shutdown “shutdown -h now”.

In order to extend an existing hard drive attached to a virtual machine you have to make sure no snapshots of the virtual machine are present. I know that this is quite uncomfortable considering the risky operation that you are about to perform but there is a work around. (The work around is not in this post, so please let me know if you are interested or simply search for it. There is a good chance that I will have an article concerning that topic)

Configuring and Using Raw Partitions for the Oracle Shared Storage

For the purpose of my cluster I will use raw partitions that are shared disks on the ESXi host.
First I will identify my needs for shared disks and them will create them and format them accordingly.

After some high level overview of my requirements I have created the following list of required files:

asm01.vmdk = 6GB [ ORADATA ]
asm02.vmdk = 2GB [Application data]
asm03.vmdk = 4GB [FLASH]
ocr.vmdk = 256MB [Cluster Registry]
voting.vmdk = 40MB [Voting disk]
spfile.vmdk = 16MB [Parameter configuration]
