Extend partition from VMWare in Oracle Linux – part 2   Recently updated !

This entry was posted in Linux and tagged Oracle Linux 9 on by

The client uses VMWare as virtualization platform for the Oracle Database VMs (yes, he is aware of the License implications).

The VM is running out of space in two partitions. The VMWare Admin extended the disks on their platform. Now I need to make this extension visible in Oracle Linux. This things we do once every 10 years, when versions, filesystems and tools already changed.

For this post in 2025, I’m using Oracle Linux 9, xfs filesystems. All operation are online, with databases running.

I divide this post in two parts:

Extend a mountpoint within several partitions in a block device

oracle@vmware-vm01 MIG01C $ cat /etc/system-release 
Oracle Linux Server release 9.6

The partition tree is below, and I need to increase the /u01 from 50G to 100G. The disk is /dev/sda

[root@vmware-vm01 ~]# lsblk
