RHEL 9.4 image Showing only 10GB of diskspace on / filesystem

Poorna-Gottimukkula1 commented 5 months ago

What happened:

The allocated size for the root directory (/) is 10 GB instead of 120 GB

[root@test-vm-rhel9-4 ~]# df -h
Filesystem           Size  Used Avail Use% Mounted on
devtmpfs             4.0M     0  4.0M   0% /dev
tmpfs                7.5G     0  7.5G   0% /dev/shm
tmpfs                3.0G   25M  3.0G   1% /run

/dev/mapper/mpatha2  960M  189M  772M  20% /boot
tmpfs                1.5G     0  1.5G   0% /run/user/0
[root@test-vm-rhel9-4 ~]#

What you expected to happen: The expected root file system size should be 120 GB

How to reproduce it (as minimally and precisely as possible):

Download any 9.X image from https://access.redhat.com/downloads/content/279/ver=/rhel---9/9.4/ppc64le/product-software or provide download link to pvsadm command.
Build binary from latest pvsadm code.
Run the pvsadm image convert command as below.

Example:

./bin/pvsadm image qcow2ova --image-name rhel-94-04242024 --image-dist rhel --rhn-user ***** --rhn-password **** --image-url ./rhel-9.4-ppc64le-kvm.qcow2

Anything else we need to know?:

I can see that the partition number hardcode with 2 https://github.com/ppc64le-cloud/pvsadm/blob/main/cmd/image/qcow2ova/prep/templates.go#L148-L169, we may need to change this to 3 since rhel 9.x images are having the root file system on partition number 3

Environment:

pvsadm version (use pvsadm version): build binary from latest code
Environment - On-Prem or IBM PowerVS: PowerVS

OS (e.g: cat /etc/os-release):

Thanks @Poorna-Gottimukkula1 for creating this issue. As you have mentioned we have to update the partition number in update-disks script. In rhel 9.* we have 3 partitions in all disk, partition 2 is mapped for /boot and partition 3 is for /.

In the existing script to grow partitions explicitly we have hardcoded 2 which is /boot in case of all rhel 9.* images but we need to grow / which is the last partition of disk. Updated the script in this PR.
