VM Panorama - remove old log disk - 2 TB

Trin — Mon, 13 Jan 2025 11:39:50 GMT

Hello!

I have a VM panorama with a system disk 81 GB and a log disk 2 TB.

No traffic and threat log under monitor showed after panorama upgrade from v10.2.8 to 11.0.0
This version 11.1.3-h4 fixed the log problem. Traffic and threat log under monitor shows again, but logging shows 3 months back in time and does not show back 2022, 2023 and 2024.

While firewalls still have logs back 2022, 2023 and 2024

I see that logs older than 3 months are deleted to write new logs. Panorama cannot delete oldest logs from 2022 first
It looks like the log disk (disk A) 2 TB is corrupted during the upgrade. I followed this link to create a new log disk 2 TB (disk B)

https://docs.paloaltonetworks.com/panorama/10-1/panorama-admin/set-up-panorama/set-up-the-panorama-virtual-appliance/expand-log-storage-capacity-on-the-panorama-virtual-appliance/add-a-virtual-disk-to-panorama-on-an-esxi-server
. It starts writing new logs and retention days increase on disk A and B. Logs older than 3 months are not deleted. So far so good.
I want to remove the old disk 2TB (disk A) and did not find any documentation on how to remove the old log disk from VM Panorama.

I do not think it is so easy to do like this:

1) show system disk details

I can see 2 disks (2x 2TB): name: sdb and sdc, state:present, size:2097152 MB, status: available, reason: admin enabled.

2) Delete disk A under managed collectors --> request system disk remove sdb --> turn off VM Panorama --> just remove a virtual disk - disk A --> turn on VM Panorma --> Done!

I heard that I need to create the third disk 2 TB to make logging redundancy first and then I can remove the disk A.

Is that true? Can you please guide me how to remove disk A?

Hello @Trin ,

Before upgrading, please read the documentation page

https://docs.paloaltonetworks.com/pan-os/11-1/pan-os-upgrade/upgrade-pan-os/upgradedowngrade-considerations

Based on what you are explaining, it may be related to the point about the collector group.

Anyway, the logging redundancy will not work (the idea is to store a copy per node, not per disk).

Maybe you can raise a case to TAC so it can be properly investigated.

Hello Ozheng

Thanks for your response

I don't have direct TAC support, but I have TAC support via the Palo Alto Partner Provider. I was told that TAC gave up and closed the case.
Now the Palo Alto Partner Provider has the case and promised that they will help me remove the old disk. I have reminded the Palo Alto Partner Provider several times without success.

So I posted the message on this forum and hope that someone can help me

Hello!

Just let you that the VM panorama is running this version 11.1.3-h4 and the firewalls are running 11.0.4-h2 (was preferred many weeks ago)

I could like to upgrade the firewalls to the preferred version 11.0.4-h6 today, but I am waiting response from the Palo Alto Parter provider.

Should I upgrade to the preferred version 11.0.4-h6 anyway?
