VAL and kernel compatibility

[Andanet]

Hi all,
I've a simple question to submit regarding kernel compatibility with VAL agent.
Scenario
VAL 6.3.2
uname -r
5.15.0-205.149.5.1.el8uek.x86_64
cat /etc/redhat-release
Red Hat Enterprise Linux release 8.9 (Ootpa)
dkms status
veeamsnap, 6.3.2.1207: added

Reading KB2804 i notice:
Version Maximum Supported Kernel VAL Build Shipped with VBR Build
8.0-8.10 4.18.0-553.124.1.el8_10 6.3.2.1307 Veeam Backup & Replication 12.3.2.4465 Uses the veeamsnap kernel module.
This means I cannot use 6.3.2 VAL on that Instance in managed mode by VBR server? I need to have an AAP backup (PostgresDB) and I cannot use the "nosnap" agent.
Please let me know if I have other ways to use VAL Agent. Has anyone a previous experience about this issue?

obviously if I run backup job I receive these errors:
16:12:08 Failed to create volume snapshot
16:12:08 Failed to take volume snapshot
16:12:08 Failed to perform managed backup
16:12:08 Veeam snapshot kernel module not found.

Thanks

Hello Antonio,

I see UEK in 5.15.0-205.149.5.1.el8uek.x86_64.
So you are running a higher kernel installed from a different repository?

Hi Rovshan,
I'm not able to reply to your question because is a server in a customer infrastructure.
But if I check in yum.repos.d directory I have these repos:
ksplice-ol8.repo.osmh-backup
oracle-epel-ol8.repo.osmh-backup
osmh.repo
uek-ol8.repo.osmh-backup
mysql-ol8.repo.osmh-backup
oraclelinux-developer-ol8.repo.osmh-backup
pganalyze_collector.repo
virt-ol8.repo.osmh-backup
oci-included-ol8.repo.osmh-backup
oracle-linux-ol8.repo.osmh-backup
pgdg-redhat-all.repo

The bolded repo existing, maybe, it is an OCI instance.
The issue is due to the kernel is greater than required?
Thanks

Hi,

Seems like the machine runs Oracle Linux:


See if https://www.veeam.com/kb4394 could solve the issue.

If the machine runs in Secure Boot mode, extra steps will be needed — see the User Guide here.

You're right! It is an Oracle Linux...
Following KB4394 I receive this warning
warning: the compiler differs from the one used to build the kernel
The kernel was built by: gcc (GCC) 11.4.1 20230605 (Red Hat 11.4.1-2.1.0.1)
You are using: gcc (GCC) 8.5.0 20210514 (Red Hat 8.5.0-20.0.3)
and command ends in a failure.

PS: Secure Boot mode is disabled
