Analysis:

Code: Select all

[root@host ~]# ls -ld /boot/efi
drwx------. 3 root veeam 4096 Jan  1  1970 /boot/efi
[root@host ~]# 

We can clearly see that /boot/efi has group "veeam", while RHEL 9 ships it with group "root".

The workaround is therefore simple. Change things back to how they were:

Code: Select all

umount /boot/efi && mount /boot/efi

Note: the above is my personal workaround. It is not a solution.

Hello,

Which version of VAL are you running?

[Gamut]

We appear to be running version 6.1.2.1781 of the Veeam Agent for Linux:

Code: Select all

[root@host ~]# date
Wed Jun 19 11:02:28 AM CEST 2024
[root@host ~]# rpm -q --queryformat '%{NAME}\t%{VERSION}\n' -- veeam-libs veeam-nosnap 
veeam-libs	6.1.2.1781
veeam-nosnap	6.1.2.1781
[root@host ~]#

+1, we just bumped into this on our RHEL8 NFS cluster. Thanks for reporting it here Gamut, saved me a lot of headache!
