Issues on CentOS 8 Stream

[doublem]

Hi,

I am trying VAL on CentOS 8 Stream and do not get it to work. The veeamsnap module does not load.

Is it possible to get VAL working on the "Stream" flavor of CentOS 8 or is this not supported? (Going to be?)

Which is the error you are receiving?

Failed to create snapshot probably related to the fact that there is no veeamsnap for the current kernel:

Hi,

No, VAL doesn't support CentOS Stream.

The error that you see indicates that something went wrong during veeamsnap module installation. Which version did you install - kmod, or dkms?

Thanks!

[doublem]

Code: Select all

# rpm -qa | egrep -i 'veeam|dkms'
kmod-veeamsnap-3.0.2.1185-4.18.0_80.el8.x86_64
veeam-release-el8-1.0.7-1.x86_64
veeam-3.0.2.1185-1.el8.x86_64
dkms-2.7.1-2.el8.noarch

I installed the kmod-version (I guess). Is it possible to install another version and dynamically build new modules?

[PTide]

This one might work, give it a try.

Thanks

[doublem]

Thanks!
Got is working...

Code: Select all

# yum install veeamsnap-3.0.2.1185-1.noarch.rpm
# yum install veeam

# wget https://mirror.hh.se/centos/8-stream/BaseOS/x86_64/os/Packages/kernel-headers-4.18.0-144.el8.x86_64.rpm
# wget https://mirror.hh.se/centos/8-stream/BaseOS/x86_64/os/Packages/kernel-devel-4.18.0-144.el8.x86_64.rpm

# yum localinstall kernel-headers-4.18.0-144.el8.x86_64.rpm kernel-devel-4.18.0-144.el8.x86_64.rpm

# dkms build   -m veeamsnap -v 3.0.2.1185
# dkms install -m veeamsnap -v 3.0.2.1185
# dkms status
veeamsnap, 3.0.2.1185, 4.18.0-144.el8.x86_64, x86_64: installed

Thank you for getting back to us with the info!

This solution worked for me as well on Centos 8.0
# uname -r
4.18.0-147.5.1.el8_1.x86_64

# rpm -qa |grep veeam
veeam-3.0.2.1185-1.el8.x86_64
veeam-release-el8-1.0.7-1.x86_64
veeamsnap-3.0.2.1185-1.noarch

1. I uninstalled veeamsnap and veeam > dnf remove kmod-veeamsnap-3.0.2.1185-4.18.0_80.el8.x86_64
Thi uninstalled both the veamsnap and veeam itself.

2. Downloaded and installed > yum install veeamsnap-3.0.2.1185-1.noarch.rpm

This required a slew of other rpms that were installed.

3. Installed veeam > yum install veeam.

Ran the backup and it worked as it should.
