Failed to create volume snapshot.Failed to take volume snapshot.Failed to load module [veeamsnap]

Hi,
This is the first time to use Veeam Agent for Linux.
1.When I do a backup job, it fails with the error like this:

Code: Select all

2.And I check my linux host like this :

2)linux OS and installed Veeam agent like this, I think I have install the right Veeam agent:

Code: Select all

[root@oracledb sbin]# uname -r
3.10.0-957.el7.x86_64
[root@oracledb sbin]# cat /etc/redhat-release
CentOS Linux release 7.6.1810 (Core)
[root@oracledb sbin]# rpm -qa | grep veeam
veeam-5.0.0.4318-1.el7.x86_64
kmod-veeamsnap-5.0.0.4318-1.el7.x86_64

3. I find help in the document below, but it doesn't solve my problem.

Sincerely hope to get your help.

Hi,

Do you have EFI SecureBoot enabled by any chance? Please try to load the module manually:

Code: Select all

modprobe veeamsnap

Thanks!

[idench]

Sorry, I don't really understand your question, Could you give me more details?

[idench]

After I exute "modprobe veeamsnap", it reply"modprobe: FATAL: Module veeamsnap not found.".
I check out my Veeam agent installation, I have install rpm :veeam-5.0.0.4318-1.el7.x86_64 and kmod-veeamsnap-5.0.0.4318-1.el7.x86_64 according my 64-bit CentOS 7

Code: Select all

[root@oracledb sbin]# uname -r
3.10.0-957.el7.x86_64
[root@oracledb sbin]# cat /etc/redhat-release
CentOS Linux release 7.6.1810 (Core) 
[root@oracledb sbin]# rpm -qa | grep veeam
veeam-5.0.0.4318-1.el7.x86_64
kmod-veeamsnap-5.0.0.4318-1.el7.x86_64
[root@oracledb sbin]# rpm -qa | grep kernel-headers
kernel-headers-3.10.0-957.el7.x86_64
[root@oracledb sbin]# modprobe veeamsnap
modprobe: FATAL: Module veeamsnap not found.
[root@oracledb sbin]# modprobe kmod-veeamsnap
modprobe: FATAL: Module kmod-veeamsnap not found.

The question was whether you use UEFI-based machine or BIOS-based machine. If the former, then is you secure boot activated. It seems that the issue is not related to that though...

It seems that for some reason the installation procedure went wrong, so I suggest you to try reinstalling the agent (both veeam and veeamsnap). Make sure to install kmod-veeamsnap.

If that does not help, then please use veeamconfig grabLogs command to export logs and share the archive with me.

Thanks!

Thank you for your help. But I have reinstall my Python3.8 to 3.6 , kmod-veeamsnap-5.0.0.4318-1.el7.x86_64.rpm and veeam-5.0.0.4318-1.el7.x86_64.rpm, It seems no help. The error occured again.
And for some reasons, I can't email you.
Could you have other suggestion?
Thank you.

Please use forum private messages. Also I'd strongly recommend to open a support case and post your case ID in this thread.

Thanks!

Hi! just to you know, in my case issue was solved disabling "boot options" --> "secure boot" on my Linux VM

[ksl28]

Disabling secure boot worked for me as well
