Failed to execute agent management command getMachineSize. BIOS boot partition size exceeds limit.

[sfaits]

I have two Oracle linux virtual machines running OL 7.9, that I am attempting to get backups of with the linux veeam agent but when the job runs I am get the following error. This is with the agent version 6.1.2.1781. Kernel is 4.14.35-2047.528.2.4.el7uek.x86_64

Error: Failed to execute agent management command getMachineSize. BIOS boot partition size exceeds limit.
Failed to detect bootloader on [/dev/sda].

I have a case opened, they are currently looking at the logs. (07303096)

Anyone seen anything like this before?

I am not seeing this on my RHEL VMs running 7.9 or 8.9

Thanks!

And the /boot partition is sized at 509MB, 118M used, 392M available

Hi,

Try to set following value in the /etc/veeam/veeam.ini file:

From (default):

Code: Select all

# Extra amount of RAM equal to GPT BIOS boot partition size is consumed during backup. This key sets the upper limit (MiB):
# biosBootPartitionLimit = 32

To (here we set 260M, as your 2nd partition's size is 256M):

Code: Select all

# Extra amount of RAM equal to GPT BIOS boot partition size is consumed during backup. This key sets the upper limit (MiB):
biosBootPartitionLimit = 260

After change, restart Veeam Agent service

Thank you Rovshan, that got me past the error and I was able to successfully backup the VM.
Never had to do that for any of the linux servers I've backed up so I was very confused.

Thank you again for your assistance
