Veeam Agent for Linux and RHEL 7.5 crash

Veeam Logoby PTide » Wed Apr 11, 2018 10:14 am

Issue
Using Veeam Agent for Linux 2.0 or earlier on the latest release of Red Hat Enterprise Linux (RHEL) 7.5 and its derivatives (CentOS 7.5, Oracle RHCK 7.5) causes the operating system to crash during backup snapshot creation.

Cause
veeamsnap kernel module used in Veeam Agent for Linux 2.0 and earlier is not compatible with newly released RHEL 7.5 kernel 3.10.0-862

More info
We are researching the issue in collaboration with RedHat. Status updates will be posted here and in KB2659

13.06.2018 UPDATE: The fix is available via support team.
03.07.2018 UPDATE: New 2.0.1 version that addresses the issue is available via repositories.

RHEL 7.4 has been updated with the 3.10.0-862 kernel and is exhibiting the same issue.

Does this happen even if the module is recompiled from source? I know our module uses some ABI calls that are not marked as stable and thus could break between kernel trains in RHEL7.

RHEL 7.5

Veeam Logoby stevelin » Fri Apr 20, 2018 5:09 pm

I've been testing veeam linux agent on a RHEL 7.4 physical oracle server in preparation of the Oracle plugin becoming available later this year. Last week we did our normal monthly patch cycle on this dev host and it patched to RHEL 7.5. Now when I try to run a backup through veeam the server reboots. I tried uninstalling and reinstalling and setting the backup up from scratch but get the same behavior. Run a backup, reboot and backup fails.

Anyone else seeing this issue?

Hi,

This is a known issue, we are working on the fix. Please note that even if you recompile the module from source it won't work on 3.10.0-862

I too am experiencing this problem. Have been evaluating the Agent on a server that is due to go into production soon and yesterday I performed some updates and now the server crashes. Do we know how long it will take to fix? This could dictate when our server can go into production or we use alternative backup methods.

Thanks
Gary

Support for 7.5 will be introduced in the next VAL update which will take at least a month to be released.

I have 2 systems that are running RHEL 7.5 with Kernel 3.10.0-862.el7.x86_64 and VAL 2.0.0.400, one (Dell PowerEdge R720xd) has been successfully backing up for about 3 weeks and another (Dell PowerEdge R630) for 7 days. I have two other systems, however, (Dell PowerEdge R330's) that exhibit the same crashing behavior which lead me to this post today. Is this expected that some systems work and others don't? Should I submit a support request to include information on working vs. non-working systems? Is it know what the root cause of the issue is? Should I downgrade kernel versions to be on the safe side for my systems that are working (if so what version is safe)?
thanks

Support will tell you like they did me, RHEL 7.5 is not supported.

Hi,
Is this expected that some systems work and others don't?

We've observed such behaviour during tests. For now it can be described as follows:
If the module has been built via dkms on 7.4 system with kernel version < 3.10.0-862, then dkms will fail to rebuild the module after kernel update, BUT weak-updates will kick in and the module might keep working. This is not supported as we don't know potential pitfalls of such approach.

I have also seen this issue on a test server that was recently updated to 7.5. For now we will have to delay updating the production servers until this is resolved which becomes a serious issue in another month. We will have to ask for an exception since the servers can't be patched as it will break backups.

Hi,
and when is the delivery date of this new release?!
We get really in trouble with the auditor ..... because of "old" kernels .... or not existing backups!
