Failed to perform backup Snapshot deadlock detected

Failed to perform backup Snapshot deadlock detected

Veeam Logoby zx81 » Fri Feb 10, 2017 9:06 am

We installed Veeam Agent for Linux on one of our Ubuntu Linux NASs. On attempting to backup the boot drive (/dev/sda) we got the following message, soon after which the kernel panicked and we had to power cycle the machine to recover. Luckily we were running DRDB (https://www.drbd.org/) and we failed over to the backup machine.

Code: Select all
Backing up sda
Failed to perform backup

Snapshot deadlock detected


We don't have support for this product, but I'm posting the details here in case it's of use to anyone.

The machine is running vanilla Ubuntu 14.04.5 LTS (3.13.0-92-generic #139-Ubuntu SMP Tue Jun 28 20:42:26 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux) and we have DRDB 8.4.4 installed. I don't know if the following has anything to do with the crash, but we have configured DRDB to place it's meta-data onto a loop device. The device points to a file that lives in / on /dev/sda1, which is one of the partions we were trying to backup. So we do:

Code: Select all
 /sbin/losetup /dev/loop0 /drbd-metadata.img


And the DRDB config points to this device:

Code: Select all
resource r0 {
    net {
        shared-secret "xxxxx";
    }

    on drdb-active-01a {
        device    /dev/drbd0;
        disk      /dev/md2;
        address   10.206.4.151:7788;
        flexible-meta-disk /dev/loop0;
    }


Here’s the description of DRDB meta-data.

Below is a snippet from the kernel logs showing the snapshot failure, followed by the first of a number of kernel panic Oops. I can provide the full logs until the machine restart if needed.

Re: Failed to perform backup Snapshot deadlock detected

Veeam Logoby vmniels » Fri Feb 10, 2017 9:40 am

I would advise to contact support in regards to this. DRBD is very sensitive and it might be that due to our snapshot being created it couldn't access the metadata and went into a failover state. Where the source machine still thought it was the main controller and decided to kernel panic in the end. Please post the support case number also for future references.

[MERGED] DRBD support

Veeam Logoby FvdAa » Mon Mar 13, 2017 9:15 am

Running CentOS, but when configuring a DRBD resource, the backup fails every time.

Have been in contact with support, but DRBD isn't supported at this moment. Are there any plans to support DRBD resources?

Hi,

We don't have plans for DRBD support yet, however this may change if we gather a significant amount of requests. Would you please describe the application of DRBD in your particular case?

Thank you

Hi,

we only use DRBD in active/passive setup with LVM underneath it. In those cases we have two servers; one running primary, the other secundairy. In most cases all DRBD resources are primary on one server, but we do have some cases in which we have two servers that have primary/secondary and secondary/primary resources.
