Backup jobs run twice after upgrade to 5.76.2

karlisi

Right now one of my CR jobs are stuck, symptoms are the same as with XO from sources.
XOA 5.43.2 (xo-server and xo-web 5.56.2)
Hosts where VM is running and where it is replicated to, both XenServer 7.0

Perhaps there is something with my environment but then why it is working with older XO versions.

There is probably a problem in XO regarding this because we have received multiple similar reports, we are investigating.

julien-f

@karlisi I've been unable to reproduce the issue so far, can you tell me which version of XO has the issue and which one does not?

Also, if you could provide me with your job configuration it would be nice

Can I send it to you in PM?

olivierlambert

In this case, it's better that you open a ticket on xen-orchestra.com

@olivierlambert Done

Thanks a lot for this great ticket with all the context, this is really helpful!

Hi,

I can give a little update on our issues, but our 'workaround' is really time consuming.

Besides the problem of randomly stuck CR jobs, which could be fixed mostly by:

stop xo-server/ start xo-server (sometimes needed to restart xo-vm) and restart the interrupted jobs again and again until all VM are successfully backed up.

Now without changing anything the jobs are again started twice again most of the time, but not always.

I can not find a correlation to this.

Somehow it looked that this could be fixed by dis/enabling the backup jobs, but as of now this doesn't make any difference.

@tts Are You on latest XOA version?

tts

It wasn't XOA, we used xo-server from sources.

I planned to test with XOA but Olivier yesterday wrote that it's probably fixed upstream.

So I updated our installation to xo-server 5.57.3 / xo-web 5.57.1 and will see if it's fixed.

fingers crossed

Maybe there are additional problems. I just noticed one of our rolling-snapshot task started twice again.

This time it's even more weird, both jobs are listed as successfull.

The first job displays just nothing in the detail window:

json:

{
  "data": {
    "mode": "full",
    "reportWhen": "failure"
  },
  "id": "1583917200011",

  "start": 1583917200011,
  "status": "success",
  "end": 1583917207066
}

The second job shows 4? VMs but only consists of one VM which failed, but is displayed as successful

    }
  ],

}

So the results are clearly wrong, job is ran twice, this time at the same point in time.

Would it help to delete and recreate all of the backup jobs?
What extra information I could offer to get this issue fixed?

Already thinking about setting up another new xo-server from scratch now.

please help and advice,
thanks Toni

olivierlambert

Please try with XOA and report if you have the same problem.

tts

I'm currently on it, we did setup the XOA appliance recently. Just needs activating the trial phase, I think I can do that today in a few hours.

Can we import the settings safely from our current 'from sources' version or do we need to setup everything from scratch?

olivierlambert

Yes you can import settings in XOA.

tts

Ok thanks, will do that and report back later.

tts

Looks like XOA on stable channel is only updating to v5.43.2,

I really don't get the point why 'rolling back' to a much older version could help solve the backup problems in the more recent version 'from sources' 5.56+?

Is this a completely different codebase?

Quite lost now!

olivierlambert

XOA got its own numbering, unrelated to xo-server or xo-web: it'a all a matter of a coherent "whole", including dependencies etc. Thing we can't provide when built on sources.

Please test and report You can switch to latest too, doesn't matter.
