Lock file is already being held whereas no backup are running.

Hello,

Sometimes, i have on some jobs ( which run every 4 hours ).

Howerver, the previous job is finished in success

Is it possible that has a relation with the mergeWorker of backups which could be running ? if it doesn't finished his operations ?

Example of logs:

xen-orchestra      | 2025-11-27T00:44:43.487Z xo:backups:mergeWorker INFO merge in progress {
xen-orchestra      |   done: 2057,
xen-orchestra      |   parent: '/xo-vm-backups/f37e259d-beaa-7617-e6f1-be814f21e056/vdis/29e0185e-2f67-44d4-bb9e-ee2a772e2543/b09c0230-219f-4ddf-8e19-bfed1464014f/20251126T070610Z.vhd',
xen-orchestra      |   progress: 25,
xen-orchestra      |   total: 8128
xen-orchestra      | }

Is it possible to have this in the XO Tasks sections ? it's interessant to see this.

Best regards

@henri9813 This is 100% related to the merge process still running in the background. I have seen it happen myself.

@flakpyro there is an option to merge synchronously while exporting instead of after the export
in the very bottom of backup job config

it should avoid most of your current merge problems

Hello, @Pilow

Thanks for the tips !

But it would be great to see it in the Task UI to find more easily the trick.

@henri9813 yep merging is totally transparent at this time. can be seen afterward in raw backup logs

you can uncheck the "Merge backups synchronously" in the advanced view of the backup job to have it run inside the backup job, thus making it visible

(we are reworking the internal design for better observability, but there is a lot of job before)
