Backup fails with "Body Timeout Error", "all targets have failed, step: writer.run()"

JB

@christopher-petzel Unfortunately, for me, it still has an error.

@JB Yes makes sense. You are not on the branch that already has the fix. Your commit is latest master branch.
Either switch to the branch that got mentioned or wait for the fix to land in master.

JB

@MajorP93 Ok. Thanks!

@JB @majorp93 We made a smaller PR to be merged just after the release (because it is linked to almost all XAPI calls), the new branch is this one if you want to test: fix_undici_timeout
Same fix, just a little smaller

@pierrebrunet I built on the fix_undici_timeout branch and manually ran the metadata backup job 10 times and did NOT get an error. I will stay on this build through the weekend, let the scheduled metadata backups run, and report back on Monday.

It looks like this is identified and solved, I'll test on a new version of XO next week at some point, but I just wanted to confirm that I've been seeing what appears to be the same problem.

This hasn't affected any of my full, delta or mirror backups, on any of the NFS targets - but it does affect two different Pool metadata & xo config backups. Both on different NFS targets on different schedules.

It's an infrequent failure, sometimes not failing for a couple of days, but sometimes failing up to 3 or 4 times per day - this is on an hourly schedule.

My most recent failure on the hourly job was yesterday morning, the one before that was almost 24 hours earlier.
This is currently on Xen Orchestra, commit 24913 but it was also noticeable on a version from the end of July.

From what I've read, I'm guessing the fix will be in the main branch soon enough and an update will solve it, but if there's any useful information I can provide, please let me know.

Thanks for the feedback so far, folks!

@poddingue On the fix_undici_timeout branch this weekend, all scheduled metadata backups completed sucesfully.

That's great news, thanks, @christopher-petzel !

commit 9cdaf

GregBinSD

Here is my story:
I responded to the notice regarding the latest update of the main branch, Master, commit 9cdaf, by updating the XO-CE vm, rebooting the XO-CE vm, bringing all 3 XCP-ng hosts on line, and then running the XO-CE GUI and selecting Pool Rolling Update.
The rolling update cycled through all 3 hosts in the pool.
I then attempted to run a pool metadata and xo_config backup.
It failed by timing out at 5 minutes.
I decided to shutdown the pool master, so I transferred all VMs to the other 2 hosts and shutdown the master for 15 seconds. I powered on the master, and transferred the VMs back to the master.
I shutdown the other 2 hosts, and then powered them back on. All hosts are indicating "green" status.
At this point I attempted to run the pool metadata and xo_config backup, and it ran successfully.
I waited 2 minutes and ran it again, with success again!
Lastly, I powered down the other 2 hosts, and with the VMs all running on the master, I ran the pool metadata and xo_config backup again, with apparent success.
If someone can tell me the location of the logs that recorded this operation, I will look at them closely to confirm that the pool metadata and xo_config backups actually took place.
Thank you.

Here is the log for the GUI Backup function:
