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

looks like mine also just started working.

Master, commit be960

@JB I'd like to test a different way of investigating the problem. So I won't do it for many people, just send me a private message with a way to SSH to your host and XOA, promise it's not a scam

JB

@marcoi Try doing it three times, and the problem comes back.

marcoi

@JB seems okay after a few back to back runs.

JB

@marcoi Does your backup include METADATA and XO CONFIG?

marcoi

@JB both
Also Xen Orchestra, commit be960

JB

@marcoi The problem is with the METADATA backup. XO Config is working fine!

JB

@marcoi So the problem is with my infrastructure.

JB

@marcoi I see that you use NFS to store the backup. I use SMB.

i switched one of the backups for my extra pool from nfs to smb and its been sitting so i expect it to fail. might be a smb issue. ill update this post with results once it either fails or works

i did test smb and it works.

back to nfs works

Hi! Can you try to replicate on the latest commit?

Hello!
Yes I was able to replicate this issue after updating my Xen Orchestra.

The thing is that the "XO-config-and-pool-metadata" does not always fail.
It fails from time to time then it looks exactly like shown in the screenshot.
Attached logs please find above in my earlier post.

This exact job has been working for a long time before.
After some Xen Orchestra commit this issue got introduced.

I use the same backup remotes for multiple backup jobs.
Only the "XO-config-and-pool-metadata" job is failing with this body timeout error.

@MajorP93 Hi,
Thank you, thank you! I think you found it! It seems to be SMB, @acebmxer can you confirm that you also use smb please?
If this is the case, the bad news is I think we will need to update our docs to not advise SMB at all: it was already said for delta but maybe we will have to extend this to all kind of BR

@pierrebrunet Hello, thank you for working on this issue.

Are you completely sure that this isn't something that got introduced within Xen Orchestra code?

Since I started using XCP-ng / Xen Orchestra I have been using these backup repositories via SMB.
All backup jobs (including this one) have been working fine for almost a year.

This repeated body timeout error is a rather new issue which is why I was wondering if this could have been introduced by XO code changes?

I did not switch to a different linux kernel major version or similar. So the SMB client kernel module is at the same version number.

@pierrebrunet

I use nfs for my remotes and still get the error occasionally.

Edit - Note i am only seeing this error in my work production environment. I am not seeing this issue in my home lab. Both use NFS for remote storage and vm storage.

@pierrebrunet Oh one more thing that I just remembered.
If I recall correctly the first time I saw this issue was right after I patched my XCP-ng hosts without updating Xen Orchestra.
So maybe this is caused by XAPI code changes?
