XO task watcher issue/CR broken

[Andrew]

julien-f node.js v18.14.0 on Debian 11.6

[julien-f]

Andrew What kind of remote are you using? And with which configuration (encryption, multiple data blocks, etc)?

[julien-f]

My bad, there is no remote with CR

I have no idea what's going though…

[Andrew]

julien-f I was just going to say it's another host local storage, not a remote. Desination host is not in the same pool but is on the same 10GB LAN. All hosts are 8.2.1.

[julien-f]

Andrew I'm unable to reproduce on my end

If you can reproduce with an official XOA, open a support tunnel and I'll investigate further.

[Andrew]

julien-f I loaded XOA (5.109.0) but it's not new enough to include to problematic code that cause problems in XO source.

[julien-f]

Andrew If you open a support tunnel, I can deploy a sources XO in your appliance.

[Andrew]

julien-f ok.

[julien-f]

Andrew Please test the branch cr-issue and tell me if that helps.

[Andrew]

julien-f cr-issue branch commit 27d81 resolved this new CR problem for me. Thanks!

[julien-f]

Andrew I need to understand why it's working now

Which version of XCP-ng/XenServer are you using as source and as the target of the CR?

[Gheppy]

This commit 27d81 is working for me to.
XCP-ng is 8.2.1, up to date

[julien-f]

Andrew & Gheppy: I've just pushed a new commit in the cr-issue branch which adds some debug logs, it adds something like that:

putResource(b1imtu1j0y): taskRef: OpaqueRef:10eb89fd-d31e-495b-955d-672c61a4ea48
putResource(b1imtu1j0y): useHack: false
putResource(b1imtu1j0y): body#end
putResource(b1imtu1j0y): request#unpipe
putResource(b1imtu1j0y): request#prefinish
putResource(b1imtu1j0y): request#finish
putResource(b1imtu1j0y): response#resume
putResource(b1imtu1j0y): body#close
putResource(b1imtu1j0y): response#readable
putResource(b1imtu1j0y): response#end
putResource(b1imtu1j0y): response#close
putResource(b1imtu1j0y): request#close

If you could try it and show me the output, that would help me understand what's going on

[olivierlambert]

Eager to read the output, it's weird we can't reproduce here, there's something

[julien-f]

Gheppy Could you please include all the logs up to the taskRef entry?

[Andrew]

julien-f Hosts are XCP 8.2.1 and updated.

Here's the logs... It did suppress 373874 messages... only 417267 left...

rename output.txt as output.txt.gz and uncompress.

output.txt

[julien-f]

Andrew Thank you, I just pushed a new commit in which I suppressed the drain event

[julien-f]

Once filtered, here's what I see:

putResource(hhprvsf5i): taskRef: OpaqueRef:bb9bbc77-8c88-4621-82a7-745197306c3b
putResource(hhprvsf5i): useHack: false

putResource(hhprvsf5i): request#unpipe
putResource(hhprvsf5i): body#error

putResource(hhprvsf5i): body#close
putResource(hhprvsf5i): response#resume
putResource(hhprvsf5i): response#end
putResource(hhprvsf5i): response#close

I don't understand why there is not a request#finish event like in my test

[julien-f]

It's probably related to the body#error event.

I will add more debug and will keep you posted when the branch is ready.
