Followup on post: https://xcp-ng.org/forum/topic/9215/backups-started-failing-error-vdi-must-be-free-or-attached-to-exactly-one-vm

Upgraded to latest build and tried backups. Now ALL VM's failed with this error:

And I got dozens of hung tasks:

It's getting from bad to worse

[manilx]

@manilx Had to reboot my hosts to get rid of the hung tasks....

@manilx Yesterday evening I installed latest build. Retried my backups and still got this error on all my VM's.

Apart from the hung tasks.

Disabling the NBD option makes the backup work. So the new CBD (or what it was) option breaks our backups with NBD.

I guess implementing new features shoud not break old ones especially backups......

You are using XO from the sources, so this can happen by definition. If you want something that doesn't break for production, please use XOA We'll do our best to avoid breaking master, but again, there's no guarantee.

[manilx]

@olivierlambert True. Will have to refrain from updating each week. And keep working versions as long as they work

[olivierlambert]

That's also a dangerous strategy, since we fix security issues and bugs on a recent basis. But yeah, it's up to you to find the right timing. If it's production, I really suggest to go for XOA though…

[manilx]

@olivierlambert Using XOA in production obviously (https://xcp-ng.org/blog/2023/05/15/leading-the-pack-mani-industrias-plasticas-sa-journey-with-vates/)

But here on my homelab where I test before deploying (8.3 etc, apart from running my home stuff coming from proxmox) I can't justify the cost

[olivierlambert]

Oh sorry didn't catch the nickname For your QA/test, then it's fine @florent is away this week, so we'll have to wait for him to get back and fix it

[manilx]

@olivierlambert No harm done! Yes, looking forward to bug fix and test. It's actually the only "serious" issue I've found, running 8.3 since beta 2 came out.....

[olivierlambert]

Hi,

We added 2 fixes in latest commit on master, please restart your XAPI (to clear all tasks), and try again with your updated XO

[manilx]

@olivierlambert Still broken:

Please don't repost on all threads

[manilx]

@olivierlambert sorry!
