Hi @HolgiB - we have all our different cloud init files in a git repository plus the network files with the static ip configuration for the virtual machines, so we can track every change and have the configs handy instantly. I do changes in my IDE and copy the content of the file to xo when i install a new machine. Maybe that helps you with your workflow and makes it easier to edit and deploy. Cheers Ringo

@olivierlambert or @pdonias did u find any time to look into that problem? cheers Ringo

@olivierlambert thanks! for the info @pdonias do you have any idea what could be wrong? cheers Ringo

@olivierlambert sadly that didn't help

Hi everyone, I have a strange problem. I updated our XO from sources last week, and now LDAP auth is not working anymore

Interesting part is: when I try it on CLI it works

But in the web interface with the same configuration, I get an error

}

any ideas what could be the problem?

@florent Thanks for the Tip!

The risk of an infinite delta and losing the backup chain if something goes wrong is a bit too high I bet if something goes wrong exactly in that moment, we need a reliable backup chain

Sadly, we do not have "cheaper" storage for mirror backup, as it's only a small setup for a small company.

This situation is a bit of a pickle if you want one full backup on a certain day, plus deltas, but not two full backups all the time

Is there any chance that this will change in the future to make that situation happen?

@Danp very interesting! Thank you! So is it somehow possible that we only do full-backups on Saturday night and only have one fullbackup? Our backup storage is almost full, and we need to make some space, so getting rid of double full backups would be great cheers Ringo

Hi everyone

we have a strange behaviour at the moment, we have a delta backup job configured like that:

• Full backup interval is 0 as we want full backups only on Saturday night
• We have one schedule for Sunday to Friday night with no forced full backup for incremental backups
• We have one schedule for Saturday with Force Fullbackup enabled to make sure only Saturday is the full backup

Screenshot 2025-04-15 at 21.29.47.png

So, now problem is we have two full backups on our remote, and we are getting into storage space trouble

Screenshot 2025-04-15 at 15.11.58.png

Has anybody an idea why this is happening? What do I miss?

cheers and have a great day!
Ringo

@astrugatch you can put it into the same files like the cert it’s called a chain cert then

@julien-f thanks! I have tested it and its working now! cheers Ringo

@julien-f happy to help let me know when you fixed it and I will test it. cheers Ringo

hi everyone,

I am on the last version of XO and wanted to play around with the REST-AP. scheduling a rolling pool update but I got an error I can't figure out:

curl -X POST -b authenticationToken=XXX https://xo.xxx/rest/v0/pools/5222b44b-e25b-a14d-4da2-c7a0dd8cf59f/actions/rolling_update
/rest/v0/tasks/0m1agafzh

the log says:

  }
}

Do you have any idea what the problem is here?

If I start the update via XO everything works without errors.

thanks and have a great day!
cheers Ringo

@Studmuffn1134 No we shutdown virtual machines first and xcp-ng servers last.
Puppet is a config-mgmt tool so you don't have to install apcupsd on every machine manually, it can automates stuff like that.
what do you use as nfs storage? normally you can configure to a shared network storage device that it talks to the smart-ups and shuts it self down before its running out of power

cheers Ringo

We installed apcupsd in every virtual machine with puppet and shut down test/dev systems early and important systems later. XCP-ng servers also got it installed and shutdown last.

@jedimarcus thank you i will have a look!

hi team,

we were wondering, is it possible to get the usage of the SRs of a pool from the xoa API so we could monitor it?
also is there a list somewhere online of what information we can get from the xoa API at the moment? I don't want to bother you with my questions all the time, easier to check what's possible

cheers, Ringo

@julien-f @olivierlambert thanks guys I will wait until the end of the month you rock!

hi team, thanks for your excellent work! we love xcp-ng and xoa
I've written an ansible playbook to update our virtual machines and I would like to trigger a snapshot of the VM bevor I start the automatic update. is there a way to trigger that snapshot through the rest API? I've searched a bit in documentation and the forum but couldn't find something
cheers Ringo

Thanks guys! Absolut Legends

@julien-f thanks for the answer! this will get overwritten with every xo source update right? how about a licensed xoa? cheers Ringo
