Xen Orchestra - Community Edition - Installing with Yarn

Another great place to start with is the troubleshooting template: https://github.com/Jarli01/xenorchestra_installer/blob/master/Troubleshooting.md

Post that last 200 lines, as that error is just repeating. (change 50 to 200)

As another option, you could just restore your snapshop (assuming you made one) and then download the config file and build a new instance and then import the config file.

Hi Dustin -

That's all that journalctl gives me - I assume this is since the last reboot?

The troubleshooting info is pretty much what I've already got - service status is above, I did the git configs after the first update attempt.

/var/log/syslog has this:

Jun 25 13:11:31 xoa systemd[1]: Started Hold until boot process finishes up.
Jun 25 13:11:31 xoa systemd[1141]: xo-server.service: Failed at step CHDIR spawning /usr/local/bin/node: No such file or directory

Jun 25 13:11:31 xoa systemd[1]: xo-server.service: Failed with result 'exit-code'.

Unfortunately no snapshot - I've never had an issue with the updates before, so didn't even think to do so.

Yes, that is correct.

So your only options are to either restore from backup (assuming you were at least making backups) or to build a new instance.

@noelweston do you have your configuration backed up?

noelweston

Yes, I do have a backup... not that recent, but it will do.

Any idea what went wrong?

noelweston

And next dumb question - how do I restore a Xen Orchestra .xva backup into Xen without Xen Orchestra?

No way to know without the logs, did you identify yourself to git as that can cause issues (mostly you won't be able to update).

noelweston

Yes, as above - the first run I got the git "who are you" warning, so I ran the git configs and re-ran the updates.
Which logs do you mean - are there any others I can look at, or do they disappear on a reboot?

the journal logs provide the "best" information as to what went wrong. If you have the update logs (what went by on the screen as you updated) that could provide some insight as well.

noelweston

Ah, OK - no, not any more - again, they went in one of the reboots.
I'll restore the backup (figured that one out), take a snapshot and try again.

You can import it using XenCenter.
Or via command line.

OK, with a backup restored and snapshotted, I re-did the git config and tried the updater again, and it's failed / borked again.

Relevant lines from the log:

Jun 26 10:26:48 xoa systemd[1]: Stopping XO Server...

Jun 26 10:38:06 xoa systemd[1]: Stopped XO Server.

Which is the same as yesterday.

I do have the full build process captured - it's nearly 1200 lines, so it didn't seem like a good plan to upload it straight away. There are no errors that I can see, and the only warning is back to node versions:

warning You are using Node "7.6.0" which is not supported and may encounter bugs or unexpected behavior. Yarn supports the following semver range: "^4.8.0 || ^5.7.0 || ^6.2.2 || >=8.0.0"

Any further thoughts?

Thanks for the help, by the way - much appreciated.

Another update - reverted to the snapshot and ran the updater with -n stable, and got a different set of errors but still a non-starting service...

First error shown is

Any further thoughts?

Node version 7 is depreciated, v 6 is their LTS and 8 is current (8 wasn't working a while ago)

DustinB3403

@noelweston based on the logs, you have a bad version of node. Downgrade to their LTS release.

Danp

My memory could be faulty, but I seem to recall XO requiring a newer version of Node than 7.x. I'm currently at 8.11.1 and not having any issues.

Have you tried to follow the troubleshooting steps listed here?

DustinB3403

@danp the issue we had is that they depreciated a version as we were using version "8" and changed it to LTS. Which iirc they depreciated the number and made an older version their LTS.

Here is the GH issue.

bnrstnr

@danp Looks like I'm on 9.4.0 and not having any problems.

And @DustinB3403 is using an even newer version from the looks of that Github issue.

Though I think we already knew 9 was good lol I'm really good at providing useless information

Danp

@dustinb3403 right, but I seem to recall a separate issue where there was a dependency that required a higher node version. <shrug>
