Error: couldn't instantiate any remote

@JamfoFL What commit is showing under the XO About screen?

Error is likely related to this commit

@Danp Current commit is 3d3b6.

xo-server: 5.103.0
xo-web: 5.104.0

Yes... as I had mentioned, everything worked until I updated yesterday at around 3:50 PM. I noticed there were five different commits that were released yesterday, and the one you linked to is one of those. So, as I figured, one of the commits from yesterday "broke" the ability to run continuous replications.

Now that it looks like you've focused on a cause, I'm sure it's only a matter of time until a new commit is published to fix the issue. Once it's released, I'll get it installed and, hopefully, we can put this behind us.

Thanks!!

Seems that the issue is on the latest version. I had the same issue and rolled back to:

xo-server 5.102.3
xo-web 5.103.0
Xen Orchestra, commit 9d09a

Rolling back fixed the issue. Guess I'll wait a bit for the issue to resolve in a further patch.

@JamfoFL Same issue here, it seems to be a version problem.

Just to be sure: it's when doing BOTH CR and delta backup?

Hello,

We could reproduce it with a job with only continuous replication. the PR with the fix is here : https://github.com/vatesfr/xen-orchestra/pull/6437/files

Can you confirm it fixes the problem ?

Regards
Florent

closed fix(xo-server): fix running replication job #6437

JamfoFL

@olivierlambert No... only with CR. Delta backups still work like a champ!

@florent Thanks for the update, Florent!

Unfortunately, my office is in the direct path of Hurricane Ian, so we are going to be closed for the next day or two, and I won't have an opportunity to try the patch until after we return from the storm!

Hopefully Screame1 (who originally submitted the error) will be able to test and verify, and I will do the same once I am back to the office.

Thanks again for you post, and I'll be sure to update you as soon as I can!

@florent @JamfoFL I'd be happy to try to test. I have changed the source code on my server per the change you made.

That's where my knowledge turns fuzzy. How do I go about compiling that change and trying to run it?

Thanks for the quick response on this issue!

@JamfoFL I've been watching the coverage of Ian from here in Indiana. You and everyone in the path are in my thoughts. Stay safe!

@screame1 You can do something like this:

cd your_folder_where_xo_is
git checkout fix_continuous_replication
git pull -r
yarn
yarn build

(i didn't use XO source since a long time, so maybe i'm wrong ^^)

screame1

@AtaxyaNetwork Thanks! I was able to find instructions in another thread, so I was down the path when you replied. I've applied the patch, restarted the server, and it appears to have started the backup correctly. It will obviously take a few minutes to know if the backups work, but this patch has moved me past the error reported.

Thanks again for the efforts @florent @JamfoFL and @AtaxyaNetwork !

@florent Thanks, patch applied and CR is working now.

JamfoFL

@alcaraz73 @screame1 @AtaxyaNetwork @florent @Danp @olivierlambert I know I'm late back to the party, but just got back into our office after Hurricane Ian. Thanks to all for your well wishes... I was very fortunate to come out with no damage, and was only without power for about 12 hours.

Now that I'm back, I also applied the fixes here (and updated to the latest commit) and can confirm continuous replication is working like a champ.

Thanks to everyone involved for the help!

Oh wow, you were lucky indeed!

Happy to know you are safe
