Backup Error: 302 Found

Danp

Have you tried doing the following?

Edit the backup job
Remove the target remote
Readd the target remote
Save changes

Yep I've edited, removed, and readded the backup job.

I've nuked the xcp-ng install, resinstalled, xcp-ng, created a brand new debain 11 vm, compiled xo from source using latest master, added hosts to the pool, migrated vms to pool.

I've nuked the remote vdev, created a new vdev, added new vdev as new remote, setup a new backup job using new vdev.

I've detached all the hosts and left them in their own pool, used existing and new backup tasks.

The only time backups go through are when the vm is on a master, whether it be in one bit pool or three seperate pools (one for each host). If the vm is on a master it goes... if it isn't... Error: 302 Found

There's a problem with the redirection on the slave host.

@olivierlambert
Any suggestions to try? I had a similar suspicion, leading me to disconenct and reconnect the slave hosts using IP, https://<hostname>, and <hostname>... but all methods result in the same outcome a working pool, but unable to backup an VM on the slave hosts.

Not sure where else to go other than nuking everything and starting from scratch. Which means running backups on everything while the hosts are all masters and then playing 3 card monty with the vms in the process.

First thing is to see if someone can reproduce the issue first

@olivierlambert When I get a bit of time I'll do a bit of a more comprehensive write up outlining initial migration, actions taken, etc in a more cohesive manner. I'll also spin up a few non-critical spare hosts I have on hand and see if I can replicate it or not myself with different equipment.

As it stands now, all the hosts are on their own pool and in the process of running a comprehensive backups for everything to give me a bit of piece of mind. Once that's done, I'll get a bit more aggressive in my efforts!

I was counting on the community to see if someone with a similar setup could report

olivierlambert

Okay we have other reports on this. I wonder if it's a recent change. @julien-f do you want to ask @stucamp to do a bisect to identify the culprit?

@stucamp I finally had time to investigate this, it should now be fixed
