The support tunnel has been created.

Do not stop this command before the intervention is over!
Give this id to the support: 41699

Thanks, we'll take a look when we can

@polyaks FYI, it looks like a corrupted (truncated) file issue.

You can take a look at this post where I explain succinctly how to check XO backup files

@olivierlambert
"Expected values to be strictly equal: 430 !== 512" is not the result of using a GFS2 drive.
On an XOA (non-source) server, the delta backup on the GFS2 drive completed with a successful result

Clarification
During the backup process, I can edit and crate Backup tasks, only to display information about VMs and SRs I need to wait about 5 minutes.

Delta will fail as soon you'll make a delta. So only the first delta backup on GFS2 will work. Not any other.

See https://xen-orchestra.com/docs/delta_backups.html#continuous for how it works.

@olivierlambert
I was able to reproduce the problem on the lastest XOA server.
Give this id to the Support tunnel : 41699

Backup Task settings:

XOA work correct if vCPU settings are 1socket= 1 core

If I change vCPU to 1 socket = 2 cores or 1socket= 4 core

Received error when starting the same task

As I said, it's normal you can't do delta on GFS2. It's not possible, technically speaking, because GFS2 is using a storage stack that doesn't support delta

@olivierlambert
I run the same task all the time without any changes.
How is it determined that the task must be run as full or as a delta?

Have you read https://xen-orchestra.com/docs/delta_backups.html ?

Use normal backup it will work. Or stick with delta and advanced option, a full every 1 backup.
