backup failed

Danp

@joearnon Not what I was expecting. Maybe it's different on Debian. <shrug> Did you use a script to install XO? If so, which one?

Hello everyone,

I ran into the same problem. I had the xo-server rebuilt using a force rebuild. Without effect.

Information about Xen Orchestra:

xo-server 5.79.5
xo-web 5.82.0
nodejs v14.17.1

Xen Orchestra says:

Error: all taget have failed, step: writer.beforeBackup()

The output of "journalctl -u xo-server -f -n 50" can you see below:

Jun 17 11:51:52 xoce xo-server[2210]:   },

For all VMs it is the same output so i copied it only once

A commit fixed that very recently. Please rebuild on latest master commit, as you should do anytime you have a problem

Black_Sam

@olivierlambert

I'm on

Updated commit 9a8138d07bc1a5f457ebcb4bbff83cd07cda80ed 2021-06-17 11:56:04 +0200

I think this is the master commit!?

and the problem still is there...

olivierlambert

It's indeed the last one. Are you sure it's properly rebuilt?

Anyway, that might be something else. @julien-f any idea?

Black_Sam

@olivierlambert

I'm sure I did a complete rebuild.

Danp

@olivierlambert @julien-f

FWIW, I have also started having this same issue after updating to the latest sources.

Here are some details --

Commit d44509b2cd394e3a38dc4ba392cc54dd2f50e89f  Working backing
Commit 56e4847b6bb85da8ae2dc09e8e9fb7a0db36070a Missing writer issue
Commit 9a8138d07bc1a5f457ebcb4bbff83cd07cda80ed all targets have failed, step: writer.beforeBackup()

julien-f

Thank you all, I'm investigating.

julien-f

Should be fixed, sorry for this

Thanks all for your feedback!

Black_Sam

@julien-f

a full backup of my VMs is in progress ... if any issues arise i will post it here. Thank you for your commitment! That is awesome!

JoeArnon

@julien-f
Thanks a lot julien

Black_Sam

@julien-f

The backup breaks off at approx. 44-45% with the error mentioned above ...

If that should be a new thread just give a decision then I'll open a new one.

julien-f

@black_sam Please makes sure that you are using the latest xen-api lib. Also, this might be a XCP-ng/XenServer issues, please check your host's logs. Out of curiosity, are you using compression in your backup job?

Black_Sam

@julien-f

xcp-ng 8.2.0 is fully patched so ist should be up to date.
I didn't setup any compression options. I only configurated the backup jobs over xen orchestra

€dit:
hmmm... I think it was a problem with my network... after shifting the host into an other subnet without VLAN the backup finshed without any issue.

Thank you for your support

julien-f

@black_sam Thanks for your feedback
