Hallo,
habe Backup Continuous Replication eingerichtet, das erste voll backup ging durch, das delta Backup aber nur teilweise.
Bei den anderen hängt es seit einem tag. Ist das ein Bug oder wo liegt der Fehler?

ok i try!

I set up Backup Continuous Replication, the first full backup went through, but the delta backup only partially.
Now delta backup hangs. Is this a bug or where is the error?

Are you using XOA or Xen Orchestra from the sources?

yes of course! from https://xen-orchestra.com/docs/from_the_sources.html

Check you are on the latest commit on master, and rebuild. @julien-f might have more to say here. I suspect a bug that we had in a dependency.

what you mean with last commit?

Follow the instructions from that same link to update your install to the latest source, and then retest. It's likely that your issue was resolved in a recent update.

Got the same issue with the last 2 versions i've tested.
I'm now on xo-server 5.57.2

Baker0052

Now testing 5.57.3

Looks like its working with 5.57.3.
Running smooth as expected
3 VMs from Host 1 -> Host2
and 2 VMs from Host2 -> Host1

not hanging anymore

In general, if you have an issue, the first thing to do is to rebuild on latest master commit and try again. If it persists, then it's a non-fixed bug

Also, if you are in production, we strongly recommend to go with XO support!

i have error with delta backup by 3 vm´s:
SR_BACKEND_FAILURE_44(, There is insufficient space, )
What is problem?

There is insufficient space

Seems pretty self explanatory to me. If that isn't the case, then you'll need to provide additional details.

please see screenshots!

@x-rayd Have you checked source SR to see if it is running low on disk space?

x-rayd

I have not done anything!
Today delta backup work perfectly, any ideas?

olivierlambert

Coalesce after snapshot removal (or VDI removal you did), some space we reclaimed automatically.

It was a lack of space on destination SR, your DF Equallogic, probably using thick provisioned.

x-rayd

my Equallogic have 12TB space and only 4.5 TB space is used from continuous replication backup!

olivierlambert

So? As a thick pro SR, every first snapshot will double space needed on the disk size (not space used, total disk size). If you have 4x 2TiB VM disks, a single snapshot of those won't fit.
