<![CDATA[Backup error with space available]]>I am trying to backup one VM from my XCP-NG to an external 8tb HD. I am seeing the below error with my VM backup.

Start: Apr 20, 2022, 04:03:19 PM
End: Apr 20, 2022, 04:03:27 PM
 EXT-USB 
 transfer 
Start: Apr 20, 2022, 04:03:27 PM
End: Apr 20, 2022, 04:03:56 PM
Duration: a few seconds
Error: ENOSPC: no space left on device, write

The VM is about 8gb in size, and I have only 1.1tb in use out of 3.6tb on my SR. I can successfully snapshot the VM, but the backup fails.

Anyone have any ideas on this?

I'm still not sure why the second one won't restore.

That is correct.

XOA is what I have been trying. I have not tried the restore in community.

edit: when I said try with XOA, I'm not suggesting to pay for it! Just go for the trial, to see if it works there. If it is, it might tell that's a build problem on your side 🙂

I have both installed to try out community. I am performing the restore from XOA, the same console I used for the backups.

Incidentally, I would pay for the XOA, but $70 a month to get back up for my home lab is a bit pricy, I only have one server. You guys might consider offering a paid version with backup that maybe doesn't include premium support for a reduced price. I can't speak for anyone else, but I would be willing to pay for something like that, to have a turnkey solution with easy updates and backup.

In any case, be sure you be entirely up to date (on latest or latest commit)

Any logs inside XCP-NG that I can look at? I've resigned myself to the fact that I will have to rebuild the two VM's that won't import, but I'd like to prevent a similar situation in the future.

Is there anyway to determine whether it's a failed backup or stalled import? Is there anything that can be done to correct a stalled import? I assume there is nothing that can be done for it if it's a failed backup..

Also interesting is that the restores that fail are listed with a number instead of the VM name.

  • It's not a fix, it's just a workaround. It's not normal to have this kind of timeout 😕
  • IMPORT_ERROR_PREMATURE_EOF() means the backup is maybe incomplete or import stalled

I have two that fail to restore and give the error:

    IMPORT_ERROR_PREMATURE_EOF()

    What can I do to determine what this failure means? I found a previous entry about disk space, but I do not have any disk usage issues that I can see.

    Where would the timeout fix be applied in community edition? There is not a /etc/xo-server directory.

    Thanks,

Doesn't matter in terms of hardware, storage, network.

    You can restore all your backup on freshly installed machines or old stuff, regardless what's inside.

So, the next question.

    Is it possible to restore the VM backups to a different install of XCP-NG? I have a single XCP-NG server and would like to re-install XCP-NG and set it up for XCP to be on smaller hard drive and all my VM storage to be on a ZFS RAIDZ1.

I meant to further increase it from the initial solution provided. What happens if you change 1800000 to 3600000?

    Yes, that has been done. The most recent builds Olivierlambert suggested have reduced the issue, just not fixed it completely.
