Restore from backup "iterable is not iterable"

[jcdick1]

XO Server 5.76.0 and XO web 5.78.1 on Ubuntu 20.04

I'm trying to do a restore from a backup of a VM and the log is posting "Iterable is not iterable":

backupNg.importVmBackup

  "sr": "03045d63-88ef-62f4-bf12-e1b65d1b9be3"
}
{

}

Any ideas on how to get my backup to restore?

Thanks!

Hi!

Have you checked this first? https://xen-orchestra.com/docs/community.html

@olivierlambert Hmm ... well, I ran an update to XO, and the versions didn't change, but the upgrade allowed the restore to function. Now, unfortunately, it seems the backup is bad and won't mount /dev/xvda in r/w. Booting to an ISO and running e2fsck reports bad superblocks and can't recover anything. I guess I'll go back one more version and see if the one from the day before is functional before I am forced to just rebuild the server.

What do you mean by running an update? Did you git pull and rebuild?
