Hello,
I upgrade our opennebula kvm cluster from 5.6.1 to 5.8.1 following the notes from here http://docs.opennebula.org/5.8/intro_release_notes/upgrades/upgrade_56.html
Everything was fine up to the the " Update the Drivers" and the sync command.
$ onehost sync
Failed to update the following hosts:
The --force option gives me the same result.
The cluster is working fin for now, but I am worried because the sync did not complete.
Hi Georgi,
I am almost permanently playing with the files in the remotes folder and usually the such issue usually caused by wrong file permission/
The issue should become clear if you run
su - oneadmin
scp -rp /var/lib/one/remotes/* $REMOTE_HOST:/var/tmp/one`
and look for Permission denied
Cheers,
Anton Todorov
Hello,
@ahuertas
Did you see any error message in the oned.log?
No, there is nothing in the logs related to that command.
such issue usually caused by wrong file permission/
Yep, that was the case.
I checked the permissions. The only file inside /var/tmp/one that was not owned by oneadmin was reserved.sh . I changed the owner and the sync was successful.
Thanks!
It will be much better if the output from onehost sync can be more verbose.

Will review the install procedure of addon-storpool to address the issue.
Best Regards,
