This is from /var/log/messages of the combined node:

I believe you meant ‘journalctl -u opennebula’ ☺ which in fact shows more info

Am I right in assuming that the permission denied error seems to be from the front-end to the drbd node?

Thanks in advance

Not much here to see a reason, please also check `systemctl -u opennebula`

I am receiving the below when uploading or downloading images to the image datastore. If I create a datablock in the same image datastore it completes successfully. Is this a permission issue or am I missing some configuration?

This happens after the download has completed and in oned.log I can see the below entries:
