[one-users] Deployment files transfer error

Tue Sep 30 00:29:20 PDT 2014

Hi Manuel,

Could you provide more information like the output of `ls –la /var/lib/one/` command?

I suppose the problem might be related to idmapd configuration. I guess you will see all the files owned by ‘nobody:nogroup’. In that case Google is your friend.

Hello again,

In order to share data between the host with the frontend and the target hosts, I followed the guide at http://docs.opennebula.org/4.6/design_and_installation/quick_starts/qs_ubuntu_kvm.html .

Mainly, I've exported the directory /var/lib/one in the frontend with NFS:

/var/lib/one/ *(rw,sync,no_subtree_check,root_squash) (in /etc/exports)

and I mounted the same directory in the host:

10.12.0.15:/var/lib/one/  /var/lib/one/  nfs   soft,intr,rsize=8192,wsize=8192,noauto (in /etc/fstab)

Now, the directory /var/lib/one in the host has a more typical structure but I cannot access /var/lib/one/.ssh even with the root user. It throws a permission denied message.

Any ideas?

Thank you very much,

Best regards

Hi Manuel,

I’m not familiar with the slave zones, so I don’t know what will be the result of mounting the /var/lib/one in them. But you can always export only the needed datastore and mount it to /var/lib/one/datastores/$datastore_id on the target host.

Good morning,

I've deployed another VM because I deleted the other one. Anyway, the error is the same:

Command execution fail: /var/lib/one/remotes/tm/shared/clone opennebula-worker15:/var/lib/one//datastores/1/2ac54ee0c7b5f0f489216e9a04451725 10.12.0.18:/var/lib/one//datastores/0/18/disk.0 18 1

In the target host, the directory /var/lib/one/datastores/0/18/ is empty.

Do i have to configure /var/lib/one/ in the target hosts as a NFS directory?

Thank you very much

Best regards

Hi Manuel,
you are obviously using shared datastores. Can you check that you can access the file 'var/lib/one//datastores/1/2ac54ee0c7b5f0f489216e9a04451725' on the target hosts?

Good morning,

I have four hosts and I installed OpenNebula in one of them. That installation of ONE is a slave zone.

I added the four hosts and I can deploy VMs in the one where ONE slave is installed but in the other ones I can't.

It must be some issue related with the files transfer during the deployment, because the errors in the log are:

I can do ssh between nodes without putting the key.

Thank you very much for your help. Best regards
