[one-users] VMs not deploying because of datastore error

[Javier]

Hi Ruben,

Thank you for your reply. Here it is what I found out:

1- I had a cluster defined but I deleted it, so right now I don't have any.

2- The only host I have at the moment is correctly monitored. And the 
output of monitor_ds.sh is correctly showing info about the datastore (I 
cannot run anything else from the script because I don't have root 
privileges):

DS_LOCATION_USED_MB=34417
DS_LOCATION_TOTAL_MB=32802826
DS_LOCATION_FREE_MB=18826318

However OpenNebula is not monitoring datastore 0 as it does with the others.

3- I haven't set DATASTORE_LOCATION. I have a self-contained 
installation and it should default to $ONE_LOCATION/var/datastores, 
which resides in a network shared partition. And yes, the datastore is 
mounted.

Regards,

Javier
