[one-users] [Datastores] Image Datastore has no size

Okay so I tried a few several things,
I can launch those commands on the ESX host, however, when I login with oneadmin it seems to automatically get in root mode. Plus the ESX system does not know the commands “whoami” nor “sudo”. (My BASE_PATH is /vmfs/volumes btw).

I checked oned.log back, still no errors : [cid:image004.png at 01CF5EF0.67FADED0]
Then, following this discussion here : http://comments.gmane.org/gmane.comp.distributed.opennebula.user/13872
I tried to change the type of the Image Datastore to SYSTEM_DS, and it actually got monitored properly, with a 19,2G size. Changing it back to IMAGE_DS recreated the issue. “$ onehost sync” didn’t solved the problem.
Also, creation of any kind of datastores doesn’t seems to work neither : no dir is created in /var/lib/one/datastore following the “onedatastore create tmp_file” command, and new datastores are displayed with zero capacity value too.
By the way, I have another question, my datastores are nfs exported, and originally created on a VM volume (/var) that has a 20Gig capacity. So how comes does Files Datastore display a 19.2Giga capacity and System Datastore also display a 19.2Giga capacity ? They do physically use the same disk space right ? (even if its a VM virtual disk). I followed the quick start guide correctly, however there still are some blured line about storage for me.
Thanks you for your time

The information is gathered by /var/lib/one/remotes/datastore/vmfs/monitor. Can you check that /vmfs/datastores/1 exists at 172.20.10.12 and that oneadmin can excute
du -sLm /vmfs/datastores/1
df -m
Cheers

Hi Ruben
SSH is fine between the two, oneadmin can login without password.
No errors in /var/log/one/oned.log neither. Maybe there is a way to resize the datastore manually ?
Also, same problem occurs when I try to create a new datastore : no capacity at all.

Hi
Can you check oned.log? May be the front-end cannot access 172.20.10.12 through ssh?
Cheers

Hi everyone.
I can’t possibly upload an image to OpenNebula because my Image Datastore size is non-existent (not empty, non-existent, like 0MB).
I’m new to OpenNebula and installed it by following the QuickStart guide for WMware : http://docs.opennebula.org/4.4/design_and_installation/quick_starts/qs_centos_vmware.html
Here is the configuration of the two datastores I created :
Datastore 0
SHARED YES
BASE_PATH /vmfs/volumes
TYPE SYSTEM_DS
TM_MAD vmfs
Datastore 1
LN_TARGET NONE
BASE_PATH /vmfs/volumes
TYPE IMAGE_DS
DS_MAD vmfs
CLONE_TARGET SYSTEM
DISK_TYPE FILE
BRIDGE_LIST 172.20.10.12
TM_MAD vmfs
Here is a screencap from sunstone Dashboard:
[cid:image005.jpg at 01CF5EED.B9702BB0]
As you can see it is showing a third datastore named “file” with filesystem type. I can’t, however, upload anything on that one because the wizard in the Create Image section won’t let me choose any other datastores than the “defaults” one, which is the Image one, and has no space at all.
On the ESX host, the DataStores are mounted and seems to be working fine :
[cid:image006.png at 01CF5EED.B9702BB0]
I tried to upload and .iso via ESX on Datastore “1”. That worked, but in opennebula display it has being placed on the datastore 2 (as you can see on the previous screencap, there is a 2.2GB space used on datastore 2).
Therefore I think there might be a confusion between the Image & Files Datastores in OpenNebula.
Any idea of what could be the roots of the problem ? And besides that, how could I solve this ? Should I recreate new datastores, and mount them on the ESX? If yes, how should I proceed ?
Thanks in advance for your help.
