[one-users] Problem starting VM over a SSH system datastore

[Campbell, Bill]

It looks like it's attempting to use the 'shared' TM driver to copy from Datastore ID 1 to ID 109 (which will fail as this is attempting to copy over on the remote host, where the '1' datastore doesn't exist). 

Can you validate that the default datastore (ID 1) is set to be an 'SSH' datastore as well? I think that may be where it's picking up how it's supposed to transfer the image. Datastore 109 is your system datastore for the cluster GPOD, which would explain why it's attempting to copy to that 109 directory.

Subject: [one-users] Problem starting VM over a SSH system datastore 

Hello everyone, 

I'm deploying my first cloud with ONE 4.4 and I'm facing a problem that I don't understand. I have read all the related guides and I though I had understand them but obviously it's not the case. 
My problem is that after creating a SSH System datastore to just copy the VM images from the frontend to the hosts, every time I try to start a virtual machine I end up with the following error messages in the log: 


Tue Dec 10 12:10:47 2013 [TM][I]: Command execution fail: /var/lib/one/remotes/tm/shared/clone gpodmc.smos.lan:/var/lib/one//datastores/1/91209cfc6a24a39e60b42d9cd6ae5d7f dpgsrcorepfw-3.smos.lan:/datastore/109/8/disk.0 8 1

The DATASTORE_LOCATION is pointing to "/datastore" 

This is the output of the "onedatastore show" command:

[oneadmin at gpodmc one]$ onedatastore show 109

What I really dont't understand is why ONE is trying to access the source image from 

/datastore/1/91209cfc6a24a39e60b42d9cd6ae5d7f /datastore/109/8/disk.0 

instead of using 

/var/lib/one/datastores/1/91209cfc6a24a39e60b42d9cd6ae5d7f /datastore/109/8/disk.0 
? 

Any body could explain to me what I'm doing wrong, please? 

Regards 
Fernando
