[one-users] Xen with NFS..

[Pallab Chakrabarty]

Hi,

 

 

The problem lies in these two lines:

 

 

Line1:

=====

Thu Aug 20 12:25:55 2009 [VMM][I]: Generating deployment file:
/opt/cloud/var/36/deployment.0

 

Line2:

=====

Thu Aug 20 12:25:55 2009 [VMM][I]: Command execution fail: 'cat >
/opt/cloud/one/var/36/images/deployment.0 && sudo /usr/sbin/xm create
/opt/cloud/one/var/36/images/deployment.0 && sudo /usr/sbin/xm sched-cred
-d one-36 -w 256'

 

 

 

This is clear that:  

 

1) deployment file is generated at loca: /opt/cloud/var/36/deployment.0

 

2) but cat > command looks for a different location:   'cat >
/opt/cloud/one/var/36/images/deployment.0 

 

 

/images/ ???

 

Pls note, VM_DIR is defined correctly as per the documentations..

 

 

Kindly advice further ..

 

 

 

- regards 

   Pallab

The problem here is that it can not create

/opt/cloud/one/var/36/images/deployment.0 in the execution host. The

command that starts with "cat" is executed in the execution host, not

in the frontend. The most probable cause of this error is that

/opt/cloud/one/var/36/images does not exist in the execution host.

What is the shared directory between nodes and what is the mount point

in that execution node? If not specified otherwise (VM_DIR variable in

one.conf) OpenNebula expects its var path in the same place in

frontend and execution nodes.

 

Bye
