Re: NFS in multiple VM servers

2012-02-20 Thread Andy Kurth
I made some updates to the following page:
https://cwiki.apache.org/confluence/display/VCL/VMware+Configuration

See the Network Storage Only - No Repository example at the bottom.
I think this is close to your environment.

 Hi Al,

 I'm assuming that you're mounting the NFS shares on ESXi hosts, and using
 those shares as the datastores for the 8 VM hosts.

 If you're using local storage as the VM host profile, the the management
 node retrieves the requested image from a centralized location, copies it to
 the VM host, and then starts that image up on the target host.  In this set
 up, the management node is the component of VCL that needs to be aware of
 the location of the image repository.

 If you're using network storage as the VM host profile, the images are NOT
 captured to the management node's repository path during image capture.  It
 assumes all the hosts are using the same network storage.  It sounds like
 this might be your current setting.

 Check out the VM Disk parameter in the virtual host profile (scroll about
 4/5 down):
 https://cwiki.apache.org/confluence/display/VCL/VMware+Configuration

 Check which VM host profile you're using:

 Click Virtual Hosts
 Select one of your 8 VM hosts from the pull-down
 Click Configure Host
 The current VM host profile is shown below

 Check where the management node is expecting images to be located:

 Click Management Nodes
 Click Submit (edit management node information)
 Click the Edit button next to a management node
 Check what's in the Install Path box

 Regards,
 Mike

 Hello,

 Having a bit of a problem, and I guess it might be an assumption that I am
 making…

 I have 8 VM servers on VCL. Each server is attached to NFS disks. These
 are separate NFS shares for each VM server.
 I capture a base image on one server. I can reload any computer attached
 to that server with that image. That part is ok.

 The trouble comes when I try to reload a computer attached to a different
 VM server. VCL complains that it cant find the base image.

 I was under the impression that VCL knew where the base image resides, and
 transfers it to the host computer.
 At least, that was what the info under pending said it was doing.

 So, my question is…

 Do the NFS shares for multiple VM servers need to be the same mount point
 ?
 Can't I have VCL find the base image on whatever VM server it was created
 ?

 Thanks,
