Xen devel - Nov 2012 - .vhd will not boot in VM

We had a XCP 1.5 pool with 2 machines as hosts.  The storage pool which
as NFS mounted lost its ability to export the filesystem with the VM
images on it.

 

We contacted the vendor and we were able to restore it.  However, they
had recommended that we delete the XCP Pool, recreate it, add the hosts
back in, and then mount the storage.

 

That is where we are at now.  We can see the storage and the VM images.
However in XCP Xen Center when looking at the images is clear that the
metadata is lost.  So we can not see which image or snap shot belongs to
which VM.  The names all are blank when we look at the storage.

 

Also, if I randomly mount an image to a VM, it does not boot.  It
produces an error that says:

 

Traceback (most recent call last): - File "/usr/binpygrub", line 808,
in
? - fs = fsimage.open(file,part_offs[0[, bootfsoptions) - IOError:
[Errno 95] Operation not supported.

 

The system kept the VM information as we destroyed the pool and then
created a new one but it looks like we only see snapshots through
XenCenter.  Its like the real .vhd that were running are not showing up.

 

I know it is pretty bad.  We should not have listened to the storage
guys.  

 

Does anyone know someone that can help? 

 

Juan
