Thank you Vladim, for your response. Ity is greatly appreciated. I will surely read the document. So If I understand correctly, I can try to remove it and if it would be bad for my setup, xe will not do it? :-) I guess coalesce will not work, if one VHD in chain is corrupted. I guess I will have to try and repair it first. We will see. :-)
I vageuly remember that thin provisioning was not possible with CLVM over ISCSI at the time of cluster setup, so I guess we do not have it. Regards, F.
