Quite a lengthy title, I know. Sorry.
Here is what happened (three times now).
I had created a new instance in the Compute Engine in Google Cloud. Server 2012 R2. I added two new drives for data. The first drive formatted and appeared properly. While trying to create a volume on the second drive it gave me an error during the Add access path Task. Said this "Failed to mount path - Invalid Parameter" and the next task - Update cache never completed. What then happened is that the partition type on the first drive I had setup changed to Unknown and was inaccessible.
Since I had no data on it, I just reset both disks and reinitialized them and went on with a furrowed brow. Concerned but thinking I did something goofy. Then later the same thing happened again when I had data on one of the drives and was trying to add a third drive. Same thing. Failed to mount path - Invalid Parameter blows up a different drive on the system.
Now the third time. I had a drive with data on it that existed previously on the first instance and that I had detached and added to a new instance. The drive with data was seen fine on the new instance. When I attempted to initialize the new drive it gave me the same error and the partition type of the good data drive changed to unknown and my data was gone. I detached it immediately and reattached it to the old instance but it was still hosed. I cannot figure out if this is a problem with compute engine or Server 2012 r2. I have worked extensively with 2012 r2 in vsphere and never had a problem like this, ever... I am very skeptical now of the compute engine and wonder if anyone has had this issue. I have looked extensively on the web and can find nothing myself.
Any help would be appreciated as I am supposed to take this server live within a week.
