Today I had a power outage and switches went out. This for some reason caused my cluster to freak out (something to look into later) and one of my VMs did not start back up. After looking into why it would not start up I found that the BIN and VSV file located in the GUID folder for the VM under my CSV in the Virtual Machines folder was just missing! The GUID folder for the VM still exists but the folder is cleaned out and the BIN and VSV files (2 total) are gone!!
Currently, I do not have any snapshots of the VM at this point. It's something I was about to start doing for all my VMs on a scheduled base but have not gotten around to it yet.
What has happened here? Where did they go? Is there any way to get this back?
When I try to bring the VM online from the Failover Cluster Manager I get the following error...
Cluster resource 'Virtual Machine SERVER01' of type 'Virtual Machine' in clustered role 'SERVER01' failed. The error code was '0x2' ('The system cannot find the file specified.').
Based on the failure policies for the resource and role, the cluster service may try to bring the resource online on this node or move the group to another node of the cluster and then restart it. Check the resource and group state using Failover Cluster Manager or the Get-ClusterResource Windows PowerShell cmdlet.
I also run a Cluster Validation and currently I'm running through the report that has just finished. I'm hoping that will lead me in the right direction but wanted to ask here hoping it might be a simple fix.
This seems to be the issue but I'm not sure how to find out what LUN was used in the past to select it again...
OK I tracked it down to it being 1 of 2 disks and I'm not sure which one it should be. This would really be a question about either
Cluster Shared Volumes and/or
Cluster Quorums. I need to know which one of these might be attached to a file server as a resource? I'm not sure if both of these just "float" from cluster node to cluster node as needed or if maybe the QUORUM drive needs to be hosted by a file server etc.. Can someone maybe tell me which one of these drives might more likely be connected as a resource to my file server?
Currently it looks as if all VMs have the CSV drive (where all the VMs are kept) as a resource so I'm guessing it's not the CSV drive that I need to add back to my file server and that drive might just "float" in the cluster (for lack of a better term). Seeing as how CSV works with all nodes having a
C:\ClusterStorage\Volume1 on the host nodes at the same time, my money is on the QUORUM.
Can someone maybe confirm my logic (or attack it) please?
