This article pointed out problem with authentication http://www.virtualizationadmin.com/articles-tutorials/microsoft-hyper-v-articles/general/diagnosing-live-migration-failures-part2.html

This article resolved the problem http://www.hyper-v.nu/archives/pnoorderijk/2013/03/microsoft-virtual-system-migration-serviceservice-is-missing/

Also, my Active Directory is a bit of a mess so there are multiple security setup that inherited when it should not. Restore to default and unchecked inherited resolve that.

Thank you for the article!

So after the whole Live Migration failure, I have managed to bring it online, as screen shot above. Now all the setting should be set correctly, however it still failed on me when I try to create a VM with 2GB memory. I named it Zeus (stole the idea from the naming server idea).
At this point I am dumbfold and confused. Life as a sole admin is hard.
Helo me MangoLassi, you are my only hope.

The error seems kinda self evident - not enough disk space. How much freespace in the Hyper-V data store is there?

@LAH3385 That error looks like you might have run out of storage at an unexpected place. I know you've probably looked already, but someone has to ask. Do you have 2GB of free space on that C drive?

[LAH3385]

@Dashrender
The cluster storage space is configured with starWind vSAN. I gave it a good 1TB (1,0001GB)

Right, but the error is claiming it's on the system drive.

[LAH3385]

@travisdh1
The VM reside on the cluster drive on C:\clusterstorage\volume1

I might be overlooking this and screwed up somewhere along the way.. but shouldn't C:\clusterstorage\volume1 be a virtual drive? connected by iscsi?

[Dashrender]

Show us the Disk Manager view for your drives, please.

@Dashrender

[Dashrender]

Am I seeing correctly? the CSVFS (Disk 3) is not mounted anywhere?
Maybe this view doesn't actually show mount points that aren't just a drive letter?

[Dashrender]

can we see the output from Mountvol.exe

I found the info at http://thenubbyadmin.com/2012/03/15/listing-all-volume-mount-points-on-a-windows-server/

[LAH3385]

@Dashrender
Now that you mentioned that. somehow the drives on both server (which should be identical) is not.

[LAH3385]

@Dashrender
here is the mountvol.exe result.

[Dashrender]

awww - I think I see the problem.

Your volume on Disk 3 is set to 1 GB, not one TB. You only have 888 Megs free on that volume, and you need 2 GB (2048 MB) free for the RAM disk.

though I'm not sure how you installed Windows into a 1 GB partition.

[Dashrender]

Can you do a details based listing of what is is c:\clusterstorage\volume1?

[LAH3385]

@Dashrender
From your previous message currently I am redoing the whole iscsi and volume clustering. I will report back if the problem resolved.

What I can't tell, is this graphic showing 1.001 GB or 1,001 GB?

Assuming it's showing 1,001 GB (nearly 1 TB of space), this is only showing the whole array, not the the partitions that you created in the array.

We all missed what this graphic is actually showing - it shows that your Cluster Volume is only 1 GB, not 1 TB.

Yep. Comma or period is a big difference all right!
