Hyper-V Failover Live Migration failed. Error 21502

[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/

@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.

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

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!

[LAH3385]

@Dashrender

LOL!!!! I am pretty sure it is a comma

Drat, you quoted me before I corrected my post - please see correction.

Yeah, so the Cluster Volume is fine, it's the partition on the cluster that's to small.

[LAH3385]

@Dashrender
Actually you were right! Not with the comma part, but the problem is I gave it 1TB size but linked it to 1GB partition. I didn't show the resource down belong it it only show 883MB out of 1GB

Now it pointed to 1TB partition so it is working now.

[Dashrender]

Yeah, when MS stopped showing a real size comparison of partitions vs the whole volume, it became even more important to full read the stats, not just trust the graphic. If the graphic would have shown this tiny slice it would have been obvious that the slice was to small to use.

[Dashrender]

So considering that.. where was your VM actually sitting? How large is/was your VM?

[LAH3385]

@Dashrender
currently 125GB (starting size) on Disk 3 of 1TB.

[Dashrender]

You were trying to do live migrations before - and it seemed like you had at least limited success - I'm wondering where the VM files where and how that happened?

[LAH3385]

@Dashrender
previously it failed because of Kerboros credential. After giving it delegate rights the live migration works.

even though the storage space was to small?

[LAH3385]

@Dashrender
yes. but previously I set it with 512MB which fit into the 1GB storage
