VM Protection

[hades]

Hello,

 

I am just experimenting with the VM capabilities of UnRAID 6. I love it, have been waiting for this feature for a while. Now in the process of setting up a new UnRAID configuration because of this.

 

I do have some questions. I set up a VM, and gave it 200GB space, which it promptly allocated to itself, so now there's a 200GB file on the disk. Once I finished with the configuration, I shut the VM down, through Putty I made a backup of the .IMG file onto the array itself, then copied the .IMG file twice (so now I have 1 backup + 3 identical copies). I brought up all 3 VMs, and everything's working fine.

 

This, Putty shows me, is using 800GBs of space. However, when I go into UnRAID's Main tab showing all the array devices, it's only showing 172GB of space used, with 2.83TB free (it's a 3TB disk). Why is this?

 

Also, just to confirm, the IMG files are protected by the array because they are on the array disks (as opposed to cache disks). If the drive fails, I can recover from parity. Correct?

 

Thank you.
