Just did all that. Worked successfully! Thanks so much man, I never would have figured that out on my own! I guess I can delete any duplicate vdisk in /cache/domains now? (backups are stored elsewhere)

Thanks for this. Sorry it took me so long to try it, as work kept me busy. Here's the output from all commands. Seems to have worked successfully. What do I do now? How do I point the VM correctly? Anything else I need to do?

Ok thanks for being thorough. Here's the output for the commands: For my own education, can you please explain what they did?

I can't see in the docs how to do this. There is no longer a 'snapshots' icon to click on in the VM, even when it's not running. Can you please explain, step by step? I have no idea what I'm doing.

Anyone?

I've changed the first 'source file' from the screenshot above from /mnt/vdiskpool/domains/Windows 11/vdisk1.provisionedqcow2 to /mnt/vdiskpool/domains/Windows 11/vdisk1.qcow2, and now it deletes any mention of the cache directory. HOWEVER, what you said about losing the snapshot and not the data was wrong - it's actually an older state of my VM from a few months ago when I created the snapshot. I lost months of data on this. I could restore the vdisk1.provisionedqcow2 file, but then I'm back to square 1. Is there a way to retain the latest version of the VM while killing the snapshot?

Ok so I've followed the steps as outlined in the documention below: Go to the VMs tab in the WebGUI. Click on the VM name to expand its details. Navigate to the Snapshots section. Use the available buttons for Revert, Block Commit, Block Pull, or Remove. Remove snapshot: This simply deletes the snapshot overlay file without affecting your VM. Your VM continues using the original disk file, and any changes made after the snapshot are lost. And now when I go to start my VM, it says the following error: I checked my vdiskpool/domains/Windows 11/ directory and the vdisk1.provisionedqcow2 file is now missing. Didn't you say that the snapshot creates a qcow2 file? Why did it remove the vdisk1.provisionedqcow2 file instead? There is a 'visk1.qcow2' file in the vdiskpool/domains/Windows 11/ directory but it doesn't seem to matter because it seems to be looking for a vdisk1.provisionedqcow2 file. Luckily I saved a backup of the file, and restoring it to the vdiskpool/domains/Windows 11/ directory works, but now I'm back to square one right? I can confirm that while running, the VM still has the reference to that vdisk1.qcow2 file located in /mnt/cache/domains/Windows 11/vdisk1.qcow2, but disappears as soon as I shut down the VM. How do I fix this? Please explain like I'm 5.

Just so I understand, is the qcow2 file the snapshot? Just trying to understand the logic of how removing the snapshot will fix this. Do you mean that the only thing left preventing me from relocating the qcow2 file into the new VM pool is that the snapshot is expecting it to be there? Does that mean that after deleting the snapshot I can just move over the qcow2 file into the new directory and it should work?

How do I do this, step by step? And do I risk losing anything by doing this?

Anyone?

I've tried this, although the weird thing is that when viewing the XML while the VM is running, it DOES make mention to the cache directory where the qcow2 file is located. However, I cannot make change to it while it's running. But when I shut down the VM, and again try to view the XML - the reference to the directory is gone! It simply doesn't exist anymore! Here is the XML when the VM is shut down: <?xml version='1.0' encoding='UTF-8'?> <domain type='kvm'> <name>Windows 11</name> <uuid>e05d58a1-e3fc-859a-7670-a211f88da6e1</uuid> <metadata> <vmtemplate

Hey guys, I'm trying to migrate my Windows 11 VM from my cache pool (mnt/cache/domains/Windows 11/) to a dedicated VM storage pool (mnt/vdiskpool/domains/Windows 11/). I transferred the 'domains' share to the 'vdiskpool' drive, ran mover, and then made sure there's no secondary drive for the domains share. The VM works fine until I realized that 'vdisk1.qcow2' was still located in mnt/cache/domains/Windows 11. So I tried to transfer the .qcow2 file from the cache drive to the vdiskpool drive. When I do, I get this message. It seems it's expecting for it to be on the cache drive. I've looked within the VM config (even the xml) and I cannot find any line which governs the location of this qcow2 file. At this point I remembered that I created a snapshot for this VM - not for any particular reason, just to see how it works. I don't really know how to delete it. I asked for help in the official discord server and a user called 'Kilrah' advised that I change the following highlighted lines in the snapshots.db file to /mnt/user/domains/Windows 11/. but after I did that and rebooted Unraid, I still get the same error. I can confirm that even after all this, copying the vdisk1.qcow2 file to /mnt/cache/domains/Windows 11/ still works flawlessly, meaning something else definitely still expects it to be there. Here is my VM config: Would deleting the snapshot somehow help? Should I revert the changes I made in the snapshot.db file? How can I fix this?

Thanks, that should be more than enough for 95% of the time. At the very least, Plex can fall back to the iGPU. I apologize and that's not my intention. If anything, I'm asking on advice in removing the patch. Now that I know the information above, I can do this confidently. I understand this, although since replacing a PSU is a major job (especially in the cramped case my system is in), I want to rule out software fixes first beforehand.

Just a follow-up on this to see what I need to do with this user script -- or if it's even necessary anymore to get unlimited transcodes.
