Unused disk, want to remove it...

[csl]

Hi,

It's a bit of a long story, but I had a TPM disk that was under local-lvm (a Windows 2022 machine) that I wanted to move to my own 'storage' elsewhere. It wouldn't let me.

So I tried to delete it and then get a new TPM that is live an kicking. Hooray!

But the first disk, that used to be a TPM disk, is still here. It won't disappear, no matter what I try (disk running, disk turned off etc.).







What should I try next?

Thanks,

Alex

It's going to be "delete the snapshot", isn't it?

noooo!

Ok, I deleted the snapshot, wiped the old TPM, got a new TPM... and now it tells me: 'The current guest configuration does not support taking new snapshots'.

Really?

I now know I have ruined doing TPM in the same area as rest of the disk space.

"The current guest configuration does not support taking new snapshots"

I know doing Windows is a chore, but really?

I remember seeing that before on this forum. The raw format of the TPM file storage does not support snapshots. I don't remember the work-around (as I don't use it), sorry but it might be somewhere on this forum.

I worked backwards and put the TPM's back on local-lvm and then snapshot's were available again. It wasn't any bother because I had nothing encrypted. I don't understand why TPMs aren't qcow2 or why they can't create a snapshot, but as long has you don't have things encrypted (read this online?) you are ok to drop one and start another elsewhere.
