    Snapshot Überbleibsel?

    Hallo Proxmox-Community, wenn ich mir den Inhalt meines thinpools anzeigen lasse finde ich bei mehreren VMs Disks, die sich sehr wie Snapshots anhören, Beispiel: vm1XX-state-vor-ispconfig. Diese möchte ich gerne löschen. Gehe ich aber nun auf die Anzeige der VM und dann auf Snapshots werden...

    Storing ISOs in thin LVM

    HI, I created a thin lvm storage and added it to one of my nodes. It all worked fine and it can store vmdisks. But i cannot upload any to it since it is a block storage, not a file storage. What is the best way to enable storing ISO images on it? Mounting it and creating a filesystem?

    Managing the size of a FDE VM

    So I made a full VM and installed Debian 9.3 using full-disk encryption. Now, Proxmox uses LVM-Thin to store VM drives, which is smart, because LVM-Thin only allocates data when it is actually written. However, when using FDE, Proxmox can't tell what is written and what is not (at installation...
