    Thin Provision after the fact

    Hi, I've searched the forums but I couldn't find an answer to my specific question. I have a zfs mirror setup without ticking thin provision, and added a pile of VM disks in there. I've copied all my data to these disks. I've now realised that I would have liked to tick Thin Provision on...

    [SOLVED] How to restore VM using thin ZVOLs

    I have a PVE node with some CT & VM on ZFS. The second ones with thin provisioning on ZVOLs. Now I have installed PBS in another computer to learn how to backup my CT/VM.

    Cloning PVE 6.1-2 From One Disk to Another

    New to Linux so forgive my ignorance about anything. Hoping to switch off of HyperV. I setup a single 120GB SSD non-UEFI computer with the storage defaults (Not ZFS). I customized a great many things and then used a HDD duplicator to clone to a 250GB destination disk. To my surprise the cloned...

    Unterstanding how snapshots under LVM Thin-Volumes work

    Hello, I work with Proxmox 5.2 and LVM Thin-Volumes. I create a couple of snapshots from a windows test-vm and wondering how it worked. A normal thin snapshot under LVM2 used the same size as the original thin-volume has. In my case the thin-lv has 32GiB, so the snapshot would become also...

    Convert Directory storage to lvm-thin?

    I have a PVE host which was originally installed on PVE v3 with Directory type storage for local disk images. It is now running 5.3-5. I would like to have the disk images stored on lvm-thin so that I can trim them (the disks are .raw images). Is there a way of doing this that doesn't involve...

    Storage live migration and thin provisioning

    Hi, the storage live migration creates a thick provisioned target even if a format like qcow2 is selected. I only found the announcement for PVE 3.0 where someone mentioned to use qemu-img convert afterwards to create a sparse image file. But how would this be done on a running VM?

    Thin Provisioning (Sparse) Volume

    Greetings. Out of the box on Proxmox 5.x installs, the RPOOL volume is enabled with thin provisioning. Specific application: I use NFS volumes as export shares from the RPOOL. So, for example I share out /var/lib/vz which is part of the rpool. My nodes can then create VMS in that storage...

    Trim virtual drives

    Hey everyone ! We were moving disks from a storage to another and noticed that when they arrive on the new storage, the thin provisioning expanded to full space. Before, when we had a few VMs, we could use the old method to empty the disks (using dd to fill the disk with zeros and deleting...
