  3. 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...
  4. 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.

  8. 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...
  9. 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...
