thin provisioning

I have two containers A and B. Container A #101 has only a rootfs: arch: amd64 cores: 1 hostname: A memory: 2048 nameserver: 127.0.0.1 net0: name=eth0,bridge=vmbr0,firewall=1,gw=x.x.x.1,hwaddr=xx:xx:xx:xx:xx:xx,ip=x.x.x.7/24,type=veth onboot: 1 ostype: alpine rootfs...

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...

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. Everything works flawless. The problem it's when I go into PVE GUI -> PBS storage -> Backups -> SomeVMwithBigVirtualDrive ->...

Hi, I have succesfully configured a Proxmox cluster with only 2 nodes at the moment (planning to add 2 more nodes) and I'm experimenting different storage configurations. I'm using an old setup no longer supported from Dell: - 2 x Dell R720 - 1 x Dell MD3800 - SAN The SAN is connected with...

Hallo zusammen, ich bin relativ neu im Proxmox / Linux Umfeld und bitte deshalb um Nachsicht. Ich habe vermutlich ein Problem mit einer überprovisionierten VM, bzw. einem ZFS Pool und bräuchte hier dringend Hilfe. Festgestellt habe ich es beim Restore eines Backups der VM. Hier erhalte ich beim...

Hallo Forum-User, ich besitze ein Intel NUC mit einer Crucial BX500 (120GB SSD). Auf dem Host ist bereits fstrim.timer aktiviert. Jetzt habe ich in der Anleitung gelesen, dass ich dies ebenfalls in den VM's aktivieren muss, dazu muss das Laufwerk aber "Thin Provisioning" untersützten. Dazu muss...

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...

Hello, i have seen that if i add a new storage, this is definide by something like zfspool: mystorage pool mystorage content images,rootdir sparse 1 in /etc/pve/storage.cfg My question is, using ZFS, where is defined Thin provisioning? Thanks!

Hi, I have set up a thin pool for container creation. When I create Cts the filesystem is formated with ext4 automatically. is it possible to create containers with XFS instead of EXT4 using thin provisioning? Regards

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...

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...

Hi, I have a Proxmox server with a bunch of local disks (10 + SSD for ZIL and L2ARC) mounted in ZFS Raidz2 for the VMs. When I have mounted the storage I forgot to enable the Thin Provision. I have many VMs running on this storage and I want to know if it's possible to enable now without...

Hello I've been having a problem with a thin-provisioned filesystem on ZFS. Right now I'm not really sure if its a problem with proxmox or the guest. Right now my setup is: ZFS: NAME USED AVAIL REFER MOUNTPOINT rpool 10.2T 47.1G 140K /rpool...

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?

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...

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...

hi, why do qcow2 and vmdk not use thin provisioning? regards
