Thank you for the reply, but unfortunately it still shows the original size 32GB. LnxBil Famous Member. Feb 21, 4, Germany. If it is a zfs volume, it cannot be changed directly.
Recreate the volume manually and dd the data to the new volume. Thanks for the reply LnxBil, but I don't have enough space for the data duplication in the real situation a need to shrink 1 TB disk. ZFS does not save "free" space. Have you enabled thin provisioning? If not, you can get space by setting refreservation to zero. You can also write zeros to the device and ZFS will free the blocks immediately if they are not referenced by a snapshot.The article index for this TB 10Gbit server series can be found by clicking here.
It should contain everything you need to accomplish the same as in the video! This is going to be a bit more basic level tutorial video but I have some more in depth stuff planned for upcoming videos! Then we are going to look at some BIOS settings and after that run through the installation process together. Right, so to get started we need to download the newest version of proxmox.Bob cnc 3
On the download page download the ISO file, we are going to use the 6. Once both are downloaded and etcher is installed, insert your USB stick Anything 1GB or more should be fine and start etcher. Ok, stick done! This enables certain virtualization features inside of your CPU which Proxmox wants to use.
This disables the loading of option ROMs during boot. Ok, hit F10 to save all changes and hit F12 to get into the boot override menu. Once booted you should be greeted with the following screen. There hit the first option to Install Proxmox. Then we get to the storage configuration for where you want to install Proxmox. Here we are going to make a few changes! As you can see all the disks Proxmox detects are now shown and we want to select the SSDs of which we want to create a mirror and install Proxmox onto.
Then we want to do a little tweaking in the advanced options.Exponential growth and decay word problems multiple choice
Only change compression from on to LZ4. Then we also want to change the hdsize value. Set a password and enter an e-mail address.To increase the disc size from the command line, login to the Proxmox host.
Proxmox provides great tools for this right out of the box. The following Command will create a compressed archive of the VM with all its configuration and data. The following command will show more details about the VM, including the disc type and size. To check the Disc image details you can execute the following command.
Resizing a disc image has a couple of limitations. One of those is that it is not possible to decrease the disc size. Another limitation is the snapshot feature. A disc image with a snapshot is not resizeable. The output above shows an example of an image with snapshot.
Proxmox VE – Resize your virtual Hard disks – Part I
You will notice a error message like this in the console. At the time of writing, the Proxmox web interface is sadly not reporting this situation back to the user with all the details.Newifi d2 firmware
The Proxmox web interface will simply show a message like this giving no clue about the actual reason. The disc image connected to virtio0 is now increased in size by 14 GB.
As qcow2 disc images are only as big as the data stored inside the disc image, the filesize will be not effected by the resize operation.
Increasing the disc image allows the disc now to grow to the new size of 20GB instead of the old size of 6GB.
ZFS: Tips and Tricks
To change the size of the partitions inside the qcow2 disc image, the disc needs to be availabe to access it exclusively. If the resized disc is not the boot disc, you might be able to unmount the disc from the running VM and follow the instructions to resize the partitions.
If the resized disc is the boot disc of the VM, it is common to use a Live OS boot medium containing all required tools to boot the VM in a state where the disc is not used. With access to the Proxmox host and its commandline, this step is not needed. The disc image can be made available to the Proxmox host to perform the required steps.
That is possible via qemu-nbd nbd stands for Network Block Device and allows to connect the qcow2 disc image representing a virtual block device as a device to the system. The required kernel modules to do this are already installed with the Proxmox environment but not loaded into the kernel. Thanks to the flexibility of the linux kernel, such modules can be loaded at runtime.
This will load the qemu-nbd kernel module. With it loaded qemu can connect the disc image of the VM to the system.A quiz has multiple choice questions each with 5 choices
Before connecting the disc image to the system, make sure the VM is stopped. There will be no output from this command on success. The result of it will be a device connected to the disc image resized earlier. The above package need to be installed on the Proxmox host to allow the different tools to interact with the connected disc image properly. To resize the disc, the partitioning tool parted is used to change the size of the root partition on the disc.
The following output shows the partition table where the free space is shown. The partition with the number 2 is an LVM containing the logical volume of the root filesystem. This is the partition that will be resized.
After this step, the disc is increased and the partition size is changed as well. This is it for the tasks to be performed on the Proxmox host itself.Forums New posts Search forums. What's new New posts Latest activity. Members Current visitors New profile posts Search profile posts.
Last edited: Feb 3, When you resize the disk of a VM, to avoid confusion and disasters think the process like adding or removing a disk platter. If you enlarge the hard disk, once you have added the disk plate, your partition table and file system knows nothing about the new size, so you have to act inside the VM to fix it.
If you reduce shrink the hard disk, of course removing the last disk plate will probably destroy your file system and remove the data in it! So in this case it is paramount to act in the VM in advancereducing the file system and the partition size.
Another page deleted with overlapping content was Resizing disks Archive. Use gparted or similar tool recommended In gparted and possibly most other tools, LVM and Windows dynamic disc is not supported. Boot the virtual machine with gparted or similar tool, enlarge the partion and optionally the file system. With som linux clients you often need to enlarge the extended partion, move the swappartion, shrink the extended partion and enlarge the root partion.
Gparted have some warnings about some specific operations not well supported with windows guest - outside the scope of this document but read the warnings in gparted. Note that the partition you want to enlarge should be at the end of the disk.

Last edited: Nov 15, May 2, 3, I'll dig to see how to resize metadata pool i thought it was done automatically.Proxmox VE ZFS Part 5 Adding More Disks to ZFS Pool
Resize2fs tells me the size il already correct. If I read that correctly - you have increased the thinpool size lvdockerbut not the LVSize of vmdisk-0 - use lvresize or the GUI for that after resizing the metadata. After the LV vmdisk-0 is resized - you need to do the steps in the guest.
If we try the above df -h we can see that nothing has changed, this is because the partitions are the same, lets change that…. So lets edit the partition map here is the part that I find scary since we are going to delete the partition…. Now in order for the system to notice the change there are probably several ways to do this, but the easiest is to reboot.
Great post, I managed it with help of gparted live ISO, and then I followed last part from this tutorial. I wonder why Proxmox does not find another solution for this. By the way, wonderful job here, I find useful especially the articles regarding proxmox templates. I use it too for provisioning, keep on learning. Like Like. You are commenting using your WordPress.

I am going to be using fdisk to resize the disk instead of gparted or similar. Changes will remain in memory only, until you decide to write them.
