LVM can expand a partition while it is mounted, if the filesystem used on it also supports that ( like the usual ext3/4 ). When expanding a partition, gparted can only expand it into adjacent free space, but LVM can use free space anywhere in the Volume Group, even on another disk. Using typical paritions often means that you must move other partitions around to make space to expand one, which. $ mkdir -p /home/user/usb $ sudo mount /dev/sdc1 /home/user/usb $ cd /home/user/usb $ ls -l total 200 -rw----- 1 schkn schkn 32768 Apr 20 2019 file1 drwxrwxr-x 6 schkn schkn 4096 May 9 07:01 directory1 lrwxrwxrwx 1 schkn schkn 7 Aug 14 16:38 link1 drwxrwxr-x 2 schkn schkn 4096 Jan 5 2019 directory2 .

Unmount if necessary. Use fdisk -l to check the order of drives. In my case, sda is the old system disk, sdb is the USB stick, sdc is the second hard drive. Use dd to copy the entire system disk to the second drive, with pv monitoring progress. Don't overwrite your system Grml is a bootable live system (Live-CD) based on Debian. It is not necessary to install anything to a harddisk. Grml includes a collection of GNU/Linux software especially for system administrators. It specializes on administrative tasks like installation, deployment and system rescue. What are grml32 / grml64 and grml96? grml32-full: 32bit version (kernel and userspace) grml64-full: 64bit. U buntu Live CD or a USB drive comes in handy at times when something goes wrong. You can do things like recovering data, check for hard disk errors, or even restore the Grub bootloader. It's easier to mess up the Grub when you have changed the configuration of your computer

How to mount LVM partition on Ubuntu - Quonn's Blo

  1. Ich habe die offizielle Anleitung verwendet und mich für LVM entschieden, da wir die virtuellen Plattengrößen später noch mehrfach anpassen werden. Die Partition sieht so aus: Model: Virtio Block Device (virtblk) Disk /dev/vda: 8590MB Sector size (logical/physical): 512B/512B Partition Table: gpt Disk Flags: Number Start End Size File system Name Flags 1 1049kB 3146kB 2097kB BIOS boot.
  2. Ah, noticed I have LVM. Getting close since I could now mount lv_swap and lv_root using listings 7 and 8 at: Like using a FAT32 partition attached to another VM then boot into another live CD in the VM and manipulate it and output to the FAT32 partition. Exit the VM and use Folder2ISO to make your ISO image (obviously removing or adding what ever you want before hand ie. Kernel etc) and/or.
  3. In this tutorial, we will learn how to mount (attach) a drive in Linux with the EXT Linux file system, FAT or NTFS using mount command. We can use the same command to mount the USB drive and ISO image as well. On both Linux and UNIX like operating systems we can use mount/umount command to attach/detach devices
  4. Within the live cd I could see the /dev/sd* devices and their partitions which were described as lvm by using the parted application. Type. 1. parted. and then. 1. print . to show the partitions. Before you try to reinstall grub, the root partition needs to be mounted. Without LVM then it would be simple: 1. 2. mkdir-p / mnt / root. mount / dev / sdaX / mnt / root. However with lvm the system.
  5. Als Newbie habe ich bei der Installation von Proxmox allerdings alles erstmal in das große local-lvm Volume geworfen und kann die virtual disks der VMs nun nicht mehr einfach so mit Veeam abgreifen und sichern. Mein Ansatz war jetzt folgender: Alle VMs und Container aus dem local-lvm raus, dieses löschen, den Speicher local erweitern (da nur 100GB groß) und die VMs und Container dortin.
  6. I have use the 2.0.1-15 clonezilla live cd to create on a usb drive a disk image of my DL380 g5 server (rhel 5, with a raid 1 disc, a /boot on its own partition and the remaining space is used for lvm). The creation was successful but I can't restore the image. When I restore the image, it can restore the /boot partition but it fail after that (seem that the lv are created but then the tries.
