Is there a way to clone the LVM partitions faster? I think one possible solution is to clone the LVM partitions to regular partitions in another disk using dd, and then clone the new .

One method I found was to use the ‘snapshot’ feature of LVM to create a ‘frozen image’ copy of the logical volume, which is then suitable for copying to a new logical volume, while leaving the .
Create a new Ubuntu VM to use to perform this process. Attach the original drive + a new drive to be used for copying the data. Shrink the logical volume on the original drive. .Clonezilla is a partition and disk imaging/cloning program similar to True Image® or Norton Ghost®. It helps you to do system deployment, bare metal backup and recovery. Three types .
An easy way to do this is to plug the new drive into your computer, configure LVM and otherwise partition this drive the way you want, make the file systems, and then use rsync . The system setup is that we use LVM to manage the other phsyical drives, but importantly the root partition is not on LVM. . Under any other circumstances we would clone the drive using dd, but in this instance we would like to migrate just the LVM configuration from the old system disk to a new Ubuntu installation on a fresh disk.
cloning lvm partitions on hard drive
looks solid in terms of producing the exact clone on the second device; according to LVM and cloning HDs, is dangerous because LVM configurations are obviously duplicated in this case and, as a result, may result in data corruption if some renaming black magic is not done (I don't want to script that renaming unless we will not find another .
You're missing a step. After resizing the sdb3 partition and booting into the new system, you'll need to use the pvresize command to tell LVM that it is allowed to use the new space within the extended sdb3.. So: 2.5. Boot into the new system, then pvresize /dev/sdb3. In step 3, I would generally prefer using lvextend instead of lvresize - just as a failsafe: if I would . To make a clone of a system disk installed on an LVM system with the intention of booting from the clone we will perform the following steps: Prep the new disk (create partitions) create PV; Add the new PV to the same VG that contains the target LVs;Background LVM building blocks. Logical Volume Management utilizes the kernel's device-mapper feature to provide a system of partitions independent of underlying disk layout. With LVM you abstract your storage and have "virtual partitions", making extending/shrinking easier (subject to potential filesystem limitations).. Virtual partitions allow addition and removal without worry . "Need" is a strong word - there is more than one way to achieve what you want. With pvmove, you could do it on-line, while the encrypted LV is in use.. 1.) pvcreate NewDrive1 2.) vgextend VG1 NewDrive1 3.) pvmove OldDrive2 (means effectively: "move any LVM-allocated extents from OldDrive2 to any other drive(s) in VG1 so that OldDrive2 becomes completely .

I'd like to know how it's possible using the lvm cli tool to clone an existing lvm thin volume, creating another thin-volume with the same contents (but possibly a larger size) as the original one. So something like LXC does when you execute lxc-clone. Use LVM Mirror copy. This will copy the data live to the new location (including any updates), for as long as the mirror runs. See 4.4.1.3.Creating Mirrored Volumes at CentOS. Once you have the data cloned, you can "break the mirror", and specify that you want LVM to look at the "new" drive vs. the "old" drive when that happens.
Or is there a better approach to clone the disk as this seems to be a LVM-volume? This assumes that once shrinked with - say - 150 Mbytes, CloneZilla is able to do its magic. Thank you for any feedback and/or suggestions. With warm regards - Will ==== Output of . I inherited a machine that's set up with 3 disks, managed by LVM (v 2.02.46-RHEL5). I just got a new box with the same hardware configuration, and would like to clone the disk setup by copying an LVM config file from the first box to the second, and have LVM on the new box set up the disks according to that same configuration.
Then I checked the lvm archive, which keeps a record of all changes: sudo ls -l /etc/lvm/archive I made a note of the most recent archive file for the ubuntu-vg11 group, and edited it, altering the UUIDs of the LVs listed in the file.
At installation, I created an unencrypted LVM with 3 volumes, including a 30 GB volume I installed the system on. I want to backup the system, so I picked Clonezilla to backup the 30 GB partition. Unfortunately, Clonezilla only offers me to clone /dev/sda, that is the whole 1.4 TB partition. As if it didn't recognize the LVM. Set up partitions, raid, lvm and filesystems as it is on the source disk. You'll need to either clone the various uuid's too, or take note of the changes to update the relevant configuration files (bootloader, fstab, etc.) later.As of the LVM in Debian stretch (9.0), namely 2.02.168-2, it's possible to do a copy of a logical volume across volume groups using a combination of vgmerge, lvconvert, and vgsplit. Since a move is a combination of a copy and a delete, this will also work for a move. Alternatively, you can use pvmove to move the physical extents instead. The above is true for Linux LVM version 2, which has existed since the beginning of the 2.6 kernel series. If you deal with 2.4.xx or older kernels, you might have LVM version 1, for which the vgexport/vgimport commands might have worked differently (I don't remember the details of those any more).
GOAL: Clone a volume group in LVM. Cause. CAUSE: An LVM volume group needs to be cloned for testing purposes. Answer/Solution.

I want co copy not to move data. My operating system is Debian. On LVM partition I have running Xen virtual systems. Information about my disk with LVM (/dev/sdb):
The answer by trekkerboy / modonnell @ linuxquestions is most straightforward, use vgimportclone.. Note also that after you create the clone, you have to activate it with vgchange -a y newvgname, and you have to clean up oldvgname's device nodes with dmsetup remove /dev/oldvgname/*.. For reference, what follows is a more manual method, which . Clone LVM based installation to larger drive and extend root partition to use new space. Ask Question Asked 7 years, 5 months ago.

I wonder if the problem you are having is that Testdisk is looking for useable partitions and not recognizing it as an LVM partition. One thing which might be worth looking at (although not sure if it will help epubs, although it should be able to recover PDFs) is "Photorec" - which will scan the raw disk and try and recognise content based on signatures and recover it.
I googled many times but couldn't find an answer. What I want is cloning an LVM thin provisioning volume to another thin volume. For now I know dd can clone a thin volume as following:. dd if=/dev/mapper/vg_thin01 of=/dev/mapper/vg_thin02 bs=1MTrying to clone with clonezilla is of course resulting in errors as the NVME drive I would be trying to clone to is smaller than the source disk. Goal/Objective: I am only utilizing approximately 50% of my lvm-thin. Is it possible to shrink it by about 20GB? At that point I would imagine I could clone the drive. Another option. I have my VMs .Cloning a disk with LVM dd the right way to clone the entire disk? Uhm, no, dd generally isn't the right way. Not impossible, but generally not best way. If you're going to do it with dd, you need to do it when all LVs are not active, or are at least all set to read-only. With that you should be able to get something at least recoverable.
This type of cloning is convenient to change partitioning or file systems – for example, to clone from a complex partitioning based on LVM to a simpler one without LVM, or from a LUCKS-encrypted partition to an unencrypted one, or vice versa. Furthermore, file-level cloning allows synchronizing of the clone with the original disk.前の記事lvm 概要構成概要複数の物理ボリュームがあり、その上に複数のボリュームグループを作成することができ、その上に複数の論理ボリュームを作成することができます。複数の物理ボリュームを使用.
