I have not provided examples of LVM arguments that will be different for you: VG, LV, PV, block devices. Read the documentation for usage details. # Old host in rescue mode .When you create a logical volume (LV) within a VG, LVM allocates physical extents on the PVs. The logical extents within the LV correspond one-to-one with physical extents in the VG. . Moving a volume group to another system. . This leads me to the topic if this post, how to migrate a logical volume from one volume group to another. Let’s dive in: NOTE: This example shows how to migrate the “optopenv” LV from “rootvg’ to “nbuvg” and renames the LV to “nbu_optopenv_lv” Create new VG (or use an existing VG)
pvcreate erase all data on disk (and prepare for LVM) lvcreate sould create a logical volume lvol1, you specify lv name with -n bar; I use HP-UX syntax for lv, you might have to use /dev/mapper/myvg-mylv syntax; Once you have verified data are OK, in new place: you can safely delete old /bar; edit /etc/fstab to use new /bar short answer: you can't long answer: data to be freed is inside another disk on another vg. you would theorically have to: shrink filesystem / this is done by umounting / (booting on a live disk, use fsck, resize2fs) this is the hardest part.; shrink logical volume ( lvredure --size -400G lv_root), you now have 400 Gb free on vg01 (more likely free space is between lv_root .First I would take a snapshot of the lv: lvcreate --snapshot --name my_shot --size /dev// After that you have to create a new lv on the new host (e.g. using lvcreate) with the same size. Then you can directly copy the data to the new host. Here is my example of the copy command:Environment. Red Hat Enterprise Linux; LVM; Issue. How do I move a Volume Group from one system to another? Resolution. To move a whole volume group from one system to a new system, the vgexport and vgimport commands can be used.. Note: These steps are only for the local disk, not for the Directl Lun mapped to the system.
For the reuse disks option, it is prudent to deactivate and export the VG, so the old system will not attempt to use it. Examples you might see of this are under the use case of moving a VG to another system. I have not provided examples of LVM arguments that will be different for you: VG, LV, PV, block devices.
Note that in the original question, the root LV might be just slightly bigger than the new md10 PV. As a result, using pvmove with pvmove -n lv.root /dev/md01 /dev/md10 /dev/md20 would allow any parts of the LV that won't fit into md10 to overflow into md20 in a controlled manner. After lv.root is done, you could then use pvmove -n lv.cache /dev/md01 /dev/md20 to explicitly .
Since you can only move an entire PV from one VG to another, it is not going to be possible to move all free space from one VG to the other. But you can get there part of the way: First, move all data on one of your PVs to some other PV: pvmove -v /dev/sdb1 This will start moving the data to the other PVs, away from sdb1.Copying a raw logical volume to another physical volume To copy a raw logical volume to another physical volume, perform the following steps. Creating a file system log on a dedicated disk for a user-defined volume group A JFS or JFS2 file system log is a formatted list of file system transaction records.

Every LV in the VG is searched for contiguous data that need moving according to the command line arguments. For each piece of data found, a new segment is added to the end of the pvmove LV. This segment takes the form of a temporary mirror to copy the data from the original location to a newly allocated location.
3 - Add the new PV to the same VG as the target LV. You can list the logical volumes with vgs (I will use "mint-vg") and add the new PV like this: . ubuntu 18 lvm move to another disk (also lvm) - backup and restore. 1.

Visit Stack Exchange This may not be an option in all environments. If other volume groups contain the required free space, the alternative is to move the required logical volumes to the desired volume group and expand them as needed. The source logical volume can be moved to another volume group with the cplv command. The following steps achieve this.
[root@testsyst ~]# lvdisplay --- Logical volume --- LV Path /dev/vg_testsyst/lv_root LV Name lv_root VG Name vg_testsyst LV UUID VzQzcz-NssK-8BIT-qtjz-XJho-0Mwd-fEbph1 LV Write Access read/write LV Creation host, time testsyst, 2014-05-01 23:51:39 +0530 LV Status available # open 1 LV Size 50.00 GiB Current LE 12800 Segments 1 Allocation .Alternatively, move the hibernation/swap space to your 70GB free space, delete the lv_swap volume and add some space to lv_root. To answer your second question: no, you don't need to move LV volumes. That's the beauty of Logical Volume Management; you can shrink or expand volumes without having to move then, in contrast to fixed partitions.If I have (2) thin pools (vg/pool1) and (vg/pool2) inside the same volume group, with an LV inside the first pool, is there a LVM command to move that LV to the second pool? Would pvmove do that?
I got 'No extents available for allocation'.then I add third disk 10GB create pv add to vg1 then run pvmove /dev/sdb /dev/sdd system restart and hangs I poweroff it when start I edit start options add init=/bin/bash then I type /usr/sbin/lvm and run pvmove /dev/sdb /dev/sdd got success but next run /pvmove /dev/sdc /dev/sdd failed
This is not possible, because PVs are either part of one VG or another. To "move" the LV between would therefore mean to physically put it from one PV to another and this means: recreate it and copy the content. bakunin. bakunin: . LVM - Extending Logical Volume within Volume Group.
[SOLVED] Move LV to a different PV (same VG) Hi guys, I need some assistance moving a LV. I have a VG with two PV; on the second PV there is only one LV so I want to move it to the first PV (hdisk1) in order to get rid of the second one (hdisk2) . WARNING: be careful when operating on LVM, errors may destroy data with almost no chanche of .
So you can't actually take a fragment of a PV (ex. 100GB from /dev/sdd1) and dedicate it to another another VG (ex. VGP4-CHK). In other words, VGs own their PEs entirely. Fundamentally, to increase the storage of an LV (ex. VGP4--CHK-LVP4--CHK) you need to: Allocate the space necessary in the LV's VG. Extend the LV to encompass the additional . # check where there is free space pvs # check in detail if free space is contiguous pvdisplay --maps /dev/sda # show LV segments that require moving, in order lvs -o seg_le_ranges VG/LV At this point you should have a clear idea what to move where.
