In case vgmerge doesn't fit your needs, you're to create another volume of equal or bigger size in the destination VG and then simply dd from source to destination .

In other words, copy the data directly from .Normally you would now run pvmove /dev/md01 and vgreduce vg.system /dev/md01 to move all data away from /dev/md01 but want control over which lvm data goes where, .

This article will guide you on how to move or migrate LVM and volume group from one server to another. Let’s move a volume group named ‘server1_data_vg‘ from one system to another, which is . First: you should give /dev/sdaX to the volume group tiffany-vg: vgextend tiffany-vg /dev/sdaX. Second: you should move all of your data between the (already) .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: 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 .

It is quite easy to move a whole volume group to another system if, for example, a user department acquires a new server. To do this we use the vgexport and vgimport commands.

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. I need to move the group "tiffany-vg" to the new/larger disk (/dev/sda), with the aim of removing the older 250GB physical disk from the server. The target disk already contains another LVM group called "xen-vg" which must remain separate. I want to move "tiffany-vg" to sit next to "xen-vg" on /dev/sda and I really need to not lose any data!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 .

How to migrate (move) logical volumes and volume groupsIf 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?

Boot Fail - Extend LVM ("root", "/") over RAID 1 (CentOS 7) 0.

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. 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.
