Replace Proxmox host hardrive with minimal downtime (LVM)

[Inglebard]

Hi,

I need to replace the hardrive of my proxmox host. I test the following which seems to work but I would like to know if there is a better way or if problem can occurs in the future.

Here is the step I have done with a running test proxmox.
The setup :
Current disk : /dev/vda with (vda1 : bios boot, vda2 : Efi, vda3: lvm )
New disk /dev/vdb

sgdisk --backup=table.gpt /dev/vda
sgdisk --load-backup=table.gpt /dev/vdb
dd if=/dev/vda1 of=/dev/vdb1 bs=4M conv=notrunc status=progress
dd if=/dev/vda2 of=/dev/vdb2 bs=4M conv=notrunc status=progress
pvcreate /dev/vdb3
vgextend pve /dev/vdb3
pvmove /dev/vda3 /dev/vdb3
vgreduce pve /dev/vda3
shutdown -h now

Then remove the old disk and reboot.

Is it a proper way to do this ?

I replaced the Proxmox system disk with a larger, faster one a while back.

I documented it on my blog (it's in Spanish, but the Google translation into English is pretty good):

I know that when I posted the information on this forum, many people replied saying it was helpful ;-)

I hope it helps you too.
