Merging disks? Convert root partition to lvm?

I have a $5/Month Droplet, which has a 20 GB disk. Then I add a 10 GB block storage to it. Now my Droplet has 30 GB space. But these 30 GB are not continuous, when disk1 is full, system will not write data to disk2, instead, system throw a “No space left on device” error.

So I tried to merging disks. LVM seems to be a good choice, so I tried to convert root partition to lvm. I found some instruction on Google, but I just can’t make it work, I just keep crash the system since I am a noob.

Is there a detailed Instruction for convert root partition to lvm on Droplet? Thanks!

I’m having the same issue as well. I wish to merge my root partition to my newly added volume block. When I run out of space on my first volume /dev/vda1 wont go over to /dev/sda1.

Hi Uter,

Thanks, khalid
