Merging disks? Convert root partition to lvm?

Posted on March 25, 2017

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!

Hi Uter,

I want to inform you that converting root partition is require a lot of effort and very complicated.What i can suggest you to move some of the bigger directory to some other new LVM partion like /var /home/ /opt. like which are the folder utilizing the most of the space and then move it to new partition.you can determine the space using below command. du -sh /var

Please format the partition as LVM and visit below post to mount any directory to new partition which utilizing most space.

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.
