My ubuntu--vg-ubuntu--lv out of disk space

  • 772

I am out of disk space and have been trying for 2 day researching to expand my vda3 ubuntu--vg-ubuntu--lv into the vda 250GB slot using lvextend but it has not worked for me. Could someone help me out here? Thanks (unbuntu 18.04.)

I did a df -h and the 250 GB disk does not show:

FYI, I also added the extra 250GB of disk space via the virtual station settings. However, because the 250GB did not show in my df -h I sarted attempting the use of lvextend cmd. Which I found here.

I am installing ubuntu server 18.04.5 and for speed sake, without GUI installed. So cannot use GParted.

  1. Your 250GB disk only has about 50GB of partitions. You probably have about 200GB unallocated. This should be obvious if you open GParted. Assuming this is the case proceed as follows:

    Make sure you backup any data you cannot afford to lose.

    Follow this guide from the section below Logical Volume Extending https://www.tecmint.com/extend-and-reduce-lvms-in-linux/

    Don’t forget to complete the resize2fs step.

    If you need more help ask specific questions

    Good luck
