Extending a CentOS Linux LVM partition by increasing an existing virtual disk size

In this video you will learn how to extend a Linux LVM partition. I will demonstrate how I can extend my /var partition by extending an existing disk. You can follow similar steps for virtual box, vmware workstation and vmware player VMs.

Enjoy!

I did it on Ubuntu server in VirtualBox and it worked. Million thanks.
I spent about 4 hours searching the Internet. Your video is the first working solution.

[k.s]

I forgot to write G after L+. Then it updated by 4.99 MB.


Great video. Thanks

this worked, for me on vmware workstation 10, thanks!

Thanks a million, it work in centOS 7.

Thanks a bunch!  How did you figure all this out?

The vg name seems to be "centos" for CentOS 7.
Use "lvextend -l +100%FREE /dev/centos/root" to get the exact free space left.
CentOS 7 also switched to xfs so replace resize2fs with "xfs_growfs -d /".

Great! One change is there in centos 8. We will have to use xfs_growfs mount point

Thank you very much It helps me. But hte last part "lvextend" not working in centos 7 and I use "xfs_growfs".

Excellent video and this is exact which I was looking to extend my volume. One more favor expecting i.e. last step resize2fs didn't work and ultimately my problem as it is.. Brother if you can help in this regards would be best favor. My OS is Cent OS 8

Hi, thanks for the video. I have a iscsi SAN the native capacity is 30TB and I assigned 20TB to a Centos 7 box as sdb but now I need extend from 20TB to 30TB to the same sdb, if the steps shown in video work for me too?

what if I have sd1 to sd5, and cannot add new?

[DerfAU]

Thanks Helped heaps on Cpanel when my root volume was full and nothing except .html files would load. (e.g. sql, mail, etc) ran out of memory

Please correct these issues and rerun updates.
fatal: cPanel & WHM cannot update due to insufficient disk space. The system detected 0.00 MB free, but requires at least 1 GB free at '/usr/local/cpanel' in order to successfully update.
fatal: Your RPM database appears unstable. It is not possible at the moment to install a simple RPM.

You saved me from getting fired! hahaha!

You need to do the same DEMO with using only FDISK assuming you don't have LVM tools.

[honestreview]

was that the root partition that you extended. i need to extend the root partition of my VM. not sure how to do this.
