This article is to share with you about how to expand the root directory space in CentOS7, the editor thinks it is very practical, so I share it with you to learn. I hope you can get something after reading this article.

1. Create two physical volumes:

Pvcreate / dev/sda1pvcreate / dev/sdb1

(note: if these mount points already exist, you will be prompted whether to overwrite or not. Type y directly to determine the overlay.)

two。 Extend the centos volume group:

Vgextend centos / dev/sd {a,b} 1

3. Extend logical volumes:

Lvextend-L+XXXG centos

(note: XXX is the size that needs to be expanded, in G)

4. Apply extended logical volumes to the root partition
