As the amount of data we store continues to grow and grow, there is bound to become a time that you will need to resize your partitions to add more disk space. On our of my MySQL replication virtual servers, I created it initially with a 200GB disk. After moving all the data over, was wishing I would have had a bit more space. Good news is this can easily be done. I should note that I am using raw image files, not lvms, so there is a bit more work required.
I’m starting to work on replacing my CentOS 6 KVM server with a new CentOS 7 server. As much as I dislike CentOS 7, I’m trying to give it an honest try and make an honest attempt at learning. Working in the IT profession requires you to constantly adapt to change and learn new tech stacks. The problem I have is in CentOS 6 it was so easy to install KVM and set up a VM. CentOS 7 has been issue after issue. The most recent being the “Could Not Access KVM Kernel Module: Permission Denied” error.
