/dev/mapper/centos00-root FULL

[m3kvii]

Below is the output configured on a server acting as a gateway for veeam backups. The root directory is filling up with veeam error (a seperate issue I'm addressing with them). But i noticed the partition size is only 8 gigs even though the vm is 40 gigs. I am new to centos and not sure how to go about resizing it, I can back it up and take a crack at reallocating the partition to root directory. If I break it i can always revert to the back up. If someone can provide some insight into what I should read or research to re partition the drives, I would really appreciate it. Thank you in advance.

I just had this issue as well. Typically you would use lvresize to resize lvms but you have xfs in which you can't resize.
What I did on my server was moved my web files to /home and that freed up some space. But like I am still 88% full.
So in the future if you are using lvm don't use xfs so you can resize if needed.

You can resize xfs but you can only increase its size, not shrink.
