Centos 7 file system question


#1

Hi all,

I have a Centos 7 server that I inherited (I’m not a centos guy) . And the /dev/mapper/cl-root is almost full.
I’m I right in saying that /dev/mapper/cl-root is the root partition, ie where /bin /etc and /var live?

Just need a sanity check :laughing:

Try a df -h, that should clarify things for you. This is what my CentOS 7 looks like. So my root partition is
/dev/mapper/centos-root

$ df -h
Filesystem               Size  Used Avail Use% Mounted on
/dev/mapper/centos-root   14G  5.6G  7.8G  42% /

This may answer your question no reason to re-invent the wheel https://unix.stackexchange.com/questions/204413/dev-mapper-in-fdisk

Sorry apparently forums are hard…
