I am a graduate student of computational chemistry with access to a Linux cluster. The cluster consists of a very large (25 TB) fileserver, to which several dozen compute nodes are connected. Each compute node consists of 8 to 24 Intel Xeon cores. Each compute node also contains a local disk of about 365 TB.
I want to see how many files are in subdirectories to find out where all the inode usage is on the system. Kind of like I would do this for space usage

I’m currently using iostat -d -p, but that is limited to the whole partition.
For example, this is the first line of my /etc/fstab:
