How to find out mount/partition a directory or file is on? (Linux Server) [closed]

Question

Is there a Linux command to easily find out which partition/mount a directory or file is on?

(This is probably a RTM question, and I feel guilty for asking it, but somehow, I can't find a good answer on google just yet..)

@ErdemEce that's my point. ina mentioned RTFM, but Google (and what it links to) counts as a manual now :-) – Swivel

getting the mount for a directory to troubleshoot a low diskspace error in order to restart a jenkins node that runs the CI loop for your team's web stack seems awfully like a tool used primarily in programming... – Hypermetropia

@Hypermetropia Agree. I have exactly the same issue and got my solution here as the accepted answer below. – Pyrrho

The various program ways to achieve this are described well at unix.stackexchange.com/a/313502/103306 – Nymphomania

I get following when I run above command. /dev/mapper/vg_mymachine-lv. how do I know on which primary partition it belongs too. i.e. sda1, sda2, hda1 etc? – Peekaboo

By looking at your LVM configuration. – Silkaline

Great command! I wouldn't use the piping though. Getting to know information about space (at the same time you get to know about which partition your folder/file is on) is quite amusing as well :) – Jubilee

Very nice; here's the same thing done with awk: df -P /home | tail -1 | awk '{ print $1}' – Lorraine

Gotta admit, I really dislike pure command answers, can you make an edit and explain the options/params used? – Djokjakarta
