Missing Disk Space [Solved]

When I search my directories using du or run disk analyzer or run ncdu -x /  I come up with about 40 gig used.

However when I run df I get 10 fold at about 407 Gig...

drive of concern -- /dev/nvme0n1p3

Any suggestions ?

I have set the reserved blocks to 5% grabbing 14 + gig , Cleared Out Cache's , Removed Orphans , Removed some old packages....

Not sure where this space is being eaten up or I am just missing something.

Any Help is much appreciated.

Thank You

Re: Missing Disk Space [Solved]

* leaking inodes, "df -hi"
* mounted into a non-empty path (boot some live distro, mount /dev/nvme0n1p3 and check the drive usage w/o any submounts like /home or /media etc.)
* space occupied in paths unavailable to to user, try "sudo ncdu"

Re: Missing Disk Space [Solved]

Thanks for the reply Seth.

I took a look at the inodes , checked the mount points ,ran ncdu under sudo and  ran a disk analyzer but no luck.

I also tried running the find command to search for potential images I forgot about but the results were cumulatively under 1G.

I am at loss for what to do next except format & start over ... but I like environment as is & don't really have the time to dig in...

--- I have been on Arch for 8+ Years / Linux for 12 ... Never had this mystery..... 

All Feedback is Appreciated !!!!!

Re: Missing Disk Space [Solved]

Thanks

I read that suggestion wrong. I went into a live usb to review & found out I am a moron.....

I wrote a script  to back up from a Plex Server to a  USB drive connected to my laptop as a secondary back up.

It is set to run every 45 minutes. So when I disconnect the drive to use  the computer somewhere else in my house the script still runs and rsync creates a directory in the same mount point adding the files to my drive. However it is masked when the drive is connected as they have the same naming conventions.

I need to figure out how to script it so it only runs when connected.

Any suggestions ?

#! /bin/bash
clear

# NAS 10.0.0.250:/mnt/Server/Media->  Oryx: 10.0.0.248:/mnt/Archive/Media/


echo -e "\n\e[37;104m ------------------------------------------------------------------------ \e[00m\n "
figlet " * Free Nas Back Up *"
echo -e "\n\e[37;104m ------------------------------------------------------------------------ \e[00m\n "


echo "------------------------------------------------------------------------------------------------------"
figlet "Media"
echo "------------------------------------------------------------------------------------------------------"

rsync -rvuz --chmod=ugo=rwx -e ssh --delete  joe@10.0.0.250:/mnt/Server/Media/ /mnt/Archive/Media/

Fixed for now / until my error gets me ....

echo "------------------------------------------------------------------------------------------------------"
figlet "Media"
echo "------------------------------------------------------------------------------------------------------"

if mountpoint  /mnt/Archive/ ; then 
figlet "Drive is Mounted"
rsync -rvuz --chmod=ugo=rwx -e ssh --delete  joe@10.0.0.250:/mnt/Server/Media/ /mnt/Archive/Media/

else 
figlet "Not Mounted"

Re: Missing Disk Space [Solved]

I usually create an empty file in the unmounted directory. Then a simple 'if file exists' statement can let you know whether or not it's mounted.
Another option would be to parse the output of mount.
