Volume: System volume root's usage is 83%. This condition should not occur under normal conditions.
Hi all,
Got a strange warning about 83% fullsystem root.
Rebooted because RNnas was crashed/hung.
Btw, why isnt rootfs showing up any more?
Logged in via ssh and mounted root as mnt.
Did: du -hsx /* | sort -rh | head -10 and got the following report which looks normal??
root@Hoa-Nas-Pro://# du -hsx /* | sort -rh | head -10
du: cannot access '/proc/12371/task/12371/fd/3': No such file or directory
du: cannot access '/proc/12371/task/12371/fdinfo/3': No such file or directory

Hi all and thanks for all the ideas.....
I deleted mnt btw...... Nothing works now...... :smileylol:
Just kidding, understood that you missed the part about mounting in mnt.
Anyway, found the issue, update to plex that did some buffering into /var/tmp !!
Problem solved by installing new version of plex.
Now i'm back to 35% in os partition.
Kudos to rn_enthusiast and StephenB !
ps, i select my own post as solution... :-)

tmpfs 1020239 1 1020238 1% /data/RNXconfig/snapshotHi viperhansa
The OS (/) uses BTRFS. Therefore, you won't see inode count when doing df -i. That is normal. The only thing I see abnormal here is /mnt
Why does it have 1GB of data in it? It should be empty.
/mnt isn't used as a mount point for the NAS so unless you have something manually mounted to /mnt.... this folder needs to be cleared out. Move the stuff in /mnt to somewhere on /data or delete the stuff in /mnt if you don't need it.
Also... Your OS (root volume) isn't full right now so I wonder if it was some kind of /tmp data that might have caused it (solved by a reboot as /tmp is cleared on reboots). Given that you have data in /mnt which is not normal - I wonder if you running any kind of customised scripts on the NAS? Or maybe your FTP users put data in the wrong place - like /tmp possibly. Something like that.
Anyway, still clear the data inside /mnt...

I think rn_enthusiast missed this bit. Definitely don't delete stuff in /mnt!
The purpose of mounting root as /mnt is to allow you to search the OS partition itself (seeing what is actually in /apps and other mount points). Your commands to explore the space should have been done in /mnt.
As rn_enthusiast says, you need to analyze free space and unallocated space using btrfs tools.

Not completely sure what you mean by this. But when you first log into the NAS, you are in /root - which only has hidden files. If you then enter cd // you will see the usual folders. This is not new behavior.
Ahh yes I missed that part. Thanks for pointing out :)
