Support knows how to rebuild the OS from scratch w/o touching the data volume, but I don't.

Look further into here.  My cache is ~50M, and lib is 384M.  Everthing else looks reasonablely close.

You can use:

du -xhd1 /

and then work your way to find the file using up space, it's likely a log file or database file related to some app that's installed.

 

Full root is not cause for alarm in terms of data loss, it's a separate volume and if you can't figure out what it is I would recommend contacting support

Paid support is certainly a good option for this.  Although there is little risk of data loss, if you don't address it promptly the NAS can become unresponsive (either the web ui, or file explorer access, or both).

 

It might not be a log - what apps do you have installed?

I'm not sure what you mean by the "data log".  The apps are supposed to be installed in /apps.  That's a mount point for /data/.apps, so they are supposed to use storage in the data volume.  But some apps aren't correctly written, and use a lot of space in the OS volume.

 

LogAnalyzer is one of the ones that uses OS volume space, so you should start by uninstalling that one.

 

I've seen several folks post issues with linux-dash not working, but I haven't seen a root cause for that posted here - and I don't know if it is using OS space or not.

 

Recoll is really no longer needed, since indexing/search was added to the web ui in OS 6.8.

Use the 

du -xhd1 /

idea, and see if it leads you to a particular file or folder.

 

What firmware are you running?

Hi Steven

Running firmware V6.9.1, I have now also un-install all 3 apps that i had installed come down from 84% to 83%. Is there any way to reset the whole system to factory default and save my data on the hard drives if i remove them?

Re: System volume root's usage is 84%. This condition should not occur under normal conditions. Cont

So i went into lib directory as this was showing as 2.1G
and the offending file was a 1.5G mysql database file left behind i do believe when i prevously had mysql server install i geuss. Now back down to a healthy 1.5G root usage.

 

root@Home-Server:/# du -xhd1 /
4.0K    /mnt
4.0K    /srv
30M     /lib
40K     /root
31M     /frontview
4.0K    /boot
32K     /tmp
4.0K    /selinux
11M     /etc
949M    /var
485M    /usr
16M     /opt
4.0K    /media
11M     /sbin
6.0M    /bin
16K     /lost+found
1.5G    /

 

Thankyou to everyone for you help i can now put this down to being resolved.

Regards Paul
