Hi all.

I got everything to work and suddenly i get this error: System volume 'root' usage is 83 %. This condition should not occur in normal conditions. Please contact technical support.

I have seached the forums and tried the different suggestions made but i cannot find the culprit..

I need some assistance with this please. I do not want to start over all again.

if i do df -h in root i get:

root@Hoa-Nas-Pro:~# pwd

I read in some post that Logitech Media Server could make a mess so i tried to uninstall it. No Success! Same error that some other user wrote in the forum about.

Since i run 6.3.5 on a legacy nas my options with support is.... well.... non existing?

I can offer full access whenever to the server if that helps. With vpn. or if you prefer whatever other way of conneting.

I REALLY need support on this.

1: find the reason why root is almost full

2: get rid of Logitech Media server. (Minor priority)

Regards

Hans

btw, my other posts about cron and such are solved. i will update them to that status.

Success! 

Found this: datadir = /var/lib/mysql

Changed to: datadir = /data/mysql

Stopped mysql server.

Copied all content in location 1 to location 2.

Made sure that all rights where correct.

Deleted all content in location 1.

Started Mysql server and checked df -h:

Hi all.

Update:

In root i have a folder called run, in that folder there is a folder called nfs4 that contains aprox 1gb of various data.

If i do df -h that folder is not on the os partition..

/dev/md/data-0 14T 5.5T 8.2T 40% /run/nfs4/data/Audio
/dev/md/data-0 14T 5.5T 8.2T 40% /run/nfs4/data/media
/dev/md/data-0 14T 5.5T 8.2T 40% /run/nfs4/home

Right?

Cannot find whats filling /dev/md0 4.0G 2.8G 940M 75% /

Having a hard time understanding this......

It seems like its the sql database tha eats up the space.

Is this normal?

Can i move the mysql database to my data drives?
