View Full Version : Disk Usage Analzyer Error?

June 24th, 2010, 07:37 PM
I just did a new install with Ubuntu 10.04, then add Mythbuntu. I have 80g hd internal. I have a 20g / partition, 55g /home, 5g swap. I also added a 1Tb external usb drive. I had trouble with the permission on the 1Tb drive because it was NTFS. I reformatted it to ext3 and was able to fix the permissions so myth could read and write.

I have all the myth storage locations set to this external drive because there is so much space. I have started to get some shows recorded and now have 30-40gigs of video.
Disk Usage Analyzer start to give me warnings about space. I double checked to comfirm that myth was writing to the external and it was. I even removed 16gb from the /home directory and it still shows 100% usage even though it also says that there is 900+GB of free space.

It is like Disk Usage Analyzer doesn't count the disk space on the external it even though it know is it there. It is counting the data on the external against the 55gb on the /home.

I have the external drive mounted to /media in the /home directory could it be part of the problem?

I searched the forum for problems like this but it seems like most people are out of space and need to clear it out. I have plenty of space and it doesn't think so.

Any help would be greatly appreciated.

Ok well looking at this I am not sure why my / is filling up. Once before I had myth keeping huge log files of several gigs. What do you recommend?

Try investigating it with the 'du' command.

sudo du -sh /*

or better still

sudo du -s /* | sort -nr

I am not sure why but the mythtv logs are 6gigs. It seems there are several 1.2 gig backend log files.

6GB is quite a lot for logs, but I am not familiar with mythtv. In Ubuntu desktop, the logs in /var/log rotate. They get compressed after some time and deleted after 30 days. I've seen my /val/log reach 15MB, but the current size is only 7.5MB.

whats the output of

ls -l /var/log/mythtv/

logrotate usually runs at 6am (or around that time) and if the system isn't running at that time then the logs aren't rotated.

To the op , you can delete the old log files. Dependant on the options set for mythbackend myth can create very large log files (on my backend with the option -important,eit the backend creates 30-40mb logs per day).

something looks like it is broke. What is going on in the mythbackend.log file.
