My mythtv box is down: it is not bringing up the UI.

DETAILS
======
Last night I attached a smaller (500GB) USB drive to the box to move files to the larger USB drive. Because there were problems accessing the USB drives, I rebooted the myth server.

To my chagrin, it booted up to a "Select your preferred language" screen. Then it started to get ugly. The next screen: "No UPnP backends found" followed by 'Database Configuration'. This 2 page menu indicated that "myth can not connect to the database". I'm fairly certain that I am using the default password:



The boot hard drive seems to performing an excessive number of reads.


QUESTIONS
========
Has anyone observed these symptoms before and diagnose the root cause? My search of MYSQL in the forum did not produce any insight.

I am hoping to avoid reinstalling mythtv because I have a lot invested in configuring the system. Thanks for considering my posting.

I have seen that happen when the boot drive is full. Try df -h to see if that is the case.

@brfransen: nailed it. Good job.

Please advise what was done to resolve this: I suspect something was deleted, but not really sure what should be removed.

Most likely it is some log file. Check /var/log/ and /var/log/mythtv/ But don't just delete blindly. Look for the largest files and see if there was an error repeated over and over that caused the file to grow in size so much. You could also check and remove any old pkg from /data/var/cache/pacman/pkg/ to regain some space.

@Britney: your guidance has returned mythtv to working status: Thank you. I need to analyze the log files and determining why their size exploded. A cursory review of the 60MB log files show that the dominant repeated message is of the type:



Not sure what I could have done to cause this.

After moving the logs off-disk, 1.6 GB of space was recovered.

[root@mythtv /]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda1 4.9G 3.1G 1.6G 67% /
none 996M 0 996M 0% /dev/shm
/dev/sda3 181G 159G 13G 93% /myth

Delete Files By Size Recursively
=====================

It's wise to list the files first to avoid shotgun deleting:


THEN delete.

I always give myself a root partition of 20 GB instead of the standard 5 I think you can use Gparted to non-destructively increase your partition size but check on that before you kill your box.
