| Post subject: | Force automatic expire |
I'm having a problem with R5F27 and my Xbox frontend. The frontend hangs if it's displaying the program list and a program is automatically expired. As a workaround, I would like to force the backend to ensure that there is 20 hours of free space. I would schedule this to happen at 4am and then automatically reboot the Xbox shortly after. By doing this, there would be very little chance of having to auto expire a program during the day - thus avoiding the problem. Is there a way to force the backend to auto expire programs? |

If I set AutoExpireExtraSpace to 40 will the expire process pick this up at some point and clear out the necessary disk space? Then I could set AutoExpireExtraSpace back to 5 and not have to worry about auto expire happening for a while. Would this work? |

I looks like the expire thread will run every 10 minutes. I think that the only thing that I need to figure out is how to signal the backend to reread the setting after the database is updated. Any help on this? |

The solution: 1. Set AutoExpireExtraSpace setting to 40. 2. Copy /etc/init.d/mythtv-backend to /usr/local/bin 3. Modify /etc/init.d/mythtv-backend to add the --noautoexpire arg. Cron job kicks off a shell script at 4am which does the following: /usr/local/bin/mythtv-backend restart sleep 1200 /usr/local/bin/mythtv-backend restart On the frontends, a cron job reboots the machine at 4:30am. |
