Delete Recording From Full Disk

If your frontend crashes when you try to delete a recording from a full disk, do the following: (This only works if the backend is not currently recording.)

• Kill the hanging frontend

$ killall -TERM mythfrontend

• Start the frontend

$ mythfrontend

• Get the date and time of the recording to delete (In the "Watch Recordings"/"Delete Recordings" Section of the frontend). If it hangs again, kill it again like above and try the following:
  • Connect with the MySQL-Command-Line-Client (eg. "mysql" like in the following code) to the database usually named "mythconverg"

$ mysql -u root -p -D mythconverg
mysql> select title, basename from recorded;

• • Take into account, during the next step, that you already know the filename from the basename column
• Find the file in your recordings directory that matches the recording choosen to sacrifice

$ ls /{recordings_dir}/*_{YYYYMMDDHHMM}??[_{YYYYMMDDHHMM}??]*.nuv
# {...} needs to be replaced by the proper values (recording directory / start time digits / end time digits)
# [...] is optional depending on your version

• Empty the file, but don't erase it (erasing messes everything up)

$ echo '' > {previously_determined_file}
# {...} needs to be replaced by the proper values (the path to the file you previously determined to be the recording to erase)
# If you get a "Permission denied" error, you need to switch to a user with write permission to the file (eg. type "su" to become root)

• Delete the recording with the frontend
