If you run MythTV with full disks, you should be fine as long as you don't specify "Balanced Free Space" or "Balanced Percent Free Space" disk schedulers. (Note, too, that "Balanced Free Space" is the default--because users complained that it wasn't. So, you need to change this if you plan to run with full disks.

It's not a problem when you properly configure your system. So anyone
who has read my message and who has mostly-full file systems should not
have a problem anymore--any who hadn't already have gone in and fixed
their broken configuration.

And I'm simply saying the problem isn't with MythTV, but is with the
user telling MythTV to do something stupid. :)

Yes. IMHO, that's the real problem. It's the default because users
complained that it wasn't, so it got changed from a value that was good
for people with empty, partially-used, and full file systems
(Combination) to one that's (maybe?) only appropriate for users who have
one (or some small number) of empty and several full file systems (where
the maybe means only those who are also too lazy to do a quick "mv
/path/to/recordings/1071_2014* /path/to/empty/drive/recordings/"). But,
hey, users (who don't necessarily understand the details) should make
the technical decisions about software development***.
*** "Any sane software uses UTC!" OK, now we're using UTC--so now every
time you create a recording rule that involves days and/or times or you
get or send date/time information to MythTV, you'll have to deal with
DST and local time conversion yourself. But don't worry! Now you can
record those high-value shows that air at 2am on the two DST change days
each year without having to set a start early/end late. Now everyone
enjoy this change, and go watch those infomercials!
