[mythtv-users] First myth deleted most of my recordings, then it deleted all and all schedules.

[David Kramer]

A few days ago while I was on vacation I ran low (but far from out) of
disk space.  I had a ton of old recordings.  The system deleted about
850 recordings!  I couldn't believe it.  But I still had my recent
recordings.

Today I looked at my system and not only did it delete every frackin
recording I had, including the .mpg files themselves, but all of my
scheduled recordings are gone.  I can't imagine what could have done
that.  And to further taunt me, it left a few .png files around just to
remind me of all my recordings that are now missing.

- I still have my capture card and input defined.

- I still have my storage groups defined

- I am currently running 0.22.0+fixes23893-0ubuntu0+mythbuntu3 (I can't
upgrade until I have time to upgrade the back end and all three front
ends due to schema change, so I'm still running Ubuntu 9.10 and this
slightly older myth)

- No other databases on my system had any problems, and all the myth
tables like settings, etc are in tact.

- I was able to figure out how to restore the record table from backup,
and remove oldrecorded records for shows I want to re-record if they
happen to show.  I seem to be up and running now, but.... what if this
happens again?

Questions:

- Why in the world would AutoExpire delete over a terabyte of
recordings?  And why would it delete ALL recordings?  I verified
AutoExpire was set to leave 1GB

- Are there any known events that would cause myth to delete anything
from the record table (shows to be recorded) ever, let alone EVERY RECORD?

Thanks in advance.
