#1188 closed defect (wontfix)

Recording shows when no disk space available

Description

I couldn't find any ticket about this or similar issue and created new one.

Just found that my storage was almost full but mythbackend still started recording and died when disk became full. I know for sure that before this new LiveTV backend refused to start recording when there was enough space available. Looks like something missing with autoexpire checks or free disk space calculation doesn't work right.

I upgraded to [8821], then checked free storage space (about 1.4 GB) and started backend

cougar@zero:~> mythbackend -v record -l mythbackend.log
Killed

Storage became full and because of this mythbackend exited with "Killed" message.

I removed some repeating errors and attach this logfile to the ticket.

Hmm, this might be similar to [1076]. Can we get a backtrace (FAQ entry)? It's not a good thing when mythbackend crashes. I assume that this should be fixed by finding the screwed up autoexpire check or free diskspace check, but cancelling the recording and printing a logmessage is better than crashing.

Whoops, meant #1076. Sorry.

Any specific debuglevel that I should use here? I just tried to use gdb with [8835] (compiled with --compile-type=debug right now). I don't know how this exits but gdb doesn't give any backtrace.

You need to allow the auto expiring of your recordings; and set a free space allowance if you use the disk for other purposes.

The crashing part will be fixed when #1076 is fixed.
