All I can say, here, is that:

d) Only you can decide whether you're comfortable storing your MySQL (including MythTV/mythconverg) data on a file system with barriers disabled--and, your backup strategy and the level of importance you place on the data and such will come into play when making that decision.  But, I do recommend searching the 'net and doing your own research before making the decision.

Sorry for the complete lack of a recommended action, but I definitely don't want to be the one who's at fault if someone were to experience a problem in the future due to disabling barriers.

Hi.

What is the risk of disabling barriers if the system is connected to a UPS?

My UPS software initiates a clean shutdown (not sleep or hibernate) and the BIOS autostart feature kicks in when power returns.
