Though I see the problem has been resolved, I too have actively embraced the process of NOT telling customers how to put the system into redundant mode for reasons that having noting to do with theft (I make them tell me the numbers, then give them the password).
Clients- and in particular their staff- just want to put their orders in on a busy night, they could care less about the consequences (and often in times it's some random bartender or server that eventually is told how to do this). Additionally, they also mistakenly see it as fix.
Merging logs was an occasional pain in the azz for sure, but more often it was a panicked phone call from a customers days later because the owner finally came in an realized they had no credit cards/or are missing money from the bank (they were spooling- a liability I don't like to be involved with unless I have to), or they had no sales data (cuz it resided on the master) and had to have payroll down in two hours.
Thus what was probably an unplugged cable and 5 minute phone fix turned into a customer-created emergency and an hour or two in support to get everything back to normal.
I've given people who've worked for us in the past pretty straight-forward instructions- don't tell them how to put it into redundant mode, and tell customers who do know how to put it into redundant mode that it's not really a "fix" and it's in their best interest to call support, as annoying as it may be.
Sometimes should just wear protective helmets at all times
