By disabling the rrd on the system dataset it means the rrd data is being stored on the boot device. I'm betting your boot device is also USB, so nothing gained there. You simply moved the writes from one USB stick to another.
Also, by moving the syslog to a remote server it does not disable logging on the local server. The remote server option simply allows a mirror of the logs to go to a remote server. Read the manual on the setting. It says "IP address or hostname of remote syslog server to send logs to; once set, log entries will be written to both the console and the remote server". Unless this is inaccurate in 9.3 (I haven't checked in 9.3 specifically since I don't have a syslog server at home) I think you've changed nothing. :p
I do not know how to disable them in some elegant way, and the reason for my post that you are claiming is offtopic is because you're doing things that aren't going to end well and aren't doing what you think they are doing.
Car analogy: You are asking how to put gas in the gas tank while holding a gallon of Diesel fuel and standing next to a car that only takes Gasoline. Should I tell you where to put the gas in the tank and watch you blow up your engine or tell you that you shouldn't use that fuel in that car? I think the latter is a better option all things considered, and I'd like to think that you'd take my advice and realize that what you think you are doing and what you *are* doing aren't the same. Then you'd thank me for saving you from problems later (and you *will* have problem later if everything is on USB, which is exactly what I tried to say in the first post).
So I'll kindly ask you to tell me what you think *I* am missing about this conversation since you've told me I'm off topic.
Well you comment on things you have no detailed knowledge of and not answering my main question. Dont get me wrong I would appreciate opinion on this matter, but it seems you are mostly guessing.
Because syslog logs are apparently not stored permanently when they are not stored in system dataset. They are only in tmpfs filesystem. Regarding reporting DB I dont know, because I can see old stats. I can investigate further. But there are no big / repeat writes to any of USB sticks, boot one gets typically about 1 MB of writes per hour.
Except that there are only Samba status data and backup of settings when changed, nothing else. I doubt the system will somehow fatally crash when USB system dataset stick will die, there is nothing important on it. It is lowcost NAS and I am trying to use USB for this. If stick dies too soon, I will buy some cheap SSD.
But I want to eliminate all writes I can and apparently nmbd is main source of them. BTW it would be ideal if you can choose to have Samba status data only in tmpfs, in my configuration it would be OK.
