Spin-down problem and how I resolved it
Since the Spin-down option was built in it has been never working properly. After each and every Update (wich I appreciate a lot by the way) I've been trying to activate this function always with the...
I don't have many of the log files you reference (and don't have /etc/rsyslog.conf either). Normally the NAS logging is done with journalctl.
I am thinking you might have installed rsyslog manually - is that the case?
that is an interesting point. But I haven't installed rsyslog manually, may be it came with some Netgear apps as a dependence, I did test some of them.
by the way journalctl also writes to the root aka md0

There is (or was) a log monitoring app that installs rsyslog. I suggest uninstalling any apps you no longer use (and if you've done that already, manually uninstall rsyslog). Some of them can destabilize the NAS (particularly when upgrading firmware).

Yes of course. But you got spindown to work without changing journalctl. My recollection is that Netgear set up logging to defer writes (at least to some degree) in order to avoid spinup. There are some posts where they say they said that they made some adjustments to flushd.
FWIW, I wouldn't have made your mods - at least not all of them. /tmp is rarely used, so I'd leave that alone. Writing logs to RAM sounds like a bad idea to me, as you'd likely lose them when you need them the most. I think tallylog is normally updated when users attempt to log in - which likely will spin up the disks anyway. So I wouldn't be inclined to fiddle with pam or tallylog either.
But it'd be interesting to see the results of making each mod individually (after removing rsyslog, and seeing what difference that makes).

I don't have any apps installed, but the rsyslog was still active. For now I just deactivated it with systemctl disable rsyslog.

So, without rsyslog running:
Jun 14 14:26:49 NAS noflushd[30958]: Spinning up disk 1 (/dev/sda) after 7:45:55. Jun 14 14:26:49 NAS noflushd[30958]: Spinning up disk 2 (/dev/sdb) after 7:45:52.
that is OK
But hier I still have some questions
Jun 14 14:56:50 NAS noflushd[30958]: Spinning down disk 1 (/dev/sda). Jun 14 14:56:53 NAS noflushd[30958]: Spindown of disk 1 (/dev/sda) cancelled. Jun 14 14:56:53 NAS noflushd[30958]: Spinning down disk 2 (/dev/sdb). Jun 14 15:09:11 NAS noflushd[30958]: Spinning up disk 2 (/dev/sdb) after 0:12:16. Jun 14 15:32:12 NAS noflushd[30958]: Spinning down disk 1 (/dev/sda). Jun 14 15:32:15 NAS noflushd[30958]: Spinning down disk 2 (/dev/sdb). Jun 14 16:17:13 NAS noflushd[30958]: Spinning up disk 1 (/dev/sda) after 0:44:58. Jun 14 16:32:15 NAS noflushd[30958]: Spinning down disk 1 (/dev/sda).
I think, it may be caused by the journalctl or some other logging daemon, at this time of the day the was nobody at home using the nas
->Writing logs to RAM sounds like a bad idea to me, as you'd likely lose them when you need them the most.
the RAM thing was actually temporary and used only for a daemon.log, I needed a log that wouldn't be written on the root system for the noflushd. At this time I have no knowledge of the journalctl.
For the tallylog - I'm sure it was updated due to some cron jobs or some other activity from readynasd, The configuration for tallylog is in the pam.d file for 'frontview' service. I don't know what is it, but the tallylog was written without any user been logging in.
So my suggestion is sitll to transfer all kind of system stuff aka logging to the USB and the /tmp to the tmpfs drive.
