OS 6.6 on Ultra 6:. Not ready for prime time? Do I need more memory? Or...?
TL;DR version: OS 6.6 is worryingly unpredictable/unstable on my Ultra 6. Do I just need to expand the memory past the stock 1 GB, or is OS 6 still not ready for prime time, at least on these older b...
Final update (I hope): I re-ran the upgrade from 4.2 to 6.6.1. The NAS has been working perfectly for over a week. What was different this time? (a) all disk were in place already, so no RAID expansion was needed; and (b) I went straight to 6.6.1, not 6.6.0.
I did order more memory, but haven't installed it; I'm still running the stock 1 GB. I wanted to replicate my previous issues first so I could verify whether increasing RAM alone would fix it. But the box has resolutely failed to show any issues at all: no hangups, no unexpected slowness, no failures to respond. I've tried things like running a scrub while launching backups and hitting the NAS with clients, and the system reacted more slowly when all that was going on, but even so: it all worked, and the scrub of 8.8 TB finished within 48 hours (as did the initial full backup, before I started the stress test). Incremental backups run as quickly now as they did on OS 4.
So I either had a subtle corruption during the initial upgrade, or stuffing two new disks in and expanding the volume triggered the problems. But it wasn't low RAM, apparently, and OS 6 seems to be running fine despite my best attempts to break it. I'm going to label it "bug report closed: cannot replicate."
As for the apparent mislabeling of the System and CPU temperatures? I edited /etc/frontview/sensors/ULTRA6.conf and swapped the "System" and "CPU" labels for temp2 and temp3, ran "systemctl restart readynasd", and now the readings in the web UI match the values I expected from version 4.2 (I got the idea from this thread: <https://community.netgear.com/t5/Using-your-ReadyNAS/ReadyNAS-4200V2-OS6-6-1-fan-control/m-p/1219655#U1219655>).
Can you send in your logs (see the Sending Logs link in my sig)?
Logs sent! Big backup is now running, and memory looks like this:
KiB Mem: 1003856 total, 968444 used, 35412 free, 2448 buffers KiB Swap: 2093052 total, 17844 used, 2075208 free. 492368 cached Mem
I also have upgraded my Ultra 6 to 6.6.1 - CPU temp is locked at 35 degrees and doesn't budge. The system temperature is varying over time based on conditions - but seems incorrect.
HDD temps are 35-36 or so
CPU doesn't move from 35
System at 47-50...
I found a file:
/etc/frontview/sensors/ULTRA6.conf
This is my conf. CPU temp is everything low (max 15-16 celsius), i'm sure it is wrong. (heatsink is warm-hot, with Arctic MX4 paste and a 40x40x10mm Noiseblocker XM2 fan, what is plugged the connector near chipset):
