OS6 now works on x86 Legacy WARNING: NO NTGR SUPPORT!

I have installed 6.0.8 on Ultra4 and everything seems to be fine, front page reporting is broken, but other than that everything is fine. Even iSCSI is working great ( from windows 7 clients using mutual CHAP).

I have a bit "advanced" problems - please note that they should not stop anyone from using OS6 on older gear, they are just plea for advanced help:

1) I don't seem to be able to stop the NAS from "calling" home, i ran apt-get purge on some packages as recommended earlier in this thread, but i still get this:
root@poligonas:~# netstat -tan
tcp 0 0 192.168.1.72:35191 206.16.42.179:443 ESTABLISHED

Anyone got clue how to get rid of this stuff?

2) Power efficiency of OS6, it just seems to be chewing a few watts more than 4.2.24. While i don't really care about disk turning off, i decided to dig deeper and didn't like what i've found:
After running
pidstat -t -w
i saw this:

Yup, you see it right, it is readynasd waking your CPU 800 times per second and not letting it go to deeper sleep states.
And unfortunately those threads are not doing anything important either, they are using technique that has fallen out of favor in any power use aware programming for years now:
strace -r -p 1734
Process 1734 attached - interrupt to quit
0.000000 restart_syscall(<... resuming interrupted call ...>) = 0
0.006898 nanosleep({0, 10000000}, NULL) = 0
0.010366 nanosleep({0, 10000000}, NULL) = 0

Yup, that is nanosleep for 10ms burning extra electricity.

4.2.24 had none of this, looking at vmstat you could see dozens of interrupts/wakeups instead of thousand+ on OS6 box...

Question is - can we get rid of all this madness? I can't dig deeper without gdb and powertop, but maybe some Jedi will have a clue wth is going on with those 8 threads?

3) Anyone got idea why Netgear is using acpi_idle instead of intel_idle? while both are using mwait in idle, intel_idle can go deeper. I wonder if anyone tested custom kernel with intel_idle, is it working?

Which process is it?

# apt-get purge busybox-net-tools
# apt-get install net-tools
# netstat -tanp

Yes, you should find that the next release behaves much better in this regard. We should have a beta very soon.

Just a simple oversight. intel_idle will be enabled in the next release as well.

AWESOME, thanks a lot for keeping community updated. Looking forward to these low hanging fruits of power efficiency. OS6 is really shaping up.

6.1.1 beta firmware is available if you would like to try it: http://www.readynas.com/forum/viewtopic.php?f=154&t=72282

Took the plunge and have 6.1.1 beta running on my Pro 6. Mostly all ok. Fans, temps and temp rrd trends still don't work on Pro 6 without some mods/patches.

Have some problems moving the apache port from 80 to 8080 as ports.conf no longer seems to be recognized but other than that all seems good.

Edit: apache2 ports are fine and can be set. I had a typo! Have noticed one problem though: Network config from frontview gives an error.

Edit2: Network trending isn't working in frontview performance monitoring either on a Pro 6.

That's the ReadyCloud service.

systemctl disable rcbrokerd

should take care of it. There's supposed to be a way to disable this from the UI, but it doesn't appear to be straightforward at this point.

ran

root@poligonas:~# systemctl disable rcbrokerd
rm '/etc/systemd/system/multi-user.target.wants/rcbrokerd.service'

but i can still see the process of "rcbrokerd". Killing it is not working either, it restarts immediately :)

Oh, right, that's the saved state and wouldn't take effect until you reboot. For immediate action, you need to add "systemctl stop rcbrokerd".

6.1.1 beta on Pro 6 problems so far:

1) Network card is not recognised in frontview - gives an error and shows a blank screen and hence cannot change any network settings
2) Network data does not show in the performance trend
3) Cannot download the logs

Plus the usual problem with temps and fans

Does anyone know if I can switch back to 6.0.8?

So some good news update
It seems sabnzb is added to the utility list of netgear yay!
apt-get update
apt-get install sabnzbd
will install: libcgi-pm-perl python-yenc libcgi-pm-perl python-yenc sabnzbd
Version? sabnzbd_0.7.13-0rnx1_all.deb Awesome!

Get:2 http://apt.readynas.com/packages/readynasos/ 6.0.8/apps sabnzbd all 0.7.13-0rnx1 [2695 kB]
Before you update go to sabnzb config then select General tab.
At SABnzbd Port change to 2708 and save changes then restart sabnzbd.
After Official Netgear install it will show up in apps panel and be able to launch it from there
