ReadyNAS Ultra 6 Plus Fan Noise

I have a ReadyNAS Ultra 6 Plus with the latest firmware. On a fresh boot, the fans resolve to an acceptable level. However, after running for a while, the fans are suddenly at full blast, and I can't get them to slow down with anything less than a reboot. I've tried the calibrate function, and it does not appear to do anything.

I think I've narrowed down "when" this shift from low to max speed happens. I have maintenance tasks run at 2:00am on Sunday mornings. It is later on Sunday morning that I notice the noise. I don't think this happens every week, but it does happen enough to be annoying.

Is this a known problem?
Is there a solution?
Anything I can dump to help diagnose the problem?

My feeling is, this is a bug in the firmware that needs to be addressed.

    Do I need to have something installed on the NAS to have SSH access?

    Yeah, you need this addon: http://www.readynas.com/?p=4203 (choose the "x86" version).

    When you connect via SSH, your username is root and your password is the same as your Frontview admin password.

    At the "#" prompt, type top to see the list of active processes; when you're done, hit Q to quit top and then type exit at the "#" prompt to close your SSH session.
  • I'm installing the plugin, but that needs a reboot. With a reboot, the problem will likely go away, and I'll have to wait for it to happen again.
  • Hello i know what is your problem. The WD hard drives have a big operating temperature. I used this drive in my NAS whit-out Fan, only testing purpose. The temperature was after 20 minutes 65 - 70 degrees.It was Unbelieveble.
    I wrote some ask for WD i put my money to only two HDD, but the temperature is so high. And in the specification is write is a NAS storage drive with everything lower than others. But its not true. This disk are biggest shit what i bouth.

    I never forget to WD. Before 10 years i decide never buy WD. But one year before i bought firs WD my book and there was Green WD 1 TB disk. Everithing looks good. After i put this disk in my Computer for Data. everithing looks good but sometimes the start of this disk is slower. I must wait about 5 second when i try browse of this HDD. I thing this company makes drive cheaper but no so good.

    Thax.

    P.S. Why i need that high security for password for this forum this is ridiculously.

    BYE BYE :neener:

    delanod if you download your logs what is the date in bios_ver.log ?
  • bios_ver.log says 07/26/2010 FLAME6-MB V2.0

    FiVe27 - Are these the WD Red label NAS drives?
  • The fans were wailing again this afternoon - note it's Sunday and the maintenance ran last night.

    I tried to SSH in. Here is what I get:

    $ ssh admin@192.168.0.6
    admin@192.168.0.6's password:
    Linux delano-readyNAS 2.6.37.6.RNx86_64.2.4 #1 SMP Tue Nov 12 18:53:39 PST 2013 x86_64 GNU/Linux
    Last login: Sun Feb 9 19:20:44 2014 from 192.168.0.100
    Connection to 192.168.0.6 closed.

    I seem to get immediately logged out. I logged into the ReadyNAS to see if the plugin was loaded, and there is nothing that would indicate that it is. So, I tried again to install it. That, of course, meant a reboot.

    After the reboot I had a message that a new firmware was available and that I needed to reboot to finish installing it. So, I rebooted again.

    I think I'm back to stable, but of course the fans are silent now. I tried again to SSH and I get the same response. What am I missing to get SSH enabled? I need to get that working so that I can use it the next time the fans take off.

    The user for SSH is 'root' not 'admin'. The password is initially set to be the same as the admin password.
  • The problem appears to happen once a month, though somehow December was skipped. The last three occurrences were 11/19, 1/12, 2/9. I wasn't keeping track before that.

  • Thanks! I overlooked that. I have it working now, ssh that is.

    yes, CPU fan might be in auto-control mode. check bios is a good point.
