I have noticed same strange things happening since I updated to the most recent FW version. Heard the fan go to high RPMs a few times, didn't think much about it since I knew I was giving the drives a workout by deleting an good hunk of data. Then I went to update the smb.conf file and thought I had messed something up (see post in another topic.) But since I recovered from that affair, I have been watching things more closely now.

What I have noticed is that my NAS will drop off the local network ... no blue LED lit, and no connection when I look over at my router. When I go to hit the front-panel switch to reboot, I can feel the unit is very warm and the reboot does not immediately re-enable the network connection after all is back "up." I have to power it off and let it sit before a reboot regains the LAN connection. Sounds like a heat problem to me.

While I write this, my NAS is powered off because it just did it again. However, this time I was logged into the unit via web interface and noticed on the status page that the temperature reading said 0 F / 32 C. I went over to the unit itself and it was in fact very warm and the fan was barely (if at all) turning. I then tried to reboot the unit from the web interface. It completed the reboot, but alas no LAN connection. So now I wait for things to cool off before trying to get the unit back up and running.

Anyone have thoughts?

**Update**

Unit is now currently back up and running. Reviewed my syslogd file and noticed these lines:

Code:

Feb 10 17:07:12 NAS user.notice kernel: egiga0: mac address changed
Feb 10 17:07:12 NAS user.notice kernel: egiga0: link up<5>, full duplex<5>, speed 100 Mbps<5>

Interesting to note is that the unit is connected to a gigabit capable router with cat5e cable and had been connecting perfectly fine in the past at the higher speed. So this says the lower speed was auto-negotiated, which matches the setting I have via the web interface. I'm puzzled about the mac address change though.

Also...I used the web interface to force the internal fan to always be on now. I'll continue to monitor things.

Anyone else have ideas or thoughts or suggestions of other things I should do/try?

** Follow-up **

I read in another topic that people experienced temperature related problems (or more correctly, fan control problems) if they were running both the NTP deamon and fancontrol. Since that is my case, and I have the NAS box sitting in the far corner of my office where any fan noise is pretty much drown out by music and/or TV, I elected to have my unit simply have the fan permanently running. Temperature is reported as 98F under idle conditions, with peak of 104F when serving up MP3s.

And I adjusted my ntp configuration which has eliminated messages about 'frequency error 512 PPM exceeds tolerance 500 PPM' that I had seen in my syslog file.

Code:

/ffp/bin/ntpd -x -g -f /ffp/etc/ntp.drift

However, I still have the issue where my NAS box upon reboot drops out of 1000Mbit/s and auto-syncs at 100Mbit/s. (see below) Next bit of sleuthing will be to swap cables with a known working gigabit device and see if that resolves the issue. According to the web interface, the network is set for auto speed.

Code:

Feb 11 17:25:04 NAS user.notice kernel: egiga0: mac address changed
Feb 11 17:25:04 NAS user.notice kernel: egiga0: link down
Feb 11 17:25:04 NAS user.notice kernel: egiga0: link up<5>, full duplex<5>, speed 1 Gbps<5>
{snip}
Feb 11 17:25:04 NAS user.notice kernel: egiga0: link down
Feb 11 17:25:04 NAS user.notice kernel: egiga0: link up<5>, full duplex<5>, speed 100 Mbps<5>

BobE, did you ever identity the cause of your temperature issue? The reason I ask is that I have recently encountered some of the same issues. It started with the primary server reporting a temp. of 32F / 0C. After several restarts I decided I was having hardware problems and moved the disks to a second DNS-323 unit. When that unit started showing the same error I knew it was not mechanical.

My systems are running firmware 1.09 and I has recently installed FFP on the primary unit. I have had the same basic FFP system running on the test system for a month or more with no problems. On both system I start ntpd services and get the correct time at startup. The systems do not deal with drift concerns and I do nothing with controlling the fan or even reporting the temperature.

In my case the temperature issue stopped when I disabled ntpd. I have had other problems during restarts and loss of connectivity, but these are probably operator issues while reconfiguring the two systems. After a period of normal operation, I may restart ntpd to see if the problem returns, but I have other things I would like to be doing.

You can run NTP via a cron job a couple fo times a day rather than leaving he daemon running and you won't have these issues.
