Shortly after noon local time today, while I was using TeraCopy (high-performance batch copy utility) under Windows 7 to push a large number of large files to my unRAID server, the unRAID server disappeared off the network.

 

When this happened, I tried hitting both

http://tower

and

http://tower:8080

from a browser, but no luck.

 

The LEDs next to the network port on the unRAID box were still active, so I unplugged and replugged the cable, though I wish I wouldn't have done that, since it complicated the system log a bit.

 

The unRAID box itself was still alive, and I was able to log in through the console and successfully browse

/mnt/user

before putting a copy of my system log on the flash drive.

 

A click of the power button got me a beep, but after five minutes or so, it was still alive.  The

powerdown

console command returned immediately and didn't appear to do anything, either.  Eventually, I used the

poweroff

command, which appeared to get a lot of things stopped before the box powered itself off.

 

After rebooting, the unRAID server appeared on the network without anything else being rebooted or power-cycled, and was perfectly happy.

 

I don't see anything all that interesting in the system log, but I'm no expert yet, either.  I'd appreciate other opinions!

How long did you wait? I've had some rare situations where my server randomly cannot be accessed via anything but telnet. It always resolves itself in a few minutes, and I see no errors in log. This has happened maybe 3 times in ~2 years.

 

If it happens again, I suggest waiting 5-10 minutes before attempting to restart the server.

I certainly didn't wait longer than five minutes, so if it happens again, I'll give it more time to come back on its own.

 

Has anyone else experienced this?
