I am new to UNRAID and just built a server that I am putting through its paces. So far, I have installed:

Beta 4.5.6

UNMENU (and several packages using its interface)

cache_dirs

 

I am still working toward full funtionality, like getting email  notifications working, but overall things are working as planned.

 

Yesterday, I installed another drive to the array and kicked off a large transfer of files (about 400GB) worth from the Sage Server to the UNRAID box using windows file manager to drag and drop files. I let the transfer run over night. When I checked in the morning, I found that my puTTY session was dead and that the file transfer did not complete. The SageTV  server indicated that it could no longer find the Tower machine. I was able to fire up telnet and get right back into Tower and the web based interfaces (UNraid and Main) were able to connect.

 

I popped open the syslog and it appears that something went haywire with the connection around Jun 11, 22:15, but the eth0 interface recovered almost immediately. The recovery though was enough to drop the connection with the windows box.

 

I am using fixed IPs for both servers, so I dont think there is anything like a DHCP lease expiry going on. Multi-hour transfers today have been working correctly, no timeouts encountered.  One thing I notice is that the transfers today from windows viewpoint seem to be maintaining a "constant" transfer rate, whereas the one last night (before the problem) was very spikey (bouncing between 0 to 15MB/s to 0). I verified that the files last night and today are being dropped onto the same disk.

 

Any thoughts or past experiences with this sort of issue?  BTW, I have attached the syslog from last night.

 

Thanks in advance,

DQ

There have been a few other occurrences of this Realtek networking issue, but no resolution yet.  Check these 3 out:

* http://lime-technology.com/forum/index.php?topic=3633.msg31882#msg31882 and my reply here

* http://lime-technology.com/forum/index.php?topic=3236.msg27460#msg27460 (midway in the post) - the same network issue, but mixed in with drive and cable issues

* http://lime-technology.com/forum/index.php?topic=1244.msg16147#msg16147 - a much older unRAID version and kernel release, but the same issue; hints that it may be a Realtek driver bug; some additional driver discussion follows later

 

This is obviously not very helpful, but that is where it stands currently.  Something you may want to consider, if this continues, is to install a network card, and use it instead (disable the onboard NIC).

 

By the way, welcome to unRAID!  and thanks for supplying a syslog!

Thanks for the links. I was kinda thinking that the onboard ethernet was the issue. The one post that pretty much sums it up is "Welcome to the world of Realtek".  If the problem happened once, it will happen again, so the NIC must be replaced. 

 

Before posting, I had stopped by my local Fry's but they were unfortunately out of Intel Pro1000 PCI nics (everyone must be building UNraid boxes with Realtek nics onboard  ). Your post affirms that I am on the right track and a trip to MicroCenter and CompUSA is worth doing before going to the 'Egg.

 

Thanks for the feedback, I appreciate it.
