I've used my unraid server for a few years now and I've been loving it.  Then about a month ago it all started going wrong.

 

I brought a new drive to add to the array and it would not recognize it.  I realized I was still using version 4.3 so I upgraded to the latest 4.5.6 version and it recognized my drive.  Woohoo!

 

My happiness was short lived however, ever since I upgraded, the http://tower web page hardly ever works.  It works fine after a reboot, but then a short time later it will just disappear.

 

I can still ping the server, telnet into the server and access the drives through windows, so I know it is still up and running, I just can't access the admin page.

 

A bigger problem however is copying files to the server.  Copying files from the server is fine, but to the server I constantly get errors.  I can copy some files but not others, for example I just tried to copy 159 jpeg files (each around 2 megabytes) and only 5 files copied without problems.  I have tried copying from Windows7, WindowsXP and even dos, all fail.

 

Please can someone help me?

 

I am using UnRaid 4.5.6 and I have attached the syslog.

 

Thanks

The additional drive may have pushed your power supply over the edge, leading to intermittent faults under load (?)

 

Could you have disturbed some connections when adding the drive?

To be helpful, the log needs to be one captured after http://tower is no longer accessible.

 

The only time I've ever had emhttp stop working is is it is killed by the out-of-memory process run by the kernel.  Since it is typically idle the longest, it is a candidate for termination when the server runs out of free memory.

 

You can run out of memory if you are running add-ons or if you have many errors being logged to the syslog and it uses all available ram.

 

In either case, if you can log in via telnet type

ps -ef | grep emhttp | grep -v grep

 

If it shows an emhttp process then it might be DNS networking issue you are facing.  (can you get to the management page via its IP address?)

 

If there is no emhttp process, you can start it up again by typing

cd

nohup /usr/local/sbin/emhttp &

The new drive replaced an old drive, so I don't expect the power supply to be under any extra load.

 

And I have tried reconnecting all the connections many times, so I don't think it is a connection problem.

 

It does appear that the emhttp process has died or been killed, restarting it brought the web page back.  Could lack of memory also be causing the copying problems?  I have 1gb of memory, and it always used to be enough.

 

 

Help!

The amount of memory needed depends on the processes being run and the error messages being logged.  I run my older server with 512 Meg of ram, but I can run out of memory easily if I perform certain actions.

 

What add-ons are you running, if any?

 

Yes, when you run out of memory, the SAMBA processes are often also killed... That would terminate any transfers.

The only other add on I am using is the TwonkyMedia server.  And I was also running that when everything used to work ok.

 

Perhaps upgrading from UnRaid 4.3 to 4.5.6 increased the amount of memory required?

 

Thanks

Thanks for your help!  I added an extra gigabyte of memory and now all my problems seemed to have gone away!  Yay!

 

Thanks
