[Solved] Unable to access Tower via webGUI


Recommended Posts

I had a fully working system until recently when I noticed dropped playback of some video files. A quick look at the webGUI showed some write errors on one of my HDD - WD20EARS - Time to replace it as it had crazy high LCC's anyway.

 

I had a WD20EARX sitting outside the array as a ready to go backup.... I stopped the array, powered down and swapped the HDD.

 

On startup the webGUI correctly told me my disk 3 was wrong however, I went ahead and told it to rebuild the data and start.

 

Since then I am unable to login to Tower from the webGUI. I can telnet in and see the flash USB in finder on my Mac so Samba must be working.

 

I've copied the syslog and removed all plugins and still no success... any help would be appreciated.

 

System: ASUS P8H67-M LE motherboard; INTEL i3 2300 CPU; 8Gb RAM; Sandisk 4Gb Flash drive; unRAID version 5;

Ehm...how does an HDD deliver high LCC to you? (suppose you mean Life Cycle Cost?)

Do you do maintenance on them?

 

Back to topic:

I don't want to say again how often I have been spamming the forum with "unresponsive GUI" and how FOOBAR such a situation can be if you're in a situation like this...

 

...f... I did it again.  ::)

 

We wait and hope for 5.0.6 with the updated emhttp.

 

I understand you did not reboot.

After a reboot the GUI will probably work again. Until then you're "flying blind".

 

Hopefully you have installed the clean powerdown script.

Then just wait until your drives are idling/spun down and then powerdown -r your server.

 

If you don't have the clean powerdown...well...you need assistance to stop and unmount before you can reboot the server. If not, you will most likely be forced to perform a parity check.

 

Perhaps some more knowledgeable member can help you with some linux-foo to obtain

more info from your console?

You probably have some time until the rebuild is complete...

 

Somewhere I read of a sequence how to restart the emhttp but I'm not sure if it works - never done it myself. After the first unclean powerdown I installed the clean powerdown script.

try at the console prompt

kill -1 process-pid

where you would find the pid through something like:

ps -ef | grep http

 

this would presumably restart the process

 

if you want to kill it completely replace -1 with -15 in the kill command

 

and re-launch the process by running the startup line you see in "go" script. (cat /boot/config/go) - I don't know of the top off my head where it resides -

How long has it been unavailable? It there any disk activity?

 

@ dgaschk - There is no disk activity and no disks are mounted. By the way, I reset my flash drive and go file to what is shown in your sig and I believe the line "/usr/local/sbin/emhttp&" requires a space between "emhttp" and "&".

 

Here's a copy from the console after running testparm;

 

root@Tower:/# testparm

Ok, finally some success... not without some big changes.

 

I run my unRAID as a headless media server so it wasn't until I attached a keyboard and monitor that I began the real process of discovery.

 

Turns out, when I added the new HDD my BIOS had shuffled the boot order on me as explained http://lime-technology.com/wiki/index.php/Troubleshooting "Some BIOS's reshuffle boot order, especially when a new hard drive has been added." With that sorted I moved on to upgrading unRAID to 5.0.5

 

I did a full backup of my flash drive and then reformatted and setup the flash drive with a clean install of 5.0.5. To get my plugins working (Plex/SAB/SB/CP) I had to first install the SAB dependencies using this:

cd /boot/packages

wget http://www.bibliognome.com/unraid/SABnzbdDependencies-2.1-i486-unRAID.tgz

 

I then followed the instructions here: http://lime-technology.com/wiki/index.php/Setting_Up_SABnzbd,_SickBeard,_and_CouchPotoato#Using_the_Applications to install all except CP. I'm loathed to install CP as my system is back to it's original awesomeness and from the threads here: http://lime-technology.com/forum/index.php?topic=21260.2430 I will wait until someone sorts that out.
