Hi Everyone, I had flashed this image “openpli-6.1-release-vuduo2-20180212_usb”

on my Duo2 with 4 tuners. It freezes while I was watching a recorded series and having 3 timers recording.

Please help

Thanks very much

Recording on what? Local disk? And define freezing? Only image? Sound as well? Did you see a spinner? Is it permanent (i.e. did you wait)? Can you still access the box via telnet when it happens?

Hi WanWizard, thanks very much for the quick reply.

The recording is on an internal 3Tb Harddisk. It freezes the image & sound and also no reactions on any depressed of the buttons on the remote. I need to turn-off & on the electricity supply. I didn’t see any spinner and it seem to be permanent. As I do not know what to do in Telnet, so did not try that.

Best Regards

Next time it happens, see if you can ping the IP address of the box.

 

If so, see if you can telnet into the box, login with user "root" and the password you have set (if any). Then type the commands:

dmesg
cat /var/log/messages

and copy and paste the last 40 or so lines of the output of each here.

 

If is is really dead, and it happens only with an heavily loaded box (all tuners active, disk active), it could also be the (capacitors of the) power supply is the way out.

Thanks very much WanWizard for the super-fast reply. I will try it out

Hi WanWizard, this time round it didn’t freeze but did an auto restart instead. Maybe I had remember it wrongly on the previous session, I am not so sure now!

The first time occurred I think was about 10 minutes of playback while 3 recordings are ongoing. The 2^nd time occurred I think was about 15 minute.

As instructed, I had done a copy of the log as per attached. Hope I had done correctly.

Thanks very much

Hi WanWizard, this time round it freezes for 1-2 minutes and restarted. I noticed the 1^st attachment didn’t succeed, I thought it did. Now I know what happen, I didn’t select “Attach This File”, therefore it was not attach on my previous report. I shall attached it in this report and also the recent one.

Thanks

The message 

ext4_mb_generate_buddy

in the dmesg2.txt means  the ext4 is corrupted

 

You can do the following

Reboot the box completly

go with telnet/ssh to the box

then

 

umount /dev/sda1

fsck.ext4 -f  /dev/sda1

 

If there are questions to repair something please confirm the questions

 

After running start the same command twice to see that everything is ok

If all is ok make a reboot with

 

reboot

I fear this is a result, and not the cause, of the issue. The described symptomes point towards a failing power supply.

Hi, Anudanan, thanks very much for the solution. Very sorry, I am rather stupid at this, may I just confirm on your instructions given are as follows,

1. Reboot the box by turning-off & on the electric supply
2. Using Putty, login to root
3. Type in the followings,
   1. umount /dev/sda1
   2. enter
   3. fsck.ext4 –f /dev/sda1
   4. enter
   5. read results
   6. umount /dev/sda1
   7. enter
   8. fsck.ext4 –f /dev/sda1
   9. enter
   10. read results, if ok, then reboot by selecting “Reboot” and not “Reboot in Enigma 2” in “Menu”

Hi WanWizard, I did try on other images and it did not show this fault.

Best Regards

Hi Anudanan, almost forgot, one last question, by doing the above, I hope it will not clear all the data in my harddisk?

Thanks again

[bumperbee]

One more question, please tell me what are the functions of these commands, so that I am able to utilize them when coming across the specific faults. Thanks again

..... Google has all the answers.

Hi WanWizard, after performing the “Ext4 Corrupt” check, I had done another test, this time it freezes at about 50 minutes of playback and also cannot telnet.

Thanks very much

[WanWizard]

As I already suspected, any corruption on the disk wasn't the cause of the issue. Again with multiple recordings running and/or multiple tuners in use?

[anudanan]

So the complete box hangs. Very strange, maybe a hardware problem

 

Did you see any repair messages during your fsck.ext4 commands?

 

Are all cables correctly fixed inside the box?

With 3 recordings and 1 playback

Yes. There are repair messages (attached) and I choose yes. I think I did another 2 times. All cables are in order.

I´ve no idea today for solving the problem.

[WanWizard]

I would try to find someone that can check the power supply of the box for the correct output levels, and is able to replace capacitors when needed.
