OMV Web front-end is not working (Segmentation fault?)

G90210 · 26. Oktober 2016

Hello everyone,
I am using OMV on Banana PI (SimpleNAS debian wheezy) for more than 8 months. Also I have very limited linux knowledge, so the issue might be obvious.

Everything has started with an issue with DNS server. But after some googling, experimenting and (eventually) reinstalling resolvconf it was resolved.

Now I have issues while accessing OMV front-end via http (port 80) - the server is not responding. I do not have any issues accessing SSH, SMB shares or Transmission Web GUI, but I am also not able to access ownClowd (SSL).

I have tried omv-firstaid (2) Configure web GUI, but after entering all the ports etc. it ends with an error

Code

Updating web administration settings. Please wait ...

Also, netstat does not return openmediavault

Code

Reinstalling openmediavault or nginx (apt-get --reinstall install openmediavault) has not helped either - issue still exists.

Code

root@denver:~#  service nginx restart
Restarting nginx: Segmentation fault

Please advise how this can be fixed
Thanks

Did you install the flashmemory plugin? If not, I am guessing your SD card is failing and there is no way to fix that. If you copy the card, you would transfer the problem to the new card.

I don't recall specifically installing it, but I see it in the list of installed packages

Code

root@denver:~# dpkg --get-selections | grep -v deinstall
....
openmediavault-flashmemory                      install
....

I would look through logs in /var/log for a better explanation then. dmesg is very helpful.

Is there anything in particular i should be looking for? The following lines looked suspicious to me:

Just to add - for some reason I am now able to access both OMC Web interface and ownCloud, although I did not make any further changes (not even rebooted), so I would like to understand better why this was happening (and I am not sure if it will continue working after reboot)

ryecoaaron · 28. Oktober 2016

None of those logs tell me anything is wrong. If it is working now, I don't have any ideas. Maybe try a different SD card??

G90210 · 21. November 2016

Ok, it is no longer working after reboot. I now have bought a new SD card - what is the fastest/easiest way to transfer all the settings?

Also - how to make sure that the same will not reoccur after I will move the settings (maybe there is something wrong with the setup)? Thanks

You can't. You have to setup everything again.

I don't know.
