problem after installing openmediavault-flashmemory plugin

emsic · 6. Mai 2015

Did it according description. Now instead of webgui I got this on screen

Code

Error #6000:exception 'OMVException' with message 'Failed to open file (filename=/var/cache/openmediavault/cache.omvwebguilogin_js.json, mode=w+).' in /usr/share/php/openmediavault/util.inc:168Stack trace:#0 /usr/share/php/openmediavault/htmlpage.inc(163): OMVJsonFile->open('w+')#1 /var/www/openmediavault/index.php(41): OMVHtmlPageAbstract->render()#2 {main}

Thanks, but still the same, no Web GUI

Code

at least I believe so. I see the connection in the router.

davidh2k · 6. Mai 2015

Hast du in ner guten halben bis dreiviertel Stunde Zeit für ne Runde Teamviewer? Dann würd ich mal direkt drüber schauen, mir hatte das flashmemory plugin auch ins System gehackt, ich konnte es fixen, wobei wir nicht rausgefunden haben wieso der Fehler entstanden ist.

Gruß
David

bobafetthotmail · 6. Mai 2015

Write (if you are already Root you don't need to write sudo)

Code

sudo rm /etc/init.d/fs2ram

then

Code

sudo reboot

This will delete the fs2ram startup script (the program controlled by that plugin, and also the one that is crashing the webinterface, as it relocates folders but it seems to have screwed up this time), and ask the device to reboot, on reboot the webinterface should be back to normal (and the plugin will be broken, of course).

Then reinstall the plugin and see if it still fails this way.

Most other actions fail horribly because fs2ram has moved some folders around and other components of the system can't work properly (dpkg and apt-get are among them).
Again, after this procedure every other component should work fine again, as fs2ram was not started again on reboot, so their stuff will be there.

Btw, for others, I did warn of possible issues about fs2ram screwing up and crashing the webinterface. And that this procedure was the troubleshooting that I found was most effective, in a post here [Tutorial][Experimental][Third-party Plugin available]Reducing OMV's disk writes, also to install it on USB flash

I also said that adding a watchdog script that does this procedure automatically was a good idea.

Danke dir für das Angebot, aber nach Boba's Anleitung geht es jetzt wieder. Das Neu Installieren lasse ich besser.
Jetzt kommt Bayern-Barcelona, nicht dass ich unbedingt Bayern Fan bin

Then reinstall the plugin and see if it still fails this way.

Thanks for your help. I think, I will wait until the issues are solved. Hope my SSD will survive it.

You and I are the only two people who ever experienced this problem. A second install went fine for me, too.

If you try again at least to see if it works fine at the second try, we can see if the problem is caused by something you have there or if it was just bad luck.
That means, you can help us solving the issues. That's what testing is for after all.

With all my harsh testing the worst that happened was what happened to you, but I did it manually to simulate a crash or an error, if your system can trigger errors consistently, that's something useful to know so the plugin can be fixed.

emsic · 6. Mai 2015

OK fully agree, but unfortunately a second installation was the same negative result.
What else I can test?

bobafetthotmail · 7. Mai 2015

I checked the source and did some modifications, can you answer the question in post below?
When there is a new version of the plugin, try again.

ryecoaaron · 7. Mai 2015

1.5 in repo.

bobafetthotmail · 7. Mai 2015

before installing can you post the results of

Code

free

and of

Code

du -hs /var/cache/apt/archives

The first gives us the amount of ram in your system
the second tells the size of a folder that I'm thinking is responsible.

If the second folder size is higher than half your ram, there are issues when installing the plugin. At the moment anyway.

I am a bit confused. After second trial yesterday failed, I did the remove, but no further enabling. Today when I saw your post, I did the commands, (but unfortunately I didn't look into the status of flashmemory, as I thougt it is still disabled). Then I did actualisation and want to enable it, but it already was enabled. Strange!
Does that mean it works now? Any futher to check?

Jetzt mitmachen!
