ext4: pnds won't start

[A2000]

Inspired by the thread about advantages and disadvanteges of filesystems I decided to make the biggest partition on my new 32GB SD card ext4.


Using GParted.pnd I created following partition scheme: unallocated 4 MiB; FAT32 2 GiB; ext4 27,19 GiB. Then I made the ext4-partition writeable with chmod ugo+rwX and copied over the contents of my old SD card without problems.


Now Firefox13 won't start any longer. It complains that there is yet another instance running (which isn't).


Even weirder: Super Geometry Dust will start once after a reboot. But if I quit and try to run it again it won't start. There is a message in the output on temp that it "couldn't open dpads".


What's wrong with my installation?


NB If I insert my old SD card (only one FAT32 partition) I can use both programs as normal. Tried reinstalling Firefox on the new card with no success.

I would try using the SD Intaller application from the Repo to prepare your card, and then copy your home directory over.

Thank you for your advice, but I'm not sure if this is the right direction to go. Maybe I was a bit unclear in my first posting.


I haven't installed the system on my SD card. I just boot from nand. I only changed the filesystem for the partition which stores my personal data (=directory pandora with desktop, menu and so on). Do you think SD Installer will be the right tool for me nonetheless?

 

[mindlord]

Oh, I see. Hmm... It's probably a permissions issue then. Try:

sudo chown -R [username]:[username] /media/[SD Card Partition Label]/

Replace the stuff in braces with the appropriate values.

I also suspect that permissions are set wrong as thats the only difference between ext4 and FAT32 in the first place.

Unfortunatly your advice didn't changed the problem, everything is as before. I even tried

sudo chown -R [username]: /media/[SD Card Partition Label]/

 

[mindlord]

You can try using "sudo thunar" and using the gui to set the permissions instead. I'm pretty sure that my line should've worked though. It's possible that ownership of the card itself needs to be changed.

Do you have any pnd logs in /tmp ?

I think the command itself was executed. Will try the gui later, as I had to drive home now.

 

[A2000]

Do you have any pnd logs in /tmp ?

Yes, I have logs for both. All I can see is said line "couldn't load dpads" in Super Geometry Dust's log. And only "Success" messages until "umount the PND" in Firefox's log. Will try to attach logs later.

 

[Linux-SWAT]

Did you actually tried to manually write something on the filesystem ?

Hmm, log for Super Geometry Dust has changed as I tried to start it several times after each shell command.

 

[A2000]

Did you actually tried to manually write something on the filesystem ?

I habe copied the content of my old SD card to the ext4 partition on the new one. Does this count as "writing manually"?


Just wrote a test document with AbiWord in the root directory on said partition, tried to read it with mousepad: no problem.

 

[A2000]

You can try using "sudo thunar" and using the gui to set the permissions instead. I'm pretty sure that my line should've worked though. It's possible that ownership of the card itself needs to be changed.

OK, started thunar with tunar and checked rootdirectory, pandora and appdata. All permissions are set to the correct values: read and write allowed by me, my group and everyone else.

If you did this as user, it should be fine, but also try in appdata.

 

[A2000]

Okay, created a new empty file as user with thunar in pandora/appdata/hdonk_firefox_001. No problem.


I'm now going to delete hdonk_firefox_001 and see whats happening then if I start firefox again.

 

[A2000]

That worked for Firefox! Should have done that before but I hadn't found the directory as I was looking for one named "firefox" not "hdonk...".


I can see that some permissions are set differently. For example ".wh..wh.plnk" is owned by root and only drwx instead of owned by me and drwxrwxrwx.


Will try to delete appdata of Super Geometry Dust. Oh my highscores .

 

[slaeshjag]

Highscores can probably be saved, they're just a textfile

 

[A2000]

Yeah, I've seen this. Strange, editable highscores...


Got no success from deleting appdata though. The message "Couldn't open dpads" remains in the log.


What is this "dpads"?

You could try to ask wermy directly in his releasethread.

Ah, didn't know that it was still active. ...Done.


Thanks for your hint.
