Mystery space taken up on MAIN (Not rootfs) Partition
 

Hi There,

I have a weird issue with my N900.. I did search and found a lot of threads however from what I can tell are about a different issue.

The other day I tried to upload a largeish (10gb) amount of music onto my N900 and to my understanding I had heaps of space left on the main partition (32gb). Ubuntu told me there was not enough space left on the device for this amount of data.. On closer inspection there is something weird happening. When I view the devices properties it says:

Contents: 2,563 items, totalling 5.6 GB

Free Space: 3.9 GB

23.1 GB used

3.9 GB free

This is the same when viewed on the device through settings..

To my understanding this is not a rootfs issue, my root fs is 66% full at one hundred and something mbs. I did have extra repositories setup but have since disabled them.

In the terminal I have gone through and check the folder size of all the main file-system folders, nothing showed anything over 1gb..

I am really confused. :eek:

Could anybody shine some light on this for me?

Thanks in advance!! :p

You could try something like:
To show you the disk usage of all directories under ./MyDocs/, sorted by size (smallest first)...

Maybe that will track down the missing space.

Hey Jedi

Thanks for that, I gave that a shot and all it showed up at the bottom of the list was existing music folders and maps.

I decided to give deleting all the existing music a shot to see what it would effect and BIG PROBLEM. the contents of the main partition have gone down to 470.7 mbs understandably but the free space has stayed at 3.9GB.... oh crap..

Any Suggestions?

Format eMMC...

No, it's all in the hidden folders, most likely.
try "ls -al" in xterm after cding to mydocs.

You can scroll up a bit and see the other files/dirs!

Alternatively you could add "|more" to the end to make it stop at the end of each page, but it might take quite a while to see all the files/dirs (press CTRL-C to stop)...
so instead you could add 'r' to the sort command to reverse it...
By the way, this will show you 'hidden' files (those starting with a '.')

Hi again,

Thanks for your help, much appreciated.

Okay so I've tried locating the issue using the suggested methods. unfortunately they point to small files.

What I did do though was take a copy of the stuff i needed such as images and contacts and then "clear device" through the settings top bar menu. This obviously restored most of the factory defaults and rebooted the device. When it was up and running again I checked the memory again and it has now jumped to 9.11GB! weird because this made a difference but not enough...

I have noticed something however, when i run "df" or "df -h" to make it easier to read i notice that there is the normal list other users post and then a series (8) of other individual directories or mounts that each total 2gb therefore totaling 16gb! i think the missing space is here each directory seems to have exactly 219.1mb in it. I am assuming they are all just mirrors of each other?

I cant post screenshots atm because my internet has gone over the limit haha but an example of one would be:

/dev/mmcb1k0p2
Size: 20g Used: 219.1m Available: 1.7g Mount: /home

and another:

/opt/pymaemo/usr/lib/python-support
Size: 20g Used: 219.1m Available: 1.7g Mount: /usr/lib/python-support

what do I do?

Could I delete these directories, or will they effect the system?

Sorry I'm a bit of a newbie. But the good thing is we've located the space.. well partitions taking up the space?

Thanks Again!

Those are all part of the OptFS, a second 2gb partition on your eMMC - NOT accessable via USB. It's where your programs go.
You should be using "du -h" instead of df -h - du gives you a directory listing, df gives you a listing of disks.

Hi Robbie,

Thanks for the tip. I gave it a shot woth "du -h" and looked through the list. nothing seemed big at all. the biggest files were the ovi maps ones at 400ish mb and there was only one or two.

Then I gave "du -ch" a shot to give it a total at the bottom as yeah all that total comes to is 595.8MB... not the 15 odd GBs im looking for..

Same when I do "du -ach" to show/include hidden files..

Very confusing, any suggestions?

Thanks again!

Use tar to archive it all with the "pcf" options(google for 'man tar' for full usage, copy it off, re-format, then extract your files again.
