could anyone please help me out?
i went to conky and it says i have 0 bites left from my /opt partition, but a few days ago i had about 300mbs.
i tried to uninstall some apps and i rebooted and it was still 0 bites free.
i tried to use filebox to delete a folder from /opt and i rebooted and its still 0 bites free.
and i wouldnt like to reflash the whole os, so hopefully you can just reflash /opt
thanks

Seems your /opt partition has problems.
If you reflash /opt you are also deleting the majority of those files in rootfs which are symlinked to /opt. So you better reflash both rootfs and opt and start over. Also, if you have a recent backup - or your n900 is still able to backup - at the time you restore, after reflashing, you get a chance to reinstall all the applications you had, or the select only some.

how can u reflash just opt and rootfs?
yeah it can still backup everything works besides wallpaper, music, videos, and app downloads and removals.

Please try to check in X-Terminal before trying something like reflashing.
What is the output of some unix commands to analyze the situation.
Check if /dev/mmcblk0p2 is mounted at /home and /opt is mounted at /home/opt.

Well everything you need is explained here:
http://wiki.maemo.org/Updating_the_tablet_firmware
It's in your own interest to read it well and don't start fiddling before you've understood it right.

Backup all your stuff from MyDocs (don't forget hidden directories) and make also a backup with the stock app. Double check you got everything.
Once you're safe that everything is secured, you flash the rootfs and then the emmc.
Your n900 comes out clean from this experience.
Then restore everything. When you restore from backup your application manager will offer you to re-download all your previous apps; you could exclude also some from the restore, especially bulky games, in order you're sure you don't clutter all your opt space again.

Good luck

thanks, i kinda knew most of that already
im just gonna backup the stuff it backs up with the backup app, and also my music, vids and pics

and also this is the stuff from terminal:

how do i check if its mounted and stuff?

I am sorry, should have been Please also check the diskusage for /home/user mount without options does tell you which device and which directory are mounted where.

Everything is mounted where it should be for /home and /opt, but the partition is full. Could be /home/user or /opt, so please check with the above command, which one is the culprit for wasting your valuable space.

i tried it and the list is so long that i cant copy and paste it all cause the top doesnt show up in terminal
im going to reflash the os like now, see if it helps
and also i think that maybe my phone cant recognize the /opt partition? because it says its 0B free and even if i delete stuff from it with filebox, its still 0B free...

more then likely your apt-get cache is full

sudo apt-get autoclean

or

sudo apt-get clean

will clean this out
