Free up rootfs space

2010-05-26T12:18:54Z

82.148.206.127:

{{Danger}}

Here's a simple howto for those suffering from lack of space in rootfs. The first suggestion is more of a temporary matter, for example to get enough space to install an update, but it's also the fastest and easiest. The suggestions are in order of potential threat to operating system. Least dangerous first and the most dangerous last. The rest are more permanent (and thus more useful), but they require [[root access]].

===Listing rootfs space on your device ===

Use this command to determine how much rootfs space is allocated, used, and available on your device.

df -h /

If you want to see all filesystems, use only "df -h".

===Disable Extras-testing, Extras-devel, and/or any other third party repositories===

Simply check the disabled box and save in the Application Manager's catalogues menu. Wait for app manger to update the lists. This only helps if you actually had these repositories enabled.

Disabling [[extras-testing]] and [[extras-devel]] will (currently) give you an extra 5 MB in rootfs

===Clear apt cache===

Run following command (has to be done as root)

apt-get clean

===Remove unused dependencies===

Run following command (has to be done as root)

apt-get autoremove

===List of big and rarely used files===

You can't just delete these files, this is just a list with ideas! You have to know what you are going to do with them (optify, backup+remove, etc.).

* /usr/lib/locale/locale-archive (28 MB)
* /usr/share/locale (10 MB, but you have to keep at least the languages you use)
* /usr/share/themes/alpha and /beta (they use 5-6 MB each, keep the one you use)
* /usr/share/fonts/arabic and /chinese (2,5 MB less for people who don't speak those two languages)

===Move apt cache outside of rootfs===

If you run into a problem while using apt-get you can temporarily (for one command only) have the apt cache outside rootfs to be able to download larger deb files.

Create a download folder on the eMMC to be used for the downloaded packages instead of the default apt archive folder.

mkdir -p /home/user/MyDocs/apt-archive-cache/archives/partial

Now execute apt-get with the -o option as root:

apt-get -o dir::cache=/home/user/MyDocs/apt-archive-cache <command>

for <code><command></code> you can enter the command you normally would use after apt-get.

Examples:

apt-get -o dir::cache=/home/user/MyDocs/apt-archive-cache dist-upgrade

apt-get -o dir::cache=/home/user/MyDocs/apt-archive-cache install <package>

===Optify Python===

If you have installed python or a python program before it was optified, you can optify it with this method. First [[Terminal#Opening_the_terminal|open a console]], then type the following commands as root:

apt-get install pymaemo-optify
apt-get clean

When the program is installed, type df -h in the xterm to see if it worked.
The output should now contain lines similar to this one:

/opt/pymaemo/usr/lib/python2.5
2064208 471712 1487640 24% /usr/lib/python2.5

===Remove non-optified packages===

If you have installed programs from extras-devel, third party repositories or rarely, but possible, extras-testing, the programs might not be properly optified. Removing these might help with rootfs space.

You can free space by uninstalling applications that you do not need. A problem is if you do not know how these applications are called. To find it out:

* [[Terminal#Opening_the_terminal|Open a console]]
* Start the application that you do not need
* In the Terminal/console, type:
ps -ef
You get a listing of all running processes, including the application you just started. To find out what package an application belongs to, enter
dpkg --search $(which ''processname'')

===Custom scripts===

====Script to free up space on rootfs====

This script will move some unnecessary files on rootfs to /home/opt/ to free up space on rootfs.

BEWARE: Icon Label Issue May Occur.
http://talk.maemo.org/showthread.php?p=654384#post654384

First, create a file, move-to-opt.sh for example, containing this script:

#!/bin/sh
# Nokia N900 Maemo 5 Script to free up space on rootfs
# ignoring errors when creating dirs that may already exist

# Moving ?? icons to /home/opt
mkdir -p /home/opt/usr/share/icons 2> /dev/null
cp -r /usr/share/icons/* /home/opt/usr/share/icons
rm -r /usr/share/icons
ln -s /home/opt/usr/share/icons /usr/share/icons

# Moving video on start-up to /home/opt
mkdir -p /home/opt/usr/share/hildon-welcome 2> /dev/null
cp -r /usr/share/hildon-welcome/* /home/opt/usr/share/hildon-welcome
rm -r /usr/share/hildon-welcome
ln -s /home/opt/usr/share/hildon-welcome /usr/share/hildon-welcome

# ??
mkdir -p /home/opt/usr/share/pixmaps 2> /dev/null
cp -r /usr/share/pixmaps/* /home/opt/usr/share/pixmaps
rm -r /usr/share/pixmaps
ln -s /home/opt/usr/share/pixmaps /usr/share/pixmaps

# Moving 'apt cache' to /home/opt - Valid until [https://bugs.maemo.org/show_bug.cgi?id=5746 Bug 5746] is fixed.
mkdir -p /home/opt/var/cache/apt 2> /dev/null
cp -r /var/cache/apt/* /home/opt/var/cache/apt
rm -r /var/cache/apt
ln -s /home/opt/var/cache/apt /var/cache/apt

# Moving locales [http://talk.maemo.org/showpost.php?p=568370&postcount=11 Source]
mv /usr/share/locale /opt
ln -s /opt/locale /usr/share/locale

Set the script's permission for executable:
chmod +x move-to-opt.sh
(note that this step will - without warning you in any way - not work on partitions which are only fat formatted, as maybe your micro sd card will initially be; in such a case, move the script somewhere else)

Run the script as root:
./move-to-opt.sh

====Script to safely free space on rootfs====

[[User:Tanner#Safely_free_some_space_on_rootfs|This script]] shows you how much space will be freed and automatically detects whether some directories have already been moved.

BEWARE: Icon Label Issue May Occur.
http://talk.maemo.org/showthread.php?p=654384#post654384

====Move some of the pre-installed applications into /opt====

Some applications like Nokia Maps and the microb-engine are placed in /usr/share taking up valuable root space, moving these files will not affect the apps. Moving Nokia Maps (has to be done as root) will save 8.7 Mb:

mv /usr/share/nokia-maps /home/opt/
ln -s /home/opt/nokia-maps /usr/share/nokia-maps
Moving the microb-engine (has to be done as root) will save 13.9 Mb:
mv /usr/share/microb-engine /home/opt
ln -s /home/opt/microb-engine /usr/share/microb-engine
Moving the "Getting started" app/tutorial (has to be done as root):
mv /usr/share/tutorial-applet /home/opt
ln -s /home/opt/tutorial-applet /usr/share/tutorial-applet

====Move themes====

{{ambox
| type = notice
| image=
| text = '''This may cause problems when changing themes, and reversing it is NOT possible unless the device is [[Updating the firmware|reflashed]]
}}

Add the following into the script above OR add into another script (with #!/bin/sh at the start)

# Moving themes to /home/opt
mkdir -p /home/opt/usr/share/themes 2> /dev/null
cp -r /usr/share/themes/* /home/opt/usr/share/themes
rm -r /usr/share/themes
ln -s /home/opt/usr/share/themes /usr/share/themes

[[Category:Power users]]
[[Category:N900]]
[[Category:Firmware update]]

====See rootfs usage per package====

This script [http://www.robinhill.me.uk/downloads/pkgsize.py] outputs a list of all packages in rootfs and their size therein. I can not vouch for its validity but it seemed decent enough.
"python pkgsize.py checkpkgs | sort -n" gives you a sorted result in bytes. Most of these files are supposed to be there but it might help you find some non optified ones.

SDLMAME is the [http://www.libsdl.org/ Simple Directmedia Layer] [[port]] of the [http://mamedev.org/ Multiple Arcade Machine Emulator]. MAME has the ambitious goal to make it possible to archive all arcade machines by creating working hardware emulators to host all the the game code, or ROMs, that these machines employ.

==Project Status==

The SDL variant of mainline, modern MAME is currently being [[port| ported]] to Maemo 5. For MAME for earlier Maemo versions, see [http://maemo.org/downloads/product/OS2008/xmame/ XMAME].At this point, MAME is only available in [[Extras-devel]], due to its incomplete state. For example, it might occasionally lock up your phone. There's no ETA on a completed version due to the huge scope of the project.

See [http://talk.maemo.org/showthread.php?t=42824 the Talk thread] for discussion of the progress. Also, you can help out a lot by designing keymaps and other settings for your favorite ROMs and sharing them. For example, portrait mode via rotation (in the settings, push the volume control) is available for games that orient that way, but special consideration of controls are required. Doing the footwork for this kind of thing will greatly help out because the maintainer has neither the time nor the inclination to do this for all ROMs.

Available tools are the settings in MAME and the settings in Accelemymote, which controls the accelerometer input as joystick events.

==ROM Directory==

ROMS go into any of the following folders:
* /home/user/MyDocs/roms (This is roms in N900 when mounted via USB mass storage)
* /home/user/roms
* /media/mmc1/roms (a roms directory on your microSD card)

==ROM Status==

Remember, for the sake of organization:
# Add games alphabetically and in the appropriate category.
# Make sure a game doesn't already exist in a different category.
## If a game is already in the list and in the same category as you would put it, make it '''bold''' by adding triple single quotes on either side of the name to indicate confirmation by a second tester.
## If the game is in a different category than you have it, move it to the Mixed Reviews list and indicate next to it the two conflicting experiences.
## If it's already in the Mixed Reviews list and you confirm one of the previous reviews, move it to that list.

Thanks for your help maintaining this list!
