[Important] Rootfs deleting/relocating
 

Hey guys, (:
LOL WHAT A LAME INTRO, ANYWAYS!

So yeah, My rootfs was at 80% and I got sick of looking at it, so I changed it to 65% and it's 84mb now?
Anyways, theres a tweak you should all watch out for.

This command is very dangerous.
Here are the out-comes and in-detail explanation of what this command does.

In-Detail Explanation Of Original Command
mv /usr/share/microb-engine /home/opt -- This part moves "microb-engine from the usr/share/ directory, to home/opt (Non rootfs 256MB storage)

ln -s /home/opt/microb-engine /usr/share/microb-engine -- This part sets the instruction to find the microb-engine (Otherwise known as Web Browser) to home/opt/microb-engine from /usr/share/microb-engine (Yes yes, the rootfs 256MB Partition)

Effects
1. Web Browsing will NOT work.
2. The important and probably most scariest problem of all. 100% CPU Usage on IDLE

Yeah, 100% CPU at 600MhZ non-stop without even touching your machine. Thank god it was on a low priority and reversed the effects.
Here's how, just incase you bump into such a bug.

In-Detail Explanation of Command

mv /home/opt/microb-engine /usr/share -- Moves home/opt/microb-engine folder to /usr/share (Original 256MB Partition rootfs)
ln -s /usr/share/microb-engine /home/opt/microb-engine -- Tells OS to find the program at usr/share/microb-engine from /home/opt/microb-engine

Anyways, hope you guys never bump into this bug, if you do though, hopefully this will prevent you from reflashing your machine.
Happy N900'ing. (:

How did you run into this exactly? Did you decide make this change manually?

Re: [Important] Rootfs deleting/relocating
 

Web browsing works here (after moving it), and the CPU goes down to 250MHz when idle.

Re: [Important] Rootfs deleting/relocating
 

I don't know what . But im bumping into many problems. Now when i web browse, i cannot change pages. Fman. Stupid tweaks cause Devel programs messed up my whole rootfs.
What do you mean change manually?

I did a few edits to make my rootfs smaller.

I've also done the Python thingy.
Took out some languages. Ahh, now my machines a bust. Is there anyway to undo, or is it reflash?

That and the home/opt edit.
I really think reflashing is right around the corner for me. Goddang it.

Re: [Important] Rootfs deleting/relocating
 

OMG, someone please reply.

Re: [Important] Rootfs deleting/relocating
 

type ls -lah in xterm check the ownership and permissions of the file. Paste output here if you don't know how to read it.

Re: [Important] Rootfs deleting/relocating
 

I did the same thing :(

mv /usr/share/microb-engine /home/opt
ln -s /home/opt/microb-engine /usr/share/microb-engine , now my cpu is at %100 all the time and my memory is at 174mb ! ,

It seems all the roofts everything is messed up , after opening like 5-6 applications , it is at 100 percent (after using the command
mv /home/opt/microb-engine /usr/share
ln -s /usr/share/microb-engine /home/opt/microb-engine , my cpu usage become better but still I think it is not same as before )


someone please help !

Re: [Important] Rootfs deleting/relocating
 

ive also moved the microb engine and all the other things mentioned in the wiki except for running the script as i didnt feel safe doing it.
Anyway everything is running fine for me, (touch wood)
wouldn't that script be the more likely culprit, especialy if you've moved microb back.

Re: [Important] Rootfs deleting/relocating
 

so what exactly I have to do matts76 ?

how did you fix urs ?

Re: [Important] Rootfs deleting/relocating
 

sorry you missunderstand, mine was never broken, what i was saying was could the script on the wik be behind the problems ur having, if so i believe there is also a reversal script on the wiki,
ive done everything else on the wiki without problems,

Re: [Important] Rootfs deleting/relocating
 

Yeah , I used the script on the wiki and that is why I have problems , I could not find the reversal script on wiki though :(

Re: [Important] Rootfs deleting/relocating
 

what happened to me is that i did the apt-get pymaemo optify and then the same action told me to apply the apt-get autoremove, and now my
N-900 is not possible to turn on it only gives me the dots for 5 o 7 seconds and after that shut down completely; no matter how many times i try to turn it on its not possible anybody can give a clue what to do?

Re: [Important] Rootfs deleting/relocating
 

That is what is comonly refered to as bricked:eek:.
Im afraid a reflash is your only option there is a wiki on how to and multiple threads on the subject, i had to reflash mine a while back its really not as bad as it sounds:)

Re: [Important] Rootfs deleting/relocating
 

well i think there is no other solution for that anyway this is going to to be the 10000000000000000000000 times i reflash the n900 well at least i am getting trainned on this device jejejejejejeje be calm peace be calm:eek: ths for ur response at least i know what to do now.

Re: [Important] Rootfs deleting/relocating
 

im sorry but i dont know how to help, other than a reflash would sort it out or if you wait for pr1.2 i think that will put everything back where it should be.
thats exactly why i havent used any of these scripts as i dont understand them enough to fix any problems,
but if ur device is working but just not perfect i would just wait for the new firmware, although learning how to reflash your n900 is something i would recomend everyone to do

Re: [Important] Rootfs deleting/relocating
 

yeah u are right matts, stay away from what u don't know specially if u have the risk of mess ur device; now i know. and u know what is funny? i was getting ready to install the new software updating, after what i was doing i was planning to do it, and now look at me where i ended. but thks anyways u have been very helpfull.

Re: [Important] Rootfs deleting/relocating
 

oh well , I guess its time for flashing , is there any easy to follow guide for newbies other than the wiki ones ?

I couldn't go through it lol

Re: [Important] Rootfs deleting/relocating
 

Oh SR90.
If you've ever done
Than download THIS

and do this command.

This should almost fix all your problems. The OS may be a bit messed up, just a bit, but it'll be alot better than before.

Goodlucks.

Re: [Important] Rootfs deleting/relocating
 

can we keep sensible warnings next to any commands like these please?

Anyone trying commands like these really need to understand how to fix / reflash if they hit problems, and just advertising commands may influence others to try - especially before reading the whole thread.

Re: [Important] Rootfs deleting/relocating
 

my thoughts exactly.....some people arent meat to be hacking. just accept it....(oh and i am one of those people) i know my limits and have learned the whole flashing routine just in case. but i dont push my luck.

Re: [Important] Rootfs deleting/relocating
 

I want to loose my roofts ,either!!!!!!!!!!!!!!!!!!!!!!!

But what the problem I face is that: I followed the tips suggested in the aptitude and indtall many unknown packages just because it suggested when I install the pyside or sth (I just forget huh)

So mine is PR1.3 and install the CSSU ,would anyone give some help to me????

Re: [Important] Rootfs deleting/relocating
 

Hi pursueky,
please do not get me wrong.
Your phone's problem may get better recognition, if you would start your own thread with a good, long description of the issues you are facing.

Re: [Important] Rootfs deleting/relocating
 

But I think the answer won't be such.
I have already found two
sth in "perl" and another in "python "(however,none of each reach my points)


Typing here somewhat means I can't handle it very effectively. And I just want to get some more experience from this useful thread also some selfless help.

Re: [Important] Rootfs deleting/relocating
 

though tips here may gonna help a little
I would be thankful all the same
