Help- View Ext4 Partitions in Ex3 Kubuntu

[shah81]

Hi
I had many problems with Jaunty (using ext4) and my laptop freezing, so just reinstalled Kubuntu 8.10
Problem is I have a few partitions now which are ext4, but since I installed Intrepid, that's ext3.
Dolphin doesn't let me open the ext4 partitions.

Can someone please tell me how to view and mount these partitions? Or downgrade them all to ext3 if that's necessary?

Thanks!

Re: Help- View Ext4 Partitions in Ex3 Kubuntu

Only Linux kernels 2.6.28 and later support ext4. So 8.10 isn't going to be able to see ext4 partitions. The only way you can work with them would be to boot a 9.04 Live CD. There's no "downgrade" of a filesystem -- you can copy your data elsewhere, and then re-format it with GParted or e2fsprogs if you want.

I installed 9.04 on an ext4 filesystem, and have no problems with it.

What were your problems with Jaunty? It sounds like maybe Intel/video issues?

Re: Help- View Ext4 Partitions in Ex3 Kubuntu

Thanks for replying. That sucks lol.
Can I upgrade to the latest 2.6.30 kernel whilst using Intrepid?

What happened in Jaunty is that whenever wireless was on it would hang. Tried different things - putting acpi off, powerdevil off, upgrading to kernel 2.6.30 but nothing worked. I have an nvidia graphics card btw, not intel.

I had a scare now using Intrepid too because the system froze, but since then its been okay for the past 2-3 hours. Hope it lasts!

I've written about that problem on here too but unfortunately didn't get a solution.

Thanks again.

Re: Help- View Ext4 Partitions in Ex3 Kubuntu

it's not too hard to compile your own kernel if you want. There are plenty of tutorials on the net, specific to the 'buntu's. You could compile your own kernel of 2.6.28 or whatever you want. if it fails, no biggie, you will still be able to load the old one.

Thanks muzicman
But what would the point / benefit be of me installing my own kernel?

I have downloaded the 2.6.30rc2 files, but will ext4 and Intrepid work if I install that kernel? I had tried it, but there was an error so didn't continue. I read somewhere that ext4 only works with Jaunty etc, but I assume that's because of the later kernel version?

Re: Help- View Ext4 Partitions in Ex3 Kubuntu

IMHO....

I would use the Kubuntu 9.04 live cd and move information as you needed. It may be a bunch of hassle. But if preservation is what your after, this may be the easiest, although it's a bit tedious.

Potentially you could compile a 2.6.29 or 2.6.30 kernel with the wireless driver that your wireless chip needs, thereby putting an end to that problem. Although I find it surprising that you can't find a boot option plus driver module that will let it work correctly.

I have downloaded the 2.6.30rc2 files, but will ext4 and Intrepid work if I install that kernel? I had tried it, but there was an error so didn't continue.

No guarantees -- you're on your own. But there's no obvious reason that the rest of the 8.10 Kubuntu suite wouldn't run with a 2.6.30 kernel.

I read somewhere that ext4 only works with Jaunty etc, but I assume that's because of the later kernel version?

Yes, I think so. The limitation is not "Jaunty", it is "2.6.28 or later".


If a 9.04 Live CD seems to work correctly with your wireless (install wicd and try it), then maybe the simplest thing to do is (a) backup data and (b) install 9.04 and wicd.

Re: Help- View Ext4 Partitions in Ex3 Kubuntu

Thank you all for your replies.
I don't know what's wrong, but my laptop froze on Intrepid too!!!
Sometimes within a few minutes, sometimes longer.

I've just installed Linux Mint since I thought I'd try something new. I know that runs on Ubuntu anyway, but lets see.

In case it freezes on this too, how can I check the reason? Thanks.

Re: Help- View Ext4 Partitions in Ex3 Kubuntu

Oh gawd!
It froze again just now. I bet its going to keep happening. Is there anything I can do?!

I've tried wicd also in the previous distros, nothing seems to work!

Re: Help- View Ext4 Partitions in Ex3 Kubuntu

if ur using a laptop and all ur linuxes freezes it might not be software problem but a hardware problem

pcs usualy frezze when ur mem or some other part of it heats up to much

did u mess with ur bios? overcloking? or did u change something in ur hardware?
what laptop do u have?

nvidia and laptops have some strong temperature issues in hot countries

does it frezzes at any time or when u execute somenthing in particular?

plese answere the questions as much as u can
dont worry well get there

Re: Help- View Ext4 Partitions in Ex3 Kubuntu

Hi, thanks for replying.
Yes, my laptop does get really hot even though there is a usb cooling fan under it.
But when I use a wired connection, so far its never frozen.
On wireless, it can freeze anytime, within 1-2 minutes of using it or after 10-15. Now its more regular. I haven't over clocked or anything or changed hardware etc.
I upgraded to kernel 2.6.30rc2 also but same problem!

Let me know what else you need?


Thanks!

Re: Help- View Ext4 Partitions in Ex3 Kubuntu

that dosent look bad............exept the the average line.

load average: 0.23, 0.33, 0.34

was your wirless runing?

I use a ndiswrapper loaded driver so ntos_wq uses up the box some espeshaley when dl'ing

845 root 15 -5 0 0 0 S 4.0 0.0 23:55.36 ntos_wq

just what ar the specks on that lappy............I have a old one 700MHz CPU 128RAM ATI mobilaty graficks ........and a lot of internet and vidio WILL over heat it even runig under xfce.

but that takes an hower or so of heavy use.

PS: sorey I forgot to mention it mite be esear to copey the top output after hiting Q to stop it.

Re: Help- View Ext4 Partitions in Ex3 Kubuntu

hi, thanks for replying.
honestly, i can't recall if wireless was on or not lol. sorry!below is the output with wireless on (just for a minute to do the task).
I'm not sure what the average line means, should I do something? Laptop is a Packard Bell, centrino 2ghz, 2gb ram,80gb hdd, 256 dedicated graphics card. anything more u want to know? should i paste the output of some other command?
My laptop used to overheat on windows - but it would just shutdown as a safety feature according to what I read. this just freezes. and again, only when I'm on wireless. And this is recently, in the past 2-3 weeks only. Can hardware deteriorate so easily!

Another thing that I don't know if its related or not - before when using Kubuntu (9.04) and just now again on Linux Mint, the x server just restarts itself. Don't know why; it happens once in a while after a few hours. Just stops, and restarts itself within seconds.

Anyhow - here's the results of Top, with wireless on. If I need to do it for longer let me know? This was on just for 20-30 seconds...
