Reiser4 + laptop_mode?

Reiser4 + laptop_mode?

[Yulia Shabunio]

Hi!

I want to use reiserfs 4 on my laptop. But i doubt if i can combine one 
with laptop_mode.

Can reiserfs 4 and laptop_mode work together?

Thanx!

I've been using Reiser4 on my laptop for a while and all I can say is,  
well, that's the only filesystem that makes a crap 5200rpm drive  
responsive and usable. That's really great !

However, there are a few problems...

Sometimes, when I power down the laptop, the usual power down sequence :
- Unmounting Filesystems
- Remounting FS read-only
- Power Down

Stops at "Unmounting Filesystems" and stays there forever ; and I have to  
shutdown the thing manually, pressing for 10 seconds on the power button.  
Annoying.

Also, a few days ago, my laptop battery died and the thing had a hard  
shutdown. The harddisk had spinned down a moment ago (I remember hearing  
it doing its clunk-bzzzzz....). Before you mention, no, I don't use the  
thingie to automatically shutdown the laptop just before the battery dies,  
because ACPI sucks on mine, and 50% of the time it says 0% charge left  
when, in reality, it's at 99%, and the damn thing would shut itself down  
every 5 minutes.

So, after that, my Reiser4 FS died and I had to run a fsck with  
rebuild-tree from a kanotix boot cdrom.

What happened ?

Re: Reiser4 + laptop -> ouch

[PFC]

I have this kernel :

linux-2.6.11-cko1-swsusp2

I chose this because it has reiser4 included, and software suspend 2...  
turns out software suspend does not work on this laptop, so I don't use  
it...

How can I get the filesystem version ? I grepped the reiser4 kernel  
sources for "version" but nothiing relevant came out.

Thanks for your help.

Try a 2.6.12 or 2.6.13 kernel, without swsusp2 patches included (since
they don't work anyways, you shouldn't run a kernel with them in case
they do funky things).  Maybe a recent -mm kernel?

Suspend2 has been improved substantially, and works for most people,
if they put a few minutes of their time into setting it up properly.
It has been cleaned up substantially and wont do 'funky things' like
you suggest.

An -mm kernel is more likely to do funky things, then a well patched
suspend2 + reiser4. Try archck, http://iphitus.loudas.com/archck.php

I'm sure that is quite true, but that all said, Resier4 is actually in
the -mm patches, IIRC.  *shrugs*  Either way, it's up to him whether
or not he wishes to have another go at reiser4+suspend2.

I can confirm that this combination works VERY reliably for me. I also
have the fbsplash patches, which gives that extra polished feel.

I have been using reiser4 since it's release and have had no serious
problems with the fs that I didn't cause myself. The issues encountered
were when I filled up the root partition, things were not handled
particularly gracefully (system started to crawl, very difficult to free
up some space). 
The only other thing was when I accidentally did a fsck.reiser4
--build-sb --build-fs /dev/hda instead of /dev/hda1. After about 30
minutes of running, I realised. After manually rebuilding the partition
table and re-running fsck.reiser4 /dev/hda1, the filesystem mostly
survived, with only a few corrupt files.

Well done reiser4!

It does 'funky things'.
On my laptop with reiser4 + LVM it was too many attempts to configure
swsusp2 after which I gave up. swsusp just works fine.
The last time I tried swsusp2,I lost data from my /home partition.
