 Posted: Thu Apr 29, 2004 1:53 pm Post subject: Possible that your reiser4 kernel MIGHT have a bug - fix |
 |
|
EDIT: THERE WAS NOT A ERROR! IT WAS ONLY A ERROR IF YOU HAD DEBUGGING ENABLED
URGENT! we think we made a error when doing the reiser4 diff to 2.6.5!!!!!
I STRONGLY recommend upgrading your old speedy/redeeman -sources to this kernel i made:
http://kaspersandberg.com/~redeeman/Redeeman-Sources/2.6.5-Redeeman45
it inclues:
reiser4, v30d (yeah, new one), CFQ, hrtimers, config-nr-tty-timers
we are sorry the inconvenience it has caused.
actually, i dont think there is anything wrong, BUT, i am not sure yet, and probably will first be later today, so i think that i will tell.
and to everyone that might have experienced instability with reiser4, this could very well be why, (in case there is anything wrong).
i will let you know when i know more.

I get this error when trying to patch the kernel
can't find file to patch at input line 2455
Perhaps you used the wrong -p or --strip option?
The text leading up to this was:

But made a typo 
Tell me about v30d: where can I find the patch itself? And how do you fix the conflicts it has with other patches?
I tried speedy4 yesterday, but couldn't compile. So today I played around and made my own patch set. The only thing is I couldn't get v30b in cleanly, tried to fix it by hand, but it failed on compile. So I left it out of my kernel for the moment, which works fine for now. But I'd like to get Nick's Scheduler in... |

i cant compile a vanilla 2.6.5 patched with the latest reiser4, with gcc 3.4 or 3.3.2:
| Code: | fs/reiser4/as_ops.c: In function `move_inode_out_from_sync_inodes_loop':
fs/reiser4/as_ops.c:570: error: structure has no member named `dirtied_when'
make[2]: *** [fs/reiser4/as_ops.c] Error 1
make[1]: *** [fs/reiser4] Error 2
make: *** [fs] Error 2 |
afaicr the kernel patched ok, why cant it compile?

That's because there's a few bugs still in the code. You need to apply these fixes:

Lets say I want a file system for movies, mp3s, and all of my ooffice files, would reiser4 be stable enough for that. It has take me a long time to get all of my movies, mp3s and docs so it would not be good if they were lost. I would like to try rieser4, it sounds really good, I just don't want to lose everything.

okay, I'm going to use it and probably not back up unless there is an easy way to back up 34+gig of files.

Getting a DVD burner would be a good idea, but a dvd burner and dvds would cost me about $120 or so, and I would be left with about $24 to my name. I can live with the chance of everything being deleted. And I've already moved most off my files over so it doese't really matter much anyway.

I'm just performing an installation with reiser4 on my lapotp. hope it works. I allways had problems with the other file-systems when i had a crash. reiser3 seemed to be the best so far. with xfs i couldn't access my mails anymore after a crash, and with jfs i LOST my file i was working on at the moment of the crash (this was really bad). I have so many crashes at the moment, since the actuall kernel has a problem with firewire.
Now, this should be better with reiser4, if i understand the atomic-system right. i'm sure i lost the other file, since i was just writing on it (or accesing?) and the write command wasn't finished. So it may seem wierd, but i'm actually changing to reiser because of stability We will see. Hope it works.
Edit: Thanks Redeeman for your great work. 
Edit: oh man, i actually wanted this message to appear in the Reiser4 enabled gentoo livecd - release notes thread, but i had too many windows opend and i posted it here. well it's not completly off topic
