 Posted: Fri Oct 01, 2004 6:01 am Post subject: reiser4 finally working for me... or not |
 |
|
reiser4 is no longer freezing my AMD64 system! I've built a kernel several times on reiser4, mounted and umounted several times, and now I'm using it for bittorrent download space. If anyone else has been having freezing trouble, try my patchset. It's based on vanilla 2.6.9-rc3 and includes:
Con's interactivty work, including staircase 8.2
elevator-switch-2004092100 (eg. "echo cfq > /sys/block/hda/queue/scheduler")
reiser4-related patches from 2.6.9-rc2-mm4
I didn't include reiser4-generic_acl-fix.patch because of compilation errors, and I omitted Con's VM work because it seems to behave strangely with a few memory hogs running.
EDIT: check this thread for newer versions of my patchset

| I wouldn't say I have mad C skillz. My most recent attempt crashed and burned (despite compiling correctly) because I tried using both evelator-switch and cfq2. If you want help with failed hunks or compile-time errors, remove the numbers eight and nine and email me at maci8ejej9@msoe.edu. |

Thanks for the patchset, I tried as many patchsets as I could but always had the lockup bug.
Unfortunately it doesn't look like I can mount reiser4 partitions with your patch, I see the following in dmesg
| Code: | bad: scheduling while atomic!
Call Trace:<ffffffff803578be>{schedule+94} <ffffffff80357dc9>{preempt_schedule+57}
<ffffffff802afcbd>{elv_register+109} <ffffffff8010b182>{init+226}
<ffffffff8010fdbf>{child_rip+8} <ffffffff8010b0a0>{init+0}
<ffffffff8010fdb7>{child_rip+0}
io scheduler noop registered
error in initcall at 0xffffffff802b6750: returned with preemption imbalance
io scheduler anticipatory registered
error in initcall at 0xffffffff802b9100: returned with preemption imbalance
io scheduler deadline registered
error in initcall at 0xffffffff802ba170: returned with preemption imbalance
io scheduler cfq registered
error in initcall at 0xffffffff802bb310: returned with preemption imbalance |
but the system does run, however I see this when I try to mount a reiser4 partition made with reiser4progs-1.0.2_pre1.
| Code: | deepthought lib # mount -t reiser4 /dev/hda5 /mnt/gentoo/
mount: wrong fs type, bad option, bad superblock on /dev/hda5,
or too many mounted file systems |
also the nvidia driver kept installing to /lib/modules/2.6.9-rc3-JM, and just copying the video folder and module over to the correct location didn't work, I had to symlink /lib/modules/2.6.9-rc3-JM to 2.6.9-rc3-JMn

| I didn't test with preempt enabled. My filesytems were made with 1.0.1 although I'm not sure it would make a difference. What's wrong with /lib/modules/2.6.9-rc3-JM? I set the extraversion to -rc3-JM. Normally I don't number my releases because I rarely make more than one. |

I'll give it a shot without pre-empt enabled, then when I get home from work tonight.
The thing is the modules path for the kernel seems to be /lib/modules/2.6.9-rc3-JMn, but when I emerge the nvidia driver it installs into /lib/modules/2.6.9-rc3-JM, so modprobe and modules.autoload won't find the nvidia module. JMn also appears as the kernel version from uname -a. Installed it with the standard make && make modules_install. No big deal since it's fixable by making a symlink before emerging nvidia-kernel.

Now I'm confused about the JMn problem. Do you mean a literal 'n' or an integer? Here's what I get:
| Code: | $ uname -a
Linux gentoo 2.6.9-rc3-JM #3 Thu Sep 30 20:00:33 CDT 2004 x86_64 12 GNU/Linux
$ cat /proc/version
Linux version 2.6.9-rc3-JM (root@gentoo) (gcc version 3.4.2 (Gentoo Linux 3.4.2-r2, ssp-3.4.1-1, pie-8.7.6.5)) #3 Thu Sep 30 20:00:33 CDT 2004
$ ls /lib/modules/
2.6.9-rc3-JM
$ bzgrep EXTRAVERSION 2.6.9-rc3-JM.patch.bz2
-EXTRAVERSION = -rc3
+EXTRAVERSION = -rc3-JM |
It looks 100% consistent to me.
EDIT: I now have ~12.5hrs of uptime with everything but /home on reiser4 |

here, see for yourself
| Code: | paulisdead@deepthought ~ $ uname -a
Linux deepthought 2.6.9-rc3-JMn #1 Fri Oct 1 22:15:04 PDT 2004 x86_64 AMD Athlon(tm) 64 Processor 3000+ AuthenticAMD GNU/Linux |
| Code: | paulisdead@deepthought ~ $ ls -d /lib/modules/2.6.9*
/lib/modules/2.6.9-rc3-JM /lib/modules/2.6.9-rc3-JMn |
still haven't had time to try without pre-empt on yet though.

My previous release was a little rushed and used old versions of Con's patches because his patch site was down when I made it. I've made -JM2 featuring
reiser4 from 2.6.9-rc3-mm1
Con's scheduler patches w/staircase 8.9 from 2.6.9-rc3-ck1
mapped watermark from -ck1 (giving it a second chance with positive results so far)
switchable elevators from -mm1
CFQv2 from -mm1
EDIT: I have a patch that adds only reiser4 if anyone's interested
WARNING: I had one reboot and one lockup with -JM2. I'm not sure if it was the kernel or hardware problems. Now I'm running +reiser4 because Con's patches don't make a noticable difference, so they're not worth the risk. |

Well, I still kept gettin errors mounting reiser4, and realized I needed large keys compiled into my kernel. So I could mount the stuff, but still hardlocked my system during big file copies. So I tried the patch for only reiser4, and that still hardlocked my system during large file copies. With just the reiser4 patch, preempt will not throw up those errors at bootup/in dmesg, but it's really unstable for me.

After running stable for 2 days on +reiser4, I thought I'd convert /home to reiser4. No, I'm not crazy, I have backups. While converting (not exactly converting so much as recreating) I was getting lockups and severe corruption; it wasn't pretty.
EDIT: in case any x86 users find this- I used reiser4 on x86 for about 6 months and never had any unexpected reiser4-related problems |

Thanks very much. I was looking for this. Now i have my kernel as i want, linux-2.6.9-rc3+reiser4+vesafb-tng 
Could you explain how do you do this reiser4 patch??
Thanks

How do I make the patch?
"wget -r -np" the latest -mm broken-out
apply all reiser4-related patches (follow the series file) except reiser4-generic_acl-fix.patch
expect one failed hunk and apply it manually
comment out the line that causes compilation to fail
These procedures may change with future versions. I know it's safe to leave out the acl fix because I grepped the -mm patchset and determined the changes it makes are mm-specific. The failed hunk is fairly obvious. The line I suggest commenting out got commented out in vanilla-based -ck and -cko sources. |
