[gentoo-user] reiserfsprogs

[James]

Hello,

Were are the docs for the utilities for sys-fs/reiserfsprogs ?

I cannot seem to locate any documentation of running fsck or such
utilities manually on a reiserfs partition. I want to read about
what those utilities are and how they work.

man reiserfsck, or # reiserfsck --help
try the same for reiserfstune and debugreiserfs.  If you want to create a 
reiserfs fs then look at mkreiserfs.

You can also use equery, which is in app-portage/gentoolkit. The
corresponding equery command would be

equery files sys-fs/reiserfsprogs

My problems in on a new installation. 
I'm not sure my resiserfs is auto checking
the /boot and the / partitions. 
I rebooted using a minimal CD mounted and set the fstab like so:

/dev/sda2        /boot   reiserfs        defaults               1 2
/dev/sda4        /       reiserfs        defaults               1 1

which should force an fsck on the reiserfs file system? 

The system hoses up when xdm is auto started (problems 
with the xorg.conf file.
I set xdm to auto start upon reboot (rc-update), and I'm not
sure what file I can edit ( or what else I can do from a minimalCD
boot) to stop this process set to autostart during the boot process?


Any ideas on how to recover are most welcome.

You maean after:

mount file systems
chroot /mnt/gentoo /bin/bash
env-update
<then> rc-update del xdm

This worked...

Now to fix the xorg.conf file.....

I cannot seem to use any of the tools 
listed here: http://www.gentoo.org/doc/en/list.xml
( Xorg -configure  xorgconfig etc)
to generate a working file. So I booted up the
livecd and copied that xorg.conf file to another
system later on for use. it works, but the screen
resolution is 1024x768. The system, an HP DV9000Z
laptop (GD545AV) is suppose to have a 17 screen with
1680x1050 resolution. Every time I try this resolution
the system hangs, hard and has to be power cycled to recover.
I also cannot find the hortz&&vert ranges. From the install I have:

        HorizSync    28.0 - 96.0
        VertRefresh  50.0 - 75.0

Another source of the problem could be all of those
fonts, in the xorg.conf file that I may not have installed.

Another potential source failure in getting xorg.conf
stable is dri and glx.
Different gentoo web pages tell me different things on using
these with the nvidia driver. They all still talk about
agp device drivers in the kernel.

Also, there use to be a guide one could follow to get xorg.conf 
working by testing it as a user logged in on console. every time
I try that, the entire system hoses up... It's been a while since
I had to use the minimal CD (2004.3) so I'm rusty and the docs
have changed/disappeared.  It should be easy, but, I'm having 
a helluva a time getting x/kde stable.

Any ideas or wikis I can follow?

Just as a side note: It is not very wise to choose reiserfs for /boot. We had 
a topic about it some time ago. On such a small partition the journal eats up 
a lot of space (32MB with default settings).

I'm not sure the math is 100% correct but it has to be close.  I agree,
you should not use reiserfs for /boot, unless it is going to be a big
one.  lol

I just looked into the man page of mkreiserfs: 

default blocksize: 4096 byte
default jounal size: 8193 blocks

4096 bytes/block * 8193 blocks / 1024^2 = 32.003906 MiB

It's not 100% but pretty darn close.  ;-)  Like you said earlier, you
shouldn't use reiserfs for small partitions like /boot.

Yeah ... definitely take note of that sucker , if you ever did dd

and possibly random files all over your file system who's names have

All joking aside, I've recovered reiserfs much more often than I've gotten 
anything useful out of a bad ext2/3 filesystem.

You have to know it's limitations, but I've had a growing reiserfs file 
system for over two years now that I've had to --rebuild-tree on at least 
3 times and never lost a drop of data.

My ext2/3 boot patition has died a similar number of times, and no amount 
of e2fsck gave me any data back (but luckily, /boot is fairly easy to 
rebuild).

I swear *by* reiser much more often than I swear *at* reiser, but I've done 
both.

Well OK, I got your instructions.

However, xdm is not turned on so the system boots straight to
a command line prompt. Previously I suspected the xorg.conf file
for startup during xdm launch-->latchup. After disabling X/kde/xdm, the 
system still has problems. Last night it was just sitting in
a quiescent state and it just latched up. Not good for a brand new
laptop. Today I booted it up and set the date on the command line.
Then I issued 'hwclock --systohc' and the system latched up 
tight, again. Power cycle and the minimal CD has the system running
a memtest86 for a while, to ensure it's not the ram.
If the ram proves up OK, then I'm going to follow your
previous instructions on repairing the reiserfs partitions.

What else could it be? This was a vista only laptop, so
if all else fails, I'll just blame Microsoft......
I ran fdisk but, it may need an old fashion dos format?
Suggestions on robust low_level formatting is I have to re-install
this machine?

I've got over a dozen systems with reiserfs on the /boot partition
and not a single problem in almost 4 years of running gentoo
and reiser on the boot partition. Losing 32M of space is a non
issue for me. Reiser gets a lot of bad press,
but, I like it very much and cannot wait until reiser4 is
a bit more of a commodity. 

I've had lots of problems with ext2 and ext3 (No thanks)......

I'll drop a line when the memory testing is conclusive.

thx,

James

For now the system is booting to a console prompt. I'm looking

Is the whole system handing, or just X? Do you have a networked computer
you can SSH in from, that would enable you to kill X. If all else fails,
and provided you have enabled CONFIG_MAGIC_SYSRQ in your kernel, hold
down Alt and SysReq/PrtScr and press S, U and B in turn to reboot
(reasonably) cleanly. Pausing a couple of seconds between each key is
probably a good idea.

E, I, S, U, B

so everything is killed, and nothing trying to write to disk, when unmounting 
them.

The entire system latches up tight, even the ssh remote shells and console.

I start X(kde) with startx. I followed the guides in
http://www.gentoo.org/doc/en/list.xml

Code Listing 2.4: Configuring your local session
$ echo "exec startkde" > ~/.xinitrc

X/kde runs fine, but when I exit it now, the system latches up, tight
all ssh sessions, the console, everything.

Interesting idea however this laptop does not have this key "SysReq/PrtScr".

Hmm, I do not think you understand, when I exit X/kde the entire system is
latched up tight. None of the keys work, nothing is echoed to the screen,
the system is latched up tight. All I can do is power cycle the system.
When I do that the screen fades and the mouse cursor is visible but slowly
fades to a solid white screen. The system hangs at the very moment I use
the logout button in kde, to exit the system.

Very strange and very repeatable.....

maybe emerge --emptytree world?

revdep-rebuild -p is fine.

Every keyboard has a SysRq button.  On most, it is shared with PrtScrn.  
However, I've also seen it shared with either an F key or ScrollLock or by 
itself.  Also, I've seen laptops where you had to hold the Fn key to get a 
key that acts like SysRq.

I guarantee you've got one, although I suppose it might not be labeled 
SysRq at all.

Please *try* the Alt+SysRq instructions if you haven't already.  Those are 
handled directly by the kernel at a fairly high priority.  I've had 
everything else be ignored, including C+A+Del, and had Alt+SysRq save my 
filesystems.  It is possible that you might not see anything happen after 
E, I, S, and U, especially if you were previously in X, since the kernel 
is trying to write to the text-mode console but things are happening 
unless your kernel has crashed.

All other keystrokes travel to user-space to be processed, so if your 
kernel is busy, they won't do anything.

As Boyd said, it may be hidden (in which case it is very well hidden on
this iBook, I haven't found it yet :( However, I've never seen an x86
system that doesn't have one somewhere.

Magic SysReq works at the kernel level, so it usually works even when the
system appears completely locked up.

Try Disabling anything fancy ( ie: composite support ), or try
disabling APIC. I had a glitch a while back where composite + apic =
system lockup, and later, something in QT4 tripped it up.

OK, sorry; between being very tired and aging eyes, I had to use 
a magnifying glass and found these 2 keys:
"home/prt sc" and "end/sys rq" the bottom ones look like function key 
markings...(tiny font)

So When X/kde freezes up everything I'm going to hold down these (3) keys:
ALT+FUNCKEY+SYSRQ" 
and then Sequentially press "E I S U B" with a 2 second delay between
keystokes
and the system will cleanly reboot?

This failed to work for me. After it hung, I tried the above and
many variations on this theme of keystroke to reboot. Nothing worked.
However, upon powercycle reboot, the system came back clean
with no fsck..... Maybe this keystroke sequence clean up everything, 
but failed to initiate a reboot?


Well, with no changes to the system or config files , 
this time X/kde failed to launch, or I guess
I should say the screen went black (dark) and just latched up the
system completely, all remote ssh session and the console LATCHED UP.

Repeatable now so KDE now launches to a dark (latched up) screen
now. When I boot to a console, the system is fine. When I launch
X/kde via startx it latches up immediately....


I have no idea how to figure out this problem. To me it has to be
the xorg.conf file?

Now X/kde will not start. Everything latches up as soon as I enter
'startx' at the console.

I have no ide how to  diable 'composite support'.
When the system was ordered it was specified 1680x1050 on the 
17 inch screen resolution. The few times (sporadically) I did
get X/kde to launch, it was is 1024x768 mode. I cold not build 
a working xorg.conf file, so I boot up the liveCD 2007.0 can
copied over the default xorg.conf that at least worked with the
liveCD. My suspicion is that xorg.conf file, particularly the
Hortz and Vert ranges:
 HorizSync    28.0 - 96.0
 VertRefresh  50.0 - 75.0

Or maybe it the long list of fonts from the xorg.conf file on the livecd2007.0
and I have not installed all of those fonts?

What I need a very simple xorg.conf for a HP Pavilion dv9000z.
Googling I found a couple but they did not work and hacking
xorg.conf files has always seem to be a moving target for me....


I eliminated acpid from the startup, it made no difference:
rc-update del acpid default

Right now I'm running 'emerge --emptytree world'
It's on 29/862  for lack of any better ideas.

From a terminal within X while you have booted the LiveCD run xvidtune (emerge 
it if you have to).  That will tell you what is the HorizSync and 
VertRefresh.  Assuming all is looking right with the LiveCD use these 
settings into your xorg.conf.  Another trick is to remove them completely 
(just comment them out) and xorg will try to guess them after it probes the 
hardware.  It may just work.  Final gotcha is the mouse.  I assume that if it 
works with the LiveCD the same settings should do it for you, otherwise you 
may want to try playing with mine below and see what gives:

==============================
Section "InputDevice"
        Identifier  "Mouse0"
        Driver      "synaptics"
        Option      "Protocol" "SynPS/2"
        Option      "InputFashion" "Mouse"
        Option      "Device" "/dev/input/mice"
        Option       "Name" "SynPS/2 Synaptics TouchPad"
        Option       "SHMConfig" "on"
        Option       "Vendor" "0002"
        Option      "ZAxisMapping"      "4 5"
        Option      "Emulate3Buttons"   "True"
        Option      "Buttons"   "3"
EndSection
==============================

HTH.

OK I'll give this a whirl, after 
emerge --emptytree world
completes. I'll try all of your suggestions and post to
a new thread on the result. The laptop (hopefully)
will be compiling all night.....

Right now I'm just a little fried and frustrated over
this machine.

I know how you feel . . . been there more than once.  The other thing you may 
want to check is the laptop manual for the monitor specifications.  The 
HorizSync & VertRefresh may be shown in there.

Good luck.

No, not  ACPI , APIC

in kernel menuconfig:

 Processor Types and Features ->
    Local APIC support on uniprocessors [ not checked ] ( CONFIG_X86_UP_APIC )

I have it off, and its left off, saves me headaches and needless hell.
