I always recompile my own kernels. Then I don't even have to worry about
modules or building initrds. The kernel is customized to my set of devices
though I do include all the devices for all my machines in each kernel so
I only need to manage one image which could be used on any machine.

If you need special device drivers just to access your hard drive, this can
be a problem. This is one reason why I always use an IDE disk, or a very
common SCSI controller, for the system, and leave more complex stuff like a
huge RAID array to purely the database by itself (the only cases where I
would have such a thing).

rpmbuild error during kernel recompile

Try typing the command 'uname -m' without the quotes first, then
substitute the results into the command, example below;

$ uname -m
i686

$ sudo rpmbuild -bp --target=i686 kernel-2.6.spec

Step 7 from you link should be;

sudo make ;(combines both makes into one)
sudo make modules_install
sudo make install
sudo make rpm ;(creates a binary rpm of your work)

You should also review;

Minimum hardware spec for various Linux installations?

Posted: 16 Apr 2005 10:42 AM PDT


Cuzman (com) writes: 

All distributions pull from the same pool of the kernel, utilities
and applications. They differ in philosopy and what is tossed
into the distribution. They are more alike than different.

One difference is the installation process, which may appear
to be the biggest step for the newcomer but which is a relatively
small thing compared to actually using the operating system.

And the actually installer that a distribution uses is the defining
point on what hardware it will work with. Some installers are very
bloated, so you need a massive system to do the installation. Others
use a simpler installer, and they demand much less resource to install.

But the requirements for the installer have nothing to do with the
use of that distribution. Given the same version of the actual kernel
or the applications, either they will run fine on a given speed CPU and
given ram, or not. The specific distribution has nothing to do with this.

Hence, you will see "requirements" for a distribution, and then see fine
print telling you it will actually run in a much lesser system. But you
can't install unless you have the bloated system.

In some cases, they include a non-GUI installer so you don't need a large
system to install.

Installation aside, the hardware will affect how the applications run.
But since the distributions try to compete with each other without having
much different about them, few will go to the radical step of removing
applications. So you will have a fine selection of what to use; if
this GUI is too slow, then you can switch to one of the other GUIs
that come with the distribution. If the CPU is too slow (and I'd
not call that CPU slow), then you can always switch to text based
applications rather than GUI based. But switching to another
distribution will not fix this problem, since they will be using
the same applications.

You didn't shut down cleanly; if you were using ext2, fsck would run and

Where did dhcp go?

Posted: 13 Apr 2005 10:30 PM PDT

Michael Hennebry <cs.ndsu.nodak.edu> wrote: 

Then there is no sshd server running on the target, or it is firewalled
from you.

I would imagine the latter. So open its firewall for you (i.e. your IP
address). Heck, open it anyway. Port 22 is meant to be accessed. That's
what it is for. DOn't leave any open passwords, and that's that.

 

Then you mean "I was not then capable", not "I cannot".

 

Then open your firewall or run sshd there. End. You can ping it fine,
so there is nothing wrong with your network setup, which dhcp is meant
to configure, and evidently has configured, satisfactorily.

smartctl's "Non-medium error count" (SCSI drives)

Posted: 13 Apr 2005 06:05 PM PDT

On Wed, 13 Apr 2005 18:04:09 -0700, prg wrote: 

Now that's interesting. I tried copying one of the affected files from the
drive, which died with an I/O error - suggesting that the block couldn't
be read at all. Yet smartctl output is only showing non-medium events and
nothing under read/write events...

That suggests cabling to me, but it's funny how the other drive on the bus
has been fine (I'm well used to SCSI so I've seen some pretty odd things
happen though!). Maybe there's a problem at the drive connector to that
specific drive - I'll have a look.

Oddly enough, an hour after I posted, the problem had gone away again,
which is rather spooky. Nothing on the system was scheduled to kick in
around the time of the problems, nor were any big inductive loads nearby
active (!) or anything like that. I hate random glitches :-(
 

Will do - thanks. I'll probably copy all the data off the drive, wipe it
and do a destructive test/rebuild of the filesystem just to see if
that throws up any bad blocks. I'll double-check cabling first though
:-)

mdadm -A (1.7.0) segfaults; md raid device not started on boot

Posted: 13 Apr 2005 02:00 PM PDT

Walter Mautner wrote: 


I didn't post after "Mounted root" because there's no further mention of
md. The entire dmesg output is below, for completeness.

How does the kernel know to load the raid module when I invoke mdadm,
but isn't able to do this in the boot process? I'd like to be able to
get this working *without* having to recompile the kernel, if it's
possible. The root filesystem is ext3 on a normal hd device, and it's
already mounted by the time we want to start up the raid device, so in
my mind we should be able to load the raid1 module at this stage.

Would it be easier to add raid1 to initrd, or to just recompile the kernel?

Thanks,
Alistair.


[dmesg output, after boot has stopped when filesystem on md device can't
be mounted. This is *all* of the output.]

As long as the second machine is configured to forward to the
exchange machine, they can have the same priority and you'd get some
load balancing.

Better yet, pull the exchange box behind your firewall and let one or
more postfix (for example) machines front-end it; that way you can drop
most of your spam & garbage before it gets to exchange, plus you're not
hanging an MS 'hack me please' Exchange target directly out there. I
use a setup like this, with postfix + amavisd, and it cuts down a *LOT*
of traffic from ever getting to the exchange box.

The real crunch is going to come in if you really expect the Linux
host to be able to take over in case the exchange machine melts down. I
am not personally familiar with any open source exchange replacement
that can do this transparently (which is not to say there isn't one.) I
suppose the long hard ugly way would be to duplicate all your user
accounts on a Linux host with IMAP or POP or some such configured, and
then have all the users reconfigure their mail clients in case of
emergency. *YUK!*

Assuming you use Active Directory, a slightly less painful
alternative might be to set up a machine with winbind. You would still
have the mail client reconfig to contend with, but at least you wouldn't
have to futz with accounts and passwords...

If that all seems too complicated, there's another wonderful disaster
recovery technology you might want to look into, called 'backup
tapes'... *grin, wink!* :-)
