Sound - /dev/dsp

That was what artsd (I think it is defunct now) and pulseaudio are all
about. -- /dev/dsp, the oss port, or alsa both do not allow mixing of
sounds, thus when one program opens the port, others are kept out.
Firefox does not lock /dev/dsp "as long as the browser is up" but while
it is playing sound-- and you said you were playing sound.

Does anyone have pam_mount working well for RHEL 5?

What to expect with out-of-sync RAID devices?

I am using software RAID on two USB drives. I know that
re-syncing can take ages; but I am prepared for this. Yet I must
prevent that one drive gets written to and then the other one
gets also written to, so that concurrent versions emerge and none
of the two drives is the "old" one which can be safely
overwritten with a mirror of the "current" one.

In other words: At each point in time, both drives must have the
same content, or one of them must have only obsolete content.

Lets call the drives A and B. Assume that I remove drive B by
pulling the USB plug. Then I do "touch current-drive" to mark
the remaining drive. Then I shutdown the system, re-connect drive
B and boot again. In all my experiments, this lead to a degraded
array being assembled with partitions from drive A. So far this
is what I needed. I can then re-add the partitions from drive B
with something like "mdadm /dev/mdX -a /dev/sdXX".

However, I also did the following experiment: after pulling the
plug on B, writing the file "current-drive" to A and finally
shutting down, I booted with only B connected. The system got up
and did its fsck (as expected, since the filesystems on B were
not cleanly unmounted before). I then shut the system down,
re-connected drive A and booted again.

In some cases, drive A was used to build the degraded array, and
in some cases drive B was used. I did not detect a pattern here.
This is not very convincing. One must keep in mind that this
series of events may also occur unprovoked: just think of an
unreliable USB hub.

You wrote that the "disconnected" drive would be marked as out of
sync at boot time. I presume this looks like this:

md: kicking non-fresh sda1 from array!

But by what criteria is a drive being categorized as "non-fresh"?

It looks outdated to me.
 

I found that Mesa 7.2 or newer is required for 3D, or at least a few specific
3D operations. Otherwise, fine.

My Radeon X300 needs to have Mesa configured with low-impact fallbacks
switched off (enable the "disable…" option using driconf); if you don't do
this, anti-aliased line drawing is enabled and that's *slow* (done using
software rendering, I shouldn't wonder).

If you're using KMS on Intel hw and you're using 2.6.32, boot with
i915.powersave=0 to avoid possible display problems after suspend.

No, I have not worked with them. However if you can give me a url to an image
please so. I am familiar with rack mounted equipment and their cooling
requirements.

The man asked after a single machine. He did not ask after a rack full of
them. If he had asked after a rack full I would have posted nothing unless
someone said leave the cover off. Rackmount is a separate issue. There has to
be no difference between the one on the lowest and the one on the highest
position in the rack.

For that I agree. Leave the cover ON! If you leave it off convection is just
going to make the one above it hotter and there is no place for the hot air do
convect away from it.

But he is asking after only one machine and not in a rack. Such a machine is
in a bad environment and has to make the best of being heated from above and
below. A single computer does not suffer from such disabilities.
 
 

Let me try some generalities here. ANY surface roughness s! Even the
bottom side of an MB is going to create turbulent flow and most of the heat is
on the other side. On the other side the components are much higher and cause
more turbulence and there is NOTHING you can do about it. The only better
cooling than native convection is going to be a 10 inch fan (Sears or
Walgreens not a computer product) ing directly on it from above.
