[PATCH v2] x86/ACPI: invalidate BGRT if necessary
Since the image pointed to may live in boot services memory (which we

- defer adding boot services memory until Dom0 indicates it is safe to
do so, or

Tuning system response degradation under heavy ext3/2 activity.
Hello.
I'm looking for assistance or pointers for the following problem.

Hi Hemant,
As I suspected, the code broke when I got to the line:

CentOS 3 - I/O performance with Promise HW RAID

We have CentOS 3.6 x86_64 running on a server with dual 2.2GHz
Opterons and a Promise UltraTrak RM8000 connected via an Adaptec SCSI

is it possible to resive a PV in LVM and add more LV's ?
Hi all
I have a remote server (i.e SSH access only) which was incorrectly
partitioned and I urgently need to get it up and running. It's got a 500GB
HDD, but the PV is only 10GB big, so I can't add more LV's to to. P.S. This
is on LVM, btw.

Promise box is using Gigabit Ethernet, and is the only device on that

How to interpret the output of 'iostat -x /dev/sdb1 20 100' ??
Hi,
I'm a newbie to tool 'iostat' and I've read the
manual for iostat several times. But it doesn't help.
I still get confused with the output of 'iostat', the
manual seems too abstract, or high-level, for me.
Let's post the output first:

I have some problems regarding a GLM - repeated measures analysis.
I want to test overall differences between AgeClass and Treatment (between

I'm new to the whole R-thing as a replacement for Matlab, not disappointed sofar ;)
I found out how to make nice looking boxplots, but i also would like the make a boxplot with 5% and 95% instead of the standard 25 and 75% quantiles.

Dovecot performance issues with many writes
We are currently experiencing performance issue with our Dovecot system
which we believe is caused by excessive writes to the dovecot files. The
confusing thing is that we are seeing more writes than reads on our Dovecot
volume when you would assume that most of the IO should be reads from
customers checking their mail.
We're seeing reads vs. writes similar to the following:

steadily increasing/high loadavg without i/o wait or cpu utilization
Hi all,
I just installed centos 5.4 xen-kernel on intel core i5 machine as dom0.
After some hours of syncing a raid10 array (8 sata disk) I noticed a
steadily increasing loadavg. I think without reasonable i/o wait or cpu
utilization the loadavg on this system should be very lower. If this
loadavg is normal I would be greatful if somone could explain why. The
