CentOS 6.0 and 3ware 9650SE series RAID Performance
Hello, Does anyone have experience using a 3ware 9650SE series raid controller on CentOS 6.0? I am getting very sporadic throughput with moderately sized files (0.5-2GB) on ext3. I have tried most of the mount time tuning options: * noatime * trying different journal types * setting commit=120 - helped a little Even after these optimizations it doesn't seem like the raid array is working

smartd and 3ware 9xxx configs
I'm looking to do a bit more monitoring of my 3ware 9550 with smartd, and wanted to see what others were doing with smart for monitoring 3ware hardware. Do you have the smartd.conf configured to test, or simply monitor health status? Are you monitoring the drive as centos sees it (/dev/sdX) or are you using the 3ware /dev/twaX for monitoring? Opinions and discussions are welcome :-P --

smartd and 3ware on centos5
Hi, I've CentOS5 box with 3ware RAID controller in it. I can't get the tw_cli command line tool to work, and smartd also barks on me. The tw_cli simply doesn't see the controller, no errors logged anywhere. When starting smartd, it is much more verbose. I'm getting a bunch of messages like this: Oct 9 22:15:15 toporko kernel: program smartd is using a deprecated SCSI ioctl,

use of lm() and poly()
Hi all, I want to fit data called "metal" with a polynominal function as dP ~ a.0 + a.1 * U0 + a.2 * U0^2 + a.3 * U0^3 + a.4 * U0^4 The data set includes, the independant variable U0 and the dependant variable dP. I've seen that the combination of lm() and poly() can do that instead of using the nls() function. But I don't get how to interpret the results from the linear

Postfix mail server procedure
CentOS Community, I was wondering if anyone had a good resource or procedure for a step by step in installing a mail server with Centos. There ARE documents on google, however almost all that i've found were outdated from 2005. Does anyone know where I can find this type of document for a mailserver Postfix + MySQL + SpamAssassin + ClamAV + Squirrelmail + Postfixadmin, etc?

LVM question
CentOS Community, It is to my understanding that the /boot partition should never be placed on LVM and should be a physical partition on the hard drives (or on top of a RAID array). Is this an accurate statement? Also please advise if the SWAP filesystem is safe to be placed under LVM, or if this should be a hard partition / hard limit as well. I am unsure if boot issues or any filesystem issues

I know years ago this wasn't possible without a program like ChiliASP, but noow I heard rumor that apache might have

Pseudo-random numbers between two numbers
I would like to generate pseudo-random numbers between two numbers using R, up to a given distribution, for instance, rnorm. That is something like rnorm(HowMany,Min,Max,mean,sd) over rnorm(HowMany,mean,sd). I am wondering if dnorm(runif(HowMany, Min, Max), mean, sd) is good. Any idea? Thanks. -james

6.2 How to change hostname for each individual IP
Good day, I was wondering if there was a way to change the hostname for each individual IP address allocated to a system. For example if only one NIC card is being used (single port) and the hostname of the machine is "example.example.org", this hostname is being displayed for all applications no matter what IP I set the application to BIND to. My server has multiple IP addresses
