iSCSI disk preperation
by Jason Brown 09 Feb '11

09 Feb '11

I am currently going through the process of installing/configuring an iSCSI target and cannot find a good write up on how to prepare the disks on the server. I would like to mirror the two disks and present them to the client. Mirroring isn't the question, its how I go about it is the problem. When I partitioned the two drives and mirrored them together, then presented them to the client, it showed to the client as a disk out no partion on it. Should I partition the drive again and then lay the file system down on top of that? Or should I delete the partitions on the target server and just have sda and sdb mirrored, then when the client attaches the disk, then partion it (/dev/sdc1) and write the file system. Thanks

Printer-Problems
by Timothy Kesten 09 Feb '11

09 Feb '11

Hi Folks, fresh CentOS 5.5 x86_64. One USB-printer connected (HP Business Inkjet 1200) Printing from localhost:631 (Testpage) works. But no from any application. From OO only the message: printer-problem - no more. Second printer is from far (Cupsd) in the network. Works well. But what's about the local printer? Any hints? Thx Timothy

Re: [CentOS] Fan speed control on Supermicro X8DAL board with CentOS

I've since gone back to CentOS-5.5 on the box (since it's not fully built anyway) and added the SuperoDoctor monitoring utility after resolving a couple of dependencies like SNMP and the correct kernel driver. I sent an enquiry to the Supermicro support folks, and they jumped on it right away, which impressed me. They wanted a screenshot of SuperoDoctor to try to analyze the problem. I don't think it's a case of a kernel module getting in the way because this issue crops up even during the BIOS boot process, and happens randomly if I run memtest86 as well. Sometimes the fans jump to light speed, other times not. I'm beginning to think it's either a bug in the latest BIOS or a sensor chip problem. Even when the CPU temperatures are reported as "Low", the fans run full speed most of the time. The exhaust air leaving the box is almost cool, so ambient temperature is ok. I'll give the Supermicro support folks some time to sort this out, since I'm still waiting for CentOS-6 anyway. Chuck

Configuring a cluster

08 Feb '11

Dear Centos users, I am not sure if this the correct place to post but it seems sensible. I have an 8 node cluster which I want to install/configure Centos. As I am not a sys-admin, can anyone advise me on what I should do? Any suggestions appreciated. Thank you.

How and when are the sound modules loaded at system boot time on CentOS 5?
by James Pearson 08 Feb '11

08 Feb '11

I've been trying to work out how the various sound modules get loaded at boot time on CentOS 5 - but I can't find anything obvious under /etc/rc.d/ CentOS 4 did this in /etc/rc.d/rc.sysinit - but there is nothing equivalent in CentOS 5 Does anyone know how these modules get loaded? Thanks James Pearson

premature question on 5.6
by Jerry Geis 08 Feb '11

08 Feb '11

What will be the correct way to migrate ext3 to ext4 going from 5.5 to 5.6? Will something after the update ask if you want to migrate the file systems? Looking forward to some file system speed ups with large files. Thanks Jerry
