I have two identical servers. The only difference is that the first one has Maxtor 250G drives and the second one has Seagate 320G drives. OS: CentOS-4.4 (fully patched) CPU: dual Opteron 280 Memory: 16GB Raid card: 3ware 9550Sx-8LP Raid volume: 4-disk Raid 5 with NCQ and Write Cache enabled On the first server I have decent performance. Nothing spectacular, but good enough. The second one

I've been planning to build a dual Opteron server for awhile. I'd like to get people's suggestions on a suitable motherboard. I've looked at the Tyan K8SE (S2892) and K8SRE (S2891) but would like to find more Linux-specific experiences with these boards. Some features I expect are at least 4 SATA (SATA-300?) ports, serial console support in the BIOS, USB 2.0 and IEEE-1394

I know there are a few 3Ware fans here and I was hoping to find some help. I just built a new server using a 3Ware 9550SX-4LP with four disks in raid 5. The array is fully initialized but I'm not getting the write performance I was hoping for -- only 40 to 45MB/Sec. 3Ware's site advertises 300MB/Sec writes using 8 disks on the PCI Express version of this card (the 9580 I think.)

I had my eye on the Tyan dual-Opteron mobos for awhile. I tried to find a posting *anywhere* sharing experiences with these boards under Linux. No such luck. So placing myself under the heading "Where Angles Fear to Tread," I went ahead and built a system anyway. Here's what I've learned. The specs: Tyan Thunder K8SE S2892, BIOS 1.01 2x Opteron 270, 2Ghz Dual-Core, retail

I'd like to add a page for the Realtek r1000 NIC driver for the RTL8110SC (and others) chipset. This driver is not included in the kernel. I've previously posted to the general mail list: http://lists.centos.org/pipermail/centos/2007-February/075383.html I'm guessing this would go in the HardwareList section. Otherwise a page titled 'Realtek r1000 Driver' would work. my

I'm starting a project to build a MythTV box for my living room. Anyone else currently working with MythTV on CentOS 4? Here are some of the gotcha's I've worked through so far: - I was originally planning on using KnoppMyth. But their CD appears to be only for i386. Without realizing it, the P4 CPU I picked is one of the newer ones with the x86_64 extensions. It won't boot

Running CentOS 5 (long story, will be updated some day). A 5 yr old Dell PE R415. Whoever spec'd the order, they got the cheapest, embedded controller. Push came to shove - these things gag on a drive > 2TB. So, we bought some PERC H200's for it, and its two mates. This morning, I brought the system down, and put in the card, and moved the SATA cables. This did not end well. The new

Is it possible to boot the Live CD through PXE? I've tried using Red Hat's PXE setup tool but have been unsuccessful. Thanks, Kirk Bocek

I made some tests to see how ext3 reiserfs 3.6 and jfs survive disk errors. The test is simple: format a partition, copy the kernel source, unmount and and do ?dd if=/dev/zero of=/dev/hdd bs=512 count=100000 seek=30000? to simulate a disk surface damage and then run fsck. seek=30000 ? this must be the second half of journal in reiserfs and ext3, for jfs I don't know Result: jfs: ---- total

We are looking at implementing a Linux box running samba in the near future with about 1TB of disk online. The purpose of this box will be for basic file and printer sharing needs. I am doing research on the different journaling file systems avaible in RH 7.3 and up (ext3, reiserFS, and JFS) and was wondering if anyone has had any real world experience with them (mostly reiserFS and JFS) and

After reading this article: http://www.theregister.co.uk/2005/08/31/blocking_chinese_ip_addresses/ I got to thinking that there is really no reason for *any* traffic to hit my servers that comes from anywhere outside North America. So I wrote the perl script at the end of this posting to extract selected IP ranges posted at iana.org and convert them into iptables rules blocking any traffic

Since updating to 4.2 my Opteron server has been flooded by messages like: audit(1129565701.837:155): user pid=4700 uid=0 auid=4294967295 msg='PAM session open: user=root exe="/usr/sbin/crond" (hostname=?, addr=?, terminal=cron result=Success)' to both /var/log/messages and the kernel ring buffer. Looks like they are being generated by cron jobs being run on the server. Does

Howdy, It appears that CentOS 5.2's support for the RTL8111B/C chip is incomplete. The wiki has some blanket statements regarding this support: http://wiki.centos.org/AdditionalResources/HardwareList/CentOS5/RealTek/r1000 http://wiki.centos.org/AdditionalResources/HardwareList/RealTekRTL8111b I could dive in an make the changes *I* think need to happen but I'd like to talk to people
