SiI 3114 and RAID
by Florin Andrei 23 Feb '07

23 Feb '07

I've two machines with almost identical hardware (slightly different CPUs). The SATA/RAID controller is SiI 3114. One of the servers was installed a while ago by someone else, it's running Fedora Core 5 and RAID is enabled: # df -m Filesystem 1M-blocks Used Available Use% Mounted on /dev/dm-6 125931 2990 116441 3% / /dev/dm-1 99 13 81 14% /boot tmpfs 1012 0 1012 0% /dev/shm /dev/dm-2 9917 151 9254 2% /tmp /dev/dm-3 9917 237 9168 3% /var # cat /etc/modprobe.conf | tail -n 1 alias scsi_hostadapter sata_sil I installed CentOS 4.4 64bit on the other system, but I could not enable RAID. The installer was always seeing 2 separate drives instead of one RAID device. Was it my mistake? Did I not enable the proper settings in the BIOS? (I tried quite a few different settings) Or is it perhaps that the CentOS kernel does not have the proper drivers to support SiI 3114 in RAID mode? -- Florin Andrei http://florin.myip.org/

RTL8169S-32 card
by Eduardo Grosclaude 23 Feb '07

23 Feb '07

Hello, I am building a DRBD cluster with CentOS 4.4. Both nodes have RTL8169S-32 cards, Pheenet branded. I'm getting no more than 185 Mbps with the driver selected at installation (r8169). Downloading Realtek's r1000 climbs to some amazing 200Mbps. I am measuring performance with iperf, host to host, with a cat5e direct cable some 2.5ft long. Maybe disk I/O will be the bottleneck in my use case but anyway I feel performance is well under par with this cards. Is something wrong in my measuring setup? Am I right in expecting more speed? Has anyone had this same experience? Resources to compatible Gbps cards? Thanks! -- Eduardo Grosclaude Universidad Nacional del Comahue Neuquen, Argentina

CentOS 4.4-IBM Netvista Performace Problems, help needed.
by Chuck Mattern 23 Feb '07

23 Feb '07

I've got an odd situation that I need some advise on. I have two computers that I am planning to use as a cluster. I initially started with some left over Compaq Presairos with 667MHz CPUs. I loaded CentOS 4.3 and later updated to 4.4. Things ran normally, albeit slowly. I had an opportunity to upgrade to a pair of IBM Netvistas with 2.26 GHz CPUs, I did this by transferring the 160GB Western Digital IDE disks and NICs but did not re-install the OS, just migrated the disks. Since then they have had the following symptoms: -Systems frequently boot faster than the disks can be spun up and have to be soft booted to recognize and boot from the disks. -Systems will bog down critically after approximately 24 hours loosing system time at an increasing rate, ofrr instance a for loop that runs date, hwclock ans then sleeps for 10 minutes will show time in sync for the first few hours then the system time will begin to fall behind at an increasing rate, after 24 hours the system time essentially stops elapsing. It almost feels like the box has trouble processing interrupts. Once it gets to this state performance becomes very sluggish, for instance top will take up to 90 seconds to display it's first screen and will not update on it's own, only when Enter is depressed. At times top will show 0's across the utilization line for everything including idle. I have gone as far as to boot one of the boxes into single user mode and run the date/hwclock loop and even in that state the system will bog down and gradually stop elapsing time after 18-24 hours. Even shutting down is impacted. A reboot will take well over an hour to process. I had a copy of Ubuntu on my desk and have booted into that distro from cd and it passes the date/hwclock test (actually lost 2 seconds over a 24 hour period but I can live with that via ntp). I'm downloading a copy of the CentOS live 4.4 cd and will try this with that as well but at this time does anyone see that this could be something other than a disk incompatibility with the newer systems? Should I try re-installing? If it is the disks, any thoughts on something I could try to avoid buying new disks (I have tried setting the BIOS to both the high performance and legacy disk modes (not entirely sure what's behind that IBMism)). Regards, Chuck

How do I build a modified rpm (Another newbie question)?
by Mark Hull-Richter 23 Feb '07

23 Feb '07

I made a minor change to the XFS package (in the unpacked source files), but I can't figure out which rpmbuild option to use to build from that changed source file (instead of re-unpacking all the source files, overwriting all the source files, etc.). Please assist/explain. Thanks.

Centos firewall/router issue
by Dustin Krysak 23 Feb '07

23 Feb '07

Good day everyone. Today has been "one of those..." days. So I have a feeling this is just a brain lapse here. At any rate, I am setting up a firewall/router using centos 4.4 (minimal install, yummed up to date). I have in fact enables V4 ip forwarding (by editing /etc/sysctl.conf) and rebooted the system. I use fwbuilder for my rules, and at this point have a next to nothing set of rules. a DHCP server is also residing on this router. Now the firewall can get pings back from various sources on the net by IP and by host name. The firewall can also ping the workstations, and the workstations can ping hte firewall (VIA the internal IP). The work stations are in fact getting proper IP info from the DHCP server (I have released and renewed it many times as well as rebooted). Now the issue is, I can not get out of the internal network to the internet for any traffic. Pings (by ip and name), web sites, etc. It "seems" like the traffic is not being forwarded, but I have run the following command to confirm the ip forwarding is on: # cat /proc/sys/net/ipv4/ip_forward And I do in fact have a "1" in there. Did I miss one little step somewhere? I have set these things up before without issue, so I suspect I am over looking a little step here. Ideas?

How did you manually mount it?
