Hyperthreading ON causes OOPS on boot
by Mark Strong 15 Sep '06

15 Sep '06

I just tried to install CentOS (x86_64 4.4 and i386 4.3, not both at once, when I found the 64bit version didn't boot, I tried the 32bit version, same result) on a dual Naconda Xeon system. I get an OOPS just after the IDE info is printed on the screen during boot (this is booting off the CD during the install phase). After mucking about with the bios settings (and many reboots later), I found with Hyperthreading off it boots and installs ok (installed the x86_64 version once I got it going). After YUM updating, and getting a new kernel I thought I'd try turning the Hyperthreading back on, crashed in the same spot during boot. Since I'm going to use it as a MySQL server and Hyperthreading seems to make MySQL slower, it not a problem that it won't work with Hyperthreading enabled, but it would be interesting to know why. Any ideas??? Its a ASUS NCL-DS with Dual 3.4G Xeons, 8G of DDR2 ram, and a 3ware raid controller 8500LP.

VPND
by Guillermo Garron 15 Sep '06

Hi, I have one FC5 server and one CentOS 4.4 server and I want to stablish a VPN between them, i have read that VPNd could be an option, anybody know where do I find the rpm for CentOS or with repository should i have to install in order to get it? Also if somebody has some other software that recommend me to stablish a VPN -- Guillermo Garron "Linux IS user friendly... It's just selective about who its friends are." (Using FC5, CentOS4.4 and Ubuntu 6.06)

Anyone using fuse and/or sshfs under Centos 4.4?
by Dave Hatton 15 Sep '06

15 Sep '06

Hi A search of google failed to show any prebuilt rpms for sshfs and fuse. I do see that fuse support is in 2.6.14 kernel which isn't a whole lot of help. Before I dive headlong into this has anyone successfully built fuse/sshfs against Centos 4.4. If so would you share your experience? Thanks Daveh

RE: [CentOS] backup server..

Hey Tim, Found this during my evening reading! http://www.dur.ac.uk/a.d.stribblehill/mirrored_grub.html "The purpose of this document is to suggest a way of configuring grub on a system where the operating system is mirrored between two disks, so that if the first disk fails completely, the system will boot automatically from the second disk." Hope this helps! Seb. -----Original Message----- From: centos-bounces(a)centos.org [mailto:centos-bounces@centos.org] On Behalf Of TimJowers(a)Yahoo.Com Sent: Thursday, 14 September 2006 10:49 PM To: CentOS mailing list Subject: Re: [CentOS] backup server.. Maybe someone can clear up the grub conf for me. Has anyone gotten this to work: two IDE/ATA drivers. Slave is a spare duplicate of the master. Goal is to be able to boot to Spare at any time and run it instead. What step am I missing? When I tried to duplicate a system I failed using this method due to the /boot configuration being specific to the disk layout in the box. That is, if I copied disk A to disk B and then wanted to boot to B I believe I would have to remove A and strap B as the master. Combined SCSI and ATA totally failed on GRUB knowing which disk is which. Ended up having to first install the target slave disk and then moved the disk. Copied everything except /boot. My impression is RAID is the only thing which would work. My goal was actually to create several systems based on the install of one master system. The other systems had random numbers of disks and such. The only way i got it to work was Ch1Master had to be the boot disk in all of them. I mucked around with /boot/grub/grub.conf and device.map to no avail.

Re: CentOS-announce mailing list
by Neal Macklin 14 Sep '06

This is a small thing; apologize if it's been previously discussed. In user options for the CentOS-Announce mailing list options page: http://lists.centos.org/mailman/listinfo/centos-announce you can subscribe to architectures of interest. To receive posts about the i386 architecture, for example, the mailing list pattern (as a regexp) is: CentOS.4.i386 whereas the one for all 4.x architectures is: CentOS.4 The problem is that if you are only subscribed to the i386 subset you will miss architecture independent announcements, such as the recent ones regarding CentOS 4.4 availability. A solution would be to include a pattern for all relevant architectures on the subject line for general release announements, which would allow the existing regexp's to work. However this would make subject lines too long as John pointed out. Better might be to modify the existing regexps to additionally accept subject lines where no architecture is shown. Thanks, Neal

benchmarking large RAID arrays

I'm just wondering what folks are using to benchmark/tune large arrays these days. I've always used bonnie with file sizes 2-3 times physical RAM. Maybe there's a better way? Cheers,

bind errors after yum update to 4.4 CentOs
by eric＠austinconventioncenter.com 14 Sep '06

14 Sep '06

I recently upgraded my name server to CentOs 4.4 from CentOs 4.3 and bind was one of the many packages upgraded. I get the following message when performing an rndc reload " rndc reload rndc: connection to remote host closed This may indicate that the remote server is using an older version of the command protocol, this host is not authorized to connect, or the key is invalid." which odd as I am doing this on the master dns server for the zones. I made sure that my key in rndc.key and rndc.conf match. Anyone else having similar issues? Thanks, Eric

backup server..
by Sebastien Tremblay 14 Sep '06

14 Sep '06

Hi, I've been playing with CentOS quite a bit lately (and I must say it's growing on me!! :) and I was now able to convince my boss that we could get a box and gradually start migrating our hosting from win2k3 to centos. So anyway, I've got a new box at the colo ready up and running - P4 3Ghz w/HT 2Ghz RAM 2x70Gb HDD, running Centos4.4 fully up-to-date. Now my two questions are; (1.) In terms of backup, I'd like to have a cron sending out an nightly incremental backup of user files. I'd also like to have HDA to be copied backed up entirely (maybe weekly) onto HDB (were're not going to use 140GB anyway!) so that is hda crashes, I`d swap both of the hdds and boot from the backup. Now for that second step, I was reading that dd was quite CPU intensive? Would there be other alternatives? Advices on doing backups? (2.) I've got no physical access to the box, and the box has obviously no video or sound. Considering this, would it possible to remotely administer the box using VNC in a GUI environment? - I figured 2Ghz could probably handle me starting x sometimes...! So if possible.. How would I do it? I`m assuming there are no `yum install x`.... Anyway.. Thanks for any input you may have on the both topics!
