benchmarking large RAID arrays
by chrism＠imntv.com 14 Sep '06

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!

That's actually a very good point. The only thing is that the machine doesn't generate any revenue and so it'll heavlily depend on the price of the RAID controler really... I know there is none at the moment which is why I was looking into dd and tar. I've read that dd physically read/write every blocks of the disk whereas tar handles `zero-files` differently... Thus my question! > Never a good idea to run X when you dont need to.

But if you really wanted X check out > 'yum grouplist' and 'yum groupinstall "X Window System"' Good point, and I'm fully aware that one of the reasons win2k3 requires so much ram is the bloody UI! But I figured that with 2 ghz... I might give it a try! My concern tho' is really about configuring X... I've installed Centos on a test server here, and the X config is based on the server video/audio cards + monitor... What happens there there are none!!? :P Thx for your time... You made me realise that even RAID1 could be usefull (don't know why, I was under the impression that with only two disks raid wasn't worth it...!? Cheers Brad!

Hey John, that's a very interesting point you're raising. However how 'compatible' is openvpn with an M$ network? I mean is it a seemless integration or are there flaws? Having a quite Microsoft oriented network the idea sure would help in integrating new non-Ms servers to the network... Thanks for your input!
