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,

I was asked this question today and frankly, I didn't know the answer. So I thought I'd post it here.... If you don't need to access greater than 4GB RAM, is there any benefit to running the 64-bit version of CentOS vs the 32-bit one? That's assuming, of course, that the target machine utilizes a 64-bit capable processor. I hadn't seen any noticeable difference, but I

I checked Best Buy again. The second system I recommended is in stock at the Best Buy in Warwick. It's on sale for $353. :) http://www.bestbuy.com/site/olspage.jsp?skuId=8254569&type=product&id=1169512522677 I'm thinking about getting out of Dodge today to unwind so if you pick it up early today I can come up and help you install it and then just come home later in the day.

I have been trying to install CentOS 4.1 on a new server today. The installation went fine but the system doesn't boot. It doesn't even get to the Grub screen. The system has a 3ware 9500 series controller and 12 250GB SATA disks which are configured for RAID5 with one hot spare. I searched on the web and noticed that this is a Grub (and Lilo) limitation. Is there any way around it other

Anyone know of any PCI-e hardware RAID adapters? -- My "Foundation" verse: Isa 54:17 No weapon that is formed against thee shall prosper; and every tongue that shall rise against thee in judgment thou shalt condemn.

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

Hi folks, I have just installed a PCI SATA controller based on the SIL3112A chipset into my Centos-3 (latest kernel patches applied) system and moved an existing (not the boot disk) SATA drive from the onboard controller to the SIL-based one so I can setup software RAID with two 300GB drives. Kudzu/Linux found the controller and drives straight away and they've appeared as 'hda' and

I''m still using CentOS 3.3 as our install mechanism, then adding some packages from a tarball of RPMs we need. Then I run # yum update yum which sometimes takes a while. Yesterday it took many hours. I like to run these from behind a firewall in our office before taking the server to the datacenter, but the delay meant a whole day''s delay in our trip to the datacenter

All, I would like to announce our Official CentOS CD/DVD Vendor Program. We currently have 3 vendors, and 2 more who are putting together their information. (Not bad ... the official program has been going for less than 12 hours :) The details of the program (how to get in it, what they give back to the CentOS Project, etc.) are here: http://www.centos.org/images/CentOS_CD_Vendors.pdf Here is

Anyone know where I could find this package for Centos 4.4 x86_64? I've googled all over and haven't been able to find anything more current the 0.8.4a. I'm not much of a programmer, but if someone could point me at a "packaging for dummies" perhaps I could have a go at creating a package if one doesn't already exist? Cheers,

Seems like a nice lightweight server platform for non-disk-intensive apps. Cheers,

Is anyone having issues with these particular cards (especially the newer SATAII variant) and the stock CentOS kernels? Are they well supported enough such that a "yum update" suffices to keep them synced up with patches without having to hand edit the kernel or build special modules from 3Ware each time? Cheers,

Postfix appears to be running normally and is accepting/receiving mail as usual, but... I'm seeing lines like this in the message log: Sep 1 06:55:23 fender postfix/smtpd[11969]: sql_select option missing Sep 1 06:55:23 fender postfix/smtpd[11969]: auxpropfunc error no mechanism available Those seem to be sasl related, right? I'm not using sasl support (yet). Any clues to this

Is it possible to create an alternate list for the people who insist on spending their days posting long-winded political commentary and opinion? Maybe something like centos-offtopic? Reading the list has gone from "fun" status to "chore." Just a suggestion. Cheers, C

I've got a brand new .5U P4 system running several (I think) Seagate 80gig SATA drives. I tried to copy data from the first drive (sda) to the second drive (sdc) and was only getting about 1.7megs/sec. So I figured DMA was off. And this is what happened when I typed "hdparm -d1 /dev/hdc": /dev/hdc: setting using_dma to 1 (on) HDIO_SET_DMA failed: Operation not permitted

I have heard rumblings about the new kernel for 4.4 A change was made to the kernel for disk I/O to make it better/faster. I havnt heard/seen anything about what that really translates to. Any thoughts/opinions on this. jerry -------------- next part -------------- An HTML attachment was scrubbed... URL:

Gents, Under 4.3 and the associated kernel it took 17 seconds to recompile my entire application on my amd 4800+ X2. Down from 1 minute and 20 seconds on my old platform. I just tried under the new 2.6.9-42 kernel and it is 15 seconds. So that modification to the kernel for disk improvement seemed to help my compile time... Just sharing... Great work on 4.4. Jerry
