I run a decent amount of 3ware hardware, all under centos-4. There seems to be some sort of fundamental disagreement between ext3 and 3ware's hardware RAID5 mode that trashes write performance. As a representative example, one current setup is 2 9550SX-12 boards in hardware RAID5 mode (256KB stripe size) with a software RAID0 stripe on top (also 256KB chunks). bonnie++ results look

We have a server with about 6x750Gb SATA drives setup on a hardware RAID controller. We created hardware RAID 5 on these 6x750GB HDDs. The effective size after RAID 5 implementation is 3.4TB. This server we want to use it as a data backup server. Here is the problem we are stuck with, when we use fdisk -l, we can see the drive specs and its size as 3.4TB. But when we want to create two different

I have a centos 4.2 32bit app that when installed on centos 4.2 64 bit box and try to run it I get "libxml2.so.2 not found". however if I "rpm -qa | grep libxml2" it shows up just fine. How can I get this app to run on the 64bit box (without recompiling yet). The recompiling will come someday... right now I just would like it to run. Thanks Jerry -------------- next part

Back in the day (read: before the latest firefox update), I used to be able to ssh to a remote box, run 'firefox -local', and have that box fire up its own firefox session even if I was running firefox on the system from I which I sshed. Those days seem to be gone. No matter what I try, if I've got firefox running on my local desktop, the remote firefox command just fires off

I need a SCSI card to attach a tape library to my system. I am looking at the Adaptec 29320A-R. Can anyone confirm that this card will work with the stock CentOS 4 kernel? -- Bowie

I am planning to build a server based on the SuperMicro X7DBE+-O motherboard. This server will have two dual-core Xeon processors and a 3ware 9550SX raid card. Has anyone built a server based on this motherboard? Are there any issues with the smp/dual-core support in CentOS4 that might cause problems? I appreciate any input. I'm just looking to find out about any possible problems before

Hello everybody. I have a problem setting up gluster failover funcionality. Based on manual i setup ucarp which is working well ( tested with ping/ssh etc ) But when i use virtual address for gluster volume mount and i turn off one of nodes machine/gluster will freeze until node is back online. My virtual ip is 3.200 and machine real ip is 3.233 and 3.5. In gluster log i can see: [2011-06-06

Hi, I have alot of kickstart and scripting going on as I provision lots of machines, and every now and then I run into a pesky machine or three that's still got that Adeptec zero-channel RAID card sitting on the board. Normally I like to rip it our and throw something more robust in, but if it's a cache machine or whatever, I leave it in. It makes my kickstart file useless until I

greetings would someone please point me to an excellent server exercising, stressing, and/or testing program that will run on centos 4? i want one that will not out and out destroy a machine so to speak... ...meaning testing is one thing, yet pounding a box in the hard drive department over and above the cause or unnecessarily does not appeal to me. fyi the box i want to test/stress this time

We are strategizing a set of backup servers and I have been trying to deduce wha the maximum size of each RAID 5 array should be to match the OS we are using. We are currently running CentOS 4.3 64 bit. We have planned a 2 TB RAID 5 array for testing but we will need to set up several larger ones for production. I have poked around and I see people mention limits like 2TB max file size and 32TB

Has anyone here benchmarked 64-bit 4.2 against a dual core opteron (or Athlon 64x2) vs a pair of physical single-core opterons? It's that time of year again....ordering new workstations. 8-) Cheers,

Dear list, I am planning to buy a new server -because the new Core2 Duo based Xeons (5100 series) are considerably faster in some scenarios than Opteron machines while not beeing more expensive, I would like to hear some real-world experiences from people who have installed CentOS 4.3 or 4.4 on such a setup. Specifically: CPU: 2x Intel Xeon 5100 2GHz Board: Intel S5000 chipset RAID5:

I'm trying to setup a simple NFSv4 mount between two x86_64 hosts.

I've been having no end of issues with a 3ware 9650SE-24M8 in a server that's coming on a year old. I've got 24 WDC WD5001ABYS drives (500GB) hooked to it, running as a single RAID6 w/ a hot spare. These issues boil down to the card periodically throwing errors like the following: sd 1:0:0:0: WARNING: (0x06:0x002C): Command (0x8a) timed out, resetting card. Usually when this

Hello, I've got a centos 4.4 box and i'd like to make some rpms for it. My first task is to recompile an srpm removing some options to customize it. I tried rpmbuild, which worked on a fedora install, but that command wasn't available. What rpm do i have to install to make rpms? I've got rpmdb, rpm, and rpm-libs already installed. I thought the missing one was rpm-utils,

Hi, has anyone enabled using centos, the proliant functionality of "teaming" the two integrated network cards, to be seen as one by the network switch?

We have an appliance that uses the CentOS 4.4 Plus kernel with XFS on an EMC RAID array that performs about ? or less as well with cached i/o than with direct i/o. With direct i/o we get about 32Mb/s throughput or better, but if we enable the cache for the EMC RAID, we only get 8Mb/s or less. This doesn't happen if we use JFS, where we get a little less than 32Mb/s throughput with or without
