CentOS 5 :: Monitoring And Configuring AHCI On Board Hardware RAID?
Nov 26, 2009I am using Centos 5.4 on an Intel DG451D Main Board. Two SATA drives in RAID1 mode via the main board's built in AHCI controller. It seems to work just fine but I would like to be able to monitor the state of my drives and controller, especially during a re-build and make configuration changes etc if possible, so new drives can be added etc from within the OS. Is there a way to do this within Centos or am I stuck with using just the BIOS configuration system? Apologies if this is a stupid question - I am pretty new to this and have spent several hours trying to find a solution to my question but to no avail.
View 1 Replies View RelatedHardware :: Best RAID Monitoring Utility?
Jan 18, 2010I am looking for recommendations on monitoring RAID array status in a "hardware RAID" setup (ie, using a RAID controller card or RAID-enabled motherboard).Here are some clarifying points:
1. OS is CentOS 5.
2. No drive lights are visible on the exterior of the system. So periodically checking for amber lights (indicating drive failure) is not an option.
3. No SNMP manager/collector is available. This question refers to local-system options. Not network-based options.

View 3 Replies View RelatedOpenSUSE Install :: Dmraid Vs Mdadm And RAID Status Monitoring?
Apr 22, 2011I'm pretty new to FakeRAID vs JBOD in a software RAID, and could use some help/advice. I recently installed 11.4 on a brand new server system that I pieced together, using Intel RAID ICH10r on an ASUS P8P67 Evo board with 2500K Sandy Bridge CPU. I have two RAIDs setup, one RAID-1 mirror for the system drive and /home, and the other consists of four drives in RAID-5 for a /data mount.
Installing 11.4 seemed a bit problematic. I ran into this problem: [URL]... I magically got around it by installing from the live KDE version with all updates downloaded before the install. When prompted, I specified I would like to use mdadm (it asked me), however it proceeded to setup a dmraid. I suspect this is because I have fake raid enabled via the bios. Am I correct in this? Or should I still be able to use mdadm with bios raid setup?
Anyways, to make a long story short, I now have the server mostly running with dmraid installed vice mdadm. I have read many stories online that seem to indicate that dmraid is unreliable versus mdadm, especially when used with newer SATA drives like I happen to be using. Is it worth re-installing the OS with the drives in JBOD and then having mdadm configure a linux software raid? Are their massive implications one way or another on if I do or do not install mdadm or keep dmraid?
Finally, what could I use to monitor the health and status of a dmraid? mdadm seems to have it's own monitoring associated with it when I was glazing over the man pages.

Aug 3, 2010I am trying to connect a RAID Box to the server via LSI 8880EM2 RAID controller.The raid box is FUjitsu Externus DX60 with raid 1 configured.The server is Fujitsu Primergy SX300 S5 with LSI 8880EM2 RAID card.The external raid box is being recognised by the raid controllers bios.
The server runs CentOS 5.5 64bit. I have installed the megaraid_sas driver from LSI website and MegaCLI utility but CentOS still fails to see the box.MegaCLI utility, when launched from CentOS, recognises the raid box, CentOS does not(no mapping being created in /dev).
I have also tried to create a logical RAID0 HDD on one physical HDD(as seen by MegaCLI) with MegaCLI utility in CentOS.The result was success and the new logical drive could have been used, but when restarting the server, the controllers' bios fails with an error (not surprised(one logical RAID0 on one physical HDD)) and configuration is being erased.
Has anyone tried connecting 8880EM2 controller to a raid box with raid configured on the box, running it all under CentOS and what were the results.
CentOS 5 Hardware :: RAID Or Non-raid HBA Recommendation?
Dec 10, 2009I am going to be using CentOs 5.4 for a home storage server. It will be RAID6 on 6 x 1TB drives. I plan on using an external enclosure which is connected via two SFF-8088 cables (4 drives a piece). I am looking to try and find a non-RAID HBA which would support this external enclosure and allow to use standard linux software raid.
If this is not an option, I'd consider using a hardware based raid card, but they are very expensive. The Adaptec 5085 is one option but is almost $800. If that is what I need for this thing to be solid then that is fine, I will spend the money but I am thinking that software raid may be the way to go.
CentOS 5 :: Looking For Apache Performance Monitoring?
May 19, 2011In Short: I want something that will show me which files and associated requested URLs are causing the highest load on our web server.
Verbose: We already monitor our Apache web server using Cacti, Nagios, and of course traditional nix commands, but I am looking for something specifically to take an Apache process ID and tie that to a users request for a specific file and URL. The great thing about something like this is that it would be able to show me the worse performing PHP files. Special bonus if it can store this data over time for reports.
I have been googling around for something like this but can't seem to find it. Bonus if it exists in Cacti or Nagios already and I'm just to blind. I started writing my own PERL script to do this, but have limited time to devote to this at work so if a solution already exists I'm game, else I'll just have to write it myself. I'm also worried about my own scripted solution in that it won't get it write because it will be leveraging the output of a specialzed apache log that records the PID and then doing a look up with ps aux looking for that PID.
Server :: Monitoring Users On Servers - Centos 5
Feb 28, 2010I'm looking for some sort of a way keep track of all of my users that are logging in to my server (centos 5), what I mean is this: at our firm we outsource some of our work (programing), now all of the developing is done under our servers, what I'd like to find is a way of taking all of the users log on time and display by days/weeks/months - so I could see how much did everyone had put in. Another thing that I'm looking for is a way to monitor an ongoing session and record user activity, now I've seen ObserveIT, but it doesn't support Linux agents as of today.

CentOS 5 Hardware :: SW RAID - Raid Devices Larger Than Total Devices
Dec 7, 2010I'm working on a server and noticed that the to RAID5 setup is showing 4 Raid devices but only 3 Total devices. It's on a fully updated CentOS 5 system that only has three SATA drives, as it can not hold anymore. I've done some researching but am unable to remove the fourth device, which is listed as removed. The full output of `mdadm -D /dev/md2` can be see below. I've never run into this situation before.Anyone have any pointers on how I can reduced the Raid Devices from 4 to 3? I have tried
mdadm /dev/md2 -r failed
mdadm /dev/md2 -r detached
but neither work and since there is no block device listed I'm not quite sure how to get things back in sync so it's only seeing the three drives.

Version : 0.90

CentOS 5 Hardware :: Error Installing CentOS 5.2 On ICH7R With 4 SATA HDDs RAID 5?

Jan 13, 2010My problem is that I'm trying to install CentOS 5.4 x86_64 DVD ISO on Supermicro X7SBI server with installed Adaptec RAID 3405 controller.
I created RAID 5 array and is working fine (adaptec status says Optimal) but I can't install CentOS to that array (1.5TB size).
Whenever I try to install with: linux dd
I'm asked for a driver, which I have downloaded from Adaptec site and extracted contents to USB drive (in installation found as /sba1) which has now a lot of IMG and some ISO files on it.
I try to load (I simplified names) RHEL5.img, CENTOS.img... with x64 names (one exact name: aacraid driverdisk-CentOS-x86_64.img) and I always get the error message: "No devices of the appropriate type were found on this driver disk"
This is going on for a week now and I can't find the right driver or something I'm doing wrong to get install done.

CentOS 5 Hardware :: Intel S5000Vsa And RAID Driver With Centos 5.4?
Dec 31, 2009I've a Centos 5.1 server on S5000vsa Intel board with 6 bay HD in raid 1 mode (2 HD), and working fine until I've decide to make a yum update. Today the Centos is 5.4 but seems necesssary to upgrade the megasr driver for the raid function (i.e. , is not possible to contact the raid firmware trought Web Console 2). I've download the last megasr driver from Intel and I follow the instruction to upgrade the driver with s.o. installed, but when I start the server and choose via grub the new img boot file, the display show :
megasr.ko invalid module format -1 and stop. The linux version is the same in the machine (uname -a) and from the driver (2.6.18-164.9.1.el5). Another question : in Intel instruction spoken about megasr.o , but on img file I found a megasr.ko . I think instructions referre to old linux 2.4

CentOS 5 Hardware :: How To Install CentOS On RAID 5.I
May 10, 2011I have DELL R310 server with PERC 200H controller and RAID 5 configured already.This is my first time I want to install CentOS and seems like a new challenge for me I've read some articles on Wiki and posts on this forum and didn't find any information how to install CentOS on RAID 5.I only noticed that if there is fake or software RAID1 it should be switched off and made by OS configuration.I think PERC 200H is separate controller so RAID 5 is hardware RAID, is there anybody who can confirm ?My problem is that when I try to install CentOS it doesn't see any hard disks ... I looked for drivers on DELL web site and there is driver for Red Hat 6. I tried to install it using linux dd command but it doesn't recognize. Is there anybody else who met such problem ?

CentOS 5 :: Use RAID Without Exim?
Apr 7, 2009I installed CentOS 3 and during the installation, I configured the disks using 'software RAID'. Then I installed my /data partion on /dev/md0. Everything seemed fine however I install a extremely bare installation of CentOS 5.3. I don't select any packages during the install process which includes anything under the 'base' package software selection. I then noticed that because I configured my system with 'software RAID', it found 'mdadm' as a dependency package and installed 'mdadm' however this also then grabbed 'exim-mta' package so now I have 1/2 a mail server installed simply because I have software RAID on my box. I am not permitted to have anything beyond 'Postfix' MTA on my LAN. I don't want Postfix any ways on this machine so is there a way I can install CentOS 5.3 cleanly w/o packages I don't want or need? I am sure I can 'yum remove exim' and that in turn will remove 'exim & mdadm' from my machine however I would like to start fresh.
