CentOS 5 Hardware :: Install With Dell Poweredge Expandable Raid Controller?

Oct 4, 2010

I am trying to install Centos onto a Poweredge 2650, with Dell Poweredge Expandable Raid Controller. I have 5 SCSI disks installed, and have created and initialised 2 logical volumes via the SCSI controller setup utility (Ctrl M after boot). After reboot the system reports two logical volumes present.

The Centos installer cannot find any disks when it gets to the disk partitioning/setup step. It reports no disks present. Do I need a specific driver for this controller?

OpenSUSE Install :: On Dell Server With Cerc Raid

Aug 11, 2011

I want to install opensuse on a poweredge 830 server with a cerc 1.5/6 hardware raid configuration, since i have no previous experience with linux I'm having a hard time to grasp the way to do things. But i would love if someone can direct me to a good tutorial or document where i can learn more. At this moment I'm stuck (though i decided to install using default options yast gave me, just to test) with partitioning and RAID.

So this is what i would like to know:

Conditions:
*Server currently has a windows 2003 installed but I don't need it so actually that is going to go away
*this is a small network, less than 30 users
*Server is going to be used to authentificate users through openldap, also is going to serve files (since we do printing many of them would be 100mb +), and also depending on performance may be used as printing server too (i know that's a lot of tasks but besides printing other functions won't be used that much)
*Server has 2 phisical HD that i want to use with RAID 5 or 6 there are drivers for that already in dell's webpage
* I'm installing openSUSE 11.4

Questions

1.- Does linux really needs a dedicated swap partition
2.- If so how raid works with that, is it going to be mirrored too (I don't think)
3.- Is it better to install linux in 1 HD only with no swap partition, leave the other blank and install raid after linux is up
4.- What's up with ext units, in the sense that now it looks like there are too many units.. not only the simple 'os, data' i'm used to

Objective
1.- I just want to have a linux installation with raid 5 configuration using 2 hd

Ubuntu Servers :: 10.04 Install - On Power Edge 1850 - Start The Partitioning It Hangs Up On 33%

Apr 20, 2011

Im having a bit of an issue installing Ubuntu Server 10.04 on a Dell Power Edge 1850. I am running RAID1 via the onboard PERC4 controller that is set to emulate MASS storage. I am able to boot from the disk and run through the initial setup, however, when I give it the go ahead to start the partitioning it hangs up on 33%. It does this on both the Guided full disk and guided full disk LVM. I have run a check on the disk as well as memory.

CentOS 5 :: Ver5 On Desktop (DEll OptiPlex), Power Cut Oops!?

Sep 10, 2011

I no expert and this was a bit of mucking around. Installed Version 5 dot something on a desktop (DELL OptiPLex) with a couple of extra HDDs, for a server to play with (samba to Windows). I used the drives as a single logical drive via LVM.

We had a power cut, now it doesn't work. In fact it's been hanging around for a couple of years and before I dump it I wonder if there is any chance of getting some of the wife's letters, pictures, etc that I promised I try and get off.

The /boot partition seems to be there and I've attached a photo of what happens at boot, and I admit....I haven't a clue what it all means. Also I did not think ahead and did not create a recovery disk. I know, I know heap damnation on me for being so reckless, but any chance I can get myself back in the wife's good books?

CentOS 5 Hardware :: Connect A RAID Box To The Server Via LSI 8880EM2 RAID Controller

Aug 3, 2010

I 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.

Fedora Servers :: How To Setup A Intel Xenon Power Edge 1900

Aug 31, 2009

I need to setup a Intel Xenon power edge 1900 server, which fedora version (10 or 11) suits it best and whether I should go for 64bit or 32bit (If I go with 64 bit some applications wont support it). I also have another issue, currently on another Intel Xenon power edge 1900 server on which Fedora 9 32bit version is installed, tough the server has 8GB ram, fedora can access only 3.2 GB. How can I solve this issue and will it repeat in the new server where I install fedora(10 or 11).

General :: Dell PE1750 Server Not Boot Up After A Power Failure - FS Check With E2fsck

Apr 19, 2010

I have a dell PE1750 server which would not boot up after a power failure. I am thrown to a shell for maintenance after showing an error in file system check. The server was running - Red Hat Enterprise Linux AS release 3 (Taroon). Please let me know if I can try to recover from this error by booting from the 1st CD of a higher version of linux like RHEL5. I ask this because I do not have the old media with which the system was setup. Can the use of latest OS CD cause any problem?

Fedora Servers :: Setup RAID On DELL Server With F10 64Bit OS?

Jan 22, 2009

I have had no problem installing Fedora OS on any of my Dell servers prior to this post. Anyway, I wouldn't call this a problem but recently, we bought another DELL server with Quad Core, 4GB, etc... AND this model has 2 swappable SAS Harddrives.

I wouldn't call myself an expert but then again I am not a newbie too. However, I have never setup any RAID before and now I am forced to setup RAID1 on this server. So, in a way, I am a newbie in setting up RAID

Would someone please point me in the right direction as I have no idea what I am supposed to do to setup the RAID. FYI, I will be installing Fedora 10 64bit on this server. I would appreciate if you can start from the very beginning, ie. partitioning, formatting the harddrives during OS installation, etc..

Ubuntu Installation :: 10.10 Server (64 Bit) And RAID On Dell Poweredge 2850

Oct 15, 2010

I just got my new server today (a Dell Poweredge 2850), and I'm trying to install the latest version of Ubuntu on it, however it fails to detect my hard drives. They are in a raid array (raid 1 I believe). I've never worked with a raid array before, and I'm wondering, is there anything special I have to do to install Ubuntu on one?

OpenSUSE Install :: 11.2 - Dell SAS / SATA Virtual Disks (RAID 1)

Sep 17, 2010

I have a Dell Studio XPS running openSUSE 11.2 with dual mirrored disks (using Dell's SATA controller). Does anyone know how I can set up automatic monitoring of the disks so that I will be informed if either fail? I think smartd might be what I need here. Is that correct? I added:
/dev/sda -a -d sat -m <my email>
/dev/sda -a -d sat -m <my email>

smartd is running, but how do I know that it will report what I need? I also have a client with a Dell PowderEdge SC440 with SAS 5/iR also running openSUSE 11.2. They also require automatic monitoring. There doesn't seem to be a SAS directive for smartd. I notice that the newer release says it does support SAS disk. I upgraded to 5.39. On restart (with DEVICESCAN as the directive) I get the following in /var/log/messages for my SAS RAID disk.

Sep 18 10:47:26 harmony-server smartd[25234]: Device: /dev/sdb, Bad IEC (SMART) mode page, err=4, skip device
I ran:
smartctl -a /dev/sdb
and got the result:

Is there some other tool/package that does support DELL virtual disks?

Ubuntu Servers :: Dell Powerconnect Sc1425 Won't Detect Raid 1 On Install

Jun 4, 2010

got a dell powerconnect sc1425 running 2 250gb sata drives configured as raid 1 on a CERC onboard raid controller. boot up into 10.04 x64 server install, all goes well until after network discovery it goes to detect hard drives. a message appears "one or more drives containing serial ata raid configurations have been found. do you wish to activate these raid devices?" yes/no whether or not i hit yes or no, the next screen doesnt have any drives listed, just configure iscsi, undo changes to partitions and finish/write changes to disk.so where are these drives? do i have to load drivers like in winblows setup?

CentOS 5 :: CentOS 5 Home Server Power Consumtion? (features, Kernel Versions Etc.)?

Feb 28, 2010

I built a home server (NAS/WWW/SSH/media server etc) and chose CentOS 5 as the OS (stability, easy of configuration).I was just about to start tuning the power consumption when I realised that the kernel CentOS uses is so "old" that it does not support the latest reduced power consumption enhancements that Linux has achieved in big strides in the recent past (we are probably still talking 6-12+ months ago e.g. tickless kernel)..

So my questions; 1) I know CentOS was maybe not meant for home servers (certainly its not its primary purpose), but if it is, any ideas of what kind of power consumption it takes (I know its relative) and if there are particular power consumptions that are worthwhile?

2) Do you recommend me compiling my own 2.6.21+ kernel from kernel.org or am I just likely to have compatibility issues (I really did not want to do that) or when is CentOS 5.4 supposed to have a newer 2.6.21+ version kernel?

Was it wrong of me in principle to choose CentOS for a home server when I am power conscious? (I don't have a low-power VIA processor either but a P4 so I am really just hoping to make do with software changes).

Fedora Installation :: Raid On Dell R210 - Install Driver - Sees 2 Separate Drives?

Jun 4, 2011

Fedora is having trouble identifying a raid partition, it sees them as separate drives. I got drivers from dell, but during a Fedora dvd install, it mentions nothing about a place to install extra drivers.

When it says it must "initialize" the drives, Fedora then breaks the dell bios raid. How to either install the dell drivers or make Fedora see the raid partition as one?

CentOS 5 Server :: Read Only After Power Failure?

Sep 19, 2009

I had a power failure the other day and my server shutdown abruptly. After bringing the server up I noticed that the /var partition came up as read only. I was not able to edit the crontab, not able to write to files within /var/log/ and do other write operations within /var.

I did a mount and it showed that /var was mounted read and write but when trying to run certain operations the system was still saying that it was read only.

CentOS 5 :: Remote Shutdown Server Through Power Switch?

Jul 13, 2009

I have built a Centos 5.3 server for a friend of mine that is being used as a NAS server. The server has 4 1TB drives in a RAID 5 configuration and a dedicated non raid system drive for the OS. My friend isnt very Linux literate so I need this bow to be relatively simple. I have worked most of it out but have a question with regards to remote reboot.

I need to be able to shut this device down through the power switch without human intervention (at the moment when the power switch is pushed the server asks to confirm shutdown) the server wont have a Monitor connected so this isn't practical. Is it possible to use the power switch to do an clean, immediate shutdown?

The other option is shutdown through a web page is this something that has been done before? I know he can do it through terminal by issuing a shutdown now command but as I said this guy wants something simple. I don't really want to explain everytime he needs to shut the Server down how to do it if he can just do it via a website or even with the power button.

CentOS 5 :: Failed To Start The X Server After A Power Failure?

Oct 29, 2010

Before to describe my problem I want to say that I searched a lot on the internet and I think I tried all the solutions provided by other users to similar problems.

I've got an IBM xSeries 346 server running CentOS 5.5 with all updates applied with yum.

The video card is an ATI Radeon (lspci says: 01:06.0 VGA compatible controller: ATI Technologies Inc Radeon RV100 QY [Radeon 7000/VE]).

Everything worked fine until a bad day where there was an environmental power failure and the server crashed.

I turned it on, I manually check the file system, some files went lost and after the reboot the X server didn't start.

After the first boot I had problem with /etc/rc.d/rc.sysinit, sbin/multipath.static and /dev/cpu/microcode, I solved them and now the message it shows is:

"Failed to start the X server (your graphical interface) It is likely that it is not set up correctly. Would you like to view the X server output to diagnose the problem?"

I choose OK and it appears an empty log, if I go in /var/log/gdm and I do an ls -al:

total 0
-rw-r--r-- 1 root root 0 Oct 28 04:44 :0.log.4
-rw-r--r-- 1 root root 0 Oct 28 04:44 :0.log.3
-rw-r--r-- 1 root root 0 Oct 29 04:52 :0.log.2
-rw-r--r-- 1 root root 0 Oct 29 04:52 :0.log.1
-rw-r--r-- 1 root root 0 Oct 29 04:52 :0.log

So a lot of empty log files.

I press enter on the OK that appears at the bottom of the screen and it says: Would you like to try to configure the X server?

I choose Yes, I enter the root password and appears the following messages:

Couldn't start X server on card 0
Couldn't start X server with old config, trying with a fresh configuration

Then another messages:

Trying to restart the X server, I press enter on OK and it loops the initial message ("Failed to start the X server...)

CentOS 5 Hardware :: How To Install CentOS On RAID 5.I

May 10, 2011

I 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 :: Edit Bios - Compaq Evo 5.4 Web Server Fails To Restart From A Power Outage

I have a small problem on my Compaq Evo Centos 5.4 web server. The web server runs just fine, the problem is it fails to restart from a power outage. Simple edit the BIOS. No! For a reason I can't think of the keyboard stops working after a few key strokes following the F10 to enter BIOS setup. Then its a power cycle. If left to BOOT the PC and keyboard are fine. After hearing about viruses which get to the BIOS I will ask can NIX get that far so I can adjust the Power ON?
