Using redhat linux 4 update 5 find out the raid details of a server. I have a machine which is a t remote site. i thing all the disk slots are populated but only two disks are used. I can see those two disks presented as a volume to my operating system. I would like to confirm if the other disks are there or not

View 1 Replies View RelatedI cannot get either sendmail or postfix to send a 220 response, nor respond with details. See below for sample telnet output. Details: I have a server that requires email, but only for light use. I'm definitely not an expert, but I have set up a sendmail configuration on a previous server. I tried to configure sendmail first and then postfix later, when I couldn't get sendmail working. I'm not sure exactly what the problem is, but I have a feeling the following might yield some important information. Note: this is the result for Postfix, but virtually the same thing happened with sendmail, too. That is, initially the telnet connection would close immediately. Afterwords, I could connect a second time but then it never responded with a 220 banner nor any 250's.

How long does hardware Raid card (raid 1, 2 drives)take to mirror a 1 TB drive (500gb used)?Is there a general rule of thumb for this?4 hours? 12 hours? 24 hours?
View 1 Replies View RelatedI 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.
I am looking to convert a raid 1 server I have to raid 10. It is using software raid, currently I have 3 drives in raid 1. Is it possible to boot into centos rescue, stop the raid 1 array. Then create the raid 10 with 4 drives, 3 of which still has the raid 1 metadata, will mdadm be able to figure it out and resync properly keeping my data? or is there a better way to do it?
View 2 Replies View RelatedI have a box that doesn't have a Raid controller or a software raid running currently. I would like to make it a RAID 1. Since it seems there isn't any IDE RAID controllers hardly around, I have another HD that is the exact model as the drive currently in the box running CentOS. Can I some how add the second drive and get the box to mirror from here own out? The box gets really hot and I want to be ready for a HD failure.

Could any RAID gurus kindly assist me on the following RAID-5 issue?I have an mdadm-created RAID5 array consisting of 4 discs. One of the discs was dropping out, so I decided to replace it. Somehow, this went terribly wrong and I succeeded in marking two of the drives as faulty, and the re-adding them as spare.
Now the array is (logically) no longer able to start:
mdadm: Not enough devices to start the array.Degraded and can't create RAID ,auto stop RAID [md1]
I was able to examine the disks though:
Code:
root@127.0.0.1:/etc# mdadm --examine /dev/sdb2
/dev/sdb2:
Magic : a92b4efc
Version : 00.90.00
code....
Code:
mdadm --create --assume-clean --level=5 --raid-devices=4 /dev/sda2 /dev/sdb2 /dev/sdc2 /dev/sdd2
As I don't want to ruin the maybe small chance I have left to rescue my data, I would like to hear the input of this wise community.

View 1 Replies View RelatedHere is my system: I have dell poweredge 1950 PERC 6 with 300 GB raid system. It has two disks of each 300GB RAID mirrored system. I have few applications and data that reached around 280GB. As you know, poweredge 1950 we can have only two disk.
They are not mission critical. Hence, I wanted to remove the raid system and use as a non-raid system. By doing it, The applications and data can grow upto 600GB. I do not want to loose the data and setup. I am not so clear about RAID system and its conversion.
I am running single drive Ubuntu server 9.10 with a lot of software. Now I want to add one more disk (same size and type) and to convert this to RAID 0 without need of reinsallation. Is it possible and if yes how? I didn't find nothing for RAID 0. It sounds simple, but probably is not.

I have a problem configuring a RAID server under Ubuntu 9.10 (kernel 2.6.31.17) with mdadm (v2.6.7.1). First I had some hardware issues that finally got solved by using another motherboard. Now I am dealing with the software part.In order to ease things, I am trying to configure a RAID 5 with three partitions in one disk. I have two HD's, one IDE where the OS lies (recognized as sda), and another where I intend to build the RAID (recognized as sdb). In this second drive I have made three partitions (sdb1, sdb2 & sdb3) of the same size.I've already re-installed Ubuntu 9.10 a couple of times, zeroed the superblocks of the partitions, repartitioned the disks with different partition sizes (I am using 5 GB partitions to save time). I've gone through this process several times, and I really don't know how to move forward now. If RAID is about trust and reliability, this is exactly what I'm not able to get.
View 5 Replies View RelatedI have a new home server I built this weekend with 4 x 320 GB Seagate Barracuda SATA drives. I am going to load my O.S. this week however I don't have a RAID controller so I would like to utilize 'Software RAID' via 'mdadm' package. My question is since this is a general home server with no specific function rather than hold my data reliabily and resonably fast, how do you guys recommend I configure my partitions for RAID? What level would be best with my 4 drive configuration? RAID5 or RAID10? Should I use a 3 drive RAID and use the 4th as a spare? Please let me know what you recommend as I don't have a lot of expertise with what is not practical or useless when it comes to Mdadm RAID.

Like, if you do:
It will give you a list of packets that can be updated, but you don't know to what version and why.
How can I fund out, before updating, what is the version that the new packet will have.
Here I am talking about updates made from the command line.
On a Desktop system, you have that nice list in update manager, and if you click on an item you can see the new version and some details (what will fix, links..)

is there a way to retrieve the processor model without taking information from bios? I don't know which processor is really mounted. I want to set up the right processor timing, but I don't know the processor type. Every time I change the timing for the processor in BIOS another processor type is determined (I should be an Athlon XP +1500, I think, but I don't know really).
I think with less /proc/cpuinfo the results depends on the timing that is set in bios. So could you tell me how I can find out which processor is really mounted?
