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.

CentOS 5 Server :: Configure A Mail Server Over A Home Internet Connection?

Feb 12, 2009

I have one server at home, connected through a router that gives me a static IP:192.168.1.2 - My PC192.168.1.3 - CentOS serverI enabled the port 80 into router forwarding system and I can connect properly to CentOS server, using the IP my internet provider gives me. My router automatically forwards a changed IP to my dyndns.com account so I can also access the server through a domain name (I pay to have it linked to one of my domains).My next step is to configure the mail server (dovecot) , so I can send emails from my local server(192.168.1.3).I was wondering if anyone has any tutorial links or tips to have the mail server configured through a home internet provider + home router.

CentOS 5 Server :: Possible To Create RAID SW On Working System

Oct 5, 2009

I'm working in a little company and 2 weeks ago one of our server had a hard disk failure (yes it was a seagate 11) and after passed two days without sleep trying to recover everything (and we did it!!) we took the decision now to use in some of our server a raid sw, so if one HD fail we can continue with our system without losing nothing. Yes I know normally you have to take all the precautions before so this things never happen, but you know I thing if it never arrives you, you always think than you're lucky and it's never going to happen to you but one day you discover reality.

So now this server is working with a Centos and the default HD partitions one boot partition and the LVM. I'm reading everything I'm finding about raid sw and lvm but I don't find if it's possible to create now with the system working a raid sw without having to reinstall all the system. Is it possible to do it ? If not what are my options to make a system backup before reinstalling everything?

CentOS 5 Hardware :: Mounting RAID Array On Samba Server?

Jun 23, 2009

I need to mount my raid array on CentOS 5.2 samba server.

Here are my hardware specs:
Motherboard: Tyan S2510 LE dual PIII
CPU's: Intel PIII 850ghz socket 370
Memory: 4 gig Crucial 133 ECC SDRAM
OS: 2 x'x IBM Travelstar 6.4 gig 2.5 hard drives, (low heat/noise)
Storage: 4 x's Seagate 500 gig IDE 7200 rpm
RAID controller: 3Ware 7500-12 controller, (RAID 5) (66 mhz PCI bus)
NIC: 3COM 3C996B-T gigabit NIC, (66 mhz PCI bus)

I have the 2 IBM's set as RAID 1, (mirror) and the 4 Seagates as RAID 5, (1.5 TB) I have installed the OS with minor problems, (motherboard doesn't like the 2.6.18-128.1.14.el5 kernel, removed it from my grub.conf).

My problem is mounting the RAID array. I have done the following:
formatted with fdisk;
fdisk /dev/sdb
Then formatted with the following command;
mkfs.ext3 -m 0 /dev/sdb

The hard drive was formatted with the ext3 files system, but I have mounted it as an ext2 file system as I don't want 'journaling' to occur. I then edited my /ect/fstab like this: .....

Then: mount -a
When I go into my "home" directory and type ls, I get the following:
[root@hydra home]# ls -l
total 24
drwx------ 2 zog zog 4096 Jun 23 15:50 zog
lrwxrwxrwx 1 root root 6 Jun 23 15:46 home -> /home/
drwxrwxrwx 2 root root 16384 Jun 23 15:34 lost+found
drwxr-xr-x 2 root root 4096 Jun 23 17:18 tmp
Why my home directory is showing under home?

CentOS 5 Server :: Best Practises For Managing Software Raid Arrays?

Jun 10, 2011

With mdadm was only able to add a new drive to the using the --force function. I do not feel comfortable with using the function that way though.

When I remove a disk in VMWare, it perfectly says that the drive is lost and the array is degraded (mdadm --detail /dev/md0). Although after re-adding the drive, it immediately shows device as busy for both mdadm and sfdisk when I don't use --force.

Recovery and repairation of degraded array worked fine with sfdisk --force, mdadm --add --force, it automatically started recovering and took not so long.

What are best practises to manage software raid-1 arrays?

I've been reading some forum and even centos document regarding establish networking but it seem difficult for me to understand all the terms and jargon overnight.I also have been try to configure the 2 nic using the "trial and errors" approach but no luck..i'm really hoping that someone could guide me so that i could configure the 2 nic correctly hence my centosbox could be more beneficial..below is the scheme how my network will be..internet------>modem--------->centosbox--------->switches------->computers(eth0)(eth1
