CentOS 5 Hardware :: 5.5 On An Intel S5500BC Board With RAID1?
Nov 23, 2010
I'm trying to load CentOS 5.5 on a new server with an Intel S5500BC motherboard using RAID 1. This board has a known problem with RHEL 5.x and the driver disk supplied has a fix. Here is the download for the driver [URL] Under the ESRT2_RHEL4-5_SLES9-1--11_v.13.21.2010_README file are directions in Section 3.1.3 on how to install the RHEL5x megasr driver. This works. The last thing replaces the ACHI driver with the megasr driver (paragraph 15) by loading the megasr.13.21.0614.2010-1-rhel50-u4-all.img in a temp file and then type "./replace_achi.sh". This step doesn't work and it is the critical one as it replaces the achi with megasr in the initrd image.
2xHDD 300GB RAID1 - OS part 2xHDD 1TB RAID1 - data part. Both arrays were created inside the bios-like setup.
During the installation of fedora I "checkboxed" only the 300GB OS raid and used it for the installation. Everything is ok with it. After installation finished and I rebooted, I tried to initialize my second RAID1, that's 1TB - I was able, it was OK, I created 1 max-size filesystem there and put some data in it. After reboot this filesystem didn't want to mount for some reason - so I commented it in fstab and to my surprise, when I reached linux - the partition for it doesn't exist!!! Here is some data:
My guess would be that I am not fully and properly initializing the second array, (it's marked as auto read only in cat /proc/mdstat) but I'm not sure how to proceed.
I have installed Fedora 14 on Intel's DH67BL mother board, which has a on board LAN port, Fedora 14 does not detect on-board LAN. Unfortunately, intel does not provide any driver support for linux OS :-(. However, if I install an additional LAN card, Fedora 14 detects it and everything works fine.
I have installed slacware 13 on an intel server, but the IP add that i have assigned does not work. I used ifconfig to check the ip but it shows me 127.0.0.1. I have run netconfig with the ip address i need and restart the machine, but it goes back to 127.0.0.1
I have a Intel server board machine that has a on board Matrox cardWith 11.2 the install barfs to text mode configuring the card during install butonce you log in a root and run sax2 it is OK once the machine restartsWith 11.3 it installs ( apparently ) perfectly then just goes to a blackscreen .. the usb keyboard is dead and that is that
I was just given a computer from a coworker and installed the latest Slackware version on it. I then installed Gnome Slackbuild and installed the Nvidia driver.I've run alsaconf and it seems to run fine without any errors and unmuted all the channels in alsamixer.
I have an Intel server, which has it's two SATA HDD's in "Intel Embedded Server RAID Technology 5.4" RAID1 volume. How to proceed with a system image in case two of those SATA HDD's fail at the same time? Should one take the first HDD of RAID1 volume, connect it to another machine and execute:
Code:
# ddrescue /dev/sda1 /media/External/image_of_first_hdd /media/External/log_of_first_hdd * HDD from the problematic RAID1 volume would be recognised as /dev/sda1 behind new machine * /media/External/ is a mount point for large external HDD in the new machine * log_of_first_hdd would be the log file
..and then take the second HDD to another machine and execute:
I am using CentOS 5.2. I am installing from disc on a machine with Intel Embedded Server Raid Technology. It has two 500 GB SATA drives. During the initial boot process, it sees that these two devices exist. However, after getting into the screen to partition and configure RAID, it just shows this:
Drive /dev/mapper/ddf1_MegaSR R! #0 (475879 MB) (Model: Linux device-mapper)
I want to do a RAID1 so that the disks are mirrored. However, I would expect to see both drives listed. I can select RAID to create RAID partitions, but I think I need to be able to see both drives in order to do this correctly.
Today I made a samba-share out of /Video/Rorschach to easily put files in there from my windows7-machine (the plan is to steam from my CentOS-server to my HTPC which hasn't arrived yet).I started to put movies in there. It went just fine for a while but then I got this message:

How is that even possible when df -h looks like this?:
[root@Rorschach Rorschach]# df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/VolGroup00-LogVol00 446G 70G 354G 17% /
I'm new to Centos and very new to RAID/hd setup. I have a old HP proliant G3 ML150. I have no drivers cd or other, only the server. I have created a RAID1 array (named SYSTEM) with 2 HD of 250GB from the controller and have installed Centos 5.2 (updated after to 5.6). The installation is ok. Now I have added 2 HD of 1TB each and have created another RAID1 array (named DATI) from the controller. This RAID is to store data files. (And next I have to add another RAID1 for backup, but this is to do next week). how can I format and add it to Centos so I can use it?
I have software RAID 1 on two physical discs. There are now 4 md -partitions (md0 ... md3), which are used in such as / and /home among others. Now current size of /home (md3) is starting to be full, and since / (md1) has more than plenty of free space I decided to fix the situation by shrinking / (md1) partition to free 40 Gigs of space and then growing /home (md3) partition for that 40 Gigs.
I already checked for some info using mdadm and got the following:
Now I would need some support on HOW exactly should I do this resizing since it is on RAID partitions.
Would it be good to use resize2fs to modify the filesystem sizes and mdadm to configure the partition sizes. Or could I perhaps get over this even easier by using GPartED (in case it supports my RAID)? Has anyone here done similar resizing on software RAID1 partitions?
The motherboard currently installed on my PC has a RAID Utility (Ctrl+I) at the startup that allow creating RAID1. But I already have a system installed with CentOS 5.4. In order to protect my data, I need RAID1. Can I add another Hard Drive now and have the data mirrored and synced onto both hard drives as if it was in RAID1 right from the beginning?
Not sure on what is going on here. The server is RAID1 through hardware RAID. It was running an unusual high load so I rebooted it. Now it won't boot up. I am getting these errors after the CentOS boot screen:sda: Current [descriptor]: sense key: Medium ErrorAdd.Sense: Address mark not found for data field
end_request: I/O error, dev sda, sector 3040555357 device-mapper: raid1: A read failure occurred on a mirror device. device-mapper: raid1: All sides of mirror have failed.
OS Version: CentOS 5.3 Motherboard: ASUS M3A78-CM (BIOS v.2003)
I have a single disk running the base OS and just installed 2 x Seagate 500GB SATA 3.0 drives in a RAID1 set that I would like to use for data storage. The OS sees the drives individually but not the RAID. Has anyone worked with a similar board and has any ideas what I need to do to get the OS to recognize the RAID1 array?
and I verify that /dev/md2 and /dev/md3 exist. But if I reboot the computer, these two devices are gone. I'm sure I am overlooking a step but I can't seem to find what it is. Could someone tell me what I need to do next?
I installed a distro based on CentOS 5.5 (FreePBX distro FYI). It used an automated kickstart script to create an md RAID1 array of all the hard drives connected to the machine. Well, I installed from a thumb drive, which the script in interpreted as a hard drive and thus included in the array. So, I ended up with three md arrays (boot, swap, data) that included the thumb drive. Even better, it used the thumb drive for grub boot so I couldn't start up without it. I was able to mark the USB drive as 'failed' and remove from each array, and even change grub around to boot without the usb drive, but now each of the arrays is marked as degraded:
I've just set up a PC with CentOS 5.3 runing on near identical hardware to an existing 5.2 machine. Motherboard is Asus M2A-VM which I discover by chance generally works very well with CentOS. Ethernet is on board Nvidia.The older machine just did run gigabit speed without any intervention at all, rather to my surprise. The newer machine insists on running at 100 Mbit which is annoying as it is connected to a NAS through a gigabit dumb switch.
The obvious difference between the two is that ethtool on the older machine says that supported ports are TP, and so the port is TP. Whereas the newer machine says that supported ports are TP or MII and insists on running MII. I cannot change this with ethtool -s eth0 port tp. Perhaps not too surprisingly, mii-tool says that the supported speeds range up to 100 Mbit.
I have a Biostar TA785GE which as I understand it, has a Realtek 8111DL on-board.
Booting with the default label from the 64-bit installation DVD crashes before any user input, with indecipherable text on-screen (text mode, not X11). Symptoms were the same with the Fedora 11 32-bit installation DVD and the Fedora 12 Live 32-bit CD. Booting with "linux text" mode shows a kernel panic in ":r8169:rtl8169_init_one+0x369/0x9d4" from "pci_device_probe+0x100/0x180".
Disabling the on-board NIC allowed the boot to proceed, and get as far as detecting the hard drive partitions (where I stopped it since Ubuntu is installed).
Ubuntu 9.04 Workstation(Desktop?) install DVD worked fine, and I've installed it and am using it to enter this. From Ubuntu 9.04 on this hardware:

I 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.
I've got a mailserver set up in a raid1 array.I shut down the system to install a CD-ROM drive but forgot to change the master/slave settings (I know, don'tt say anything) and didn't realize it before Centos started booting up, so it booted the hdc drive from the array.I rebuilt the array using mdadm without any apparant issues but on subsequent bootup, I get the following error :
There doesn't seem to be any side effects to this but since that didn't happen prior, I figure there's probably something I didn't do properly since I'm fairly new to the linux world.My raid array was originally set up by the Centos instal software and is set up like this :
hda1 + hdc1 = md0 (boot) Hda3 + hdc3 = md2 (/)
The other partitions are of the same size on each drive and are swap partitions.
PS : The drive is SMART capable and no errors appear during a self-test.
edit : Clonezilla also fails to boot properly although I don't know if its due to a software raid array in the first place or the errors in the filesystem. When only one drive was detected because of the jumpers, it booted properly.
I have installed a 2TB drive in my dual PIII 866 with 750MB ram. The drive is properly installed and I have configured the drive with 1 partition in RAID1. The array loads fine, but when I add the entry to mount the /dev/md2 /data/repository the following error occurs The filesystem size according to the superblock is 488378000 blocks The physical size of the device is 488377986 blocks Either the superblock or partition table is likely corrupt I have run fsck manually with no errors reported. I have removed the partition and rebuilt the array. The array assembles properly and I can manually mount the /dev/md2, but as soon as I add the entry to the fstab I get dropped to a shell after a reboot. Not sure where to go now?
Everything has been working fine but I recently installed a sata drive and lvm didn't see it. I'm sure its a driver issue. I'm running centos 5 on a Tyan-Thunder-K8SR-S2881 board. currently centos is running on an IDE drive. I tried several drivers for red hat distos 3 & 4 but no success for my sata drives to work.
I can not get any output from the digital optical S/PDIF jack on my on-board audio device. But I am getting an analog signal from the headphone jack. I don't have an RCA S/PDIF cable, so I haven't tested the RCA S/PDIF jack. Below are my system specs and hardware info.
According to my MOBO (DFI Blood-Iron P45) manual, the Audio device is: Realtek ALC885 HDA CODEC 8-channel audio output Optical S/PDIF-out and coaxial RCA S/PDIF interfaces
There are 6 phone jacks (including 1 mic), an RCA S/PDIF, and an Optical S/PDIF jack on the MOBO. The output of alsa-info.sh is here:[URL]... Note that I tried several model options (6stack-dig, 6stack-dig-demo, intel-alc889a, auto) for the snd-hda-intel module, but none worked,
I have installed CentOS. I have two ethernet card (one onboard and one PCI). I am able to set ip for realtek ethernet card and my atheros(on board) is not shown in network ifconfig shows only one ethernet card (PCI) hen i gave the command lspci i got the following output
I have 2 WD20EARS hard drives on the way (2 TB green WD disks with 4k sectors) and I'll be installing Centos 5.5 in RAID1 on them (2 partitions, one 16 GB / at the beginning and the rest in its own partition). I read the following thread: [URL]
and it seems that I might be having problems with the 4k sectors (Advanced Drive Format in WD lingo). I'm confused as to what exactly to do. I was thinking of downloading Fedora 14 Live CD and partitioning there and then switching to Centos 5.5 to install. Will that work? Seems I want the md 0.9 metadata because it doesn't have the space limit for me (2 TB) and it's stored at the end of the partition so it avoids alignment issues. Will I be able to make that happen with Fedora 14?
I've faced the problem with server freeze on heavy write.
