Ubuntu Servers :: 10.04 Raid On HP Proliant ML115?
May 17, 2010
I have a problem installing Ubuntu on an HP Proliant ML115. This server has a 1TB mirrored RAID setup (and 1 250GB drive), problem is, Ubuntu apparently doesnt like it, it detects the RAID but fails to partition the hard drives and the installation cant continue. I tried the guided partitioning using the whole disk (detected RAID array). Here is what syslog gives me:
May 17 22:32:30 main-menu[504]: INFO: Menu item 'disk-detect' selected
May 17 22:32:30 net/hw-detect.hotplug: Detected hotpluggable network interface eth0
May 17 22:32:30 net/hw-detect.hotplug: Detected hotpluggable network interface lo
May 17 22:32:31 hw-detect: Loading PCMCIA bridge driver module: i82365
May 17 22:32:31 hw-detect: FATAL: Module i82365 not found.
[Code]...
PS: Im very noob regarding this kind of stuff so detailed instructions please, also feel free to give configuration tips

I'm having a great deal of time getting Lucid Server up and running on my Compaq Proliant ML330 G2. I've put a thread up in installing and upgrading, but people there don't seem to have any ideas about my problem. Since I figured there would be a higher concentration of server users here,
I've got a Proliant ML330 G2, 2 1.4 GHz PIV's
A dvd and CD drive on IDE1 (I'll explain why in a moment
A 65 gb hdd on IDE2
and four 40gb hdd's on hardware ide raid.
I've tried everything, but I can't get the sucker to boot. Installing to the raid array doesn't work. Some array setups won't partition, and others aren't even recognized as arrays. I've tried disabling the raid array and installing to the IDE hdd (my original intention) but I just get bad system disk errors. It would be exceptionally helpful if anyone has one of these boxes, or has worked on one, but I'm willing to take advice from any direction at this point.

how to setup RAID on a Compaq Proliant DL580 G1 Server. Currently there is no OS installed. I used the SmartStart CD but there is no option to setup RAID. When I put in the boot CD for CentOS 5 it recognizes individual hard drives not a RAID Setup.

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.

I forced my workplace to forgo windows and opt for linux for web and mail server. I'm setting up Centos 5.4 on it and I ran into a problem. The server machine is a HP Proliant DL120 G5 (quad core processor, 4GB Ram, two SATA drives, 150GB each attached to the hardware RAID Controller on board). RAID is enabled in the BIOS.I pop in the Centos disk and go through the installation process.
When I get to the stage where I partition my hard drive,it is showing one hard drive, not as traditional sda.but as mapper/ddf1_4035305a86a354a45.I looked around and figured that I need to give Centos the raid drivers. I downloaded it from:
[URL]
I follow the instructions and download the aarahci-1.4.17015-1.rhel5.i686.dd.gz file and unzipped it using gunzip. Then on another nix system, i do this:
dd if=aarahci-1.4.17015-1.rhel5.i686.dd of=/dev/sdb bs=1440k Note that I am using a usb floppy drive, hence the sdb. After that, during centos setup, i type: linux updates dd
It asks me where the driver is located. I tell it and the installation continues in the graphical mode. But I still get mapper/ddf1_4035305a86.a354a45 as my drive. I tried to continue to install centos on it. It was successfull but when i do a "df -h" it gives me /dev/mapper/ddf1_4035305a86......a354a45p1 as /boot
/dev/mapper/ddf1_4035305a86......a354a45p2 as /
/dev/mapper/ddf1_4035305a86......a354a45p3 as /var
/dev/mapper/ddf1_4035305a86......a354a45p4 as /external
/dev/mapper/ddf1_4035305a86......a354a45p5 as /swap
/dev/mapper/ddf1_4035305a86......a354a45p6 as /home
Well i know why it's giving these, because i set it up that way, but i was hoping it would somehow change to the normal /dev/sda, /dev/sdb. That means that the driver i provided did not work. I have another IBM server (5U) with raid scsi drive and it shows the usual /dev/sda. It also has hardware raid. So i know that there is something wrong with the /dev/mapper/ddf1_4035305a86......a354a45p1 format.
First, is there any way that I can put the aarahci-1.4.17015-1.rhel5.i686.dd (floppy image) on a CD?. I really need to set this up with raid. I know i could simply disable raid in bios and then i would get two normal hard drives sda and sdb. But it has to be a raid setup. Any way to slipstream the driver into the centos dvd? The hp link i provided above, under installation instructions, there are some instructions titled "Important". But I couldn't get it to work.

I currently have my ftp server running off of my hp dl360. Ubuntu 9.10 server. I cannot seem to stream anything. I can use WINS and mount the share and then watch videos over my LAN like that but I want to stream my media over the internet, I already have a domain and NAT 100% set up with port forwarding. The snag I am hitting is I cannot seem to get streaming to work over the net.
the stats on the DL360g4p (1u rackmount) are as follows
1x Xeon 3.08GHz - 512MB cache
2 GB RAM
2x 300GB SCSI @ 10k RPM in raid0.
gigabit NIC
ubuntu 9.10 server
All web(http/ssh) traffic is forwarded to seperate ubuntu server VM running ontop of ESXi on a different 2u HP proliant dl380g3. All ftp/smb traffic is forwarded to the 1u dl360. I have tried vlc -I http (port 8080 redirected to ftpserver) under a detatched screen window and it failed to initialize video driver. I have an entire Directory that I would like to make available to stream.

I got my hands on my first real server hardware yesterday - a PIII 600 MHz COMPAQ Proliant 3000 with 1.8 GB RAM, Smart Array 3200 controller and 4x18.2GB SCSI ULTRA 3 hard drives. RAM is upgraded from original and USB card added - otherwise hardware arrangement appears to be original.
Minimal 10.04 installed (35 minutes boot to boot) as Server 10.04 could not detect CD drive. My problem? Everything works but it does not look right. Probably my bigger problem?? I know almost nothing about RAID and the more I read the more ethereal my understanding seems to become.
When installing, I chose to install with LVM on c0d0. Grub written to MBR. I have posted df -l, fdisk -l and lshw output below. Would someone tell me if this looks correct and, possibly, offer some pointers if it does not.

installing Ubuntu 10.04 on a HP Proliant DL180 G6, especially via the LO100 virtual KVM? I can boot almost any linux distro with it, but unfortunately whenever I boot the Ubuntu server cd the screen gets garbled. I did some searching on the net, and found some references to older versions of Ubuntu where one had to add vga=771 to the boot options, but this still doesn't work with 10.04. I tried several vga modes, all to no avail (with vga=normal the screen gets garbled, with anything else the screen just stays black). Anyone got any idea on how to fix this?

I need to install centOS 5.6 64bits in a server HP Proliant DL 165 G7, with four SAS hard disk, a controller array, 32Gb RAM and two processors... I have some experience creating software raid but it's first time i try to install a hardware raid.
For the moment, i began editing the option RAID into the bios and after that create a RAID 10, but now... What steps have i to follow to install centOS? CentOS installer recognize me the raid or have i to install some kind of driver in the beginning to installation process?
note: I found some diskettes from HP, but im not sure if that works to me: [URL]

I've installed Ubuntu Server 11.04 64-bit on an HP Proliant Microserver. The install seems fine but I'm having a start-up problem. When I boot the server, I get a blank screen after the Grub Menu. If I press ALT-F2 I get the login prompt. I've tried editing the grub file (after having done some googling) and tried adding nomodeset to the following line in the grub file:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset acpi_osi=Linux"
I added nomodeset as well as acpi_osi=Linux to see if that would do somethng. After adding nomodeset, when I boot the server, I still get a blank screen after the Grub menu but this time a blinking cursor. Again, if I press ALT-F2 the login prompt shows up. So it boots (I'm able to putty/Webmin in even when the screen is blank) but don't know why I need to press ALT-F2 all the time to get the login prompt to appear. Plus I don't see the boot process right before the login as well.
HP Proliant has the following chipset and processor:
- AMD RS785E - north bridge, core logic controller
- AMD SB820M - south bridge
- AMD Athlon II NEO Processor 1.3 GHz Dual Core
I've also tried adding xforcevesa instead of nomodeset and that option too leaves me with a blank screen.

I have a Compaq server, as per the title, and I wish to install Ubuntu Server onto it but ran aground when I found it got to trying to run the installer after the CD Boot menu, it just stopped there, waited 180 seconds (as per the error's details) and then locked up with the Caps Lock & Scroll Lock lights on the keyboard flashing.
Now I know it's not the server, as I have installed other OSes onto it in the past, including an older version of Ubuntu server (9.04), I did try and re-install the 9.04 version but the CD I had was too scratched up and got to a point in the installer (copying files) where it just failed cos it couldn't read the disc.
The specs of the thing are:
Dual PentiumIIIs 1.4GHz
512mb RAM (keep meaning to upgrade it)
3x 18.2GB 10k SCSI HDDs (Storage)
[code]...
Not sure what else is in there, but the full specs are on the web...

I acquired an old ML370 Proliant server, and I'm attempting to find a way to control the fan speed, as all three noisy fans are running at full blast, and I had planned to keep this thing in the office, because it has no wireless capability or support.
I know the following:HP has a suite of programs that are variously called Insight Control Manager, Server Health driver, HP-health, hpasm, and a few more I can't remember. Obviously these are different iterations of the same program, but I have been unable to determine which one I need, and I've been completely unable to find a way to install any of them or find the repository that contains them.
The website: Download Drivers and SoftwareIt lists a lot of different Enterprise-class Server OSes, but nothing about Ubuntu or any home server OSes. I've only been at this for a week, so I don't know which of these would work with Ubuntu Server, or how to make them work if their aptitude file extension is not .deb. I'm currently running Server version 10.10, as 11.04 gave me monitor troubles.

I'm trying to get the HP Proliant DL120 G6 server a lot quieter after startup under Ubuntu Server 11.04 (x64).
For now, it seems like there is no fan control at all: when I start the server, the fans start running at max speed, then it slightly lowers to 3.5K-5K RPM. Once there, it never goes down or up. There's just no fan or power control at all.
In no specific order, I will describe as much as I can my situation.
The system is IPMI 2.0 compliant, so when using the ipmitool package I can get the values of the sensors like this:
Code:
I tried to follow the procedures for using the fancontrol package together with lm-sensors, as shown at [url]. One of the very first steps is to launch "sensors-detect", which gives:

I'm wondering if I could put my old DualCore PCIe Board into a Proliant 3000? Why not; I mean, the Array Controller should plug right into the PCI slot on the DualCore board. Of course, I'll have to shoehorn a second power supply into the case for the newer Board, but wouldn't it be a monster! Two 3GHZ Processors, with a 256 MB nVidia graphics card, 1.5 GB of RAM, and 8 Hard Drives! (7, actually, because one of them doesn't work). I'm up late, and I think I'll start working on it right now.

I have an ML570 G4 with a P400 array card. Ubuntu server 10.04. I added more drives and extended the size of the partition to 2048gb. Now on boot I get Grub Error 18. The live cd sees the partition I just cannot boot it. I've googled around quit a bit,but have not found much that is relevant. I believe I am going to be adding a smaller boot partition to the beginning of the drive to fix this

I have two drive on my Ubuntu server. I have a 40GB IDE 5400RPM and an 80GB SATA 7200RPM.
Is it at all possible to RAID 0 the two of these drive? I know it's pretty unorthodox, but it's what I've got without having to buy anything.
If so, what are the limits, cons, and/or potential pros of doing a RAID of these two?

I am attempting to run Ubuntu 10.04 Server on RAID 1 and am consistently hitting the same issue when trying to boot the system for the first time (after what seems to be a successful install of the OS). I am creating the RAID 1 using the directions found in the Ubuntu Server Guide. The error I receive when trying to boot the system for the first time is...
Code:

I've had this server for a while and I've periodically received similar errors, but it's been worse lately. I'm trying to diagnose and similar posts have left me with 2, maybe 3, ideas about what could be wrong. Here is the setup: Ubuntu Server 10.10 maverick kernel 2.6.35-30-server Sans Digital TR8 8 bay raid - 2 port multipliers to esata outputs 8 1TB WD Caviar Black Syba PCI-e card with Sil3124 chipset - 2 external esata inputs I do not use the RocketRaid 622 card that came w/the enclosure because I had problems with drivers and configuration so I went with the SI chipset. The raid is configured with mdadm, level 10, running ext3 file system:
Code:
root@i5server:~# cat /proc/mdstat
Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10]
md0 : active raid10 sdb1[5] sdg1[2] sdd1[7] sdh1[3] sdf1[1] sde1[0] sdc1[6] sda1[4]
3906721792 blocks 256K chunks 2 far-copies [8/8] [UUUUUUUU]
[Code].....
What's odd is that the raid dropped out and completely locked up the computer multiple times, then marked one of the drives as failed. I did a readd on the drive and it rebuilt witout issue. Ran e2fsck -f to clean up the problems it had when it crashed, but as soon as I do heavy read/writes the errors start showing up again. This is primarily a media server for music and movies, but also for backups and printing. Heavy read/writes are generally transcoding movies and music which is what I was doing when it failed.

I'm having a problem with the installation of Ubuntu Server 10.04 64bit on my IBM xSeries 346 Type 8840. During the installation the system won't recognize any disk, so it's asking which driver it should use for the RAID controller. There's a list of options, but nothing seems to work. I've been searching the IBM website for an appropriate driver, but there is no Ubuntu version (there is Red Hat, SUSE, etc). I was thinking about downloading the correct driver onto a floppy disk to finalize the installation, but apparently no 'general' Linux driver to solve the problem here.

I've recently completed a fresh install of 10.04 on a home file server and upgraded the hard drives in my storage array. My PREVIOUS hardware was:
Old version of Ubuntu (I forget which one exactly, but I know I had missed a few upgrade cycles)
3X 500 GB Seagate Baracuda's (for the array)
Areca 1220 Hardware RAID controller
Intel Core 2 Duo 6600
320 GB Seagate for the boot drive
I was running that hardware for about five years or so and it was rock solid. After the upgrade the hardware specs are:
Ubuntu 10.04
Areca 1220 hardware RAID controller
4x 1000GB Samsung
Intel Core 2 Duo 6600
320 GB Seagate for the boot drive.
The fresh install of Ubuntu 10.04 went remarkably well. The drivers for that raid controller are in the kernel, which is great. I was able to access the old array after upgrading Ubuntu. Now I am trying to create a new array with the four 1000 GB drives in a RAID 5. Obviously that gives a maximum storage capacity of 3 TB, greater than the 2 TB threshold that seems to be so important. I've been doing some digging and here is where my questions start:
it appears as though gparted doesn't support file partitions greater than 2 TB, correct?
it also doesn't seem as though parted supports ext3 or ext4, is that correct?
If this is the case, how do I create a partition with ext4 that is greater than 2 TB?
I can see the array volume in gparted (which is a relief) but it lists the size as 2.73 TiB, which I find curious because that is over 2 TB, but not the full capacity of the volume. I can also get to the volume in parted. But I see in the parted documentation that using the makepartfs command is discouraged and instead, one should use the command mkpart to create an empty partition, and then use external tools like mke2fs ( to create the filesystem.
how to proceed from here. What does the community think is the best course of action to create a partition of 3TB in ext4? Then I need to change fdisk to automatically mount the array at every log in, right?

I'm setting up a web server but I have no experience with RAID. I would like to try this configuration if possible:
2 x HDD 500GB RAID1
1 x HDD 20GB (logs and tmp)
The old 20GB drive I would like to use it to store logs and temporally files (mounted in /var/log and /tmp respectively). With this I'm trying to reduce some disk usage in the RAID drives. In my idea, it would be better to write the access/error logs of the web server in a separated drive to the one serving the files which may increase speed... sounds crazy?
One problem is that during the installation, If I set the RAID automatically it will try to use my 20GB HDD as well in the RAID... Does it will work if I set the RAID first (removing the 20GB HDD) and then set the mount points in it after the installation?

I'm in the process of setting up my very first ubuntu server.
Using 10.04 and has 2gb ram
I am using Ubuntu's software raid (mdadm)
It will be a file server, with 4 hard drives (3 in RAID5 and 1 as a spare)
All 4 drives have 2 partitions:
Partition 1 - 100mb
Partition 2 - The remaining drive space
I setup the first 3 drives' partition 1's to be RAID1 with the 4th drive's partition 1 as a spare. This is where I'm mounting "/boot" (it's my understanding that /boot cannot be on a RAID5). I setup the first 3 drives' partition 2's to be RAID5 with the 4th drive's partition 2 as a spare. This its where I'm mounting. I believe so far I'm setup correctly to be able to deal with a drive failure and the system should operate just fine. What I don't know what to do is with the /swap. I want to retain the ability to be able to operate with a drive going down. But I have also read warnings about putting /swap on a raid. How would you setup /swap?

I am trying to build a storage server using software RAID. After getting writing RAID information to what I thought was the drives, I realized the configuration was not going to work. Since that time I have modified the RAID configuration more than once plus this is a project that was started a few months back. Between the time delays and currently written configuration, things are a confusing mess.
What I would like to do is wipe out all software RAID and start all over again. The problem is that I am unable to figure out how to get rid of it. I used DBAN to wipe out all four of my 1 TB drives which took a while. But still, the RAID configuration pulls up when I try to do a new install. Where is the RAID configuration data stored at if not on the HD? How can I scrub that information off so I can start all over again?

The OS drive is 250gb which I know is more than enough, but it was what I had free at the time. I added 3 1tb drives to the computer, but not sure how to create a raid with them. I've done some searching, but still haven't been able to get it done successfully.

I have an Areca hardware RAID array that I'm trying to format & partition on a fresh Ubuntu 10.04 LTS installation. The OS drive is not on the RAID card, it's entirely separate. The RAID is a 6TB volume so I realize I have to use parted to format it, not fdisk (which I've always relied on).
My problem is that I can't figure out how to get parted to like my settings. It seems like everything I try gives me the warning "Warning: The resulting partition is not properly aligned for best performance." Here's what I'm doing:
Code:
(parted) p
Model: Areca ARC-1280-VOL#00 (scsi)[code].....
What start/end settings should I use to get a properly aligned partition? How do I know?I have tried a mix and match of 0, 0s, 1, 1s, -0, -0s, -1, -1s, 100% for my start/end with no success.

I am trying to grow my array to make full use of my drives. I have a raid 6 using mdadm on my home server. The array used to consist of 6 1.5TB drives when it was created. Since then I've been replacing the 1.5TB drives with new 2TB drives. And now I have replaced the last 2 drives.
When I added the first 3 disks I did not use the whole disk for the raid partition but rather made it the same size as the 1.5 partitions. As it turns out this may have been a bad idea. (But it gave me another 3 partitions of 500GB that I turned into 1 disk using mhddfs.)
Now I'm trying to grow the array. I've been testing in a virtual enviroment on how to do it but I cannot find another method than this :
1) fail 1 disk.
2) re-partition the disk with the size of the whole disk.
3) re-add the drive as a spare.
4) start the now degraded array to let it resync.
5) wait quite a while. (aprox 5 hours)
6) start again from step 1 for the other disks.
7) use mdadm with grow command to enlarge the array
use resize2fs to fill array to max size
Now although since this is a raid 6, I keep some redundancy but I still worry about degrading the array so manny times and rebuilding the whole thing. I mean I read the thing out 3 or 4 times over doing this.

I've been running my dedicated server on Ubuntu 10.04 for 300 days non-stop so far (touch wood). I'm planning to purchase a dedicated server to host many large sites. The specs are Sandybridge Xeon with 16 bay x 2TB storage using RAID5 (Adaptec RAID 51645).I don't have experience with RAID, but I read that ext4 can only support filesystem up to 16TB, my plan for the system is to have 32TB of storage. How can I make Ubuntu run this configuration?
Also, can Ubuntu 10.04 recognize the Adaptec card? Going through Adaptec website there is no mention of drivers for Ubuntu (although many other distros are available).
