CentOS 5 :: Poweredge 6450: No Drives Showing On Setup?
Apr 4, 2009
I want to change one of our poweredge 6450 servers over to Linux, specifically CentOS, however, I cannot seem to install the operating system. When I boot to setup, go through the first couple of pages and then go to the page that asks you where to install CentOS, no drives are shown in the list, and I can't continue. I'm guessing there are missing drivers for the SCSI controller or something along that lines, but I'm not sure, and I can't find any answers on Google either.

I am attempting to install CentOS 5 on a Dell poweredge 6400. The drives are configure for Raid 5 with about 67 gigs of space on the server. When I select any option under Partitioning of your hard drive, it gives me an error. " No Drives found - An error has occured - no valid devices were found on which to create new file systems. Please check your hardware for the cause of this problem."

I tore down my old ftp server running FreeNAS because it had some issues. I decided to add a couple more drives and install CentOS on it instead. So now I have 4x 2TB drives that I set up yesterday.OS is installed on a usb flash drive exclusively while I chose to set up the 2TB drives in two stripes and then mirrored, for RAID0+1 instead of RAID1+0.
/dev/md0 = drive 1+2 in RAID0
/dev/md1 = drive 3+4 in RAID0
/dev/md2 = md0+md1 in RAID1
Well, the sync time for these two mirrors of blank drives is almost done, having taken some 15+ hours.I chose this setup to have a single 3.6TB file system mirrored to another 3.6TB for "backup". As this is only going to be a headless ftp server, I don't need massive redundancy/backup. A mirror should suffice if I need to pull some files.So now I'm second guessing myself. I'm wondering if it is even worth it to stripe 2 drives into a single volume with such large sync times. Since data xfer will be over internet, I don't require the massive file writing capacity that would be preferable if it were in my home as a NAS. So, the "performance" increase of RAID0 is not strictly mandatory.
I'm wondering if I should just wipe the drives and set them up in JBOD or LVM instead of RAID0 arrays.In case of boot drive failure, I'd be booting a livecd to xfer files elsewhere or recover the boot drive. So, what difference would I see if I were livebooting to md0, md1, md2 for data viewing as opposed to livebooting to an LVM or JBOD array?As an aside, the drives are WD20EARS, which are 4k sectors which I aligned to start at sector 2048 in fdisk.

I am trying to install CentOS 5.5 on a older Dell PowerEdge 2450. Is there any reason the install would fail? It does load the initial install screen but when I hit enter, it simply goes to a blank screen with a blinking cursor ( I want to say that it says to me "What are you doing Dave?"), but I won't. It just sits there on this screen.

I have two Dell PowerEdge 2650 servers. One is a dual Xeon 3GHz with 4GB of RAM (4 x 1GB sticks). The other is a single Xeon 2.4GHz with 3GB of RAM (2 x 512MB and 2 x 1Gb sticks).
Both are running 32 bit CentOS 5.3. Both are running the same kernel (vmlinuz-2.6.18-164.el5). I've even diff'ed the two kernels to ensure that they are in fact identical. The only parameters being passed to the kernel via the grub config are "ro root=/dev/sda2"
The BIOS shows 4GB detected on the 4GB server and 3Gb detected on the 3GB server on boot.
Dell OpenManage for the 4GB server shows "Total Installed Capacity 4096 MB, Available to the OS 3804 MB", as I would expect. However, OpenManage for the 3GB server shows "Total Installed Capacity 3072 MB, Available to the OS 1011 MB". (i.e. it is only seeing the first 1Gb of memory).
cat /proc/meminfo confirms the above; the 4GB server shows "MemTotal: 3895980 kB", but the 3GB server shows "MemTotal: 1035024 kB"
I installed the lshw utility, and on the 3GB server it shows all 4 memory sticks, the full 3GB:
*-memory

physical id: 1000
slot: System board or motherboard

I am having issues installing Centos on a Dell Poweredge 1950. I have tried 5.3 and 5.4, and the text only install. The error I get is when I select what keyboard layout to use. An error window pops up and says "Assertion ((C * heads + H) * sector + S == A) at dos.c:624 in function probe_partition_for_geom() failed " I can click ignore and cancel but it instantly pops back up. I have tried to look up the error but can't find any information on it.

I'm running a Poweredge 4400 with a 3com card and an intel card covered under e100.
I'm using centos 5.5 in its default server config coming from gentoo.
I have no link on either of the two interfaces, ever. The card initialises with ADDRCONF(NETDEV_UP): eth0: link is not ready and then falls back to half duplex but still with no connection.
I have manipulated most of the general settings that can be changed with ethtool.
Set to manual configuration with 100/full duplex
The cards are recognized alone and together. I have setup static interfaces with no problems. The ping to the local interface such that:
nic = 192.168.1.10
ping 192.168.1.10
we get back route times and all is well
ping 192.168.1.1
no route...
I have tried several different cables verified good other connections. I have verified the ports I am connecting to work correctly. I have manually shut down the onboard nic (in bios) and tried the 3com card alone. I have tried pci=routeirq, thinking there might be an irq issue.
If this was just the one card, I would install another and move on, but both nics are acting in exactly the same way.

I have a Dell PowerEdge 1950 with Centos 5.4 installed. I am having an issue where there is no network activity on any of the NIC's.(Broadcom and Intel).
I have read that this might be somewhat common but have not found any solutions. I am unable to ping anything internal or external. Has anyone encountered this problem and have a potential fix?

we have 22 servers Dell (20 Poweredge R210 + 2 Poweredge R310) with CentOS 5.5 x86_64 (kernel 2.6.18-194.26.1.el5). Half of these are on different rack. During the day, some server reboot without any reason and the messages log file had no evidence of what happened.
From /var/log/messages:
...
Dec 8 14:10:02 hadoop011 snmpd[3029]: Received SNMP packet(s) from UDP: [172.27.1.21]:50825
Dec 8 14:10:02 hadoop011 snmpd[3029]: Connection from UDP: [172.27.1.21]:50825
Dec 8 14:15:26 hadoop011 syslogd 1.4.1: restart.
[Code].....
Some minutes after the reboot, messages log this error: Dec 8 14:18:14 hadoop011 Server Administrator: Instrumentation Service EventID: 1404 Memory device status is critical Memory device location: DIMM_A3 Possible memory module event cause:Multi bit error encountered.
Is it possible that 20% (circa) of 60 memory bank are broken? By the way, memory bank have Lifetime warranty from Kingston. If I reboot again the server affected by this error, the error disappear from messages log file and from OpenManage Web interface.
Is it possible that is a CentOS bug? I had search some relative bugs on Bugzilla but without any results.

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?

I upgraded to Ubuntu 11.04 from 10.10 about a week or so ago and since the upgrade when I boot into Ubuntu (I am running a dual boot Ubuntu and win7) other HDD's and partitions often do not show up anywhere on my system. For example I have an ntfs partition that I store music on so I can access it on either windows or ubuntu, as well as other partitions. When this issue occurs even my dvd drive appears not to exist. I have to reboot my machine sometimes 4 or 5 times before the drives/partitions show again. I had no issue like this before running the upgrade or using earlier versions of Ubuntu.

Im having some problems, when I plug in a USB drive or an external HDD to my computer it doesn't mount or show on the Desktop. It only shows up in "disk Utility".
I have tried ALT+F2 then typed "gconf-edit" went to Apps> Nautilus> desktop and check "Volumes Visible" but when I plug in anything in the USB it still doesn't show.
it shows up in the side pane only. I would like it to show up on the Desktop

I just upgraded to 11.04 from 10.10. I have a Radeon 6450 with 1GB of video RAM which should give me pretty good performance, but I'm only getting a measly 60 fps with the new ATI diver (11.4). I installed like this, making sure I'd removed the open source driver:sh ati-driver-installer-11-4-x86.x86_64.run --buildpkg Ubuntu/nattyThen installed the debs and ran an aticonfig --initial. The module builds and installs fine:tnugent@translocon:~$ fglrxinfo display: :0.0 screen: 0OpenGL vendor string: ATI Technologies Inc.OpenGL renderer string: AMD Radeon HD 6450OpenGL version string: 4.1.10666 Compatibility Profile ContextBut this is not good:

Running:Fedora 13kernel 2.6.34.7-56.fc13.i686desktop: xfce 4.6.2Problem: I have a 1TB drive (SATA) with 2 partitions. The partitions/volumes don't show on the desktop.The volume names are:MASSIVEBACKUP.
Facts:1. When I login using GNOME, both volumes (MASSIVE & BACKUP) are listed on my desktop2. My /etc/fstab has long since been edited to reflect these drives3. Using XFCE: Although the volumes don't show on the desktop, they are indeed mounted. I can see them when performing a "df -h" as well as when opening "File System" and drilling to /media - they are both there. I can also access the contents of both volumes within "File System" (using Thunar).4. Using XFCE: I can access both volumes via command line5. Using XFCE: External drives are not affected. I have one external USB drive that shows and when I plug my Android phone, it too shows on the desktop.
After some exploring, I installed the following:Oct 01 22:17:29 Installed: xfce4-mount-plugin-0.5.5-4.fc12.i686I then added "Mount Devices" to my panel, but...as you've probably figured out - they're already mounted.
Here is my /etc/fstab:

I shall start off by saying that I have just jumped from Windows 7 to Ubuntu and am not regretting the decision one bit. I am however stuck with a problem. I have spent a few hours google'ing this and have read some interesting articles (probably way beyond what the problem actually is) but still don't think I have found the answer.I have installed:
Distributor ID: Ubuntu
Description: Ubuntu lucid (development branch)
Release: 10.04
Codename: lucid
I am running the install on an old Dell 8400. My PC has an Intel RAID Controller built into the MB. I have 1 HDD (without RAID) (which is houses my OS install) and then I have 2 1TB drives (These are just NTFS formatted drives with binary files on them nothing more.) in a RAID 1 (Mirroring) Array. The Intel RAID Controller on Boot recognizes the Array as it always has (irrespective of which OS is installed) however, unlike Windows 7 (where I was able to install the Intel RAID controller driver) .Does anyone know of a resolution (which doesn't involve formatting and / or use of some other software RAID solution) - to get this working which my searches have not taken me too?

I want to re-setup a raid array on some older drives using mdadm. That involved adding a single partition on 4 of my drives (3 older, 1 brand new - a replacement drive), using mdadm to create the array, etc. However, upon restarting the box, the 3 older drives do not show up as having partitions and hence mdadm cannot immediately start the array because 'there are not enough disks to start'.For example, if I do an ls command before I restart, I will see:
Code:
ls -ltr /dev/sd*1
/dev/sdb1 /dev/sdc1 /dev/sdd1 /dev/sde1

I recently installed Fedora 12 for use with Amahi HDA. Before installing on the Hard drive I used the LIVE CD to test it out. While using the LIVE CD I could see all my HDD's. My file system, my 2nd Hard Drive, and my Raid 0 Configuration. (2 250GB drives) and could browse all my files on those drives.
After installing the full version on my hard drive, my RAID drives are showing up as seperate drives. I have a Asus P4P800 board using hte SATA raid. I know its FAKERaid and not a true hardware raid.
My goal is to restore the Raid in Fedora and make those drives active. However, i dont want to lose any of the data on those drives. To make sure I wasn't an idiot, i rebooted withthe LIVE CD again and verified that I could see the Raid Array.

I have a load of partitioned hard drives and even though the are refrenced in fstab I still get Bookmark Icons and they are also visable in 'Computer'How do you remove these icon?I would also like the ones not refrenced in fstab to only be mountable via password - lucid seems to just mount when you click, I did change this as in another post but it also made USB keys need a password
Code:
gksu gedit /var/lib/polkit-1/localauthority/10-vendor.d/com.ubuntu.desktop.pkla
change the ResultActive=yes to

I'm experimenting with a K8055 board, connected through USB to our Asterisk server,running on CentOS. If I connect the device I can see it being connected by watching /var/log/messages. Also the device is mentionned in /proc/bus/usb/devices. But when I do lsusb the device isn't showing up and it should be showing up! If it is not listed with lsusb, I can't connect to it through the k8055 executable...

I am trying to setup nfs to mount the drives located on my desktop, to my laptop, so I can watch them on my laptop rather then my desktop. I have both nfs server running on both the desktop and laptop. Desktop is running Arch Linux and the laptop is running Ubuntu, I keep getting this error claiming that the devices dont exist. I restarted all the services on both machines and tried editing my fstab/exports on both machines also but still nothing seems to be working.
Here is my nfs restart log from my laptop [URL]
And now desktop [URL]
Here is the export/fstab from my desktop [URL]
Now for my laptop export/fstab [URL]
There rather the same, but just wanted to include both for each machine just in case there is a distinct difference in something I did.

I've finally found a couple of useful tutorials on setting up RAID in Linux. However, because this is new ground to me, I have a couple of basic questions which I think the tutorial writers gloss over because of their familiarity with the process. My questions are these:
1. Most tutorials speak about setting up only one partition on clean drives. Can I set up more than one (e.g. / and home) to be mirrored as two partitions?
2. When starting with two identical clean drives, do I need to set up my partitions identically on both drives or is it only the partitions that I want mirrored to the second drive?

i find this is an issue which might be tiresome for everyone except for those experts. Esp. for the computers which are dual booting(both windows xp and centos installed in the same computer), that when we are in CentOS we need to switch onto windows immediately. and vice versa. i see this is possible only by shutting down the centos/windows and then restarting onto the other OS.
Can anyone tell me the the solution to work simultaneously both xp and centos without the need of shutting down and restarting There maybe or may not be the solution...but i find the pleasure to know if there is for example, remote desktop connection in windows xp, is there any solution, we can work on windows via centos or vice versa ( in the same machine),

So I didn't notice when I setup my CentOS 5.5 server that I left / as RAID 0 on md1. All the rest are RAID 1. Is there a way I can modify the array to RAID 1 without a risk of data loss? I'm glad I caught this before I setup any other services. I've only setup smb so far...

I'm trying to make a fresh install of Ubuntu 10.04 on my system. I have 9.10 correctly setup on what I see here as devsda2. devsda3 does contain /home. devsda1 is for Vista. They are on a 500Gb hard drive. I also have a second 500Gb hard drive, formerly on a raid 0 with the first one, but now independent (raid deactivated from bios). It is here know as /dev/sdb, and contains other 3 partitions. Raid 0 is not hardware, but is an intel fake raid.
I then have other 4 drives, causing me NO problem.
I start live mode of Ubuntu 10.04 with noraid option. When I try to setup Ubuntu, during the process, where it comes to manually select partitions, the two 500Gb hard drives disappears, such that I'm not able to install Ubuntu on what now is /dev/sda2
If I start live mode of Ubuntu without noraid option, I will see the two 500Gb hd as being part of a raid 0, such that I can't use them.
The other 4 hd normally appear in both cases.
