I am very new to centos and just setting up my disk. I have a dell 1850 with 2 69GB disks. When I get to this screen ( shown below) the disc configuration shows two discs "SDA2" and "69774MB". What I am wondering is this confuration ok. I assume the SDA2 is my secondary disk? Why is it using the secondardy disc and not the primary SDA1?
View 4 RepliesI am trying to install CentOS 5.2, and the installation ran out of disk space after running for about 2 hours.I checked the FAQ, and it said 1.2 GB. The disk is 3 GB. The default install was selected, and I think that it checks for sufficient available disk space before installing. Still, it ran for quite a while before announcing that it was out of disk space.The Installation Guide is not very helpful, since there is a blank page where the disk space requirement is supposed to be. I just picked the default installation. A search of the forums on "not enough disk space" did not return much.

When I get to the screen where I select what drive to install on, there are no drives listed. The hard drives were completely formatted before starting the 13 installation. Do I need to put something on them before Fedora will install?

Yes, I read the manual. On a Dell 6650 system the drive can't be rebuilt because it is not recognized as the correct size. Linux rescue doesn't work... won't find the linux partitions that are still there according to fdisk -l

Here is a thought experiment:
1. Copy vmlinuz and initrd.img from isolinux subdir into /boot
2. Adjust grub.conf to boot to that kernel
3. Reboot to setup
4. Format /boot (actually '/' ) during "fresh install"
5. Proceed with the installation-over-network
I see two possible outcomes:
1. The setup fails to reformat the drive, because it is "in use" by boot kernel
2. The partition is not "in use" and the installation succeeds
Why? Old cluster with broken CD-drives, lacking USB, and no separate /boot partition.
There is a disk 500 gb, it is broken on /boot and on /root and on /dev/sda1 and /dev/sda2. Whether prompt it is possible to redistribute a disk without loss of data namely it is necessary to make/boot and two equivalent on disk volume.

Iīm pretty new to linux and debian and I have a problem with my disk setup. I have a rocketRAID hardware card installed for RAID setup. In addition I have a separate HDD for linux and use the RAID-setup for server purposes. Now, when I boot the system, grub boots /dev/sda1. This does not work and I have to change to /dev/sdb1 for it to find the system files. (although sometimes it works, but in these cases the system does not find the RAID-disks. Thatīs for another time thou).
The strange thing about this, to me in any case, is that "fdisk" reports correctly, with sda and sdb but "df" reports all disks as sda and none as sdb. It also misses a partition of the RAID-disks which fdisk reports. hereīs a screengrab from "fdisk -l" and "df -h"

I want to be able to install multiple operating systems on a disk setup with LVM. I am uncertain as to how to go about this.I read somewhere that you can do it, but that only one /boot partition should used for all systems(they are all linux).get going on this? Do I boot from an installation disk and follow that path some how...or is there some other method I should be following? And how do I use one boot partition for all OS's? I had a problem with this once before..so need to ask, especially with the LVM thrown in the mix.

View 1 Replies View RelatedIt all started when I decided to take the plunge and install Linux, bearing in mind that I am still completely dependent on Windows. I decided to go for Ubuntu, hearing that it is user-friendly and easy to learn. My current machine dual boots to WinXP & Vista. Following the guide regarding pre-partitioning, I decided to delete a partition I no longer use so I can install Ubuntu on there. Using XP's disk management, I deleted said partition, but it somehow also deleted my Vista partition! As a result, I am now unable to boot to Vista. I went back to XP, and ran Partition Magic to fix the partition tables. However, I get an error saying something about the partition's drive letter can't be identified. Decided to resinstall Vista but when it asked me where to install, I noticed that it only shows 3 partitions instead of 4 (my data partition has somehow vanished as well). Then I heard a noise from my HDD, and it suddenly reboots. Decided to log back to XP, but I am unable to boot to XP as well (got BSOD'ed).
Got my XP setup disk to reinstall, but this time, XP setup only recognizes one big partition(250gb).... and below the partition there is a note that says "Setup unable to access disk." I also tried the recovery console, and on the C: prompt when I did the chkdisk, it says something about invalid file path or can't find the path. Tried the Vista install again, it was also unable to access the disk. So what happened? Is my HDD dead? Finally, I thought I'd give Ubuntu a try. Decided to do the "Live CD" first, and wow, nice user interface! Then suddenly, I saw my "data" drive and "winxp" drive! Everything is accessible and all my files were there. I was overjoyed knowing that it didn't wipe out any of my files. So I guess my main question is, should I go ahead and install Ubuntu and will I be able to get those files back? Is there a program similar to XP's disk management? And finally, I know not related to Linux, but how can I boot back to XP?
I want to build a 6xSATA RAID 5 system with on of the disks as spare disk. I think this give me a chance of 2 of 6 disks failing without losing data. I am right?
Hardware: Intel ICH10R
First I will creat a 3xSATA RAID 5, after I will add the spare disk and after that I will add the others disks. This is what I think I should do.
Step 1:
Create RAID Device
Code:
mdadm --create --verbose /dev/md0 --metadata 1.2 --level=5 --raid-devices=3 /dev/sda1 /dev/sdb1 /dev/sdc1
I read that "--metadata 1.2" is the best option. It is true?
Create filesystem on the RAID device
Using this method of calculation:
* chunk size = 128kB (for RAID 5)
* block size = 4kB (recommended for large files, and most of time)
* stride = chunk / block = 128kB / 4k = 32kB
* stripe-width = stride * ( (n disks in raid5) - 1 ) = 32kB * ( (5)- 1 ) = 32kB * 4 = 128kb
Then:
Code:
mkfs.ext3 -v -m .1 -b 4096 -E stride=32,stripe-width=128 /dev/md0
Step 2:
Add spare-disk
Code:
mdadm --add /dev/md0 /dev/sdd1
Is this enough?
Step 3:
Adding disks:
Code:
mdadm --add /dev/md0 /dev/sde1
mdadm --grow /dev/md0 --raid-devices=4
fsck.ext3 /dev/md0
resize2fs /dev/md0
I am having new hardware and IDE driver for that hardware as drive disk image (it8213_centos53.img). CentOS 5.3 installation is working fine with drive disk image at USB and CentOS 5.3 at DVD. Our application uses CentOS 5.3 and we build a custom kick-start ISO for installations. Using that ISO client is going to install on all hardware boxes.
Note while installing :
a) No network connection is avalible.
b) No USB isavalible.
c) No floppy is avalible.
d) Only single CD-ROM is avalible.
So, is it possible to build single custom kick-start CentOS 5.3 ISO which contains dirve disk image and entire installation will be done using that image. If so please let me know the steps to build it.
How to correctly install F11 on the same disk as Windows. I have created the partition but can't tell what F11 install to use to setup as dual boot with Windows XP Pro 64bit.
View 2 Replies View RelatedWhen trying to install Kubuntu 10.04 32-bit (or Ubuntu 10.04 64-bit) it does not show me any hard drive to partition in the 'Disk Setup' (I've clicked all the buttons on that screen to see if I can encourage it!) and will not let me past that point in the installation process (because, obviously, no root file system has been defined). I have done something very bad to my computer. As an aid to selling my computer, I decided to (try to) install Windows 7. I booted into a live Ubuntu CD and used Gparted to reformat my hard drive. After several issues with the Windows boot CD I decided to pull up FastBuild Utility, and did something which included deleting LD and Defining LD again. Didn't make any difference with the Win 7 install. I am now trying to return my computer to a functional state in the sanctuary of Kubuntu 10.04.
Tried installing Win XP which I have installed successfully on another computer. Got an error message: "Setup did not find any hard disk drives installed in your computer" - presumed that was because of something I did with FastBuild Utility (2006). I've tried as many different options in this as I think could make a difference. Booted into DR-DOS and deleted partitions and created a FAT 32 partition. Booting into the live Ubuntu 10.04 CD again and used GParted to create an NTFS Primary Partition taking up all the hard drive. As above and deleting all partitions in GParted. Checking into BIOS and changing the SATA Operation from 'RAID On' to 'RAID Autodetect / ATA' (Now changed back again to the default 'RAID On.').
Loaded Defaults in BIOS - I've been running Ubuntu 10.04 x64 on it since it came out with these settings. At all points I have tried to install Ubuntu 10.04 64 bit, Kubuntu 10.04 32 bit (and Win XP) with no success. In the Kubuntu install, when I get to the Disk Setup part of the installation process it offers me no information whatsoever. My hard drive has all partitions deleted because of my last action in GParted. May need to define a partition. What as? I'm still convinced that my playing in FastBuild Utility (2006) is probably the root cause of this, and so quite likely to be a good place to go to solve this. I think I've set everything as it was, but can't be 100% on that.

I told the installer that the other disks were off limits but it was somewhat confusing at the bootloader page. So, I suspect that I told it boot off the fc8 disk. If that is the case is there a way to restore the fc8 install by somehow rescuing the /boot partition on the fc8 disk?
View 14 Replies View RelatedI am installing a number of boxes with RHEL 6, using a kickstart file I made and put on a boot disk.I am having trouble, however, when using this disk. The boot loader recognizes my kickstart file, but when it prompts me that it can't find the RHEL distro on my disk, and that I need to insert the DVD that contains the distro, I cannot eject the CD. Button pushy, no ejecty. I tried a paper clip to open the drive, but even after inserting the distro disk this way, it doesn't see it. It's like anaconda is wrapped around the mount of the boot disk and won't let go.
There's nothing special I need to have in the kickstart file for this to work right? I have thought about putting an eject statement in the post section, but that isn't even used until the OS is installed is it? I can get around this by creating a distro DVD with my kickstart file, but I'd rather not do that, and use the kickstart/boot disk functionality as intended.
I'm looking to set up a bit of a home server, and am wondering about storage. What I'd like is something like RAID 6, which has good redundancy built-in, but with this being a home server, I'd prefer to start a little smaller and leave room to build it up in future. I'd been looking at commercial products like the 'drobo', which seems fairly ideal, but I'd really like to see if I can do it myself. I understand that throwing the RAID into an LVM will allow for some expansion, but the last time I checked, most RAID setups called for the same sized disks, or at least limited the array by the size of the smallest disk present.
What I'd like is the ability to build a basic framework with a few cheap disks, and then as things start filling up, to be able to add larger ones (perhaps eventually pulling out smaller ones as though they'd failed and replacing them with big ones)
My dual proc, dual core Opteron MSI Master2FAR motherboard failed, and I try to boot a disk, used on this board as boot disk, on an Intel based Gigabyte GA-965-DS3. Both systems are x86_64 architecture.
The OS is on both systems is openSUSE 11.1.
On booting the disk on the Gigabyte, the disk is seen correctly by the BIOS, but not by the OS, and there is no /dev/sdX; no /dev/disk/... either. I am taken to a login shell from the ramdisk.
When I just mount this disk on the Gigabyte (booted with the Gigabyte's original boot disk) everything seems fine. No suprise to me, since the disk was fine, and was unmounted gracefully and physically taken off the MSI before the board failed.
I think that the cause lies in the fact that the harddisk controller on the Gigabyte is different from the MSI, and the driver for that controller is not available at boot time.
I have two questions:
- is my assumption correct, or is something else going on?
- if I am right, is there a way to get this disk booting on the Gigabyte (or on another system, for that matter)?
You might want to ask why I want to boot this disk on the Gigabyte in the first place, since I can mount it and see all data on it. I have a reason for that, but telling that story would make this topic too long, and it's too off-topic. Most certainly I will get to that in another topic.
