CentOS 5 :: Boot Setup From Partition That Is Formatted During Setup
May 5, 2009
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.
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...
[root@ftpserver ~]# df -h Filesystem Size Used Avail Use% Mounted on /dev/md1 16G 3.0G 13G 20% /
I've looked everywhere for a satisfactory answer, to no avail. I wish to triple boot xp/98/ubuntu 10.10. Is this an appropriate HDD setup? (it looks like this in partition magic pro srever 8.05)
There is nothing on any of the drives at this point. (I am submitting this on a crappy 233mhz win95 laptop)
Here's the information i've gathered so far... Install in the following order: 98, XP, Ubuntu XP's drive label MUST be "SYSTEM" (I think?) Installing multiple os's is easy (i've read) if you hide unused partitions during install (ie. if installing XP, hide C:WIN98 and *:UBUNTU partitions) but i can only do this with FAT formats, and if i do that, the dirve letter changes, which is a problem (i suppose i could manually hide/unhide, and set active the partition I want at every boot-up....(Damn))
And here's a couple more questions SHOULD I make everything fat32? do they have to be primary to boot? ('98 on an inactive partition won't load) Once they are all installed... where do i put grub? Do i put it in first? Also, I deleted my dell utility partition to do this, is that a problem? (LOL, I have NO idea what I'm doing...Fck)
Like i said, finding information about the partition setup (logical/primary) is damn near impossible. Even if it's just a "Ya that'll do for a setup"
I'm gonna keep experimenting, since there's no longer anything to lose on my HDD, and i'll report back any improvements I come across
I have created 5 partitions:2 GB ext320 GB ext310 GB ext320 GB ntfs400 GB ntfsI have already installed XP on 20GB ntfs. Will dual boot work if I use the 3 ext3 partitions to install Ubuntu?
Well Fedora 14 sees my Emu soundcard right out of the gate with the live cd! I have windows 7 installed right now. I would like to install Fedora 14 from the live cd to have a duel boot setup. What I am trying to do is just give Fedora 60GB of the drive and keep the rest for Winows. How can I go about this with the live cd. I am sure it's been covered to death but I couldn't really find it.
When I installed Ubuntu I set it up to dual-boot with windows and didnt put much thought into the partition sizes, and now I want to make the ubuntu partition bigger. I shrunk the windows partition from gparted fine and then booted up off my ubuntu 10.04 disk to make the ubuntu partition bigger, but it won't let me do so from gparted. Attached is a picture of how my hard drive's currently set up.
i have an acer aspire one with a 250 gb hdd the hdd is currently partitioned into two parts part 1 - 85 or so gb, has windows installed part 2 - the rest which is currently unallocated. i am trying to install ubuntu so that each has its own section and will dual boot once in the ubuntu installation window, how do i set up the partition to achieve this? i am trying to install ubuntu 10.10 netbook
I have a computer with windows xp on it, and i want to dual boot with fedora 11. I have 2 hard drives in it, 1 500gb HD and 1 350gb HD. the 350 isnt much concern b/c its just sitting there all free and unpartitioned right now. Now my 500gb is split into 3 partitions, a 20gb(with xp installed on it) a 105 gb with pretty much nothing on it and a 350gb with all my data.
My problem is I'm trying to resize my 20gb partition through the fedora 11 installer and when I tell it to resize say to 10gb it starts and fails the resize. its a NTFS partition and the windows stuff on the partition is only about 8gb. any idea whats going on? the only error I get is "The resize has failed"
Basically I have a triple boot setup on a mac pro tower. Windows /osx /centos 5.3 everything was great until I tried setting up my Wacom. I did get it setup but in the process revealed a problem I was having that I didn't notice until this point. Mind you my system boots perfectly everything runs perfectly except I believe my DVDrom and rear usb ports are trying to share the same IRQ and from what it looks like they don't want to play nice with each other. Eventually CentOS kills the IRQ thus killing both devices. Everything works fine on the windows and mac osx side. I have tried unplugging and replugging the DVDROM, I wanted to try another ide channel but the motherboard only has one. I have changed the device from auto to master to slave. When the DVDROM is removed i have no IRQ errors in my dmesg. I forgot to add that adding IRQpoll to my grub boot pretty much destroys the system.... hard lock within 20 seconds of loging in. In CentOS, is there anyway that I can force the DVDROM to it's own IRQ?

Q1) I was wondering if it is possible to Dual boot Ubuntu with Windows XP on a 1TB RAID-0 setup ?
Q2) Also, is it possible to create a SWAP partition (for Ubuntu) on a NON RAID-0 HDD ?
Q3) Lastly... I read GRUB2 is the default boot manager... should I use that, or GRUB / Lio ?
I have a total of 3 HDDs on this system: -- 2x 500GB WDD HDDs (non-advanced format) ... RAID-0 setup -- 1x 320GB WDD HDD (non RAID setup) (The non RAID HDD is intended to be a SWAP drive for both XP and Ubuntu = 2 partitions)
I plan on making multiple partitions... and reserve partition space for Ubuntu (of course).
I have the latest version of the LiveCD created already.
Q4) Do I need the Alternate CD for this setup?
I plan on installing XP before Ubuntu.
This is my 1st time dual booting XP with Ubuntu.
I'm using these as my resources: - [url] - [url]
Q5) Anything else I should be aware of (possible issues during install)?
Q6) Lastly... is there anything like the AHCI (advanced host controller interface) like in Windows for Ubuntu?
(Since I need a special floppy during Windows Install...) I want to be able to use the Advanced Queuing capabilities of my SATA drives in Ubuntu.
I'm trying to take my current windows7 (x64) setup and make it into a dual-boot setup with slackware 13.0 (x32) and am hitting a brickwall. I guess I would like to know if I can salvage the situation without formating my windows drive. I fully intend to, but I had hoped to not do it this month. I'd like to get dual boot going so I can master it and acquire all the files/drivers I'll want and then format and do it 100% right next time.
Currently I have windows setup on a 3x 500gb Raid0 onboard array which itself has been flawless. After I shrunk my current partition size to give me about 25gb of free space I proceeded to setup Linux, and I was unable to perform the cfdisk portion for partitioning the array for Linux.
I tried using cfdisk: /dev/hdx (a1-a3,b1-b3) /dev/sdx (a1-a3,b1-b3)
I even attempted to locate with: cat proc/partition and tried using cfdisk on every device it located. It always said it was either an unknown partition table and should I start at zero, or bad partition. I was of course too concerned over my windows setup (which has almost 1tb of stuff I have not backed up) to go any further into the unknown.
PS: I have used Slackware before, back at 8.1, 10, and even a very brief interlude at 12.0, this is my first attempt on this computer however with 13.0, it is currently running fine on my laptop and my PS3 (Laptop is even dual booting 7/Slack13. Albeit without raid)

I am busy to do some tests using the Adaptec 1430sa hardware raid controler .I started the setup by generating the raid 1 aray and it worked ok .I did the regular setup of Cent Os 5.5 64 bits all worked ok but the system do not boot .When I start the box it enter the minimal grub screen .I tried to install a first time on the MBR like suggested and how it need to be done for soft raid setup .nd I tried to install it on the first cluster from the boot sequence like possible on second choice
We are trying to set up a NIS server on a CentOS system. We need to have a NIS server which can provide NIS authentication to a couple of clients. We are practically new to all this stuff.
Just googled to find some ideas about installing ypserv and ypbind and portmapper. We did all that and also started them successfully. But now the clients are not able to join to the NIS domain . The error log states "YP_DOMAIN NOT BOUND".
I guess we have not entered the /etc/yp.conf, /etc/hosts files properly. Please let us know the detailed steps to setup a NIS server .
Also, please let us know what entries should go into the different /etc/<file_names>? What is meant by HOSTNAME in the /etc/hosts file?
Is there any other files which need to be changed? Are we missing any steps?
Also to add-on, while executing the ypinit command we faced the following error:
At this point, we have to construct a list of the hosts which will run NIS servers. localhost.localdomain is in the list of NIS server hosts. Please cont inue to add the names for the other hosts, one per line. When you are done with the list, type a <control D>. next host to add: localhost.localdomain next host to add:
I am trying to install windows 7 on my harddive, I am running ubuntu 10.04 and have windows 7 on DVD.I was until recently also using uberstudent, which I deleted (100 gigs) to make space for windows.However once I get to the windows start up I get a message: setup cannot detect or create a partition for this partition. (not word for word).
I have Vista Home edtion and Linux, I have formatted Linux partions and now that Grub is not letting me boot into Windows..I had C:wIndows D:New Volume and rest of the space was E:
I ended up setting up a basic linux file server as a pdc for that office. Our main office is a windows 2000 ads domain. The two offices are connected with a vpn. I only have two users at the new location so I simply have the linux and samba usernames/passwords setup manually. I would like to know if it is possible to setup a domain trust between the two sites so I don't have to create a username/password in the remote site for every user at the main office to access. I did some searching but came up empty.
Im trying to setup multiple domU through the default bridge setup. I am able to access only one of them through the network at a time. If you ping one of the domU it works perfectly but you cannot ping any of the others until you stop pinging the one and even then it takes a bit before you can. Ive looked around for a while and seen similar problems but nothing ever seems quite the same. Im probably missing something really stupid. Or is this the way the bridge is supposed to behave? Do i need to use a routed virtual network?
I want to setup a FAI server for which I was looking for the best method of mirroring the Debian Lenny. I want to setup a local mirror with the best method available for mirroring. If it is ftpsync, please provide me some best ways of doing it. I tried ftpsync mirroring but that was not getting properly working due to insufficient I want this mirror to be accessible in my FAI setup so that I can start the installation on multiple machines and start the updates and package installation to be done from the same local mirror.
I've been all afternoon trying to install Ubuntu Lucid on my fakeRAID 0 configured (2) HDDs and am unable to set GRUB up. The fake RAID setup is provided by Intel Matrix Storage Manager, it is correctly enabled and the BIOS is also correctly set up -- in fact, I've managed to install Windows 7 with no significant hitch. After struggling with partioning the drives (had to follow advice I found on a very helpful guide online [0]), creating the filesystems AND getting Ubuntu's installer to actually do what it is supposed to do, I now cannot seem to set GRUB up. My system, as it stands, is unbootable at all; via live CD only.
This is how the RAID0 dev is partitioned: Code: # fdisk -l /dev/mapper/isw_ecdeiihbfi_Volume0 Disk /dev/mapper/isw_ecdeiihbfi_Volume0: 1000.2 GB, 1000210694144 bytes 255 heads, 63 sectors/track, 121602 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 131072 bytes / 262144 bytes Disk identifier: 0x6634b2b5 .....
Im trying to set up my workflow to a terminal-based setup, so that accessing my computer through SSH will provide many of the things I need and use right off the bat. I have Mutt working great with my GMail account, so that's good. I do have a question though. Using the application Calcurse (featured on Lifehacker a few days ago, [URL] I am at a loss to figure out how to interface with Google Calendar. Is there a trick that Im missing, or does anyone know of another terminal app that plays better with Google Calendar?
Also, I was looking for a 'Digital Clock', essentially, again, a terminal/text based large print clock; similar to the one in the lower left corner on the attached pic. I was looking for a telnet server from the Atomic Clock, but no such luck so far.....
With new installs of openSuse 11.4 I've hit a printer problem. I can run hp-setup (or hp-toolbox) for the wireless Officejet j6410 and it is recognised. The right driver is selected. Then when I choose add printer it all falls over with the error message: error: Printer queue setup failed. Could not connect to CUPS Server Is user added to "lp" group(s) error: Fax queue setup failed. Please restart CUPS and try again.
The user is added to the lp group. I have this problem with my 64 bit desktop and 32 bit laptop installs of 11.4, it all worked perfectly in 11.2. I've used the Cups web interface to set up the printer now and can print from both machines, but I would prefer to use the hp-toolbox, which has several convenient features. Where do I go from here?
I am trying to setup a 5 monitors setup using 3 cards, but I am stuck at 3 monitors for now. The third card is not plugged yet, so the current setup is:
NVIDIA 8800GT (binary driver 195.***) --->1680x1050 LCD (VGA) --->1680x1050 LCD (DVI) ATI HD5450 (3 output, but I think the OSS driver only support 2, corrdct me if I am wrong) (OSS driver) --->1280x1024 LCD (DVI) ---> 1366x768 TV (VGA)
What is the default partition setup that the ubuntu installer uses? Ie which directories get their own partitions (If I remember correctly by default it doesn't just throw everything onto one partition, assuming you're installing onto a fresh hard drive).
i tried installing windows 7 on a partition on my laptop but i'm getting this message:"setup was unable to create a new partition or locate an existing system partition "i tried googling and found that it has something to do with the number of partitions:my hard disk layout right now:
I am trying to install ubuntu 9.1 on a 320 gig hard drive. I have manually created a 45 gig partition. When I try to install ubuntu from the cd,,, I can not install it.
How do I have to setup the 45 gigs to install Ubuntu on it? Swap partition? EXT2?
I am a newbee and am not too sure, but anyway, here it goes. What would you recommend as a partition setup for a laptop with 1gb ram and 160gb hdd? Please note, the setup needs to be able to keep all documents, settings and programs on updates and whatnot.
I'm thinking about installing Arch soon, but I was wondering what the optimal partition setup would be. Bhalash on #ubuntu recomended:
boot as sda1 swap as sda2 personal data (not config) as sda3 ** the extended partition as sda4 which would include -Ubuntu -Arch
This would not be a home folder, it would just be for person files like pictures or music. The OS's would have their own /home which would contain symlinks to this partition. Does anyone see anything wrong with this setup or have a better idea?
Currently on my setup: sda1 is a broken ubuntu 10.10 sda2 is extended sda5 is swap for broken install sda6 is my working install sda7 is swap for working install
So keep in mind how easy it would be to move the partitions around in your response. I haven't found a way to move something out of extended without frying the data.
