Ubuntu Installation :: Multi Distros To Choose Best For Server: What Partitions
Jan 22, 2011
i decided to build a home server on an AMD64 (buyed some years ago) for file storage, printer sharing and something else... I've searched a lot for "the best distros for server" and discarding extreme solution (like command line only) what remains is: Ubuntu, Fedora and Debian
Now the problem: how to install more than one distros on the same hdd? what i know is that i need a bootloader (grub/lilo) and partitions for boot,swap, and remaining space will be split for the distro itself.
I think is a good idea to have a partition only for files (/data) that all distros can access, but for sure i'd like to have one /root and one /home partitions each distro!
I can't understand if the correct way is first of all to install a distro (let's say ubuntu), then set up everything such as partitions and bootloader and then install other distros. I'd like to know if it is possible to manage dinamycally the space reserved for distros, so i'll be able to install 2,3,4,5...distros with no problems.

With the startup disk creator on Ubuntu (Currently running Ubuntu 10.04 LTS) I realised you could boot Ubuntu from a USB and then install it onto the HDD if you wish to. *Side note* Still amazes me you can run a whole operating system from a USB memory stick drive *End Side note* Now My question is: 'Is it possible to have multiple distros of Linux on a USB memory stick and choose which one you wish to boot from when you boot up the computer?'I was hoping to get a seagate portable HDD ((here) and load quite a few different Linux distros on it to get a broader view of Linux than just Ubuntu (Although Ubuntu does rock ).
Is there simple ways of doing this? I have read around this forum and Google and a suggestion was given to install all of the distros onto the portable HDD/ USB memory stick and then install Ubuntu onto it last as its good for picking up other OSes in its GRUB. (Again if my idea on GRUB and its workings are wrong please point it out - got to keep learning)

I have downloaded new version 10.4 of Ubuntu and burn it on CD with power iso, gave it a try to install but after it started from cd and waited to load an error pop up and says it can not install from cd ...then i tried to start live cd and it started Ok with no problem. In live cd mode i tried install again and started well ,1to4 step ok, then at 4 step when it comes to HDD and partitions the window to choose from is blank. No HDD no partitions. but interesting is that in this Os it has partitioning tool in system tools GParted, and whit it i can see my HDD and partitions, even tried format with it a partition for Ubuntu then tried install but problem is the same = blank step 4,.. so on my pc i can not install 10.4
Pc ( Amd 2800+, Mbo ASRock K7Upgrade-600, vga ati 9600pro, rest integrated, hdd maxtor 160gb (Maxtor 6L160M0) I have older version of ubuntu = 8.10 and everything is ok and istall is ok , hdd is visible,installed and works I tried install 10.4 on my friends Pc which has Intel mbo, intel cpu, ati 1550, sound+lan integrated on mbo, 2 hdd on sata 1 on Ata, on his pc i had no problems with install, runs good, sound ok, DSL ok over lan, update ok,..

I'm setting up my laptop to dual boot (default Vista installation and Ubuntu). There's also a possibility I may add XP later as a triple boot.
My laptop came with two partitions already, the second one labelled "Recovery". I was planning on adding three partitions, one for the Ubuntu installation, one for Swap, and one for storing my files (accessible to both OSs). However, this would be five partitions (or six, if I add XP later).
I've never had to deal with this many partitions before and just learned about the maximum of four primary partitions.

I have a MacbookPro 5,1 with 2GBRAM, which successfully dual-boots with Ubuntu 9.04 since a year. I wish to urgently install ubuntustudio, and also wish to have one or perhaps two more partitions, where I may install the latest Ubuntu as well as another Linux distro.
Typically, think of a multi-boot scenario:
Mac OSX 10.5.x
Ubuntu 9.04 <<--working production install, not to be messed.
UbuntuStudio 10.4
Ubuntu 10.10 [just a few days left!]
Fedora or Knoppix or Debian.
if possible, i'd also like to keep one partition free and unallocated, or reformat a partition, if i ever need to install windows. any thing i'd need to watch out for in this? I've got no extra or free partitions, only free space on the mac partition, that i'd like to carve out and allocate to partitions. Also, before i begin, is there a way I can clone my entire mac+linux hard-disk so in the event of a failure i can get *everything* back, mac as well as ubuntu? I bought a hd of an identical size, but use it with Time Machine. I'd rather use it to clone the entire hd.

My drive was set as LVM during installation of FC3 and has worked fine, but now i need to upgrade to some newer distro and would like to "try before i buy" one, without losing my current data and functionality (email and browsing). Once i find something that i like, then i would want to use the new distro and still have access to my old data files.
My thoughts were that i needed to somehow create a non-LVM partition in which to download and install the newer distros, but that is scary at the thought of making a mistake and losing everything. And from the success story it appears that is possibly not necessary since he uses only LVM. i tried using WINE a while back and something in the windows program started reformatting/deleting my linux account in /home and i lost everything, so i'm not thinking highly of virtualizations, and i've reverted to "if it ain't broke don't fix it"...
But now all the multimedia requires newer flash, and new flash requires new browser, and new browser wants new kernel, etc... so the time has come to try the new stuff, even though the old stuff works fine. i have a /boot ext2, and the rest is / LVM. i would like to try ubuntu or debian, knoppix, FC?. Most of the info i've found for multiboot has been anti-LVM, so it has not been useful and i'm overwhelmed by all the information. Could someone who used LVM and loaded other distros give me some detailed pointers on how it works and maybe some successful example scripts or partition tables, etc.?

I have a new laptop, the HDD is 160 GB size, I would like to install several linux distros, such as Debian, UbuntuStudio and BackTRack, the HDD partition would be like this:
- first logical partition (100 GB): 3 ext3 extended partition (1 partition for each distro)
-second logical partition (2 GB): swap
-thid logical partition (55 GB): ext3 /home partition
-four logical partition (3 GB): free space
is possible to share the swap and the /home partition between the 3 distros?

My partition layout is as follows:
sda1: 14GB / ext4
sda2: 10GB /iso ext4
sda3: 4GB /home ext4
sda4: 86GB Extended
sad5: 2GB swap
I have 84GB free space on this hard drive and want to install another distro. Will I be able to create another / and /home partitions for the new distro?

I have a 2GB file which is a dd image of a block device. The block device (a USB-connected flash memory) contains multiple partitions, and therein lies the problem. I want/need to access the various partitions in the image file, but need to do this without actually using a physical flash memory device. If the image was that of a single partition, I could simply mount it on a loop device, and access the filesystem as necessary. However, I can find no kind of virtual block device upon which to write/mount the image.
I've searched the net exhaustively for anything that would seem to allow me to do what I need, but without even a sniff of success. Sadly, I have seen bits of information that suggest "you can't get there from here". Even the outstanding dd tutorial by AwesomeMachine on LQ didn't help. Anyone know of a kind of virtual block device on which a multi-partition image can be written and mounted? Or any other way I can access individual partitions (with various filesystem types on each) and then re-assemble them back to a single image?

I am trying to create a multi-partition USB key to use to kick multiple OS's whenever I need (1 NTFS partition for Windows image and data storage, one ext3 for boot, another ext3 for Linux distros iso storage and the last one as a Fedora live usb with permanent storage).
I am using a Kingston Data Traveler G2 16GB usb key and I have absolutely no problem to create the partitions and all looks fine. The problem I encounter is that although I can format the 1st partition on the usd key to any fs I want, I am unable to do the same on the other partitions. I tried fdisk+mkfs.XXX (ext2, ext3, fat, vfat, ntfs) and gparted, and no luck.
mkfs.XXX gives me no errors when I run it but when I try to mount the partition in Fedora 14 the OS is unable detect the fs. Gparted allows me to format the fs, gives no errors, shows a format successful message, but when it re-scans the device the fs appears as unknown.
I know it is possible to do this as I had a DataTraveler 101 16GB and it was working fine until I lost it.

Simple question, which implies lot of complexity, unfortunately : how to install Clonezilla and mount multi-partitions cloned image disk under DEBIAN ?
Wishing that one day Linux would be so easy and complete as Windows. But we are gaining more users, so Linux will have more apps

I had Windows, and decided to Instal Ubuntu over it, so Windows was gone. Then, on another partition, I instaled Windows. I was expecting to be asked on start up which operating system to run, but this does not happen, presumably because they are in different partition. Each time I turn my computer on, Windows comes up.. How do I get into Ubuntu? I am well aware this is potentially a dumb question by the way.

I will be relocating to a permanent residence sometime in the next year or two. I've recently begun thinking about the best way to implement a home-based network. It occurred to me that the most elegant solution might be the use of VM technology to eliminate as much hardware and wiring as possible.My thinking is this: Install a multi-core system and configure it to run several VMs, one each for a firewall, a caching proxy server, a mail server, a web server. Additionally, I would like to run 2-4 VMs as remote (RDP)workstations, using diskless workstations to boot the VMs over powerline ethernet.The latest powerline technology (available later this year) will allow multiple devices on a residential circuit operating at near gigabit speed, just like legacy wired networks.
In theory, the above would allow me to consolidate everything but the disklessworkstations on a single server and eliminate all wired (and wireless) connections except the broadband connection to the Internet and the cabling to the nearest power outlets. It appears technically possible, but I'm not sure about the various virtual connections among VMs. In theory, each VM should be able to communicate with the other as if it was on the same network via the server data bus, but what about setting up firewall zones? Any internal I/O bandwidth bottlenecks? Any other potential "gotchas", caveats, issues? (Other than the obvious requirement of having enough CPU and RAM).Any thoughts or observations welcome, especially if they are from real world experience in a VM environment. BTW--in case you're wondering why I'm posting here, it's because I run Debian on all my workstations/servers (running VirtualBox as a VM for Windows XP on one workstation).

I used Ubuntu before, without problems but since the 10.04 version it won't recognize my partitions. I formated my laptop and partitioned it, installed Windows 7 64bit, which I need for my work, and wanted now to install Ubuntu 10.04/10. I then used GParted to check my Harddisk and it is having troubles to recognize my partitions, too while Windows finds them. GParted is giving me an error message saying my partitions are oversized. I am still in the beginning of my Linux experiences and so I don't know what to do. I have two 250GB harddisks (how Windows recognizes them),

Xubuntu 9.04 installation CD not detecting any of the current partitions. This all started when I reinstalled windows XP a few days ago.After, the computer wouldn't boot into GRUB and would boot directly into windows.Other threads have dealt with a similar issue, that of overlapping partitions causing libparted/parted/gparted to detect the whole drive as unallocated space. The problem in these threads seemed to be a corrupted partition table, in which the partitions overlapped with each other. So of course I checked the output of fdisk -l for overlapping partitions, but I don't see any obvious overlapping partitions. I've noticed that the partition that used to be linux swap isn't showing up in the partition table at all. I might just be missing something simple here and would like another set of eyes to help me figure this one out. Does the problem have anything to do with the partition table being out of order (ie. not in order of what regions they cover on the drive)? From the liveCD I've run
Code:
sudo fdisk -lu
sudo sfdisk -d
sudo parted /dev/sda print
and have received the following output:
Code:
ubuntu@ubuntu:/mnt$ sudo fdisk -lu
omitting empty partition (5)
Disk /dev/sda: 60.0 GB, 60011642880 bytes

I am installing Ubuntu on the same hard drive as Windows 7. The partitions of Windows 7 have already occupied the left part of the hard drive. From left to right, the Windows partitions are one partition for Windows booting, one for Windows OS and software installation, and one for data which is planned to mount on Ubuntu. I was wondering how to arrange the order of partitions of root, home and swap, i.e. which is on the left just besides one Windows partition, which is in the middle and which is on the far right?

We new have server with VmWare ESXi4.1 and we created virtual machine with CentOS5.6.This CentOS5.6 virtual machine will be used as webserver. We need to backup all files and have access to these files. We are going to keep all websites, databases, backups on data storage (NetApp FAS2000 series).
We have two options to how to use this storage:
1: We can mount storage volume directly to CentOS5.6 by NFS.
2: We can add storage via NFS to VmWare and then add new virtual disks to CentOS5.6 by VmWare vSphere client.
What option would you recommend to use? Which option is better, faster and more secure? My thoughts:If we mount storage volume directly to CentOS5.6 so we can access .snapshot directory there is all snapshots. So it's easy to access all backed up files. NetApp has snapshot system and we can schedule to make snapshots automatically, so we don't need to setup any additional backup utilities in CentOS5.6. But we don't have any NetApp snapshot restoring software license so copy/paste from .snapshot directory is only option.
If we add storage to VmWare firstly (by NFS) and then add new virtual hard disks to CentOS5.6 by VmWare vSphere client so we have to setup rsnapshot(or any similar utility) to make backups in CentOS5.6. But NetApp will also make backups of .vmdk files. So it's like double backups, lol :) If storage crashes so we screwed in both ways, I think.

I have an ATI Radeon HD 3300 on-board video chipset, and an ATI Radeon HD 4350 PCI card. What I want is to have both displays available from one mouse/keyboard. I want to play media on one and have the other as my main desktop.The problem is that with Xinerama enabled, KDE desktop effects do not work (KDE says XComposite and XDamage are not available, even though I explicitly enabled them as extensions in the xorg.conf file), and performance is quite bad. Without Xinerama enabled, performance is great, desktop effects work great, but there's a lot of trouble with full-screen video, and the KWin window manager does not apply in the second display (although I can run a second instance of KWin on :0.1).

KPackageKit sometimes tell me there are packages to upgrade, and some are tagged as bugfixes, and some as security upgrades. Are there any ways to find out from the command line which packages are which? I'd like to only apply a certain class, automatic, without using KPackageKit. Using 'apt-get upgrade' I get a list of upgradeable packages, but no list of which class they are. Is there a way?

I am implementing a proxy server in c++. It is multithreaded(posix).Used CPU : Xeon(8core) Thread number : 8 One main thread, and other 7 thread created by the main thread. The main thread always listen to ports. When the main thread gets a client data it push the request in a queue[there are one queue(total 7) for each thread] based on ip and then give a signal to the appropriate thread. Then that thread gets the request from it's queue and process data and then forward the data to a appropriate destination.
There is another important thing, I assign each thread excluding the main thread to individual core by using affinity.The main thread listens to 5 ports. Test environment: We run the server. The client sends audio data at a particular rate.
1. The main thread CPU usage gets overloaded (above 80%) after a certain load from client.
2. Other cores remain about 0-10%.
The thing is that we want to distribute the load among all the cores equally by multithreading. But how can we do this ? Can the listening task of ports also be distributed ? I need an efficient algorithm for load balancing among threads. The data sent and receive rate of server is about 8.5MB/s. How can we improve this ? we are using gigabit LAN card. When the server only receive data from client it can receive data above 80MB/s. But when it both receives and sends data simultaneously it only manage upto 8.5MB/s.

I want to multiboot several Distros for experimental purposes. My main distro is Ubuntu 10.04.Hard drive is partitioned like such: /dev/sda1, grup bios, size = 977 Kib/dev/sda2, file system ext4, size 1.8 Tib, this is mounted on / /dev/sda3 linux swap, 4.3Gib.My question is can I use Gparted to partition a second space out of sda2, and install another Distro? Do I mount it on / ? and will grub boot see both OS without destroying the kernel of my old distro? I am assuming to partition my hard drive I have to unmount it, but can I do this without using a live cd? So many questions and so little help, because apparently this is an easy thing to do.I am just worried just seems that what I just described is too easy and I will probably destroy everything and have to start over.

Anyone successfully using VNC client on a Mac to control a Debian server?I have the vncserver setup on the Debian machine properly. But I'm having problems connecting to it from both a PowerMac running Tiger and a MacBookPro running leopard.I can connect no problem from a machine running Slack12.2, have not setup port forwarding on my router to connect remotely yet.My Debian machine is running the latest stable release of squeeze with KDE4.I originally tried this with RealVNC Enterprise for OSX but I'm not gonna buy it so I need another alternative after the 30 day trial ends as they have no free version for OSX.
The situation is that I do freelance graphic design on the PowerMac with Cinema4D and Photoshop so I spend most of my time on that machine which is located in my home studio in my attic. Aside from the MacBook and a Dell desktop(family machine)all my other machines and network hardware are in the basement. So to go from the attic to the basement everytime I need to do something on another machine is not practical, and the only other machine I need to access on a regular basis is the Debian box in the basement, this makes the most sense.
I also have a 14 year old living in the house and he's fascinated by all this and will meddle in anything he gets the chance to so all the Linux machines and network hardware need to be behind lock and key.

I've built a system with windows 7 on one hard drive and Ubuntu 10.04 64bit on the other, and would like to choose OS on startup using Grub. I installed each OS with only that drive connected in isolation. I then connected both drives and pointed the bios startup at the Ubuntu drive. sudo os-prober sees the windows 7(loader) and sudo update-grub has given the windows option on startup. However, when i choose windows in Grub I get 'error: no such device' and 'error:invalid signature'. Windows starts ok when the drive is chosen from the BIOS.

I appologize if this has already been posted but there are 1001 pages here and I did do some searching - I'm just soooo tired by this point. This whole linux thing is starting to lose it's luster. I've never used linux before and wouldn't know how do deal wtih command line anything - whether its understanding what the system generates or entering it.
For the last 3 days I've tried to install, first - xubuntu, then openSuSe, then ubuntu desktop on my desktop unit then to run ubuntu netbook live on my laptop with the intent of doing a permanent install (if I could see I would be able to get everything working right by trying live first).
So I follow the instructons given on the ubuntu site, using the universal usb creator - it tells me that the operation was successful or something like that. So I proceed to 'attempt to' boot from usb but I find out my bios (on the laptop) does not support booting from usb (go figure!). So I go get this thing called PLoP, burn the .iso to a cd, put the cd in my drive and the usb inserted in the computer too and I reboot and enter my boot menu, select to boot from the optical device (my cd with PLoP on it) and use PLoP to select and boot from usb. Ubuntu runs for a bit I get past the logo with the status bar under it, then I get all this techo whatchamo spit out at me on the screen. Don't know what it means, just know it means I won't be enjoyin any Ubuntu tonight. Very sad.
I did manage to type in help and hit enter and in the list of commands given I noticed one that I though was interesting. "exit" So I put in exit and hit enter and it spit out a bunch more stuff at me. I only mention this because that is what is in the pictures I've attached. One pictures is before entering "exit" (on the laptop) and the othe after entering "exit" (on the laptop). There is also one that shows the screen from my desktop (after entering "exit"). I tried to run Ubuntu live one last time on it right after my last laptop fiasco; and, if you notice, some of the same information is given between the desktop and laptop. (matching infromation between the machines is after entering "exit" on both machines).
I attached the pictures and specs on my laptop hoping they may be useful. I've done all I know how and I'm just starting to get really tired here. If I wasn't so sick of Windows I'd have probably given up by now. I just can't bring myself to blame Ubuntu though. I am certain that Ubuntu is fine. Its either, first, user error, or somthing with my machine. Just that Ubuntu says the same thing about both machines. Hope someon can help. Sorry for the long post.
