I'm trying to install CentOS on my macbook over a Fedora Core installation.I'm getting this warning:
Quote:/dev/hda currently has a gpt partition layout. To use this disk for the installation of CentOS, it must be re-initialized, causing the loss of ALL DATA on this drive.
I'm at a stage where I can start using Linux for all the tasks that I currently do on Windows and am keen to make a full switch to Linux. I have played with Linux a few times over the years, installing different distros etc, but I've never set up the hard drive partitions manually. I only want to make the switch once I have a good grasp of how to configure the hard drives as I have a lot of precious data.
A question I have is that normally I would set up a small partition for the OS, then have another large partition purely for data. What would be the best way to recreate this kind of set up with a Linux file system (i.e. keeping OS and user data separate)? Where would be the best place to store a mass of data that wouldn't necessarily be associated with one particular user? I've seen about having a separate partition for users home directories, but I don't really want the data associated with one user so it would seem more logical to store it somewhere more general.
Yesterday I got my new workstation featuring:
120 GB - OCZ Vertex3 MAX IOPS
300 GB - Western Digital Velociraptor (10k RPM, about 4ms avg. seek)
2x2TB Samsung Ecogreen F4
The system will be running Ubuntu with the main purpose of doing lots of Java development. Occasionally I have to develop Java in a Windows VM; for this I need fast VMs. I read a lot about SSD wear and maybe it is a bad idea to put the Eclipse workspace on the SSD, because of all the little writes the builds do. Perhaps the workspace (and thus /home) might find a better place on the Velociraptor which is real fast. How should I partition the whole thing to get the most out of it. LVM might be an option, too. Maybe putting a third partition on the SSD for one VirtualBox image. Currently I am thinking:
SSD: 2GB /boot, remaining space for / Velociraptor: LVM spanning the whole drive. 150GB /home Remaining Space for /virtualMachines or something like that Samsung drives (LVM over both or one Volume Group for each? - Latter would be better in terms of data security, because if one drive in a big volume group fails everything is lost)
For a fresh installation using manual partitioning, one single disk (IDE).
If I selected:
For the root partition, I would like to use ext4, 10GB, but by default, the partition type 'extended' is suggested. Would there be any difference (advantages, inconveniences) if I selected the primary partition instead?
I have several partitions on my hard drive, and like to use the 'Create Custom Layout' option during the installation process, to make sure that I don't loose any of my existing partitions or the data on them.
I have attempted a minimal F12 installation from Fedora 12 DVD. But the 'Create Custom Layout' option is not an option in the menu.
How do I install F12 and tell anaconda exactly which partitions I want to use and format?
My current working partition layout is shown in the attached screenshot.
I want to use the following custom partition layout during the initial F12 installation:
Code:
/dev/sda2 / Fedora-12-root
/dev/sda3 SWAP
/dev/sda11 /var/log/ var-log
/dev/sda12 /tmp tmp
This allows me to share existing partitions between my current working F10 root partition, and the newly-installed F12 root partition. So if there are problems with the new F12 installation, I still have a working F10 system to fall back on.
The other partitions with data on will be mounted when the intiall installation has been completed
Trying into install fedora. I am setting up my system as a dual boot over two drives. I have set up a custom layout and whenever I get to the step to write changes to disc it crashes with an unhandled exception. I have tried multiple times now, it always crashes.
Here is the first line from the exception report:
anaconda 15:31 exception report

I am trying to install fedora15, my devices are as follows:
/dev/sda1- contains windows recovery
/dev/sda2- contains windows vista
/dev/sda3- free space
/dev/sda4- where fedora10 is existing.
Basically I want to scrap the fedora 10 in /dev/sda4 and install fed15 on the place (ext3). During the installation process fedora asked me, Which type of installation you want? I choose 'create custom layout'.
Then in the next window that appeared I choose /dev/sda4. Then it gives me four options like
Create Edit Delete Reset
I want to know what does this Delete mean. What will it do, will is erase all the older partitions within /dev/sda4 i made for fedora10 (previously I made three partitions /boot, swap, /) or will erase /dev/sda4 itself. I am scared to continue installation further.
I ve got Eeebuntu 3.0 installed on one partition, and Fedora 12 installed on another, sharing the same /home partition, and within that, I have them sharing the same user folder. It complicates matters as Eeebuntu (with it's Ubuntu 9.04 base) still has Firefox 3.0.16, and Fedora has 3.5.6 (Adblock no longer works in Eeebuntu, I stupidly upgraded it in Fedora). I want to keep the same partition layout, but resolve these conflicts. Is there any way I can change the /home folder for Fedora, or Eeebuntu so that each one has different settings, but still be on the same /home partition?

Repartitioned starting at cyl 10. mkfs worked fine then. FC12 installer still could not initialise disk, however. I guess it looks at block 1, to initialise before it offers diskdruid, so it never gets to see my custom partition layout. How can I force the installer to accept my custom partition layout? Is a bad superblock at block 1 a fatal, throw-the-disk-away fault?
Running Ubuntu Lucid Lynx, GNOME 2.3Keyboard Preferences utilityAdding any Spanish language keyboard layout makes my Alt_R not work in ANY layout!

In the last attempt I did, sdb,sdc and sdd all had the correct ordering of partitions, but sda looked like above, which means I would need to assemble by boot array partition array as /dev/md0 = /dev/sda3, /dev/sdb1, dev/sdc1, dev/sdd1
Why is the partition numbering moving around as I create them?
3 partitions (in order): Windows 7, CentOS and shared data partition.
I need to increase the size of the Windows 7 partition (c:windowswinsxs seems to be something not easily remedied).
GParted didn't work in moving things around (bad sector) so I wiped out its partition (# 2 out of 3) and I was able to increase the size of the Windows 7 partition (I can reinstall CentOS easily and not much work lost).
Except ... no more grub menu (unsurprising). This incantation does allow me to boot into Windows 7.
Is there any way of rebuilding the grub menu short of reinstalling CentOS (5.5)?
I have a laptop that came with Windows Vista (64-bit) installed. I created a new partition and installed XP (also 64-bit) alongside it.Last night I shrunk my XP partition and created another new partition and installed Linux (CentOS 64-bit) on it. I made an error in judgment and didn't allocate enough space, so I need about 10 more gigs for the Linux partition. It boots up and runs, but I need about 10 more gigs of storage for the files I want to keep on the partition (and yes, they have to be on the partition, I definitely need to know how to do this, not a workaround)I went into Vista and shrunk the XP partition by 10 gigs, so now I have 10 gigs of free, non-partitioned space.
As it stands, when I start up the computer I get the GRUB boot loader. I can boot my Linux install or choose "Other" and be taken to the Vista boot loader. From there I can choose XP or Vista to boot.So, my question is... what is the best way to append the 10 gigs of free space to the Linux partition? Is this something I should do inside of Linux? I have the option to do it in Vista, but the partition shows up as "healthy" but without a file system type.I just don't want to screw up the boot loader, partitions or anything else.This isn't my area of expertise, so if anyone could give me a good suggestion or solid answer

I have a disk 300GB I want to make partition using LVM any time I type lvcreate /deve/parta or pvcreate /dev/parta I get a message ( bash: pvcreate: command not found ). I have CentOS Linux 5.4.
How I know if LVM is installed on my machine?
I tried to reinstall Centos, and the reinstall failed due to a flash disk being pulled out in the middle of the operation. I am left with an un-bootable system and I want to access my data, if possible.
Prior to the reinstall the disk info was:
== BEGIN cat /etc/fstab ==
/dev/VolGroup00/LogVol00 / ext3 defaults 1 1
LABEL=/boot /boot ext3 defaults 1 2
tmpfs /dev/shm tmpfs defaults 0 0
devpts /dev/pts devpts gid=5,mode=620 0 0
[Code]...
So, The disks are still intact (I hope) but the LVM information is gone.is there anyway I can access /dev/sda2? When I try mounting it from the Rescue environment the command hangs, i.e. nothing happens.
I have a default centos 5.x install on an 8GB hard disk. (This means the volumegroup is mounted to / ). I've increased the size of that hard disk to 12GB. (so yes, fdisk says my disk is 12GB)
I now need to increase the LVM to use the 12GB instead of the 8GB. Every single article I've come across says:
"run lvextend on your vg you want to increase, then unmount, reboot, run live cd or whatever and then run resize2fs".
But of course lvextend +anyG returns an error saying not enough free extents
lvextend +100%FREE returns saying the extents matches extents
How can every the google result be wrong? How can I simply tell this LVM that it's now a few gb larger?
I have an installation with a big LVM partition that has only swap and / partitions. /boot is located in a separate partition outside of LVM.
Is it possible to add more partitions like /home, /var, /usr , /tmp in the existing LVM partition on the fly without rebooting?
/etc/fstab:
/dev/VolGroup00/LogVol00 / ext3 defaults 1 1
LABEL=/boot /boot ext3 defaults 1 2
tmpfs /dev/shm tmpfs defaults 0 0
devpts /dev/pts devpts gid=5,mode=620 0 0
