OpenSUSE Install :: Moving /usr To Separate Partition?
Jul 24, 2011
I have a dual boot system with Vista and OpenSUSE 11.3 . Linux is distributed over 2 partitions: one for /home and one root partition for all the rest. As this root partition is getting filled, I thought of taking a 10 GB partition from the Vista partition and using this for the /usr folder (= 6 GB). This partition is a primary partition, while the rest of Linux is on secondary partitions.To be save, I renamed the existing /usr to /usr-old and created an empty /usr as mount point. I changed fstab to load the root partition, the /usr partition and then the /home partition.But when I started the system, there were a lot of errors about files not found in the /usr folder, lthought this folder and is content were clearly present when browsing the filesystem. What went wrong? Hard links? Other system configurations to change? Not possible to put /usr on a separate partition?

Trying to dual-boot OpenSolaris and FC10 is difficult because Solaris grub doesn't know about ext3 and Fedora grub doesn't know about ZFS. I was able to rescue my FC10 installation by creating a new FAT16 partition and restoring /boot to it from a dump, and then doing a grub setup to it. A complication is that anaconda doesn't seem to be able to find /dev/md0 (both the Solaris and FC10 installs use mirrored disks).
This process moved the FC10 ext3 partition from /dev/sda3 to /dev/sda4, but the other half of the mirror is still /dev/sdb3.
When I boot FC10 I get a "can't load image" error from grub, but it still loads FC10 successfully. It makes no difference if menu.1st/grub.conf has "root (hd0,1)" (the FAT16 partition) or "root (hd0,3)" (the FC10 ext3 partition).
If a future yum update were to try to install a new kernel, my FAT16 partition would not be updated. It seems to me both these problems might be solved if I could move /boot from /dev/md0 to /dev/sda2 (/dev/sda2 is the FAT16 partition).
Rather than go through yet another install, would the following work?
from FC10, move /boot to (say) /boot.0
mkdir /boot
edit fstab to include "mount /dev/sda2 /boot"
If I try this and it doesn't work, I can't see any way to undo it since anaconda doesn't seem to be able to mount /dev/md0. If a grub guru sees this, perhaps they could suggest a better alternative, or if not, whether this will work or not.
Additionally, although there are two alternatives in menu.1st/grub.conf, grub doesn't display a menu - it goes directly to boot. Any idea why? I suppose this might be a Solaris stage1 grub problem...
Since FAT16 doesn't support links, it isn't possible to link grub.conf to menu.1st. Are they both required?

P4 2.4gHZ 2.0GB Ram I have tried to do some reading on this by googling and such, but it is all a bit overwhelming and so many posts/articles want to deal with dual booting which I am not planning to do on this machine. I am trying to find some info on whether it is better to have a separate boot partition. As in, separate from root partition. I have read that a separate boot partition makes for a quicker start and better recovery if system crashes. I will shortly be installing openSuse 11.2(KDE) [currently on 11.0] and I want to optimise the partition scheme so that it is the most efficient. I have a 160GB HDD that will be housing this new installation, so space is not a problem. I am only user on this machine. Currently, it is just partitioned as such:
2.0GB - swap [because I read it should equal Ram]
32.0GB - /
40.0GB - /home
76.8GB - extra storage [Not really necessary as I have 2 other HDD on system 1 - 320GB and 1 - 200GB]
Also, is it recommended to have separate partitions for /tmp /var or any other /nnn ?

I want to get into the Linux world and trying to install openSuse 11.3 on a separate partition, so I can start getting familiar with it. Installation started and PREPARATION was OK. INSTALLATION WAS OK. While doing Automatic Configuration after a little while the program stops (it hangs). I have to restart the computers by pushing the hdw reset button.
At next reboot, at the partition menu I choose openSUSE option; the program starts and after a while it says that previous installation failed and ask me if I want to retry. I do choose yes, but than again same thing happens - hangs and does not complete automatic configration (which by the way seems to be the last step of the installation). PC is a 2,8GHz, 1GB RAM, Windows OS XPHome and Service PAck3, and now partially loaded openSUSE11.3. OS

I installed openSUSE 11.2 on an external HDD to test. I think it's brilliant, and want to move it to an internal HDD. What is the best way to do this? I don't want to lose all the programs / tweaks I've made to SUSE so far.
Coming from the Windows' world, it's as easy as taking an image of a partition and restoring it over a new HDD partition.

I'm trying a fresh install of 11.2 but I couldn't figure out how to make the whole installation on the same logical extended partition.
It always wants to create a separate /home partition.
I have a second HDD with NTFS only for backup purposes, but the installer puts a grub entry for it too (windows 2). And this HDD is not even bootable. I don't have the balls to try to boot from it and see what happens. How to get rid of it?

Saw a reference to putting the swap partition on a separate drive--just minutes after I was considering that approach. Can't find anything recent on the topic, so asking: Is there an advantage to having /swap on a separate HD from data on /home? My thought was that both disks could be active at once, perhaps speeding up a busy application.

I am setting up a LAMP server for my home LAN. I want to move the data out of / into a new disk partition for ease of backup and especially away from any clean installation I might do. What
I have in mind:
Shut down MySQL and Apache
Make a new partition, format as ext4
Mount new partition on /mnt
Copy all of /srv to /mnt
Copy MySQL stuff from /var/lib/mysql to /mnt/mysql
Update /etc/my.conf to point to /srv/mysql
Unmount /mnt
Update /etc/fstab to mount new partition on /srv
mount /srv
Start mysql, apache
Will a fresh install or upgrade keep its fingers out of /srv, in the same way as /home? Or will those parts of apache installed in /srv/www be updated?

using Opensuse 11.3, I have used Ubuntu 9.10 in the past and have had a blast with Linux. I have to rehash some of my old skills that I have forgotten in the past several years..I installed 11.3, everything is working fine. However, I just releazed that after I installed it, I used my whole partition (Not Windows 7, or I would've been in hell). My Windows 7 is in Raid 0. My second HDD is 1 TB and 11.3 is on there. So, how can I trim down let's say 100 GB and just give the rest to Windows (800gbs). I need that much because I do editing for videos, etc. So, once again, how can I trim my partition and use it for Windows 7.

I have an 80 GB XFS / partition which is dying. Got some errors like this:
ata9: SError: { UnrecovData Dispar BadCRC Handshk }
It's not a problem to create another partition, I've got 2 500GB and 2 1TB disks, all EXT3. I've also 2 80 GB disks, 1 for / and 1 for /home. I will remove the 2 80 GB disks but I have a lot of stuff compiled myself. I use openSUSE 11.1. Is it possible to create a 80 GB EXT3 partition on each of the 500 GB hdd, 1 for / and 1 for /home and move the data to it? must it be done with the DD command or can I easily copy everything within a live-cd. The /boot and swap are already on one of the 500GB disks, and there is no bootrecord on the 80 GB disks.

How would I go about moving a separate home partition back to /, and be able to delete the /home partition? I'm assuming I would have to copy the contents of /home to the root partition, and change fstab at the very least.

A while back I ran into the situation of running out of space on /boot. When I last installed Suse I just went with the recommended LVM layout, which proposes a very small /boot partition. When you run out of space you are now faced with resizing the LVM, which Gparted unfortunately does not support.In Googling around I did not find a concise guide, so I collected the information I needed and and then wrote a guide on the steps I used to resolve this issue and it is available at Resizing Default LVM Partitions and Moving /boot - Mine the Harvest
I found using EVMS from a live CD to be quite simple and was able to create a new /boot partition and reconfigure grub to use it in very short order. I was quite impressed with how easy to use EVMS was and the options it provides. (I think that the default LVM layout the Suse installer proposes is overly conservative on the size of the /boot partition. Why not allocate a few hundred megs, especially considering the size of drives today? Perhaps Suse will soon move to using grub2 and eliminating /boot altogether, but for now the very small allocation of space can be a bit of a pitfall for users -- especially when they are not familiar with resizing LVMs and reconfiguring grub. Of course moving to grub2 also introduces its own complexities too.)

I just installed the 11.4 version after using numerous previous versions. During this install the /usr directory was placed in a separate partition. How would I go about placing it in the partition with all the other running directories?

I just bought a new hard drive so that I could convert my XP-only machine into an XP-Ubuntu-Windows 7 triple boot machine.Since the drive is absurdly huge (1 TB) I wouldn't mind throwing ReactOS into the mixtoo.I just found out that master boot records are limited to 4 entries, meaning 4 primary partitions. I had Windows XP set up on my old drive as a boot partition, a program files partition and a media partition. Since I really didn't want to install XP from scratch, I cloned this setup on my new drive.
This leaves me one MBR partition entry for installing Windows 7, Ubuntu and ReactOS. I'd like to avoid having to install XP from scratch like the plague, partly because it's supposed to be a safety net in case things go wrong with my other OS's and because I've invested a lot of time getting it set up exactly the way I like it.Here are the options I've considered and why I don't like them:Install Windows 7 on my media partition. This would work, but I prefer to keep my media partition completely separate from any OS, so that I can reformat an OS partition without affecting my media partition at all.
Use wubi or something to install Ubuntu in the same partition as something else. Again, this is brittle.Move all my media to a logical drive on an extended partition. Create another logical drive on this extended partition for Ubuntu. The problem here is that extended partitions are rather brittle--if you nuke one, it renders the rest useless.Just put the old drive back in my computer and run XP off it. Use the new one for the other OS's. The problem here is that the old drive is slower and uses extra power, generates extra heat, etc.

I recently put ubuntu on my laptop in hope that most of my games would run through wine, some did and some didn't.
Anyway, long story short, I have ubuntu on my laptop and I want to re install windows onto a separate partition, keeping my ubuntu instillation in tact and set as my deafault OS.
I'm very new to ubuntu and the only guides i've seen are fairly complex. I was just wondering if anyone could point me in the right direction? p.s. Is there maybe a way to create an image of my current ubuntu nstillation/settings/apps etc. just in case I do something wrong and lose everything?

Where can I install grub? I know it can be installed to the mbr of a hard drive. I also know it can be installed to a /boot partition. Can I install it to a lvm partition? Does it have to be /boot? grub-install --root-directory=/boot /dev/hda Does this command install grub to a partition and link it to a separate /boot? I have fedora, but this is a live cd. I need to learn where I can install grub2 to boot

I've read several accounts of users who upgraded Ubuntu versions and ran into problems. I read that putting /home on a separate partition can make it easier to do upgrades. But it seems to me application versions and even the default applications themselves change so much between Ubuntu releases that I question whether it's a good idea to have all the "OLD" config files and settings that get stored in /home sitting around when running a new Ubuntu release.Does anyone think it's a better idea to just put the whole Ubuntu install (i.e., / and /home) on the same partition? And then when upgrading, backup, and then just fresh install everything (to get the cleanest possible installation)?

Looks like I missed defining a /home dir during installation. It's been a while I have a spare partition now that I'd really love to use. Can you specify this still, or is it only allowed during an install?

Fyi my debian installed on 1TB SATA disk, and I separate my /home partition from system what happen to my free space ? here is screenshot of my disk, using disk usage analyzer: is there is a way to get my space back or something missing on my setup.or I have to reinstall my debian and use LVM when partitioning my disk?

On my triple-boot PC:
Code:
SuLinux:~ # fdisk -l
Disk /dev/sda: 250.1 GB, 250059350016 bytes
255 heads, 63 sectors/track, 30401 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
[Code]....
Will the above procedure accomplish this objective, without crippling openSUSE ? The second swap partition has never shown any activity (on SUSE). I understand (from Using shared swap files) that a single swap partition may be shared. Since these areas are relatively small, It is not inconvenient to maintain separate swap partitions.

Recently I was working on something on my windows partition (on the same HD as opensuse), and all the sudden windows stopped working and I got some bad sectors on my HD.
Now, my opensuse installation is on the same HD as windows, but I need to get rid of that HD soon because it's starting to get worse (and I think opensuse is randomly crashing because of it).
Is there any way to transfer my opensuse parititon/os to another hard drive?

I'm a plain user of Open SUSE 10.2 for more than six months now on a dual boot machine (Vista Ultimate) and I'm 80% mostly on Linux now but because of my job I still have to keep windows.
My 1TB HDD is full and I've got a new 1TB HDD to add to my system. My plan is to leave this HDD only for Vista and to use the new HDD for Open Suse, changing it to the 10.3 version and without to lose my data and my settings (keeping the Home directory).
Considering that I am a ignorant could someone give me a step by step plan as much as detailed possible, in order to succeed?

We were trying to install w7 on a reserved partition. W7 did not like the partition (whatever we tried).
Since we had 3 hard-drives, on the allocated drive we deleted all partitions and set the partition table type new to MSDOS (yast etc.....).
W7 installed fine. We did not time it, but it appeared that 11.3 installs faster plus considering 11.3 installs quite a number of applications.
There are plenty of postings re integrating W7 to the Grub-menu.
This system went through several Suse updates, hardware upgrades, basically was all over the place.... we did a "new" install of 11.3 allocating its own hard-drive.
Install......fine, and Grub entered W7 to the menu. Worked ! Mounted the windows partition to /home/yourusername/windows
So, if you really (?) need W7 and have a spare hard-drive, this maybe is a clean solution.

I have Windows XP and OpenSuSE 11.1 installed on my laptop. I have recently removed the recovery partition provided by the laptop manufacturer (HP) to free up some space and ideally I would like to be able to add the free space to the existing Windows partition.The current partition set up is as follows:
Code:
Disk size 93Gb, P = Primary, L = Logical, U = Unallocated
P Windows XP 36Gb /dev/sda1 /windows

I was surprised not to find an existing thread on this anywhere, as I would expect this to be a common problem: I have the following partitions on my eee PC 100HE:
10GB Windows XP
5GB Linux Mint 8
5GB Ubuntu 9.10 NBR (awesome distro by the way!)
130GB Home partition shared by Linux Mint and Ubuntu NBR
2GB Swap partition shared by Linux Mint and Ubuntu NBR
I installed Ubuntu NBR after Mint. Immediately after install, the panel layout, menus and colour scheme were slightly messed up - presumeably because they had been "adopted" from the Mint settings in the home folder. I corrected them easily, but now I have the same problem in Mint. Is there any way I can get both distros to use the same /home folder, but different settings (i.e. the /home/username/. folders)? Can I get these settings folders put on a different partition for example?
And is this problem due only to the fact that these are 2 Ubuntu-based distros? Or will I have the same problem if/when I replace Mint with another distro, such as Fedora or Moblin?

From what I have understood, trying out different Linux distros is one of those things that a Linux user just needs to do now and again.
So what is the "best" way of keeping your home folder intact? Should I just copy the whole home folder to a separate storage space, install a new distro (I'm thinking going from Ubuntu to Suse) and then just past it in the newly installed distro? Or are there some other, more "refined" methods?
I thought one's home folder contains a lot of config and settings files, but they would surely just be applicable to the original distro!?
I know I can try out several distros via live CDs, which I have done, but when you've taken that next step and actually want to install another distro as your main Linux operating system.

Sometimes, (the most when I'm making changes in something, like the pager, appearance, theme, etc), the screen freezes completely (but mouse is moving) and I have to restart the system.
If I try it again, it crashes at the same point.

I am creating an openSUSE 11.2 Kiosk image. I have everything pretty much locked down but when I go into the gconf-editor under /apps/nautilius/preferences/show_desktop and uncheck the check box my mouse pointer changes to the circle icon that looks like it moves in a circle. Sortta like the busy or what it does during boot. Hard to describe by typing it out but if you make that change you'll see what I am talking about. I had this setup like this in previous versions of openSUSE so I am not sure what it is doing or what else I need to do to make the mouse pointer just the arrow like normally. I don't want the users to be able to right-click on the desktops to get a menu nor add icons so unchecking the show_desktop has served my needs.
