General :: Swap Partition To The Back Of The Disk By Default?

Sep 8, 2011

As far as I know hard drives are faster at the beginning of the disk. If this is true, why does Ubuntu put the swap partition to the back of the disk by default?

Ubuntu :: Delete Snow Leopard Partition - Format Swap Disk Partition To Something Else

Feb 23, 2011

I had a drive with a partition layout like so:

~50gig Windows 7 - NTFS
~100gig Ubuntu - EXT3
~100gig Snow Leopard - HFS+
~100gig Extended Partition
-- ~100gig Swap Disk - exFat

I wanted to delete the Snow Leopard partition and format the Swap Disk partition to something else. exFat was causing major file size bloat on small files. QT sdk bloated to like 11 gigs or something ridiculous like that. Anyways, I loaded up an Ubuntu 10.04 LTS live cd and gparted then deleted the Snow Leopard partition. Gparted said "Mission Accomplished" and tried to rescan the drive, but never found it. At this point I restarted the computer, a dell laptop, which didn't boot with an unable to find a bootable device error. The ubuntu live cd doesn't see the drive anymore. gparted scans for drives indefinitely and fdisk -l has no output.

Security :: Encrypt Swap Disk Partition?

Apr 5, 2011

Is it better to use:

Code: -c aes-cbc-essiv -y -s 512 Or:
Code: -c aes-xts-plain -y -s 512

I've never encrypted a disk before; I'm following the Arch wiki (I'm a newbie, basically). Should I try and encrypt my swap partition (I've got 512 MB RAM, 1 GB swap)? Ideally, I'd like to make it so it's not feasible for someone (even a very skilled someone) to access my files (and system -- I'm encrypting /), but still make it fairly fast and usable for day-to-day operations. If it matters any, I'm using JFS.

Ubuntu Installation :: Moving System Partition - Back To Front Of The Disk

Jan 1, 2010

Currently, my disk layout is: 20GB(windows-ntfs) / 250GB data-ext4 / 20GB ubuntu-ext4 / 4gb swap

Since I no longer use windows, I want to move ubuntu to the first place.

What do I need to change in configuration files, grub and anywhere else?
Shoudl I keep swap where it is or move it, too?

Ubuntu Installation :: Partition By Default - How Much Disk Space A Non Manual Dual Boot Uses

Apr 23, 2010

how much disk space a non manual dual boot uses? I've always been guided by a person knowing much about linux when doing my dual boot (and been guided to do the partitions manualy), but this person is not there for the moment and I need to do a dual boot on my son's computer. Since he'll need his Windows computer mainly for games I wouldn't want Ubuntu to take 2/3 of his disk space (which is about 250 Gb I think, let's say 50 Gb would be perfect for the Ubuntu)

And I'm not sure how I could change this later, cause in my own computer I cannot find how to resize (I cannot unmount neither resize the partitions I have) I don't mean I need to do this on my computer but I mean I wouldn't want to try out anything if I'm not sure it be could restored in 1,2,3. And partitions is such a thing. If I remember correctly I've done dual boot by default (i mean without doing the partitions manualy) and it does about 50/50 ?

General :: Ubuntu - Change Swap Disk Priority Permanently?

Aug 8, 2010

I'm using two swap disks. Changing the order they are in in /etc/fstab and using "pri" in fstab doesn't have any effect. This is what it looks like /etc/fstab

#swap on other disk
UUID=90a1550c-84d6-4bde-8bc1-7c15292980f1 none swap sw,pri=-1 0 0
#swap on same disk
UUID=13b70e65-f1c3-4728-920f-9e92467d1df0 none swap sw,pri=-2 0 0

[Code]...

Its opposite of what it is in fstab, and changes to fstab have no effect.

General :: Where To Put My Swap Partition / Primary - Lvm?

Jan 11, 2011

I'm installing the ubuntu on my new computer with 1 TB hard drive (and core i7 870 with 4G RAM), for the purpose of scientific computing. I have two questions:

1. Since I am not absolutely certain that the simulation won't use larger swap space than usual (say 3x4G = 12G), I intend to set it initially as 12G keeping in mind that I might have to extend it later. So one might suggest putting it on lvm partition. But then I read that I can maximize the speed if I put the swap at the outer track. If I mix it with the other logical volumes in the same volume group, then I don't know where my swap space is across my hard drive, isn't it? So this might suggest I make it as a primary partition. I'm stuck..

2. My current planned partition map is
/ 1G
/tmp 10G
/usr 20G
/var 5G
/home the rest

taking into account I will install MATLAB and maybe other visualization software. What do you think of this scheme?

General :: How To Reinstall Deleted Swap Partition

Jul 4, 2010

I had to delete my swap partition in order to reinstall win XP, but now I need to reinstall it. I run Ubuntu 10.04 and read that there is a command $ sudo mkswap /dev/sda1. I have about 19 GB of free unpartitioned space left on the hardrive that I want to make into a swap partition. I'm not sure whether I should use sda1 or if the book uses it as an example and if I use it it could wipe away my existing partition with ubuntu installed on it.

General :: Swap Partition UUID Changed - What To Do

Jun 5, 2010

Someone (not me) recently installed some new distros on my HD. It seems that during the installation my swap partition was reformatted and a new UUID was assigned to it. I have the following questions:

1. I know that I have to change the swap partition UUID in /etc/fstab and /boot/grub/menu.lst of the affected distros. Is there anything else that needs to be changed?
2. I presume a similar change has to be made to the Grub 2 configuration, for those distros that use Grub 2. I have no experience using Grub 2 so how do I make the change or where can I find instructions to do it?

General :: Windows 7 Disk Management Utility Doesn't Show Disk With Ext3 Partition

Oct 10, 2010

I have a 2 TB disk in an external SATA dock, formatted with a single ext3 (Linux) partition, which doesn't show up in the Windows 7 Computer Management->Disk Management utility, even as a raw/blank disk. I've verified that there's nothing wrong with the disk by connecting it to my Linux machine and mounting it, and I've verified that the dock is functioning properly by connecting a different FAT32-formatted disk, which mounts flawlessly as expected.I realize that I can't actually read the ext3 partition without additional software (e.g., Ext3IFS), but why doesn't the disk show up at all? Is there some sort of stupid anti-Linux filter built in? Is there any way to force Windows to recognize the disk, so that I can at the very least use direct block access with it?

Background: I want to clone an identical 2 TB disk onto this one. Due to my hardware layout, it's much easier to have the source disk attached to one machine and the destination disk connected to another, and do the clone over the network (the network is not a bottleneck with switched gigabit ethernet), than it is to hook them both up to one machine.(1) I did this once before when both machines were running Linux, but I've since upgraded the destination machine and decided to switch back to Windows for regular desktop use. I've got Cygwin installed, and have verified that the same basic method (dd + nc) will work, but I can't do anything if Windows doesn't even consider the destination disk to exist.I only have one eSATA port on each machine. Opening them up just to do this clone is a rather large annoyance. Also, since this is my backup disk, I'd like to eventually automate the cloning from the active disk to another one that I regularly swap with a third disk that I store off-site.

General :: Creation Of Swap Partition During Ubuntu 9.10 Installation

Mar 26, 2010

When I do a "clean" install of Ubuntu 9.10, Step 5 of 7 is when you choose how to partition your hard drive. My Acer Aspire Desktop has 8GB of RAM and a single 160GB SATA hard drive. If I choose to let Ubuntu do the partitioning, only three partitions are created and one of them IS a Swap partition. However, if I choose the second option to manually create my own partition tables, there is NO Swap option listed in the drop-down list of partitions to create!! Why in the world not, considering the importance of this partition and the fact that the first option DOES automatically create it? A second related (I think) is about the Live System Rescue CD and GParted 4.9. When do you use either of these utilities? After all, GParted is included System Rescue CD.

So, if I want and choose to do a manual/advanced partitioning of my hdd, the only time I can see using either utility is after the complete installation of the Ubuntu distro. Yet, choosing to manually partition my hard drive always results in an error or warning message that I haven't created a Swap partition before proceeding to Step 6 of the installation. Well, of course not since the choice isn't even possible. Good grief, what am I supposed to do when I arrive at the step where I am supposed to choose and then create the partitions for my hdd? Choose the first option, which I don't think is wise/good at all, especially with security in mind. Or choose the second option of using a program like GParted at all? It is hard enough for me to choose a partitioning scheme at all, since opinions on how many partitions are needed and what sizes they should be.

General :: Ubuntu 64 And Backtrack Won't Share A Swap Partition / Fix It?

Nov 4, 2010

I'm triple booting Windows 7 32-bit (that's the only version I had), Ubuntu 10.10 64-bit, and Backtrack 4 R1.

Windows 7 installed and runs fine. Ubuntu installed and runs fine. I try to install Backtrack 4 R1, create a / partition, create a /boot partition (do I need to create a /boot for Backtrack?), and I don't create a swap file because the Ubuntu swap file is already in there.

I click "forward", the install starts up, then I get "The attempt to mount a file system with type swap...yadda yadda yadda...has failed." I google this, I get some results talking about an mkswap command, but in my noobness, I don't understand.

Can Ubuntu 64 bit and Backtrack not share a swap file? I don't want to create 2 swap files because I've googled around and that looks like a bad thing to do.
