Ubuntu :: 11.04 Installation Creates Three Linux-swap Partitions
Sep 1, 2011
I have installed Ubuntu 11.04 for a friend on his new laptop. First I shrunk his Windows partition and then installed Ubuntu 11.04 direct from the Live-CD. Everything worked perfectly and he is very pleased. However I noticed one strange thing. When I ran GParted on the installed Ubuntu Desktop I noted that Ubuntu was installed on an extended partition, /dev/sda4, with the ext4 root file system on /dev/sda7 and three linux swap partitions each of 7.85 GiB. Only one of these swaps partitions is "on", ie with a key next to it. The other two seem to be just wasted space. Why did the install partition three swap spaces?
On a similar theme, on my own machine I installed 11.04 next to my 10.04. This time it installed two additional swap spaces (see problem above). I removed them both and altered the fstab to the UUID of the existing 10.04 swap space and it works perfectly. So my second question is why doesn't the install use existing swap spaces rather than creating new one(s)?
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?
I am using my flashdrive to install. I allocated 200gb for window 7 ult and used partition magic to format the rest to ext3 and swap for DISK 1. But when I try to install Ubuntu, installation can't seem to find the ext3 or the swap. It only sees my other drive in RAID 1.
My harddrive setup Disk 1(RAID ready) NTFS 100 mb - System NTFS 195.21 GB EXT3 253.88 Linux Swap 16.46 GB DISK 2 (RAID 1) NTFS931.31
I'm looking for an app for Linux that creates bootable images. Back when I used windows, I used Imgburn. Now, I need an app like that for Linux. Wherever I looked online, I saw either one (or both) of these ideas.
1. Run Imgburn under wine 2. Get k3b
I don't like using wine because the programs run very slow. I'm not sure exactly how to get k3b to produce a bootable image. So that's where I'm stuck.
I was trying to install Ubuntu as a dual-boot on my Windows Vista laptop. The hard drive is 250 gb: Vista boot 157 gb partition; a partially-occupied 33 gb partition which was designated as swap-space; a newly partitioned and ext3 formatted 30gb for the Ubuntu installation. I believe there is also a hidden partition ~20 gb with "hidden" system info. During installation I received an error message concerning the swap space partition, which forced me out of the installation and back to the ubuntu partition manager screen. Now in Vista my 33 and 30 gb partitions are missing. Is there anyway I can get back to pre-Ubuntu state?
Can I delete the ext and swap partitions from disk management on windows 7 ? Because I want to install a fresh new copy of ubuntu 10.10 . I know it would affect windows 7 boot up.I can handle it by system restore Anyway can I do it or not ?
I have Windows 10 and Deb 8 dual boot, and I need to re-install Windows but want to avoid (or at least plan for) losing Grub/Linux boot.
Last time I re-installed Windows after Linux I ended up having to re-install Linux again afterwards as well, because I couldn't recover it (seemingly due to complications from encryption). So this time I'm wanting to plan and avoid that.
CURRENT DISK PARTITIONS:
Code: Select allsda1 | 550M | EFI System sda2 | 128M | Microsoft reserved sda3 | 175.8G | Microsoft basic data sda4 | 286M | Linux filesystem (Boot) sda5 | 28.2G | Linux filesystem (Root) sda6 | 91.3G | Linux filesystem (Home) sda7 | 1.9G | Linux swap
[Code] ....
As there is a "Microsoft Reserved" partition and a separate Microsoft directory within the EFI partition, if I just go ahead and reinstall Windows will it install it's boot loader/image to one of it's own partitions? And NOT affect anything else like Grub and other Linux things?
Logic tells me yes, but there seems to be many issues on the internet about installing Windows after Linux.
My primary concern is whatever happens with Windows or anything to do with dual loading etc, is that Linux will still just boot, or I can get it working again without much hassle.
Why is there a reserved Microsoft partition AND a Microsoft directory in the EFI partition? Which one boots Windows?
Why is there a separate Linux Boot partition AND a Linux directory in the EFI partition? Which one boots Linux? Where is Grub invoked from, is one redundant, etc?
How these work. It is possible I've set them up wrong, or with redundant partitions, but both systems have been booting ok for months.
I have a dual boot on my laptop between XP and Ubuntu with a storage partition.that gives me total of 4 primary partition
-Windows -Storage -Ubuntu -Swap
I now want to add a OSX to my laptop in tripple booth. I did shrink the windows partition and now I realized that all my partitions are primary and cannot create a new one with the space I shrink from windows.Is it possible to merge ubuntu and its swap into extended/logical partitions so I can create a new primary for Mac OS X?
Unitl yesterday I have a pc with ubuntu server and desktop. Server I installed first. Desktop later. But I want to remove that server and use the space for other stuff..I mess with Disk Utilities and gParted and remove the ubuntu server partition. But now my grub2 stops working. How can I restore grub2 on the desktop partition and use the unallocated space for desktop without loosing any of my stuff? I have a scanner, webserver running, samba and other apps up and running on desktop.I can boot via live cd, and I get this on sudo fdisk -l:sudo fdisk -l
Disk /dev/sda: 80.0 GB, 80000000000 bytes 255 heads, 63 sectors/track, 9726 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes
On my only hard drive, I have it partitioned for Windows 7 and Ubuntu 11, Earlier today I performed "Shrink Volume" on the Windows partition, successful, opened 22.74GiB I would like to increase my 10GiB Ubuntu 11 Partition to 16GiB, then create a partition for trying out chromium. I know the following discussion I am going to sound like a noob but for simplicity bear with me. When I say "left" I actually mean tracks closest to the center of the cylinder and right, those further away.
sda1 and sda2 are my Windows 7 Partitions, Then I have 22.75GiB of unallocated space from the shrink volume, then sda3 extended, sda5 swap, and sda6 ext4 /. How do I "slide" the swap and Ubuntu 11 ext partitions to the left while maintaining their contents? Am I just as well backing up, then formatting the Ubuntu 11 partition? My first thought was to ghost the Ubuntu partition to the unallocated space then updating grub, but grub did not see it. The following is a screenshot of gparted's view of my HD.
I have an CentOS 5.4 install with several swap partitions of 2048Mb each (someone suggested to me the OS would run better like this?). But, I have a few other partitions and I'm sick of having so many to check and monitor. Also, having set up another machine with only one swap partition, I am not finding it running any better/faster.How do I go about deleting all the swap partitions and making a new one (to fill the exact same space as ALL of the old ones)?
I have got 2 disks available and would like to create 3 main partitions: one for file system (maverick), one for home folder and one for linux swap.
I read many howtos and now I feel more confused!
I would like to obtain the more efficient solution in order of speed (performance): as far as I can understand (not so far) .. it seems that the best choice is:
Quote:
disk 1: [beginning] ubuntu | home | others [end] disk 2: [beginning] swap | others [end]
My situation now is, according to guides I read before:
Quote:
disk 1: [beginning] ubuntu | others [end] disk 2: [beginning] home | others | swap [end]
now .. before moving all my staff ..
I thought to have understood that ubuntu use swap only for hibernation / suspend activities, and therefore it's recommendable to put the system at the beginning of one disk, and the home folder at the beginning of a second disk in order to have quickly two disk reading / writing on the right position without moving too much and spend time.
But now I'm confused because it seems that ubuntu DOES use swap for normal activity (and so it's better to put it) at the beginning of a second disk.
I always saw my swap next to zero during my activities .. is ubuntu using swap like windows with pagefile.sys?
I have two disks, sda and sdb. Each has a partition that is part of a mdraid array for /. Each one also has a swap partition, and both are used by linux. I've heard that hibernation won't work with two swap partitions. Is there any workaround, other than only using one swap partition?
I've installed some Linux distributions over the past few weeks, and I've recently noticed that previous installations of Linux have left my hard drive cluttered with numerous 4 GB swap partitions. I've since deleted them, but is there any way to avoid this a priori in the future?
I'm a "new" Linux user, have been using Ubuntu for the last year with no problem but I decided to try out a different distribution to get more experience. So I decided to go with openSUSE (which I have been using on a VirtualMachine back at work). I have download the ISO, created an liveUSB (because my laptop dvd isn't working properly) and wanted to install openSUSE on the hard drive partition where currently Ubuntu is. So, I suppose that in order to do this I should choose the option "Import mount points" and select the Linux partitions (drive and swap) and that would be it.
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.
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?
I have a RHEL4 system with 2 250GB physical volumes. There is a boot partition that is outside LVM and 2 logical volumes (swap and root) within a single volume group. This volume group bridges the 2 physical volumes.
I would like to clone this system onto a single 1 TB physical volume that will replace the 2x250GB currently in use.
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
I have 3 Ubuntu installations & a PCLINUXOS, plus Windows XP installed on one hard disk. I still can boot to each one of them and can mount each one using Ubuntu.
The problem "may" have occurred when I reduced the size of some linux partitions using gparted. I still have plenty of space in each of those partitions.
When I started gparted all of the HD was unallocated. I did that from each ubuntu installation and the PCLINUX installation, plus LIVECDs. All indicated the space was unallocated.
When I did an fdisk -l from a Puppy Linux LiveCD I got a normal start and ends of each partition.
When I tried it from Ubuntu installation or live cd, I received the following types of responses:
Code: ubuntu@ubuntu:~$ sudo fdisk -l /dev/sda5
Disk /dev/sda5: 28.5 GB, 28566397440 bytes 255 heads, 63 sectors/track, 3473 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x00000000 Device Boot Start End Blocks Id System ubuntu@ubuntu:~$ sudo fdisk -u /dev/sda5
The number of cylinders for this disk is set to 3473.There is nothing wrong with that, but this is larger than 1024,and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO) 2) booting and partitioning software from other OSs (e.g., DOS FDISK, OS/2 FDISK) Plus the Windows partition seems to go over its limits.
Since all of my OS installations are still working, I don't know how critical this is. From reading another post, I understand this might be able to be fixed by making some changes in fstab.
Lucid on an Acer Travelmate800.Can anyone tell me why I have 0k for swap space? I allocated swap which I can see in my Disk Utility's 'volumes' display.
RAM for older machines like I use is fairly cheap these days. But flash memory is just as cheap or cheaper. So I'd like to ask about the feasibility of expanding my system's memory using flash memory. And about whether creating a partition for swap on the flash memory, or whether a swap file on the flash device, is the better way to go.
By flash memory I have in mind mainly USB sticks or what are sometimes called "pen drives." But I do also have CF and SD cards that, with the proper cheap adapter (one of which I already own for adapting CF) could be used to create extra swap space. So, what is the current consensus on the feasibility/advisability of using flash memory for swap? I've read about the limited write cycles of flash being an argument against using it for swap. But recent reading indicates to me that the limited write cycles problem applies mostly to older, smaller-capacity flash memory. Some will come out and say that, for larger-capacity flash memory, the life of the device is likely to exceed the amount of time your current computer will be useful (I think I've seen estimates in the range of 3-4 years life--minimum--for newer, higher-capacity flash memory).
A more persuasive argument I've heard against using flash memory for swap is that access times for these devices can be much slower than SATA, and maybe even IDE, hard drives. That would certainly dictate against using flash memory for swap.
So, how about some input on this issue? Anyone using flash memory for swap? If so, what kind (e.g., usb stick or SD/CF)? Are you using a swap file or a swap partition? How's system performance? Likewise, has anyone had flash-memory-used-as-swap die on them? The consequences would undoubtedly be dire. Also, has anyone measured flash memory access times to confirm or refute claims about slow access times? Are some types of flash memory better/worse than others in terms of access times?
I'm trying to do a network installation of opensuse 11.2 on my ASUS eee 701.
- I've downloaded the ISO image, verified it with md5sum, and burned it to CD. - I've used a live CD and fdisk to create a new partition table on the internal SSD (/dev/sda) and a single primary partition of type 83. - I've booted the CD, changed the language to English[UK], and continued.
The installer then told me that there's not enough memory for a graphical installation. This is weird because my ASUS has 1MB of memory and works fine with a live CD, but it's not much of a problem because I'm comfortable with text-based installation.
The real problem is that the installer froze on the next screen while "searching for Linux partitions". I aborted after about 10 minutes of inactivity.
I don't really want to download the entire DVD because I've only got 4GB of SSD and want to set up a trimmed-down system.
I had a problem with the install of Ubuntu 10.04 and 10.04.1 on a Dell Precision T3500. I used the 32bit live CD. I let the installer create the file systems and use the whole disc. The disc is was created as shown below. After the install button was pressed, the root file system was created and then the swap. When the installer went to mount the swap it complained there was not enough memory and failed the installation. I installed Ubuntu by manually making the swap file system smaller using gparted and assigning the / and swap to the file systems created by gparted.
