Ubuntu :: What's The Best Way To Remove Swap Partition
Feb 6, 2010I want to remove my swap partition. Probably one I would have to boot into a rescue cd and remove it, but aside from that is there any other consideration or commands that I need to be aware of?

Ubuntu :: Delete Snow Leopard Partition - Format Swap Disk Partition To Something Else
Feb 23, 2011I 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.
Hardware :: Invalid Partition Table For Swap Partition That Moved With Gparted?
Feb 8, 2010I was reading another thread about someone with a bad partition table and I decided to join this forum. I'm not going to take any drastic actions with the partition (/dev/sda3) in question. I am going to wait for instructions on what to do first. I am not very good with Linux and need some hand holding. System: DELL 4550 Dual-Booted with XP and Ubuntu. Works OK, just no swap. Well, here's what I did: I deleted a partition for Windows XP Pro because it was a trial, and it ran out. I then decided to slide the swap partition for the Ubuntu Linux that I dual-boot into over. (If this was successful, I was going to try expanding the root partition to take up the unused space.) I used Gparted on a CD to do this, as I figured it was safe to do.
I now cannot mount the swap space at bootup (and have to go into a backup version of the OS), although I can use Gparted in Linux to execute the "swapon" command, and it appears that it worked because I now see "swapoff" as an option on the context menu. (I actually don't even need a swap partition, except to hibernate.) If I highlight the swap partition and click on "Drive" on Gparted's menu bar and select "Create Partition Table", it will erase all data on /dev/sda, so how do I fix the bad partition table non-destructively?
General :: Determine Number Of Blocks For A Partition?
Jul 1, 2010Can someone explain how to determine the number of blocks to determine the number of cylinders for a new partition on hard drive.
Why is block size divided by 1024?
I think I understand unit size is the total bytes per cylinder, I get that. I understand the anatomy of the hard drive (i.e. heads, sectors, cylinders.
My problem is, if I need to calculate the number of cylinders needed for let's say a 20G partition on a 120G drive.
Debian Installation :: Wiped Windows Partition With Swap And LVM Partition
Jan 17, 2015I am having issues with Grub 2 after installing Debian 7.8.0.The computer is a HP Pavilion 500-307nb. I made the original harddrive /dev/sdb and inserted a Samsung Evo 840 as /dev/sda. From the original hard drive (/dev/sdb), I wiped the windows partition, but left all other partitions unchanged (in case I would ever want to recover the desktop to its original state). I replaced the wiped windows partition with a swap partition and an LVM partition.These are my hard drive partitions:
/dev/sda (Samsung Evo 840)
Number Start End Size File system Name Flags
1 1049kB 3146kB 2097kB primary bios_grub
2 3146kB 944MB 941MB ext4 boot
3 944MB 94.4GB 93.4GB host lvm
4 94.4GB 1000GB 906GB guests lvm
[code]....
The partition /dev/sda3 has 2 logical volumes with filesystem ext4 that I mount to / and /home.The partition /dev/sda2 is mounted to /boot..When I install like this, Debian installs fine, however Grub2 is not installed correctly.Debian installs grub-pc which seems not able to boot the gpt partition. So I boot the Debian CD in rescue mode and execute:
mount /dev/sda2 /boot
aptitude purge grub-pc
aptitude -y install grub-efi
After rebooting, I come in the grub rescue shell, which says: error: no such device: 986f2176--4a4b-4222-83b9-8636a034b3c7.
When I then enter in the grub rescue shell:
set boot=(hd0,gpt2)
set prefix=(hd0,gpt2)/grub
insmod normal
normal
Grub and Debian start up correctly.why can Grub not start up automatically correctly? Where does the UUID 986f2176--4a4b-4222-83b9-8636a034b3c7 come from? I have reinstalled Grub several times, I have reinstall Debian several times, I have even wiped all partitions from /dev/sda and recreated a new gpt table with parted and manually set the partitions in parted. Still on each reinstallation, Grub fails because it cannot find exactly the same UUID. Since this UUID is always the same, it must be stored somewhere, but it cannot be the partitions, I have wiped them and the partition table several times.
I did though a firmware update of the Samsung Evo 840 before reinstallation, could this be a cause?Also the problem is not in grub.cfg. Grub starts correctly if I enter the commands above in the grub rescue screen and the UUID value does not appear there.

If not, what is the recommended way to check for bad blocks on the root partition? I would like to avoid having to create a rescue disk and boot off of it.

May 21, 2011I've recently just installed ubuntu 11.04 but seem to have made a big mistake. During the install process I was asked to specify a location to be used for swap.

Is there anyway for me to access it? or to at least recover the information I need from there? its about a 200gig partition, and it used to be ntfs.

Jul 6, 2011I have a rel 5.6 system that we just added more memory to.
1. What is the correct or best way to increase swap?
2. Can I remove the swap space later on?
3. How do you remove it when done?
Our rootvg only has 8G available to it and I want to be sure if i allocate anything out to it I can reclaim when done without having to rebuild the system.
We have to do a lot of data moves so we allocated extra memory to this VM system and now we need to increase swap. I did see several articles in google but they describe using a new swap partition, a swap file and increasing an existing swap space. I am still not sure what is the best way to go knowing this is a temp situation.

Jul 27, 2009I have a brand new thinkpad X301 with 4GB of RAM and thinking of getting fedora 11 on it. The plan is to have it triple boot with vista/seven and hopefully OSx86. I am aware of the 4 primary partitions limit on an MBR disk. I was thinking of having a swap file instead of swap partition and not creating a boot partition as well. If I install the boot loader(GRUB?) on the root partition will I be able to boot it without any problems by using vista's boot loader?
Or Maybe I should install GRUB on the MBR and add all the other operating systems on it? Does anyone have any objections for not creating a swap partition or a boot partition? When comes to desktop environment I've been using KDE in the past, is there any major advantage of using Gnome over it? KDE seems to look really nice on fedora where Gnome is maybe more stable?
Ubuntu :: No Swap Partition?
Feb 14, 2011My motherboard supports up to 8GB DDR2. I currently have 4GB installed. If I maxed out my RAM, and installed 10.10 without a swap partition, I've heard this would increase speeds significantly. Would it? This particular rig runs multiple servers including an Asterisk PBX with FreePBX, XBMC, and Boxee. XBMC and Boxee do not run at the same time, only one at a time. Would it be safe to run with 8GB ram, and no swap partition? Running FreePBX/asterisk, XBMC, playing videos or ....., and every other background processes, free shows on average 50% free. Opinions?

Jul 3, 2011Currently my system runs on two disks, sda 30GB and sdc 1GB. sdb is my data disk. I have set the partitions as sda1 /boot, sda2 /(root) and sdc1 /(swap).
Thinking that sdc was udma33 i used the disk for a swap area. Later i found out that it is pio4 and i want to relocate my swap area to sda.
Using GParted Live i am planning to create a swap partition to sda. Will fixing the entry in fstab be enough to correct this or do i need to do something more?
I could also use some advice on which live debian image i can install in sdc, to use for rescuing purposes. The capacity of the disk is 1080MB.
As a side note, the images i find for usd-hdd are direct download. Are there any torrent files for these?

Fedora :: F15 - Swap Partition Not Mounting?
May 31, 2011I have the swap partition configured normally in fstab but it doesn't automount when I boot up. Not only that but I can't manually mount it either (ie with 'swapon -a', 'swapon -L /dev/sda7' etc). When I try I get this error -
Code:

The swap partition is used by another installation (Ubuntu dual-boot), which mounts it fine each boot.

View 9 Replies View RelatedUbuntu Servers :: The Swap Partition Is Not Being Used
Apr 19, 2010I recently installed Ubuntu Server, the 8.04LTS release, on my dad's computer which, for the time being, has to dual-act as both a server and a desktop. Will be running solely as a server pretty soon, though. Anyway - since I was down on the budget and the project I put up the server for is still in a development phase and not worth to invest serious money in (at this stage), it has to run on a computer with the following hardware configuration (I left out the non-important parts):
Code:
Intel Celeron 2.2 Ghz
~500 MB of DDR 333MHz RAM
It has 80 or so GBs of disk space, so I went for the low-mem, high-disk scenario and created a swap partition of 1,5 GB. However, I can notice that is rarely even used! I have set the vm.swappiness parameter to 95 but my swap partition is still not being used, even when the memory usage goes up to 90%. I saw it being used once, but only when the needed memory size exceeded 500.
Does anybody know how to force Ubuntu Server to use the swap partition?

View 9 Replies View RelatedUbuntu :: Add A Swap Partition To Lubuntu?
Jan 19, 2011I have a live/persistent installs of Lubuntu 10.04 on a USB-HDD. It's on a 320 GB portable drive. I've partitioned it so that 80 GB is for the Lubuntu live install and the remaining 240 GB is another partition dedicated to storing stuff. So this USB-HDD is doing double duty. The thing is, I was paying so much attention to making the persistent install work without making a mess of the boot loader (I did that in the past; twice!) that I had overlooked the fact my live install does not have a swap sartition on it. I just assumed (incorrectly) that the swap partition on would just be part and parcel of the installation. Can anyone tell me of a way to add a swap partition to each of my live installs? Without losing any data or anything like that. It's probably not doing any harm not having a swap partition, but I'm assuming that my live install would be that much more efficient with it.
View 7 Replies View RelatedUbuntu Servers :: Swap Partition Does Not Get Used
Feb 15, 2011After unsuccessfully trying to install Oracle Express I find that for some reason the swap partition on my server disk does not get used.
My setup: 10.10 server x64 on an intel server with two 500gb HDs in a mirror array
This is puzzling, because I definitely created a swap partition for this system and indeed if I look at /etc/fstab I actually have two swap partitions, one on /dev/mapper/[some long raid name]_ar05 and one on /dev/mapper/cryptswap1, but AFAIK this is normal with 10.10.
"swapon -a" fails with this message:
Code:
swapon: /dev/mapper/[raid name]_ar05: read swap header failed: Invalid argument
swapon: /dev/mapper/cryptswap1: stat failed: No such file or directory
there's always the option of using a file on the server's filesystem, but I want to see if this can be fixed. I only have remote access to server via SSH, which makes startup troubleshooting pretty impossible.
I have a local server at home also using 10.10 server 64-bit with an encrypted swap file running on a RAID array, but it does not have this problem.
