Ubuntu Installation :: Dual Boot Partitioning \ What File System Should Use For Windows Swap Partition
Sep 1, 2011I am about to get a new laptop here soon and I was planning a dual boot like I have on my current laptop (Win7 and Ubuntu), but I have something special in mind. I looked around the forum to see if there was anything like what I had or if it was even possible but I didn't see anything quite like this.I was wondering if this was even possible, and if so, would anyone be able to tell me what filesystem I should use for my windows swap partition?

May 5, 2010Saw 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.

View 9 Replies View RelatedUbuntu :: Swap Or Swap File On Flash Memory?
Aug 16, 2010RAM 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?

May 24, 2010I just got a new laptop and installed 11.1, and I want to move my swap file to a 8GB SD card I have. It seems to run very fast, so it will improve swapping speed. I created a swapfile with Partitioner, and I can delete the existing swapfile with GParted during a reboot - but I'm afraid I will make my system unbootable by doing that - don't I need to first tell OpenSuSE what swapfile (on the new sdb) to use? I'm pretty sure it will detect the new swapfile automatically during boot, but it might choke on a missing (old) swapfile.

Ubuntu :: Replace Partition With Swap File?
Nov 2, 2010I currently have Ubuntu Desktop 10.10 installed and have a great setup. However, I'm trying to install another OS on the hard drive and need to remove a partition. I've read online that I can remove the Swap partition and use a "Swap file". My question is this: Is it possible to replace the Swap partition with a "swap file" without having to re-install linux?

Ubuntu :: System Hangs On Boot Because Of Unmountable Swap Partition?
Apr 17, 2010So my Ubuntu 9.10 install has been hanging on boot lately. At first I thought it was a problem with the 2.6.31-20 kernel, because that is the default boot option in GRUB2. It seemed things worked fine if I instead chose the 2.6.31-19 kernel, but I had that hang yesterday too.I also had 2.6.31-20 boot just fine yesterday. Once. Next time I tried it - system hang.
What I mean by "hang" is,I would see the GRUB OS selection screen (I have 2 versions of Windows and 2 versions of Ubuntu on this machine),select the first choice (Ubuntu with the 2.6.31-20 kernel),see the "pulsating white Ubuntu logo" briefly,then a bunch of scrolling text, then...blank screen.Then nothing.I let it sit for a few minutes to a few hours when it did this, but nothing further happened.Then yesterday, I decided to let it sit the whole time I was at work, approximately 9 hours.I came home to a screen with the white Ubuntu logo and the following error message:
Code:
One or more of the mounts listed in /etc/fstab cannot yet be mounted:
swap: waiting for UUID=3fba81a3-de14-4f56-9e7b-ace95d933a0e
/proc/bus/usb: waiting for none[code]....
So it looks like I have a disk partition that refuses to mount sometimes.Gparted for some reason wouldn't tell me the UUIDs of swap partitions.They also don't show up in /dev/disk/by-uuid. Using the bootinfo script, I found out that 3fba81a3-de14-4f56-9e7b-ace95d933a0e is the 4 GB swap partition associated with my Ubuntu 9.10 install.The disk that partition is on is rated "healthy" by Disk Utility, with only a few bad sectors. The HDD is about 7 years old, so it's in remarkably good shape.What could cause this swap partition to not mount during boot, and how do I fix it?
Ubuntu :: Incorrect Swap Partition Size In System Monitor?
Jun 13, 2010I am using Kubuntu Amd64 Lucid on my desktop and I have allocated 08.03 GB partition for swap. But today I have noticed that system monitor is showing this as 09.90GB which is incorrect.
I tried deactivating the swap from KDE Partition manager. Even after deactivating swap it still shows the swap as 1.9 GB. So there is clearly 1.9 GB swap added to my system. I am not sure how. Attached screen shot clearly shows the system monitor issue. One possibility is, I have 4 GB (3.7 asper system) RAM comprising two units of 2 GB cards. Is this 1.9 GB read from one of these? I tried to boot the system from Kubuntu AMD64 live CD and then it showed only 8 GB as expected. So not sure whats causing this issue in my installation.

View 2 Replies View RelatedDebian Installation :: SSD - Garbage Collector And Swap Partition / File
Feb 27, 2015After some years using OS X, I'm returning on Debian on my Macbook Pro in single boot.
I've bought a Samsung SSD (850 EVO 500Go) in order to replace the slow built-in HDD.
But I've earned about the need of repartition of writing operation on that kind of drives, and I'm concerned about swap partition.
I need swap (especially for Darktable, browsers and maybe Steam games), but I wonder if the usual swap partition (even with discard mount option) is really recommandable for SSD drives.
Actually, on Debian wiki and others, the usual recommandation is "if you have enough RAM, don't use swap or minimise swapiness to 1", but using of swap file is not mentioned.
Indeed, if I have only one "big" partition on the SSD drive and TRIM activated, the garbage collector (low level) built in chipet's SSD will optimize SSD life, but I don't know how the low level garbage collection works with multiple partition.
So there is my questions :
- Will SSD garbage collection will preserve the disc use even if I have a 2GB swap partition ?
- Will I'd use a swap file instead of swap partition (I don't really need to hibernate) ?
CentOS 5 :: Need To Move Space From Root File System To Swap
Apr 7, 2009I currently have a server with the default VolGroup00 that contains logical volumes for the root file system and swap using logical volumes LogVol00 (root) and LogVol01 (swap.) I need to take space from LogVol00 and move it to LogVol01. I have found documentation for increasing the swap, and the resizing the logical volumes. However in the documentation and the man pages it says that I have to reduce the size of teh file system on the logical volume I am going to shrink. I have found documentation resizing the logical volumes but not the file systems.

OpenSUSE Install :: Swap Hard-drive From Old Laptop Into The New One?
Dec 30, 2009I got a new laptop, a Dell D400. I want to swap my hard-drive from my old laptop into the new one, and did so... but then got an error stating that my CPU didn't support PAE.
As far as I was aware I hadn't actually installed a kernel with PAE enabled [as I always pick a real-time kernel for audio work]: but then read that lots of the newer distibutions are enabling PAE by default [which is what's caused the problem].
Is there an easy way of disabling PAE in the existing kernel? Or would it be easier to downgrade to another version of OpenSUSE? I'm on 11.2.
OpenSUSE Install :: Can Swap Space Added After Boot Be Used?
Apr 15, 2010I found what I believe to be odd behavior on an OpenSuSE 11.0 computer today. I needed to add some disk space on one of our computers and here is what I did: This computer had a separate disk for swap space so I deactivated swap (swapoff -a) and then removed the swap entry from /etc/fstab. I then shut down the computer and replaced what was a single disk used only for swap with a RAID1 hardware mirror.
I then booted the system and added a swap partition and another file system on the new RAID1 volume. Even after activating the new swap space with swap on, no swap ever seems to be actually allocated. The swap space shows up in top, free, "swap -s" and vmstat, but never gets used. I realize that a reboot will result in the swap being used, but is there anyway to get the kernel to use the swap without a reboot.
It's probably worth noting that I verified this behavior on a second computer. That is I turned off swap, removed the swap entry in /etc/fstab and then rebooted. Swap is never actually allocated until a second reboot. By the way, this was discovered when some of our users attempted to run java on the system where I did the first work and they got:
prompt> java -version
Error occurred during initialization of VM
Could not reserve enough space for object heap
Could not create the Java virtual machine.
Yesterday, java was working fine and I got the same results on my test computer. Is this a kernel bug or just odd behavior?
OpenSUSE Install :: Maintain Separate Swap Partitions?
Sep 9, 2010On 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.

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?
Ubuntu :: Increase The _original_ Swap File's Size For Hibernate To Work - Wubi Install ?
Jun 8, 2010Wubi doesn't let me set the swap file size, so on installation it only creates a swap file of a few hundred megabytes. Because of this, i cannot hibernate my netbook (eeePC 1005HA), which has 2 GB of RAM.
Creating a 2 GB swap file alongside of the original one using the tutorial here did work, but hibernate doesn't seem to work with it. For this reason i thought increasing the original swap's size instead of creating more would be a way to solve my problem.
