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?
View 12 RepliesI 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?

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)?

- 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.
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

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 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?

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.
Is there a command that tells you what the partitions are fdisk -l shows partitions I want to know which is root swap home etc, Labels the partitions?

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 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'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.
View 2 Replies View RelatedI 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?

I am not familiar with LVM at all, although I have successfully got it up and running in Slackware. What I would like to know is, could I create one Volume Group in a Physical Volume consisting at the moment of just one disk, and install separate Linux releases into Logical Volumes in this solitary VG? So, for example:
/dev/sda1 = Physical Volume
volgroup = Volume Group

View 1 Replies View RelatedRAM 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've noticed in the last few weeks that whenever I open a PDF file in Adobe Acrobat Reader I get several files with names like 4cbe92d509fde in my /tmp directory. This happens for all PDFs, whether I download them or create them myself. Has anyone else seen this happen? It's not a big deal, since I can just rm those files. I'm just curious about how this happens, and if there's a way to stop it. I'm using Acrobat Reader 9.3.2 in F13 (32-bit).
