General :: How To Reinstall Deleted Swap Partition
Jul 4, 2010I 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.

View 14 Replies View RelatedDebian 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.
Fedora Installation :: Installation - Creating A Swap Partition Or A Boot Partition?
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?

View 4 Replies View RelatedUbuntu Installation :: Using FAT32 Partition As Swap?
Apr 5, 2010I'm installing a new SSD this upcoming weekend. My thought was to go easy on it so it lasts longer by putting my swap files on a mechanical drive instead of the SSD. I don't - however - want to waste space for swap files. It would be nice if I could use the same 6GB FAT32 partition for swap files for both Windows 7 and Ubuntu. Is this possible? It might not even be necessary though, I have enough RAM that I rarely use the swap file at all (I've even considered going without swap all together), so it probably won't pose a huge load to the drive.

View 1 Replies View RelatedUbuntu Installation :: Add Swap Partition Without Reinstallation
Apr 9, 2011I'm using ubuntu 10.04 and it seems that I forgot to set up a swap partition when I installed my system. So, I can't install hibernate, and I don't think I have any virtual memory any more.
I know that I can always set up a swap file to play the same role, but since swap file is not contiguously stored on hard disk, the performance is expected to be worse than a swap partition.
So, how can I add a swap partition and make my system boot with it every time from now on? I have unused space on my hard disk, and re-installation is NOT an option.
Ubuntu Installation :: Does Swap Space Need It's Own Partition?
Aug 9, 2011I am using a Dell Inspiron 580 that I recently recieved as a gift. I wouldn't normally purchase a Dell, but I have no money and it my old computer was WAY past it's prime. After going through a miniature nightmare I now wonder how to create swap space for my ubuntu installation. I am running 10.04, 64 bit. I am having no problems, but I have no swap space. My computer is a new -Intel i3- with 6GB of ram; so I assumed I could worry about getting it installed, then set a swap file later. As I said, it runs well, but i don't feel comfortable with ZERO swap space.
When I installed Ubuntu I already had a problem because Dell had included 2 special partitions that are diagnostic and recovery. This didn't surprise me, but I want to make my system backup less than 100GB, so I shrank the "c:" partition to 100Gb and made the free space "storage":NTFS partition. After backing everything up (before messing with the partitions), I installed Ubuntu. Since I had created the backup that Dell asked me to (the very first time I turned the PC on) as well as my own system image I wasn't concerned.
Using GParted Boot disk I deleted the Dell "Recovery" partition and marked the "C:" drive (COS)) as active. I used a Windows 7 install disk to "repair" the bootmgr problem. Had to run "repair" twice, but it worked.
My question now is: why didn't Ubuntu installation say anything about a swap partition until I had already set up my partitions? I could easily give up a gig or two for swap space but I cannot make a swap partition unless I delete the Dell diagnostic partition (NOT the "recovery" partition; the other hidden one). I don't mind deleting the "recovery" partition because it is backed up, but I would prefer not to delete the "diagnostic/utility" partition, just in case. The 40MB is crap anyway.
It hadn't occurred to me that I would have trouble making swap space. I am used to windows (I am dual booting with GRUB BTW, if that matters) and the swap FILE doesn't need it's own partition. I understand why a separate partition would be better, but unless I can somehow create a logical/extended partition for swap, I need to know what else I can do.
I believe Ubuntu is a better system for many reasons, but little things like this do puzzle me. I am no engineer, or software designer, but I don't understand why I wasn't given an option, such as: You cannot make another primary partition; would you like to use a virtual disk/file as your swap space?"

View 3 Replies View RelatedGeneral :: Creation Of Swap Partition During Ubuntu 9.10 Installation
Mar 26, 2010When 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.
Ubuntu Installation :: Testdisk Can't Restore The Partition - Just Deleted
Aug 8, 2010I tried to install Ubuntu next to XP. After restart - no XP and no Ubuntu. Something wrong with loader I guess, I see command line prompt (of the loader I guess).
So I restarted from liveCD. But no "Repair Install" option like in XP CD. So, I deleted partition to install again on top of old, then learned a loader possibly could be fixed.
So, the problem is: testdisk cannot restore partition I deleted. I didn't write on disk anything. May be swap space after couple reloads from liveCD corrupted it?
It complains "The harddisk (...) seems to small!", it sees some other partitions and doesn't see what Gparted and Disk Utility.
Let me know the best approach to get back XP running (having Ubuntu would be good too).
Here below are the screen captures for details.
Quich Search results. Can't recover what's found. Why 4 partitions are found? Notice, "The harddisk seems too small !" Could this be a problem? HDD is not Maxtor anymore
The gap is there but no deleted partition shown
Essentially same thing... going for deeper search
Deep Search hasn't recover anything new. And shows same results as Quick Search (2nd testdisc image )Hit "continue"...
Now the partitions shown as deleted because of overlapping. The partition to be recovered is still not in the list.
Anyway, my final goal is to get WinXP back and if possible, install Ubuntu. It's nice that installer still sees the XP. Too bad the loader doesn't. how to get it done.
Unlike during installation of XP, ubuntu doesn't offer to utilize the deleted partition. Is it going to stay empty/unallocated? Forget the empty space, will I get XP running if I continue and install?

Debian Installation :: How To Find Out If Swap Partition Is Active
Feb 12, 2015I recently installed Debian 7.6 64-bit on Dell Vostro 1520 laptop.Using Gparted, create extended partition in the remaining disk space 67.91 GB
Install Debian 7.6 as follows
Code: Select all/dev/sdb5 / 8GB Ext4
/dev/sdb6 / home 17GB Ext4
/dev/sdb7 swap 5GB
I opened a terminal and ran some commands to show the results below....
Code: Select allroot@DELL-DEBIAN:/home/hugh# cat /proc/swaps
Filename Type Size Used Priority
/dev/sda7 partition 4979708 0 -1

I have a couple of questions....
1. Does the data above indicate everything is running as it should?
2. What does this command tell me about swap? "/sbin/swapoff /dev/sda7" I read somewhere it should be run on 64-bit system but not sure what it does.
3. Is the command "cat /proc/swaps" the best way to determine if swap is running ok?
4. Can I share this swap partition with another distro, e.g. Ubuntu or Xubuntu? as I would like to multi-boot for testing purposes.

View 6 Replies View RelatedUbuntu Installation :: Accidentally Deleted Partition Table On Lvm Physical Volume.
Jul 18, 2010I was trying to remove the physical volume from an old drive. So I opened gparted and told it to rewrite the partition table. The only problem is I targeted the wrong volume, I wiped the partition table on my 4tb raid5 array This 4tb array has everything! All my movies, tv shows, music. The only things I have backup up off site are my smaller files like documents. I was about to lose my whole media collection.
I did some research and found a solution that I will post here in the hopes that someone will google "I deleted the partition table on my lvm" and be find the solution.You should find in your filesystem a /etc/lvm/backup folder. LVM puts a copy of the crucial lvm information there every time you change the the volume group.
In this folder you will find a file for each volume group. In this file you will find the uuid for all of the physical volumes that make up that group.The first step is to recreate each physical volume with their original uuids. In my case I had only 1 physical volume, which was my raid5 array. My recreation command looked like this:
pvcreate --uuid cLrY02-zrVi-D0Vi-cIPB-6fF5-ed0c-XFF0os /dev/md0
Now I have a physical volume with the same uuid it had before. It is essential that you correctly match up the uuids with the correct physical deviecs.The recreated pv is empty, the volume group needs to be recovered. This is done by using a special tool and the backup file. For me the command looked like this:
vgcfgrestore --file /etc/lvm/backup/raid5 raid5
This tells it to recreate the volume group using the information in the backup file. The backup files looks for the uuid of the PV, which now matches the correct volume. The coordinates in the backup file match up to the data on the array an suddenly everything is back!
When I deleted my LVM partition table I did not damage any of the actual volumes on the volume group, I just wiped out the table of contents. The backup file had the information needed to rewrite this table of contents.
Debian 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) ?
Ubuntu :: Safely Removing Partition
Feb 11, 2011I have a 32-bit laptop running a dual boot with Windows 7 and Ubuntu 10.09 LTS.I've decided that Ubuntu just isn't for me, and I want to remove the partition and restore the extra hard drive space back to Windows 7.
Now, a few months ago, I accidentally deleted my Ubuntu partition through Windows Disk Management, and I ended up not being able to boot up my computer. I can't remember what the exact cause was, but I think it was a problem with the GRUB, and I think I fixed it by reinstalling Ubuntu. Does anyone know how I can safely remove the Ubuntu partition without having to go through all this again?
