Ubuntu Installation :: Swap Partition Locked?

Aug 3, 2010

I have Ubuntu 10.04 installed. When I run Ubuntu 10.04 LiveCD and I start GParted I see that there is a "key" on my swap partition marking it as locked I guess. When I right click, I cannot select "Delete" option. What does this mean? What if I want to rearange my partitions sizes including swap partition for whatever reason?

Debian Installation :: Wiped Windows Partition With Swap And LVM Partition

Jan 17, 2015

I 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, 2009

I 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 Installation :: Failed Upgrade: Partition Locked As Read-only?

Nov 26, 2010

I was updating from 10.04 to 10.10 earlier today when my laptop shutoff in the middle. I fixed a grub error by reinstalling it with a live-cd, and found out I had a "kernel panic-not syncing: VFS: unable to mount root fs on" waiting for me. I booted an alternative kernel and tried fixing things from there, but got "general error mounting filesystem". So, I tried a live-cd and when I mount the partition, it is read-only. I tried running fcsk to no availThe only thing I could find helpful was this."It's probably because your filesystem has suffered a failure - it is configured by default (in /etc/fstab) to remount as read-only in such cases in order to minimise the risk of data loss."

Ubuntu Installation :: 10.04 - Create Dual Boot And Partition Locked

Jan 23, 2011

I had Ubuntu 10.04 on this machine and wanted to convert it to a dual boot. It's a 500GB hard drive. The HDD had 3 partitions: one really big one, and two swap areas of about 6 GB each. I ran GParter and carved the big partition into a 100GB partition and a 400GB partition (less the swap areas). Then I installed Windows XP into the 100GB partition, then installed Ubuntu 10.04, selecting the "create dual boot" option.

It dual boots beautifully, and everything runs just fine. But I find that Ubuntu has split the 400 GB partition into two 200 GB partitions, and one of them is simply off-limits. I can see it, but I can't write to it. The attached png shows the Disk Utility, with the mystery partition selected. Its only contents is a folder called lost+found; I cannot open it.

Ubuntu Installation :: Locked Out Of Windows Partition With Grub - Error: No Such Device: 2e3857fb3857c08f

Apr 5, 2011

I have two partitions on my HDD. A Windows XP (hd0,2) and an Ubuntu 9.10 (hd0,1).I have been using the Windows mainly and ran a program that changes the HDD's serial number. Now when I boot up and Grub loads, I try to access the Windows partition and get the following error:

Error: No Such Device: 2e3857fb3857c08f

I am still able to boot the Ubuntu partition but can not seem to get grub to point to the Windows partition any more. This is very frustrating as I really need to get back into that partition soon.

Ubuntu Installation :: Using FAT32 Partition As Swap?

Apr 5, 2010

I'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.

Ubuntu Installation :: Add Swap Partition Without Reinstallation

Apr 9, 2011

I'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, 2011

I 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?"

General :: Creation Of Swap Partition During Ubuntu 9.10 Installation

Mar 26, 2010

When 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.

Debian Installation :: How To Find Out If Swap Partition Is Active

Feb 12, 2015

I 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
root@DELL-DEBIAN:/home/hugh#
Code: Select allroot@DELL-DEBIAN:/home/hugh# cat /etc/fstab
# /etc/fstab: static file system information.

[code]...

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.

Debian Installation :: SSD - Garbage Collector And Swap Partition / File

Feb 27, 2015

After 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) ?

Installation :: Dual Booting Arch And Vista With Recovery Partition And Swap

Feb 13, 2010

The problem is, on a machine, you can only have 4 primary partitions. sda1 and sda2 are my Vista and Recovery partitions respectively, which eliminates two of my primary partitions already. I myself have never used logical partitions, and was wondering if any of the partitions the Beginner's Guide recommends (/, swap, /var, and /home) could be made logical, and if I even need a swap partition.

Ubuntu Installation :: Dual Boot With Windows XP On A 1TB RAID-0 Setup - Create A SWAP Partition

Mar 20, 2011

(This is for a 100% Clean install)

Q1) I was wondering if it is possible to Dual boot Ubuntu with Windows XP on a 1TB RAID-0 setup ?

Q2) Also, is it possible to create a SWAP partition (for Ubuntu) on a NON RAID-0 HDD ?

Q3) Lastly... I read GRUB2 is the default boot manager... should I use that, or GRUB / Lio ?

I have a total of 3 HDDs on this system:
-- 2x 500GB WDD HDDs (non-advanced format) ... RAID-0 setup
-- 1x 320GB WDD HDD (non RAID setup)
(The non RAID HDD is intended to be a SWAP drive for both XP and Ubuntu = 2 partitions)

I plan on making multiple partitions... and reserve partition space for Ubuntu (of course).

I have the latest version of the LiveCD created already.

Q4) Do I need the Alternate CD for this setup?

I plan on installing XP before Ubuntu.

This is my 1st time dual booting XP with Ubuntu.

I'm using these as my resources:
- [url]
- [url]

Q5) Anything else I should be aware of (possible issues during install)?

Q6) Lastly... is there anything like the AHCI (advanced host controller interface) like in Windows for Ubuntu?

(Since I need a special floppy during Windows Install...) I want to be able to use the Advanced Queuing capabilities of my SATA drives in Ubuntu.

Ubuntu :: Delete Snow Leopard Partition - Format Swap Disk Partition To Something Else

Feb 23, 2011

I 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, 2010

I 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 :: Swap Partition Access / Cant See That Partition

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.

Ubuntu Installation :: Grow Boot Sector. Delete Swap Partition. Can't Boot Afterwards.

Mar 7, 2010

I'm running 9.10 off of a 4 GiB CF card. I keep running into space issues with updates, so I purchased an 8 GiB replacement card. I've cloned the 4 GiB card to a .IMG file using DD.I've then copied the 4 GiB image back to the 8 GiB card using the Ubuntu startup disk creator program. Once done, I'm able to properly boot off of the new 8 GiB clone.Unfortunately, the clone ends up with 3.67 GiB of unallocated space at the end *see attached). I tried deleting the "extended" partition that the swap is located at after booting from a Live CD and the system was unable to boot after this. I was thinking that I would delete the swap entirely and create a swap file after I merged the existing partitions, but I was unable to do this.

best way to do this (e.g. get one large 8 GiB partition with my old image on it)? I still have the original untouched 4 GiB card and also have an external CF drive if I need to redo the cloning. I've also used Clonezilla before, so perhaps there's a way to do this that allow me to grow the image as it's being cloned.
