Slackware :: Swap Partition Not Working - Shown Empty
Feb 5, 2011
The swap partition says that it is empty. When I installed Slackware I'm sure that I pointed to the right place for the swap. Or does it not show any size because none of it is being used?

Currently running Slackware64 13.1 on a notebook and for the most part everything works fine. Only problem I am running into is with hibernation, where sometimes it will go into hibernation without a hitch and sometimes it will stall after blanking the screen and never turning off. For the most part pm-suspend.log looks fine every time, whether it goes into hibernation or not. My current system has 12GB of RAM and my swap partition is roughly 12GB. For the most part my RAM usage right before going into hibernation is always under 1.5GB with maybe 600MB floating in the swap partition. Could the size of my swap partition be too small even if RAM usage is nowhere near max?

When I load the disk I can view my backup drive properly but when I try to view my working drive it shows it as being empty. I also noticed that I had a 1 mg unallocated partition at the beginning followed by my ubuntu partition.
I then ran gparted in terminal and it did show the partition as having my system on it but I am not able to perform any tasks. No moving or resizing.

The swap partition is not working on my computer, I just upgraded from 9.10 to 10.04. I don't remember whether it was working or not in 9.10. Here is the output from TOP:
top - 23:40:29 up 2 min, 2 users, load average: 2.69, 1.37, 0.52
Tasks: 150 total, 1 running, 149 sleeping, 0 stopped, 0 zombie
Cpu(s): 5.0%us, 2.0%sy, 0.0%ni, 0.0%id, 93.1%wa, 0.0%hi, 0.0%si, 0.0%st
Mem: 315168k total, 302344k used, 12824k free, 35264k buffers
Swap: 0k total, 0k used, 0k free, 127912k cached
I am new to Ubuntu so I am not quite familiar with UNIX commands yet. I would like to know how to find the ID of my swap partition (I am positive the there is one) and what lines to add or change in my FSTAB to activate the swap partition.

In our cluster, both the server and worker had been gone to swap and the performance is extremely slow. Although currently the memory is free but I don't know why the in the swap area is still being there and ubuntu doesn't move them to the memory and empty the swap.
On the other hand, when I run
Code:
sudo swapoff -a
on the server it says:
Code:
mahmood@server:~$ sudo swapoff -a

How would I combine a empty partition with my existing partition? A reinstall is just an option and I need more disk space

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.

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?

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.

I wonder whether to place swap partition on LVM or on standard fdisk partition which will not be in LVM.What is better and more often used on production ?

I'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. Not really understanding what this meant I chose another partition on my drive with some free space but also a lot of my data. Needless to say I now 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.

I have googled and looked around on the forums but I couldn't find anything that directly answers my question. I have a dual boot set up with Vista and Ubuntu 9.10. My hard drive is partitioned into dev/sda1 (where Vista resides) and dev/sda2 (where Ubuntu resides) and /dev/sda4 which I use as a shared hard drive for the two operating systems.
When I first installed Ubuntu on dev/sda2 I used gparted to make /dev/sda2 a 10 GB partition becuase I wanted to try putting ubuntu on a very small partition. Since then I used gparted to expand /dev/sda2 to 32GB. But when I use System Monitor (System--->Adminstrative----->System Monitor) it shows only that the /dev/sda2 space is 10GB (and says that there are only 2.9 GB) remaining unused. Yet when I use gparted to look at the partitions, it says that /dev/sda22 is 32 GB with 3.9 GB remaining unused.
I am wondering if anyone knows why they show two different sizes and what I can do to fix the size being shown. When I tried to make a tar gz back up of my system iit returned a message warning me that my /dev/sda2 partition was almost full because it put the 1.5 GB tar gz file in my home drive (which I suppose the system monitor only sees as a 10 GB space that already has 7 GB in it).

I have a logical partition formatted with NTFS and created (from Windows) after Ubuntu 9.10 was installed. It's name is "Volume". Now, it doesn't show under places nor nautilus. I think it is shown when using the Live CD again. It is shown in Volume Manager. How can I have it show up next to my other partitions?

I've always been a fan of Fedora since the first distro. I remember downloading 4 cds and then relizing that I only needed one. ;D Anyways, I've been using Ubuntu for years. I've gotten tired of the Ubuntu fan boys and just the responses I get from saying that Ubuntu was my distro. I've moved to Fedora to simply learn and understand the yum system which I already enjoy using in the terminal.
All of that set aside, I've kept my Ubuntu /home partition (ext4) in tact as I always do moving from distro to distro and have never had a problem. The thing is, all the distros I've tried have deb based. Now, my /home partition is roughly 56gbs. Nautilus shows free space as 8gbs currently on my parition so I know the files are still there but why won't Fedora read them? It must be a permission thing, but what? If I must loose my /home it's fine, however I'd much prefer not to.

I have Ubuntu in one partition . The partition is about to be full..I have a spare partition which I thought could merge with the existing..But I guess it is not possible. I am slightly confused with the way linux stores the files. There is a root directory and within that there are boot ,Var,tmp and home..
Suppose I install an application from a package manager , I really do not understand where the path is ...Supose I want to store certain new applications in the spare partition , how do I tell the system? Also while installing it doesnt give a choice regarding the path ...All I see is a couple of files exracted and when it completes , it sits on the menu neatly. From a storage perspective how do you gain control? Say in Win , normally any package will ask for the path which you can customize..How do you plan the storage of files in Linux?

So the other day I got myself a nifty ThinkPad x100e. I immediately removed windows 7 started, and installed UNR 10.04.It has a 250GB hard drive, which I decided to partition, so that I can keep all my stuff on the new partition, and then a fresh format or install of the OS would be easier.After struggling to take ownership of my own damn partition after creating it and mounting it, I discovered a rather interesting problem. I KNOW the partition is empty, but when I right click and go to properties, it says that 10GB is already used? This is rather confusing to me

I've been using Slackware for awhile now on my laptop without a single issue (well except that I can't get the screen brightness to change, but that's a separate issue).
I logged in today and went to the terminal and when I type the letter 'e' it is not shown or recognized. It works when I 'su -' and enter my root password which contains the letter 'e' twice, but otherwise is not recognized.
I have no idea where to even start with this problem. I've logged out and back in. I've restarted twice now, but the problem is not going away. Obviously, my keyboard is working properly as I am typing this message with the letter 'e', but in the Terminal it is not recognized.

I just reinstalled Ubuntu Lucid Lynx and an old problem has come back. For some reason I couldn't fix it even in my previous installation. The problem is the top gnome panel. See the photo below: As you can see, the network icon is not shown properly while the Me menu is being shown twice. I can't even restart or log out or shut down at this situation without pressing the keystroke to turn the power off.

1) At Sys Ananysis I get; The partitioning on disk /dev/sda is not readable by partitioning tool parted... You can use the partitions on disk /dev/sda/ as they are. You can format and asign mount points on them. But you can not add, edit, resize, or removefrom that disk with this tool. I click OK

I gave upon 11.3 M4.Tried installation by text mode but there's another screen showing various USB devices status superimposing on the Linux text install. Returned to Live installation via Live CD. Installation completed > restart >autoconfig failed. Tried live installation again but Suse kept suggesting installing into one of the empty 2 Gb partitions. Also had problems with Gparted Live 0.5.1-1 CD because somehow the keys froze. Had to replace it with 0.5.2-1. I am installing 11.2 on a laptop but right now I am stuck with frozen "Creating cache files for fontconfig". This has taken over an hour and nothing seems to be happening. I have successfully installed openSUSE 11.2 on an older laptop and a desktop. Also experienced installing Windows 7, Ubuntu and PC-BSD on both types of machines.

The partition is formatted to ext3, starting with block 1 on the drive. The mount point for /dev/sdc1 lists 0 files when doing `ls -A` `df -h` shows that the partition has 92MB used. How is this space being used, and how can I free it up?edit: I guess this isn't a newbie question.

I have a server running Fedora 6, which I wish to upgrade to Centos 5.4. This will be a lengthy switch over because of all of the apps I need to convert etc. As a precaution, I would like to keep my old Fedora running as multiboot. I have a boot partition, a fedora partition (root), and an empty partition for Centos.
Can I run the Centos installer and direct it to install onto the empty partition (I don't care if it formats it)BUT only add to the boot partition (not reformat it).? I don't want to lose the kernels/images on the boot partition, and from what I've seen most installers wipe out the boot partition prior to adding their own files.

I recently used BootCamp on my MacBook (2.1) to partition my hdd and install Ubuntu (karmic), and I am having trouble with the wireless connection. On the mac partition it works fine, but on Ubuntu there are no wireless networks shown in the network-dialog. Previously I had only a Linux-partition on the same machine, and this was not a problem. Also the trackpad does not work at all. Does anyone know what to do about the network connection? Also I should mention that I first installed the AMD64-version of Ubuntu, which worked fine even though my macbook uses intel. Im tempted to just go back to the amd-version, any views on that?

I have a broken DVD drive and no others available right now to burn a DVD iso to so I'd like to use a empty hard disk instead.
I've tried Unetbootin but that only copies a few megabytes of files - the rest of the image data in the ISO is ignored.
I have verified the ISO is valid and working with VirtualBox. It's MD5 hash is also as expected. But I need to boot at the real bios not an emulated one.
I've also tried things like:
sudo cat /disk/image.iso > /dev/sdb1
and that got "Permission denied" -

Just ran into a problem involving mdadm, a disk which had been in a raid array, and an attempt to reformat. Basically, I went to reformat some partitions which had been in raid, and one of them threw the error andy@andy-desktop:~$ sudo mkfs.ext3 /dev/sdb5 mke2fs 1.41.11 (14-Mar-2010) /dev/sdb5 is apparently in use by the system; will not make a filesystem here! An attempt to umount revealed it was not mounted. lvdisplay and fuser did not reveal anything to me, so I just started looking around. I was graphically navigating /dev and noticed a /dev/md_d0 which did not look like /dev/md_d1 etc (it was missing a little arrow). I had not seen this notation before (my raid was md0), but figured it couldn't hurt to try stopping it.
andy@andy-desktop:~$ sudo mdadm --detail /dev/md_d0
mdadm: md device /dev/md_d0 does not appear to be active.
andy@andy-desktop:~$ sudo mdadm --stop /dev/md_d0
mdadm: stopped /dev/md_d0
After this, the partition formatted fine! I saw a lot of instructions including zeroing the partition and removing a logical volume, but the above was the only thing which worked for me! Just posted it in case it helps someone else. I know I've not been terribly technical!

Currently I have ubuntu 10.04 LTS as the only OS.I have two partitions one for ubuntu and it is ext by default for ubuntu's files.The other is empty NTFS. (yes, it is formatted in NTFS but I haven't saved anything yet on it).The problem is: I want to install win xp sp3 on this empty ntfs partition safely (without losing ubuntu).My friend told me ubuntu will be lost even if I didn't touch its own partition.
