my friend was installing ubuntu when he while editing the table from the installation menu, chose to shrink the partition and use it as swap, he didn't realize he was using the actual partition not the 1 to be created as swap.so he ended up with 160 GB swap and 15 GB NTFS partitions.will deleting the partitions and recreating the NTFS partition again restore his data?
View 2 RepliesI have a kickstart script that attempts to create user "joeblow" with an encrypted password. The user is created okay, but the password does not seem to "take". After installation is complete, and the system is rebooted, this is the relevant portion of /etc/passwd:
Code:
This is the relevant portion of /etc/shadow:
Code:
Where there are two exclamation points, I would expect the encrypted password (as is the case for the root user, which is also created in the kickstart file).
The relevant line in my kickstart file looks like this:
Code:
That password string, which is 34 characters, is the word "password", encrypted with this command:
Code:
Also in my kickstart file is this line:

After the install is complete, I reboot and attempt to log in as "joeblow", but no dice. If I log in as root, and manually put the above encrypted password into /etc/shadow for jowblow, I can then log in as joeblow.
I'm resizing an ext4 partition from 100gb to 40gb (I only used 20gb of it or so). Lets say partition is at /dev/sda1. I used
Code:
efsck -f /dev/sda1
to check it
Then I did
Code:
resize2fs -p /dev/sda1 40G
to resize it
When I check fdisk -l, the partition is still 100gb. I have a feeling I resized ONLY the filesystem to 40, but the partition is still 100gb. How do I finish this?
I am trying to install Ubuntu through the live CD to a resized partition on a External HDD.But when I try to boot into it, I get:error: unknown filesystem grub rescue> The boot loader is on the external HDD
View 3 Replies View RelatedI installed openSUSE 11.2 RC1 yesterday. (It was a fresh install.)I installed to a 5 GB logical partition at (hd0,10) which is /dev/sda10. (BTW, that's grub2 numbering). There is a 300 MB boot partition at /dev/sda1 or (hd0,1).After I got everything set up in openSUSE exactly the way I wanted it, I realized 5GB is way too small for openSUSE KDE, even though ALL data is on another partition.Next step: booted to a live CD (with grub2) and used gparted to remove /dev/sda11 (another 5GB logical partiition), then resized the openSUSE partition (/dev/sda10) to 10GB in gparted.
View 14 Replies View RelatedI 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:

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 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?
I have already done the installation process following the guide on Ubuntu's site, got everything up and running but the partition that I made in the installer was too small. I was then directed by a friend (a slightly less inexperienced newbie) to modify this through Easeus Partition Manager. I shrunk the Windows 7 partition to only the space that was in use, giving the newly unallocated space to the Ubuntu partition. Set the changes and rebooted the computer, then got the message "unknown filesystem, grub rescue". Now have no idea what to do with this. What happened??
I've been scouring the forums for something helpful but I can't find anything that is a comparable circumstance.I can still access Ubuntu through my flashdrive.
I just finished installing Karmic Koala on my computer a little while ago... and I chose to partition the drive manually. My computer has 2 hard drives:
Here's the HDD which boots first and has Grub and Ubuntu on it:

And my second HDD which has Windows and a backup partition called "datas":

And here's a copy of my /etc/fstab file:
Code:
# /etc/fstab: static file system information.
#
# Use 'blkid -o value -s UUID' to print the universally unique identifier
# for a device; this may be used with UUID= as a more robust way to name
# devices that works even if disks are added and removed. See fstab(5).
[code]....
The ext3 partition on the 250GB drive called "datas" is an old partition that I created while I was still using Intrepid... and it works just fine. However the partition called "archives", which I created during the installation of Karmic, doesn't seem to work properly. For some reason I can't write any files or folders on it. Why is that?

View 4 Replies View RelatedI'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 9 Replies View RelatedI 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?
View 1 Replies View RelatedI'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.
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?"
Is there a way to encrypt your swap partition after installation?

View 7 Replies View RelatedWhen 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.
I have 1GB ram and 2GB swap space. It seems that linux programs somehow are aware that there are 3GB ram avaialable and pretty fast uses more than 2.5GB. System becomes unresponsive because of excessive swapping. On the other hand if I disable swap, using the same programs (chrome, vlc, openoffice) I get only ~600MB use while watching videos and browsing net.
I know, that linux uses all available ram to enhance performance, but in my case, it really hurts the performance. I also cannot leave the swap off, because I sometimes want to do some 3d editing, and then the memory usage can exeed 1GB.
So basicly my question is, if it is possible to force swap usage only when really needed, and make it so, that swap is not considered free ram and filled up with useless junk. (For example, if swap is enabled VLC player just loads whole movie into swap! - which of course is useless, because movie is located on the same hard drive, but VLC is not the only offender)
I have booted from the .iso cd I made on my Mac last night and was tempted to install it on a 6gb partition that I have on my main HDD but was a bit scared to go past the fourth (or so) step in manual installing where I pick that partition and *do what?* Is it going to install the OS on that partition and leave everything else alone to give me a dual booting PowerMac? It doesn't quite say. I am fearful of screwing up my little ol' machine. Can anyone direct me to something that gives a step by step in manual installation on an already created (HFC+) partition to create a dual booting PowerMac?

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?

View 2 Replies View RelatedAfter 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) ?
