Ubuntu :: Installation And Partitions - Recovery Disks?

Apr 3, 2011

Brand new HP Compaq Presario CQ56, want to dual-boot 7 & Ubuntu. Too many partitions I think:

HD0 - 298.09 GB
279.36 GB NTFS
18.43 GB NTFS
103 MB FAT32

Want to add Ubuntu + Swap in the 90 or so GB range, fairly new to partitioning. Trying to create recovery disks using system tools is over 16 Gb, for that kind of expense I may as well just order recovery disks OEM if (When) Windows falls apart.

Fedora Installation :: Error: Could Not Allocate Requested Partitions - Not Enough Free Space On Disks

Jul 11, 2010

I'm trying to install Fedora 13 on my HP dv6 laptop and when I try to use the Use Free Space installation type, I receive a Partitioning Error: Could not allocate requested partitions - not enough free space on disks. Before I started the install, I used the Disk Management utility in Windows 7 to shrink the volume of the C: drive down to 242 GB and leaving 210 GB Unallocated. Here is what the screen looks like when I select Create Custom Layout (also receive the not enough free space error):

Device (sda) Size Type
sda1 199 ntfs
sda2 248,018 ntfs
Free 215,175
sda3 13,443 ntfs

Ubuntu Installation :: XP With Existing Setup (Partitions) - Error "Setup Did Not Find Any Hard Disks Installed On Your Computer"

Feb 18, 2010

I'm using Ubuntu 9.10 and previously had a separate partition with another distro on it. I decided to delete the other distro's home and swap partitions and install XP in place of it. I've been following these instructions: [URL] and [URL] I have gotten to the point where I am booting to the XP CD and want to install it, but I get the message, "Setup did not find any hard disks installed on your computer" when I should be getting to the screen that asks me to select a partition to install XP on. This is what my HDD looks like in GParted:

I want to install XP in the unallocated partition, but I have a feeling I screwed up somewhere along the way and probably don't fully understand the whole thing. Even if I try to format the unallocated partition to NTFS I can't make it a primary partition (I assume because it's within sda2). The very last thing I want to do is delete my Ubuntu partition and start from scratch, but if that's my last option let me know.

Ubuntu :: Where To Store System, Home And Swap Partitions On Two Disks

Dec 22, 2010

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:


disk 1: [beginning] ubuntu | home | others [end]
disk 2: [beginning] swap | others [end]

My situation now is, according to guides I read before:


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?

Ubuntu :: Repair MBR Without Mess Up The Windows And Recovery Partitions

May 11, 2011

This post is a follow up to this one: [URL] My computer is an IBM R52 running Windows Professional (previously dual-booting with Ubuntu 10.10, but that's gone now, and I don't dare reinstall it until the HDD partitions and mbr are properly working again). I think that the shred command mentioned there simply messed up my MBR, and maybe my partition table. Here's the partitions on my HDD:

Disk /dev/sda: 60.0 GB, 60011642880 bytes
255 heads, 63 sectors/track, 7296 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x7e93bd30

My question is, is it safe to use something like SuperGrub to repair the MBR? I really don't want to mess up the Windows and recovery partitions. I've done plenty of research on this, but am not confident until someone says that it works in my case.

Ubuntu Installation :: Which Disks Can Be Main Boot Disks

Mar 31, 2010

I have/had a PC with several hard drives, and a mix of ubuntu and windows on multi boot.The old boot drive died screaming, and I need to start again. (But my data is safe! yay!)

Is there anything special about which drive can be the main drive to start booting from? Or to put it another way, can I install to any of the other 3 and expect it to work, or do I need to switch them around so a different drive is on the connections for the recently dead one?

Fedora Security :: Selinux With Homedirs Spread Across Multiple Physical Disks/partitions?

Jun 10, 2010

By fiat I must distribute my homedirs across multiple physical disks/partitions. Unfortunately this is not open to discussion so obvious solutions like a lvm home partition are not available to me. The issue: Users created with homedirs on the main home partition (the one created as home during the f13 install) behave as expected, but if I create them on a different partition (home9 for the sake of this example) the users are not able to login (dropped back to login screen), nor run x-apps if su -'d to in a konsole.

If I 'su - <user-on-home9>' in a konsole, I get delivered to the /home9/<user-on-home9> as expected, but x-apps fail with the error: 'cannot open display: :0'. This can be temporarily fixed with the command 'xhost +SI:localhost:<user-on-home9>', but I would rather fix it permanently at the source.

This appears to be an selinux problem from the following.The contexts of the the two rootdirs are the same

% ls -Zd /home /home9
drwxr-xr-x. root root system_u:object_r:home_root_t:s0 /home
drwxr-xr-x. root root system_u:object_r:home_root_t:s0 /home9
but when I create the users (using useradd or the gui) their respective contexts differ:
% ls -Zd /home/user5 /home9/user6


So, my questions for you selinux experts are 1) is it possible to have homedirs spread across multiple partitions with selinux, and if so, how, 2) Why, even when I manually set the dir/file contexts to match a properly functioning user5 from /home, do users from /home9 still not work (as far as login and x-apps).

Hardware :: Aligning Partitions On "advanced Format" WD Hard Disks?

Jul 27, 2010

the recent versions of fdisk on Fedora 13 and Ubuntu 10.04 are supposed automatically to solve these things around 4k sector aligment thing if one starts fdisk with -u and -c flags. But I'm getting confused as the heads / sectors informations always differ every time I create a partition.I have WD Green 1.5TB disk. I want 2 partitions. sdb1 with 1.3TB and sdb2 with the remaining space. Here's how it looks like. When I create the first partition (1.3TB one), I get following listin with fdisk:


# fdisk -lu /dev/sdb
Disk /dev/sdb: 1500.3 GB, 1500301910016 bytes
78 heads, 37 sectors/track, 1015342 cylinders, total 2930277168 sectors
Units = sectors of 1 * 512 = 512 bytes

Ubuntu Installation :: Installer Won't Recognize Partitions - Error Message Saying Partitions Over Sized

Mar 22, 2011

I used Ubuntu before, without problems but since the 10.04 version it won't recognize my partitions. I formated my laptop and partitioned it, installed Windows 7 64bit, which I need for my work, and wanted now to install Ubuntu 10.04/10. I then used GParted to check my Harddisk and it is having troubles to recognize my partitions, too while Windows finds them. GParted is giving me an error message saying my partitions are oversized. I am still in the beginning of my Linux experiences and so I don't know what to do. I have two 250GB harddisks (how Windows recognizes them),

Ubuntu Installation :: CD Doesn't Detect Partitions But No Apparent Overlapping Partitions?

Mar 3, 2010

Xubuntu 9.04 installation CD not detecting any of the current partitions. This all started when I reinstalled windows XP a few days ago.After, the computer wouldn't boot into GRUB and would boot directly into windows.Other threads have dealt with a similar issue, that of overlapping partitions causing libparted/parted/gparted to detect the whole drive as unallocated space. The problem in these threads seemed to be a corrupted partition table, in which the partitions overlapped with each other. So of course I checked the output of fdisk -l for overlapping partitions, but I don't see any obvious overlapping partitions. I've noticed that the partition that used to be linux swap isn't showing up in the partition table at all. I might just be missing something simple here and would like another set of eyes to help me figure this one out. Does the problem have anything to do with the partition table being out of order (ie. not in order of what regions they cover on the drive)? From the liveCD I've run


sudo fdisk -lu
sudo sfdisk -d
sudo parted /dev/sda print

and have received the following output:


ubuntu@ubuntu:/mnt$ sudo fdisk -lu
omitting empty partition (5)
Disk /dev/sda: 60.0 GB, 60011642880 bytes

Ubuntu Installation :: Order Of Partitions For Root / Home And Swap With Respect To Windows Partitions?

Feb 9, 2011

I 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?

Ubuntu :: Lost "Regular" In Grub, Only Left With "Recovery Mode" And Other Partitions?

Apr 30, 2011

I updated to 11.04 recently, no problem. Chose to merge the old and new Grub files together. Rebooted to finalize everything, and my Grub menu had lots of doubling up of options, the old kernel, as well as two options of Windows XP (the old option that I'd put on Grub, and what I suspect was 11.04's recognition of another partition, as it was titled "Windows XP ... (on dev/sda2)")Then I fired up Grub Customizer, re-read and double checked everything, and removed all the doubling instances. All good. Shut down for the evening.

Booted up the PC this afternoon and my Grub menu looks thus (adjusted with artistic license, just so you get the picture):Windows XPUbuntu 11.04 (recovery mode)MemtestMemtestDell Utility PartitionWindows XP (on dev/sda2)I've lost the option to choose regular Ubuntu.I've gone into recovery mode, tried the "Update Grub" option, rebooted, but nothing changes.Now, there's a terminal login on Recovery Mode. I am effectively an Absolute Beginner when it comes to the terminal - I know a couple of commands, am eager to learn more when I have the time, but really couldn't tell you what the hell I'm doing. The last thing I want to do is make this worse by fumbling through code. This isn't Zork.If anybody would be kind enough to provide the terminal commands to change the Grub menu to add regular partitions, I'd be very grateful. If there's a different fix, equally good. If anybody's got any comments, diagnoses, verbal abuse, heap it on. I'm here to learn.

Ubuntu :: Recovery Menu (in Recovery Mode) Does Not Work?

Aug 18, 2010

I've got a, as it seems to me, strange problem.I've inadvertently deleted my user from the group admin so I'm in the same situation of a lot of other users (read a lot of messages about it).My problem is that when restarted in recovery mode there is no way I can choose the 'drop to the root shell' or similar in the menu.The menu appears for a second and then I've got an empty screen. If I press a key I've been requested for a username and password that of course is not what I need.

Debian Hardware :: Servers Which Contain SATA Disks And SAS Disks?

Feb 25, 2010

I have servers which contain SATA disks and SAS disks. I was testing the speed of writing on these servers and I recognized that SAS 10.000 disks much more slowly than the SATA 7200. What do you think about this slowness? What are the reasons of this slowness?

I am giving the below rates (values) which I took from my test (from my comparisons between SAS 10.000 and SATA 7200);

dd if=/dev/zero of=bigfile.txt bs=1024 count=1000000 when this comment was run in SAS disk server, I took this output(10.000 rpm)

I did a fresh install of 11.04. It didn't let me choose custom mount points for my disks, so I left non-system partitions unmounted in the installer. Big mistake. It seemingly screwed with two of my disks. I can see them in disk utility, but disk utility cannot identify partition information.

Ubuntu Installation :: Format Both Disks Before Reinstall?

Nov 19, 2010

Reformatting two drives before re-installation. I'm new to Linux generally. Can someone give me instructions on formatting the hard drives? I have installed ubuntu on a machine that had been running Windows for a while. Since Windows worked the boot drive for years, I decided to switch the positions of the two drives; putting the old data drive into the boot position.

Apparently, ubunta was too smart for me. I guess it discovered the Windows installation, and decided that's where it should be installed too. Now, what I would like to do - and I would really like to do it this way - is reformat both the disks, wiping out everything that's on both of them; before running another installation.

BTW: the old data drive is still NTFS, and I don't want installations own both disks - reformatting and starting fresh seems nice and clean, if not entirely necessary.
