Ubuntu :: Fdisk, Partitions, Hdds And Terms Of Storage?

Jan 18, 2011

i have a question regarding how data is placed on a media, for example the daily used hdd: when we talk about storage we often speak in heads sectors and cylinders. my question is if heads, sectors and cylinder is the true way data exists on a hdd platter?

lets take for example, disk_x
1000.2gb = 1000204886016 bytes
255 heads, 63 sectors/track 121601 cylinders.

fdisk -H 128 -S 32 /dev/disk_x each cylinder will be shrank to 2097152bytes, number of cylinders will grow to 476934. but everything will be much more aligned and readable or there is something i don't know and i will loose almost half of the total sector count on the hdd cause 63-32=31. i asked the partitioner just to use 32 sectors from each track and only 128 tracks of the cylinder.

or another example, if i have a cluster size of 4k. why not making each track use 56 sectors or 7 clusters. theoretically i have all files in my storage and each one of them occupies 14 clusters isn't it wiser to make it as described. what happens when i invoke fdisk -h -s params? what will be changed, the disc physically and the way it is accessed or only the partition table? you probably asking your self what the hell does this dude wants? i want to get maximum i/outputs and the widest bandwidth and the nicest readble partition tables and to understand better fdisk -H -S.

Ubuntu Installation :: Creating Partitions Using Fdisk?

Sep 30, 2010

I have a dell poweredge 2950 server which had red hat on it. I have installed ubuntu on top of it. I have replaced master boot record during the installation of ubuntu as I dont want use red hat anymore. During the installation it asked me for the space I wanted to give for Ubuntu and I provided 10GB. Now I can use only 10GB of my harddrive until I mount other partitions correct?

So when I type sudo fdisk -l I get the below printed:

Code:
Disk /dev/sda: 146.2 GB, 146163105792 bytes
255 heads, 63 sectors/track, 17769 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes

Ubuntu Installation :: Create Aligned Partitions With Fdisk On EBS?

Jul 17, 2010

After reading Markus Ewald blogpost on http:[url]...n-ssd-on-linux about Aligning an SSD on Linux I decided to give it a try.I have bought two 80 GB Intel X25-M SSD for my home server. The plan is to install Ubuntu 10.04 64-bit server and use the SSDs as system discs and vmware data storage using software raid for redundancy.After reading the blog post I am not sure how to make all my partitions aligned and set up on EBS (Erase Boundary Size)I am planning for four partitions:Boot, size 1GB

Root, size 25GB
Swap, size 4GB
Data storage for vmware server, size 40GB

According to Markus Ewald I should use 32 heads and 32 sectors.Using the live CD, I started using fdisk -S 32 -H 32 /dev/sda.Fdisk can create partitions using cylinders or sectors, and now I ran into trouble.

First partition /boot must start on cylinder 2 (or sector 1024). Size is 1 GB and the following partition should be aligned and start on a new EBS block. How do I do this with fdisk?Should the next partition start on a new cylinder? Otherwise, after formatting, fdisk gives a warning that the partition is not aligned to the cylinder size? The overall question is how to format four aligned partitions which all are aligned with Intels X25-M EBS. EBS for Intel X25-M is either 128KB or 512KB (Have not found a confirmed value yet)

Ubuntu :: Ext3 Partition : Fdisk Is Not Showing Any Partitions On The Drive?

Apr 24, 2010

I had a 500gb hard drive that I wanted to use on my Ubuntu system as a media storage drive. The drive originally had two partitions on it,one was a Dell Recovery partition and the other was a Windows Vista partition. Using the Palimpsest Drive Utility that comes with Ubuntu, I deleted both partitions,created a Ext3 partition using 100% of the space and copied my data to the drive. After I finally got fstab to load the drive, I found another problem. First of all, when Grub loads, two options it offers are:

Windows Vista (loader) on sdc1
Windows Vista (loader) on sdc3

Aside from that, 100% of the drive is not being used by the Ext3 partition.It is showing 434.6gb available on the drive. Fdisk is not showing any other partitions on this drive, so A) why are the Windows loader options showing up under Grub and B) why do I not have 500gb available?Here is a copy of the output fdisk -l:

Code:
Disk /dev/sda: 80.0 GB, 80000000000 bytes
255 heads, 63 sectors/track, 9726 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes[code]....

Ubuntu :: Partitions Are Effed Up - Fdisk -l: Code: Omitting Empty Partition (5)

May 7, 2010

I have a 120GB HDD with a 22GB partition for Ubuntu and the rest for Windows XP. Windows finally died on me so I attempted a fresh install on its partition. However, the install threw a ton of errors so I used a LiveCD to re-install Grub and I booted into Ubuntu. I open up the disk utility to re-format the Windows partition so I can re-try re-installing Windows, but immediately I notice that the partitions are not right. If you add up all the partitions, they are about, say, 18 million terabytes over my HDD's 120GB capacity. Ahhh! What do I do?

I don't think anything is terribly altered, since I can still boot into Ubuntu, but I am completely confused and slightly worried that I might kill any chances to save my HDD I can't post a screenshot due to my post count, so the image loses some of its efficacy in making it small enough for an attachment. Here is the output of fdisk -l: Code: omitting empty partition (5)

Red Hat / Fedora :: Grub - Recover Without Using A Bootable CD - Fdisk -l Is Not Listing The Partitions

Jan 26, 2010

I am preparing for RHCE. While doing the lab I renamed /etc/grub/grub.conf as grub1.conf. Now (obviously) system boots on grub> prompt. Can I recover without using a bootable CD? Another problem that I encountered was, while doing lab for fdisk, I used command umount -al. Now, fdisk -l is not listing the partitions but giving a message:- /proc/partitions does not exist. If I reboot the system this is restored.

Ubuntu Networking :: Share NTFS Storage Partitions On HDD Over Network With Windows 7?

Oct 20, 2010

I have a desktop with Ubuntu and I've set up Samba to share files with my Windows 7 laptop. I can access my home folder just fine except for my NTFS storage partitions on the desktop's HDD and my home folder's Downloads folder (which times out whenever I try and open it).

Is there an alternative way to share files between Linux and Windows 7?

General :: Partition Gparted Fdisk / When Reduced The Size Of Some Linux Partitions Using Gparted?

Sep 18, 2009

I have 3 Ubuntu installations & a PCLINUXOS, plus Windows XP installed on one hard disk. I still can boot to each one of them and can mount each one using Ubuntu.

The problem "may" have occurred when I reduced the size of some linux partitions using gparted. I still have plenty of space in each of those partitions.

When I started gparted all of the HD was unallocated. I did that from each ubuntu installation and the PCLINUX installation, plus LIVECDs. All indicated the space was unallocated.

When I did an fdisk -l from a Puppy Linux LiveCD I got a normal start and ends of each partition.

When I tried it from Ubuntu installation or live cd, I received the following types of responses:

Code:
ubuntu@ubuntu:~$ sudo fdisk -l /dev/sda5

Disk /dev/sda5: 28.5 GB, 28566397440 bytes
255 heads, 63 sectors/track, 3473 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x00000000
Device Boot Start End Blocks Id System
ubuntu@ubuntu:~$ sudo fdisk -u /dev/sda5

The number of cylinders for this disk is set to 3473.There is nothing wrong with that, but this is larger than 1024,and could in certain setups cause problems with:

1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs (e.g., DOS FDISK, OS/2 FDISK) Plus the Windows partition seems to go over its limits.

Since all of my OS installations are still working, I don't know how critical this is. From reading another post, I understand this might be able to be fixed by making some changes in fstab.

Ubuntu Servers :: Mainboard And Storage System - How Both Storage Devices Will Be Supported By Debian

I'm interested in buying a new hardware for my company. The old server (now 10 years old) should be replaced with a new one. Till now, I was looking on different hardware suppliers, boards and different other places. I found a Tyan board [URL]. The hardware spec is quite interesting and the board would fullfill our claims.

how both storage devices will be supported by Ubuntu or Debian??

OpenSUSE :: 11.4 Slow In Terms Of Speed / Performance

Jun 30, 2011

I'm new to openSUSE and my computer is quite slow although my computer isn't that bad. I opened up ksysguard and it appears that my CPU is the bottleneck. My CPU usage is usually 100%, then after a few seconds, it goes down to 20-60% and then it goes back up to 100% after another few seconds. It says I have 141 processes running (I don't know if that's normal or not).

My Specs are:
CPU: AMD Duron (tm) processor 1.8GHz
Graphics Card: NVIDIA GeForce 6200
Memory: 2GB RAM

Ubuntu :: Use Multiple Words / Terms (boolean AND) With Gnome Search Tool

May 27, 2010

I just want to search file names, not their content.

Using gnome-search-tool, if I search for "word1 word3" I can't find "word1 word2 word3.txt" but I do find it (and too many others) if I just search for "word1"

I would have thought a boolean AND search would just be automatic, but I guess not. I've already come across searchmonkey, but I'm not smart enough to figure out how to set it up to do this - i.e. I don't want to have to use regular expressions or be typing "*" all over the place.

P.S. I do use google desktop search, but I hate using it as the results are way too narrow to be of any use and haven't been able to figure out how to widen it.

P.P.S. I also found this: In terminal type gconf-editor and find gnome-search-tool in the Apps. Then look for the field quick_search_second_scan_excluded_paths and change the slash to nothing, i.e. delete the "/".

It worked for my ubuntu 10.04 pc, but not this one (ubuntu 9.1) - so I thought maybe there's another way...

Ubuntu Servers :: Noob Setup Simple SMTP Relay Contradiction In Terms?

Jun 7, 2011

Is the term a 'simple SMTP relay' a contradiction in terms?!I have an elderly Dell server on which I have just made a fresh install of 10.04 LTS server. I had 8.04 running on it for a long time, but I haven't tried an SMTP server before. It is a headless server with CLI (no GUI) and the latest version of Webmin installed.I have a basic LAMP server installed for a few websites using PHPbb and Joomla, and also I run a Mediatomb server for our household. When I installed I also chose to install mail services, but these remain masked behind NAT at the moment

I now want to set up an SMTP relay server so when I am working away and using different wifi points or my notoriously unreliable 3G dongle I can always send emails through the home server (from my iPhone and my laptop) rather than having to look up the SMTP server for each ISP of the place where I am working.

What I want is an authenticated server which takes my email and redirects it to my home ISP's SMTP server. I need only 3 authenticated users to have access (myself, my wife and my son). I don't need (or want) any incoming mail services at all.

Useful modules installed are: Dovecot, Postfix, Procmail mail filter, PAM - but how do I set them up?

Is there any simple setup that I could do, preferably through Webmin, but I can handle CLI if necessary?

I have looked at the Ubuntu help pages, but it looks so complicated to set up something that seems like it should be so simple to me.

General :: Cause Any Harm To Use Dual Operating Systems Like Windows In Terms Of Losing Data?

Aug 12, 2011

I have Windows 7 working on my laptop. I have 20GB space unpartitioned. I want to install a flavor of Linux like Fedora or Ubuntu in that space, but I have heard that keeping a dual OS configuration sometimes results in losing data stored on the hard disk. I've also heard that it may sometimes cause unrecoverable problem because when Linux is loaded on hard disk it will take over the boot loader from Windows.

Is this correct? Moreover, I have 6 partitions in Windows, but if I use a Live CD for Ubuntu or Fedora to boot, then it is not showing some partitions -- sometimes it shows only 4 or 5 partitions. What might be the problem, and how to resolve it without formatting the whole hard disk and repartitioning it?

Ubuntu :: HDDs Keep Swapping The Location?

Jan 1, 2011

I have two HDs, one is a 80gb OS drive(Parallel ATA) and the other is a 1T storage drive (SATA). Well after each reboot they swap between /dev/sda and /dev/sdb, over and over again. One boot the OS is /dev/sda and the next its /dev/sdb, same goes for the second drive. This makes it difficult to setup fstab so it will mount the large storage drive on boot.

Ubuntu Installation :: HDDs Aren't Being Detected

Oct 4, 2010

My reality distortion field went through a polarity shift today, and nothing's been working like it should. After the 10,000th problem, I decided to just make room for a fresh lucid install and the accompanying stability. It worked well, then I had some sort of a boot error upon reboot. So then I just decided to reinstall. The problem is that neither of my 2 internal HDDs is registering. Currently sda is an 80GB drive with a slackware install, sdb is a 120GB with a 60GB mint partition and (upon previous install) 60GB lucid partition. I've got no important data on any of my partitions yet, but also no net connection. I have install dvds for lucid, mint kde 9, and slackware plus a gparted live. I'm seriously considering making this machine a slack standalone, but then I've got legacy nvidia drivers to deal with.
