I installed CentOS on a IBM server. The server has 4 HDD of 537 GB each. On one HDD, OS is installed and i am creating a partition of 500GB on other HDD. The partition is created but whenever i am going to format it by using: mke2fs -j /dev/sdd or mounting it by using:mount -a Then, it returns an error "/dev/sdd is already mounted or busy".

I am using NFS to mount large LUNs from my SAN.I have one already setup and configured. I am adding an additional partition from the same SAN but I am confused on the setup. I know the LUN is connecting to my NFS server correctly because I see it listed in my /proc/scsi/scsi as an additional LUN. What I don't see is the drive being displayed in fdisk -l. I did notice one thing though, when I disable the host mapping from the SAN, my disk information changes from /dev/sdb TO /dev/sdc (see changes below)
Without host mapping to SAN:
Disk /dev/sda: 13999.0 GB, 13999026470912 bytes
255 heads, 63 sectors/track, 1701951 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

How long does hardware Raid card (raid 1, 2 drives)take to mirror a 1 TB drive (500gb used)?Is there a general rule of thumb for this?4 hours? 12 hours? 24 hours?
View 1 Replies View RelatedI 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?
Currently my system runs on two disks, sda 30GB and sdc 1GB. sdb is my data disk. I have set the partitions as sda1 /boot, sda2 /(root) and sdc1 /(swap).
Thinking that sdc was udma33 i used the disk for a swap area. Later i found out that it is pio4 and i want to relocate my swap area to sda.
Using GParted Live i am planning to create a swap partition to sda. Will fixing the entry in fstab be enough to correct this or do i need to do something more?
I could also use some advice on which live debian image i can install in sdc, to use for rescuing purposes. The capacity of the disk is 1080MB.
As a side note, the images i find for usd-hdd are direct download. Are there any torrent files for these?
I'm trying to create an extended partition. In GParted, I shrunk the size of the existing partition and now want to create a new EXTENDED partition in the free, unallocated space. GParted only lets me create a PRIMARY partition. What am I doing wrong here?
Here's what I've got right now:
You can actually ignore the flag for the swap as "boot." That was me just messing around trying to get it to work. I've removed that flag. Not sure how the question of boot affects all of this...maybe it factors in somehow.
To install ubuntu 10.04, I've tried to create partitions on my hard drive, and an external hard drive. Both have failed. I have apparently exceeded the max number of partitions on my hard drive (came with 4 on it. Recovery, OS, and 2 others I don't want to mess with.), and the external hard drive won't let me shrink the NTFS volume to create space for a new partition. Can I get steps to create a new partition, preferably on the external drive (it has more space). My computer is a dell inspiron 1525 with a 225 Gb hard drive, And my external drive is a windows system Seagate 1 Tb Hard drive (I've checked, external drive works with ubuntu).
View 9 Replies View RelatedI have been using Ubuntu 10.04 for awhile now, and I wish to create a partition for Windows 7 so that I can dual-boot. I know you all are cursing me right now, but I have no choice. I run too much high-end software for business purposes that I need to.
I have dual-booted before, but that was when I had windows xp on a primary partition, and I seem to recall that was necessary. I dual-booted ubuntu afterwards as a trial basis, and then I completely switched to Ubuntu 100% for the last couple years. Unfortunately I need to go back. Is it possible to create a file partition for windows as a secondary partition without wiping all my data?
I'm trying to install XP Sp 3 on my comp which is running Ubuntu atm. But when I tried to create a partition after I clicked "Apply" I get this error :

I was doing an exam the other day and they wanted me to create a partition /dev/hdd5 so I saw there was a /dev/hdd so when I created the partition it obviously named it /dev/hdd1. How do I get it to be hdd5?
View 3 Replies View RelatedI am a newbie to Linux. I am currently running Windows 7 and looking to have a dual boot system. I started by going through the Windows Control Panel to shrink the current partition. This left me with a 7.75 GB recovery partition, a 100 MB system partition, a 160 GB partition for Windows and 130 GB unallocated.
My question is (1) do I need to do anything with that 130 GB partition that is unallocated and (2) when I run the OpenSuse CD to install, how do I make sure it installs to that 130 GB partition?
How to create a partition in terminal, like using fdisk.
How to do it in command line,what are the commands to be executed and if there are best practices that I should observe when doing it.
I am a newbie to Linux and I am using CentOs. I am trying to create a new partion on my CentOs VM. I create a new primary partition using fdisk (I use the command fdisk /dev/hda). After I create the partition and use partprobe to write the partition to disk, I try to give the new partition a label. So, I use the command e2label /dev/hda LABEL=test
However, when I enter the command e2label /dev/hda3 , it doesn't display the label for the newly created partition. Am I doing something wrong here? Is the syntax of the e2label command wrong when creating the label for the new partition? Did I miss a step after writing the new partition to disk.
can we use partition typ 83(linux) for creating a LVM partition.
View 2 Replies View Relatedi already reserved the space for the partition, from what i have read so far, it has to be FAT32 or NTFS. also my major question is how i would be able to point both OS to save my files to the 3rd partition i am creating for sharing. cos in my experience, windows likes to store files in its home partition without even giving u an option to see other partitions in ur system, ubuntu at leastb allows me see the other partitions on the drive.

I have a laptop with Windows XP and because of a few programs I want to keep it on and dual boot with Ubuntu. I have created a boot partition at the beginning of the harddisk because I had broken the 137gb and cant keep Ubuntu at the end and still make it bootable.
The separate boot partition is at the beginning of the disk and mounted as /boot in the installation.
The system still cant boot into Ubuntu, but at least grub shows up with a decent menu and I can choose Windows. When I try to choose Ubuntu it says that it cant find the specific drive. The UUID is the same as the boot partition
So what should I do now ? Should I change fstab and move some files to the boot partition ? Id rather not move the entire Ubuntu partition to the front.
Here is my boot info script

I'm running UbuntuStudio 9.10 on my Toshiba Satellite A40 Laptop... it's perfect and I love it... but, I installed it cleanly doing a reformat of the drive, and with no partition - so using as much of the newly replaced 80gb drive as possible.Now, if I want to create a partition to install WinXP as a dual boot, 1) can this be done? 2) what do I use to do it?
View 9 Replies View RelatedRan into a roadblock in trying to create a new /home partition on my hard drive. Used Gparted to create the new partition,when I mount the new partitions and checking to see if they are mounted I see that they are. I then cd /old/home and then I use the command (find . -print0 | cpio --null --sparse -pvd /new/). I get the following on all of my files:

I'm about to reinstall Ubuntu and one thing I'd like to do is create a separate partition for /home. also what are the exact benefits of that?upgarding ubuntu doesn't necessarily delete your files right?is it just as a security measure in case the kernel becomes corrupted?
View 8 Replies View RelatedI am dual booting windows 7 and ubuntu 10.04 using grub. I am using a 1tb samsung hard drive. Ubuntu has 750gb and windows has 250gb. I want 500gb of my HD to be FAT32 so I can put all of my music, pictures, and videos on it. I don't have more than 100gb used on either partition.
I have done quite a bit of searching and browsing, but I can't find a good step by step guide to do this. I am guessing I need to figure out how to use fdisk?
I have two 500gb hdd. One of them crashed (the one which i used windows on) and its now getting sent to the warranty people. On my other hdd i do not have any OS installed, it's just one 500gb NTFS partition, i have there just some personal important stuff. I want to install ubuntu 10.10 x64 on it. I understood that when i will do this, from the available free space it will be created a new partition.
I have tryed to get along with linux a few years ago and i failed... Can you tell me if i will be able to delete the partition ubuntu is creating and merge the unpartitioned space back to NTFS without formating the drive? Also how big are the risks of losing my data when i try to install ubuntu and when i will try to go back to one big NTFS?
I am running a dual boot of WIndows XP and Xubuntu 10.10 and I want to have an NTFS partition so I access files in both OSs. From what I understand, it has to be a Primary Partition, not a logical one, right? The thing is, GParted doesn't give me the option to create a Primary Partition, only a Logical one inside sda2 (Xubuntu).
P. s.: I am running GParted from inside the Live CD.
I've been wanting to do this for awhile now, But just got around to having the time/energy to do it.Getting a separate /Home partition is my main goal,But Ive got a couple others as well.
I've never really done much work manually editing/extending/creating of partitions, Soo Im going to need really simple, noob-like instructions if possible. I'd love to get this on the first try without having to start all over.. So I come to you first, before I just jump in and start clicking things.

I'm following the book RHCE book (5th edition) by Michael Jang. On the exercise on pg.140, creating partitions, I've created /boot (hda1), swap (hda2) and / (hda3). So far so good.
Next, I'm supposed to make an extended partition, containing the rest of the disk. So this should be hda4, right? But when I try to create either an LVM, or RAID partition, it creates hda4 AND hda5 under hda4. Why is that? Am I doing something wrong? The book next asks me to create /var as hda5, so if hda5 is already created automatically above, how am I supposed to create /var?
I have a physical drive of about 40GB, I want to create a partition of 10GB with FDISK on this drive.

I thought using fdisk /dev/hdb is thw way but it confise me because in this i have to give block size or start and end cylinders which is very confiusing, Any idea how to make fixed size partition like 10GB or more.
View 1 Replies View RelatedI made a post about this issue a while back and it's still happening in 10.04 ubuntu, I have 4 disks 2x120gb 1x250gb and 1x500gb, during install I can only see the 500gb HD and none of the other, I get an LVM drive during install for 250gb but that's no good (see attachment)
Now if i run the install with "nodmraid" the raid goes away but it only sees the 500gb I can however see the other drives in GPartion but I cant install to it.
I get the exact same thing in fedora 13 however when I run the install with "nodmraid" I can see all the drives and install to it.
I am so sorry but this is not for me. I cant make this work. I want to install windows xp back in my pc, i just give up with Linux, I lack the expertise to do anything here.
View 2 Replies View RelatedI'm trying to set up a RAID1 partition on my Ubuntu 9.10 workstation.On this dual-boot system, Ubuntu is running from a separate drive (/dev/sdc - an SSD that is quite small, which is why I need more disk space). Besides that, there are two traditional 500 GB hard drives, which have Windows 7 installed (I want to keep the Windows installation intact), and about half of the space unallocated. This space is where I want to set up a single, large RAID1 partition for Linux.
(This, to my understanding, would be software RAID, whereas the Windows partitions are on hardware RAID - I hope this isn't a problem... Edit: See Peter's comment. I guess this shouldn't be a problem since I see both drives separately on Linux.)On both disks, /dev/sda and /dev/sdb, I created, using fdisk, identical new partitions of type "Linux raid autodetect" to fill up the unallocated space.
Device Boot Start End Blocks Id System
/dev/sda1 1 10 80293+ de Dell Utility
/dev/sda2 * 11 106 768000 7 HPFS/NTFS

But so is "Device or resource busy" when trying to create the RAID array. Quite strange.
Update: Could the device mapper have something to do with this? How do /dev/mapper and dmraid relate to all this mdadm stuff anyway? Both provide software RAID, but.. differently? Sorry for my ignorance here. Under /dev/mapper/ there are some device files that, I think, somehow match the 3 Windows RAID partitions (sd{a,b}1 through sd{a,b}3). I don't know why there are four of these arrays though.
