Server :: Creating Partition For Additional Lun?
Apr 26, 2011
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

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 have Ubuntu installed side by side with Win7. My Ubuntu partition was (hd0,6). Then I created one Win 7 partition using Win7 before my Ubuntu partition. Win 7 pushed my Ubuntu partition to (hd0,7).
When I start Ubuntu, I get an error
Code:
error: unknown filesystem
grub rescue>
Now, when I do this

I've been playing with some intel server board and they provide a type of fakeraid which is called Embedded Server Raid Technology 2. Since Intel officially support RHEL and SLES on their servers, they provide drivers/modules for this fake raid (which supports raid 0, 1, 5 and 10). I have installed RHEL before on these severs and redhat's installer has the ability to load additional modules (via a boot command linux dd).
While intel doesn't provide the modules for other operating systems, they provide a library where people can build their own module for their kernel. I managed to build this module called 'megasr' (for now I've built it for kernel 2.6.32-24-generic which is my testbed at the moment but I would eventually build it for box i386 and amd64 for both server and desktop versions) and load it on a system which is installed on a single drive.
We are able to load it successfully and see the raid 5 as a single volume and access it (partition, format and copy data to it) and all its functions (work in degraded mode, rebuild, etc) work fine but my main goal is to actually install such volume as my main boot volume (similar to how its possible with RHEL or SLES). Is this possible? Load additional modules during the installation that will be present after the installation is finished?

I've got two files. They both contain package names. Is there any way I can go through the package list on one file, and search to see if each package exists in the other file? What I'd want to do, is if the package name is found in the the main file, then go to the next line. If its not found then print that package name to another file.
I know you can use diff, but it doesn't seem to be that straight forward. As I understand it diff searches line by line, so if line one doesn't match line one in another file, then it prints it out. That's not exactly what I want.
I just really need an easy way to filter out the additional packages that exist on a new server. If I have a list of packages that aren't on the original server, then i can just delete them.
Not sure if I've made any sense but there must be a quicker way to do what i need to. It would take me ages to scan manually through the package names in each list, and highlight the ones i dont need.

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 debian Lenny as an server I would like for monitoring of some network components ( switches, printers, routers ... ) and at
/usr/share/snmp/mibs I have
/usr/share/snmp/mibs# ls -l
total 1844
-rw-r--r-- 1 root root 17455 2008-12-16 18:22 AGENTX-MIB.txt
-rw-r--r-- 1 root root 36576 2008-12-16 18:23 BGP4-MIB.txt
-rw-r--r-- 1 root root 36959 2008-12-16 18:23 BRIDGE-MIB.txt ....
ls -l | wc -l shows 66, what means 66 differen mibs.
snmp related packages I have installed are as :
dpkg -l | grep ii | grep snmp
ii libgsnmp0 0.2.0-2.1 an SNMP library implementation based on glib and gnet
ii libsnmp-base 5.4.1~dfsg-12 SNMP (Simple Network Management Protocol) MIBs and documentati
ii libsnmp-perl 5.4.1~dfsg-12 SNMP (Simple Network Management Protocol) Perl5 support
ii libsnmp15 5.4.1~dfsg-12 SNMP (Simple Network Management Protocol) library
ii snmp 5.4.1~dfsg-12 SNMP (Simple Network Management Protocol) applications
ii snmpd 5.4.1~dfsg-12 SNMP (Simple Network Management Protocol) agents
My question is, how I can install additional mibs ( for Cisco, Procurve, etc ) for other hw I could have ? What is procedure. I browsed debian package base and I could not find some more packages related to snmp that could supply more mibs.

I believe server section is the best when speaking of RAID stuff...
I have the following situation:We have a DELL T3400 with embedded fake raid on it. I dont know exactly how the system was setup (I wasnt here at that time), but the RAID was enabled in bios and while booting, the two harddrives would be seen as members of intel raid volume0 (RAID 1 mirror). I am not sure if the software raid was actually properly configured in Linux (Fedora 9) and if the OS was reconstructing the whole raid or it was just the bios part that was mirroring the /boot or just some parts of it. Frankly I find these hydrid raids very confusing.Some bad disk manipulation from my part caused the server to crash, but I was able to recover and boot just with one hard drive after using fsck.
I decided to get rid of the raid as it's not the right solution for the application we need it for and decided to go for a traditional single harddrive system and to use Ghost for Linux to clone to a spare disk when backups are needed.So I installed the latest Fedora 12 distribution onto another harddrive and disabled RAID in bios (changed from RAID ON to autodetect, which is the only other option).
Here is what I have now:
/dev/sda has the newly installed fedora 12
/dev/sdb is an empty harddrive that I would use as an intermediate
/dev/sdc is the old harddrive member of intel raid volume0
sdb was partitioned into sdb1 sdb2 and sdb3 and I created an ext3 filesystem on sdb2. The hard drive belonging to RAID volume0 (sdc) has a lot of work done on it and I would like to be able to recuperate the files to the new disk (sda). I cannot mount that old harddrive while in fedora 12, as it sees some unknown raid member filesystem on it probably assigned by the intel raid chip.
So I decided to do it from the other side: to boot from raid volume 0, and from there mount a third intermediate harddrive (sdb) onto which I would copy the documents and then mount the same harddrive from the newly installed fedora 12 and copy those documents from that intermediate harddrive.I can mount /dev/sdb2 from fedora 12 fine and copy stuff to and from it, but not when I boot from the RAID volume 0 harddrive (sdc) with fedora 9 on it. It keeps saying that the partition in question (/dev/sdb2) is an invalid block device.I am stuck here, as my knowledge in this sort of things is very limited.If somebody can indicate me how to recuperate files from that old raid harddrive onto the new fedora 12 drive, I would appreciate a lot.

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).

I 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 :
GParted 0.6.2 Libparted 2.3 Create Primary Partition #1 (ntfs, 74.50 GiB) on /dev/sda 00:00:01( ERROR ) create empty partition 00:00:01( ERROR )libparted messages( INFO ) Partition(s) 1, 5 on /dev/sda have been written, but we have been unable to inform the kernel of the change, probably because it/they are in use. As a result, the old partition(s) will remain in use. You should reboot now before making further changes.

I 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?

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.

i 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.

Ive decided to create a new thread because my old one had become rather complicated and now had a misleading title.
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
Code:

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?

Ran 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:
cpio: cannot make directory `/new//./dan': Permission denied
cpio: /new//./dan/Music/Patsy Cline: Cannot stat: No such file or directory
cpio: cannot make directory `/new//./dan': Permission denied
[code]....
How can I clear the permission denied and copy my files to /new?
Disk /dev/sda: 80.0 GB, 80026361856 bytes
255 heads, 63 sectors/track, 9729 cylinders

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?

I 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.
