I have Three disks installed, one SATA and two SCSI disks.
SCSI1: boot + RHEL3
SCSI2: home
SATA: RHEL5
I want to create an extra partition on the SATA disk without re-installing RHEL5. Is this possible?
On my embedded linux box, running on Linux Kernel 2.6.9 embedded with BusyBox utilities.
An Objective are follow:
1/ To figure out how many partitions are on the hard disk
2/ Create a extra partition about 10GB size on the hard disk
3/ Format the partition and mount var on that partition
Only utility to perform above operations I have "sfdisk" utility from BusyBox collection. Which get installed at the time of image flash in to ROM (8mb ROM size). The following is the root directory structure where hdd as a directory mounted /mnt/hdd1
Code:
~ > ls
bin etc lib proc sbin sys var
dev hdd mnt root share tmp var_init
Within /bin sfdisk utility can be used which I tried but no avail.
Code:
~ > sfdisk -l /dev/hda
/dev/hda: No such file or directory
sfdisk: cannot open /dev/hda for reading
~ > sfdisk -l /dev/sda0
/dev/sda0: No such file or directory .....
Can SATA 3 (SATA III) Hard disk be run on motherboard which only supports SATA II, except sacrificing the speed (throughput)?

The installer recognizes it as well, but the partition area is blank and the option are greyed out. How can I go on? BTW, on the disk currently Fedora 14 is (fresh) installed and working fine, but a software install script is written specifically for Ubuntu. That's why I need to change to Ubuntu and it's no hardware problem.

I want to configure Name Server i.e., DNS to my red hat linux box in a production enviromnt.The ram is 2 GB and Hard Disk size is 200 GB. How much space should I give /var, /usr, /boot, /root and home partition. May be I am wrong in partition point of view while installing fresh red hat but to install for home purpose and server end is different. So kindly guide me the hard disk partition size to ready it for name server.

When I install RedHat, I have to use 'linux dd' to use the HP provided driver (http://h20000.www2.hp.com/bizsupport...5&mode=4&idx=0) and that works fine during the installer, the GUI during the install sees the RAID just fine, it sees one volume, calling it the HP Volume. However, when the system boots after the install, the RAID is gone, and it's now seeing two drives, /sda and /sdb:

The default partition manager which OpenSUSE DVD 11.4 uses (Expert Partitioner) is not creating any logic partition with / mount because another system is already using it, is there anyway to fix this?
View 9 Replies View Relatedextended sata partition shrunk at 15 partition limit, how to re-enlarge i hit the 15 partition limit, forgetting it now exists for sata drives, thinking i would add more. upon creation of the 15th, it squished the end of the extended partition to meet the last logical partition, leaving a large unallocated portion after the extended partition, which seemingly nothing can be done with, just sat being wasted space. i have since deleted a few of those partitions, but so far have still failed to find a way to recoup the unallocated space back into the extended partition.

if necessary, i'll do it the painful long winded way of backing up and starting the extended partition again from scratch, but i really rather wouldnt have to do that. i'm sure there must be a way of telling the extended partition to once again reach the end of the drive.

View 2 Replies View RelatedLet's say I'm using one of those PCs that uses a SSD flash drive in place of a more regular HDD.
Say I burn my favorite .iso distro and install it on this PC. I install my favorite applications and seek out and install any missing drivers and generally tweak the system like you do. When I am finally happy with it, I make an image of this installation to an external USB drive.
Now, say 9 months later some of those SSD blocks have gone bad because they were erased too often. They're no longer usable. Also, because I'm a sloppy person who can't be bothered to delete redundant stuff and run make-cleans and so forth, the disk is getting pretty cluttered and takes longer and longer to do stuff.
I decide the obvious solution is to remove and save any data I need to keep, then just over-write the disk with the image I made 9 months earlier.
The question is: will the firmware be smart enough to re-map my incoming image to avoid these bad blocks on the SSD? Or am I going to wind up with some parts of the image being located on bad areas of the SSD?
im working at a corporate office with Server: RHEL5.1 Database: oracle in /var now the /var partition is out of space they want to add the fresh hard with with 500GB n want to do lvm in that disk. the /var partition is normal partition before.

Since the partition of windows7 (C: ) where wubi was installed was too small, I decided to reinstall wubi into another larger partition (E: ), keeping the old root.disk. Sadly when I replaced the root.disk ubuntu cannot boot, the loader says that there is no root.disk file, although it's there... I guess there is some kind of checksum about the virtual disk toward the loader is poiting... So how can I have my old ubuntu installation back?? I still have the old root.disk.

I'm running Redhat 5 which is running as an email server with Lotus Domino 8.5. Its a VM on ESX 3.5. The server was running out of space to so I added a new hardrive and mounted it to /domino/mail2, everything was fine for a couple of days, but then the machine became unresponsive, I couldn't even see anything on the console screen so I rebooted, it then did a file check and everything came up fine. This has now happened 2 more times over the past few days, I haven't seen any evidence that the extra disk is the problem but if I can't find anything else I will remove it and see if the problem goes away. There isn't really a consistent time it occurs.
Here's the output of the logs from the last time it happened if anybody who know more about this stuff then me ( which isn't a lot) wants to take a quick look as see if the problem is obvious or what I could be trying.

I am in the process of creating a RHEL5.4 custom iso image with minimal functionality. Have gone through a lot of articles over the net and it seems that there are no proper documentation of this process as most of the utilities earlier are not supported.
Following steps were performed :
1. Mount the RHEL5.4 DVD ISO and copied all contents including .discinfo[very important] to a temporary folder [/iso/MODIFIED_ISO/].
2. Edited comps-rhel5-server-core.xml [earlier comps.xml] under /iso/MODIFIED_ISO/Server/repodata under the root directory to only include necessary packages.
3. Removed the unnecessary rpm's from Server directory
4. Created metadata of modified packages, goto root directory of copied folder [in my case /iso/MODIFIED_ISO] and execute :
5. Create the iso :
After performing the above steps, I tested the iso on a virtual box, but checking the error console seems that there are some errors related to dependencies.
Have written a short script to check for the dependencies for the remaining rpm's, executing "rpm -qpR <RPMNAME>" for all rpm's on an already installed box. This would list all dependency packages.
I have a /home partition at /dev/sda3 and I am currently in Gparted. I wanted to know if I am supposed to re-identify it somehow when I re-install ubuntu on /dev/sda2.
It seems to me that it would try and create a new home directory on /dev/sda2 unless I tell it otherwise. Is this correct? I just want to make sure I don't do two things...
1. End up with 2 home directories
2. Delete my existing home directory at /dev/sda3 (with my files)
I have triple boot machine Windows 7 + Ubuntu + Mac OS X in a single HDD.
Windows 7 -- /dev/sda1
Ubuntu 10.10 -- /dev/sda2 (In same Partition grub 2.0)
Mac Snow Leopard -- /dev/sda3
I have installed GRUB 2.0 in same partition where current ubuntu is installed ie /dev/sda2 and basically Windwos Boot manager is installed within MBR.. & I have added GRUB 2.0 and Mac OSX entry into windows boot manger with some freeware from windows 7. So practically when I start my computer First Windows Boot manager comes up and asks me which OS to start first. I set up this type of installation with the thought that when grub 2.0 is not installed within MBR, I can format the whole /dev/sda2 partition without any difficulty and reinstalled any future release distro of ubuntu. So is it practically possible? If I format /dev/sda2 and reinstall new ubuntu release there.. Old grub won't affect the installation of new one.
I deleted the wrong line in grub.conf, and now cannot boot into my Windows Vista anymore. I really need to get it back right away, I am trying to do my taxes, and they are on there, and I can't get to them. I added this to grub.conf, but no luck.

I have Kubuntu 11.04 64-bit installed (software upgrade from 10.10) and I have a separate /home partition. I want to encrypt my /home partition (and perhaps the swap partition as well) but I don't want to have to reinstall Kubuntu. (Mostly because it was a software upgrade and I don't have an 11.04 disc.) I found a tutorial for Encryptfs via one of the stickies that mentions post-install migration, but it says that using Encryptfs on a separate /home partition is more complicated than if it were part of the root partition and that the CDs don't have any software to preserve and configure existing encrypted /home partitions. (Granted this tutorial is made for 9.04, so things may have changed.)
Also, this tutorial makes it sound like if you have your /home directory encrypted that the encrypted data is stored in a folder on the root partition. Is it done the same way if the /home directory is on its own partition? Because I don't think my root partition is large enough to have all of my /home data. (I purposely kept it small because the root partition doesn't seem to get very large.)
How to see/scan new EMC SAN lun/disk in RHEL 5?
View 1 Replies View RelatedCompiz settings, my entire GUI would freeze up after the startup splash. It did the little ubuntu jingle and so on but wouldn't actually load up the desktop. I would've booted into recovery mode and deleted the settings that were messing it all up for me, but pressing ESC during grub did nothing! So as a last effort I reinstalled Ubuntu (Karmic) from the live CD on the first partition only, but I don't know how to make the second partition (with my old /home directory) the normal /home directory. The instructions linked above seem to require having done the whole process of moving the partition (so as to create "old" and "new" dirs, etc.).
So there are really two problems here: 1) How does one restore things to normal when a few too many cheeky moves with the desktop effects turns everything to pot? And 2) How does one reinstall Ubuntu with a separate /home partitions

I have a SSD Harddisk with both an usb and Sata connection, and I want to be able to boot both from usb and sata but I can't make it work. When the disk is connected with sata anything works fine but when I connect it with usb instead, Fedora seems to boot but then it gives me an "No root device found" error and just sleep forever. This happens even if I install fedora 13 while the disk is connected with usb. I am running Fedora Core 13. I changed my fstab to
/dev/sda2 / ext4 defaults 1 1
And the disk is still booting when connected to the sata controller. So far so good. But if I boot from the usb connection, it still give me the same "No root device found" message. Even more odd is it that if I boot my fedora core 13 dvd, and choose "rescue installed system" it can't detect the harddisk when connected to usb. And there is no /dev/sd* or anything similarly which could look like a blockdevice. Did redhat forget to include usb drivers in their rescue image for Fedora core? I just tried the disk on an other system, with exactly the same problems.
I have now added the LABEL=myroot line to fstab(I guess it have to be uppercase to work) and the harddisk still boot fine when using sata, but it still can't boot using usb. I begin to guess that redhat forgot some usb drivers In fedora Core 13, because the system can't see the harddisk when booting the dvd and entering rescue mode. blkid don't show any harddisks at all and there are no block devices in /dev/ which might be my usb disk. Is it possible to find the uuid of partitions if id add the usb harddisk to a windows computer, and more important: will this be the same uuid as linux will se.
I bought 2 new 1,5TB sata disks for my server. But when I plug them in my debian gives a error message: ata2: SRST failed error -16
The debian runs from an old 500GB ide disk and a 160Gb ide disk for the home dirs.
I tried antoher cable, but that is not the problem(or is that other cable also broken...). I also tried all sata modes in bios, auto, enhanced, sata-only. I also tried booting an ubuntu 9.10 live cd. But in gparted the disks won't show up.
Is it possible that the sata controller of the motherboard is to slow.
