CentOS 5 :: Swapping Hard Disks - Should I Try Using CloneZilla, Or PING Or Should Ghost Be Able To Cope??
May 21, 2009
I have built a CentOS machine just for playing around with and learning, however for the last few days I have had a couple of disk errors. So I want to replace it with another, and retain the data. I'm fairly new to Linux, but figured you could just image all partitions to another drive, so I tried this with Ghost 11. It imaged OK, but wouldn't boot - it went straight into Grub. What do I do here?
The original disk is just an 80gb IDE, the replacement disk is a 40gb IDE. I made sure it was in the same position on the IDE channel when attempting to boot from the new one (primary).I used Ghost to resize the partition down so that all partitions fitted onto the newer smaller disk.I didn't have much time to investigate further last night, so is it recoverable from the Grub prompt or have I gone about this the wrong way? Should I try using CloneZilla, or PING or should Ghost be able to cope?

Is there a software utility out there for Ubuntu that can make a backup of the hard drive my Ubuntu 10.4 is installed on?
I have used Symantec Norton Ghost for Windows before. Is there a similar program for Ubuntu? I would also like to use the backup of the hard drive to reinstall on the same drive after a format.
Also, what would happen to the GRUB loader if I were to copy it back onto the hard drive?

I'm trying to make a simple task as complicated as possible, so bear with me.
I'm going to force a friend onto Ubuntu soon, and the biggest requirement is photo management.
He wants his extensive photo library backed up, and backed up some more, and then when all feels safe, backed up even again.
Currently, all his photos reside on a 4 disk striped RAID array, based on his cousin's recommendation. The intent was a RAID 1+0, but they failed, and that needs to be fixed immediately.
So, instead of going with more mirrored hard drives in a RAID, which I know Ubuntu will do just fine, I'd like to simplify and just do manual backups of each hard drive.
So, I'm looking for a program that could possibly be set up to automatically back up a hard drive onto another hard drive on a weekly basis or something like that. Ultimately, doing a manual copy/paste of the data in the drive could work, but would be time consuming.
I'm scared of RAIDs lately because of a recent fiasco with a BIOSTAR motherboard and how it set the RAID mirror on a set of hard drives for a Windows load that rendered the harddrives basically useless for anything but a RAID mirror, with that motherboard and a Windows load, and I almost lost a lot of data because of it.
I'm also not sure how well Windows would recognize a RAID partition created in ext3, if he ever wanted to go back to Windows.

I have two servers (A and B) which are identical. My idea was to have a software RAID 1 with both of them running and if server A craps out I wanted to swap the hard drives from server B into server A. When I tried to test this idea the network driver doesn't seem to want to cooperate. ifconfig gives nothing and I can't figure out why. From googling I've read that a network card has a unique ID on it (I'm assuming their talking about the MAC address) and is used in some config files which is why swapping hard drives gives two different MAC addresses and confuses the system. If that is so would anyone know exactly what config files the mac address is stored/used in? That way I can make a backup of those files and swap those out if I ever need to swap out the hard drives.

I have installed Ubuntu 10.4 worked fine, and Clonezilla (including configuring it) -- (though my /etc/networking/interfaces seems to give an error in line 2 I have the following questions)I have installed a second Hd (250Gb) ... and I have formatted it with gparted so it mounts fine and I am able to see it ... is there any way to make it a permanent mount and have Clonezilla use it to store images on it? ... The first HD was formatted LMV during the Ubuntu installation.

Whenever I'm dealing with large numbers of computers that need to have identical windows installations put on them, I love using Symantec/Norton Ghost to image the NTFS partition (just making the .gho file the size of the disk I've used, instead of the 160/320GB full volume size), and then uploading it automatically to a windows share.I'd love to be able replicate this exact process with Ubuntu. I have one computer that's ready to go, and a few dozen more that I'd like to quickly get that same image on.
I've heard that there's a command called dd that can make disk images, but I'd really like some sort of boot disk that can allow me to make an image, save it, then run the boot disk on another computer to allow me to reconnect to the server and dump that image on that computer. Ghost 4 Linux doesn't have a network/server component, I think.even if such solutions cost money, I'd love to know if they exist or not.

I have two internal harddisk. Harddisk 1 has ubuntu, fedora installed and harddisk 2 has ubuntu installed. I normally connect either one, and use it. How can i always keep connect both harddisks, and at the start, select from which harddisk to boot? Or it's not possible?

I notice a bunch of weird what appear to be hard drive related error messages on my Linux server:
Code:
May 16 19:07:38 ghost kernel: [ 3495.452698] ata3.00: configured for UDMA/33
May 16 19:07:38 ghost kernel: [ 3495.452706] ata3: EH complete
May 16 19:07:40 ghost kernel: [ 3497.380640] ata3.00: configured for UDMA/33
May 16 19:07:40 ghost kernel: [ 3497.380648] ata3: EH complete
May 16 19:07:44 ghost kernel: [ 3501.732973] ata3.00: configured for UDMA/33
please use /proc/5073/oom_score_adj instead.
I don't know if this could be an indication that my hard drive(s) are about to fail. Can someone tell me if there's a way to test the drives or understand what's causing this error?

I'm trying to "upgrade" from ubuntu 9.04 to ubuntu 10.04.2 via a clonezilla (using a maverick usb clonezilla software with it's vmlinuz and initrd.img). but this clonezilla is not from a bootable usb flash drive, usb drive or CD, it's from the hard drive.
Here's what I have:
1) one 500gig drive with a primary partition under LVM. this partition has a 490gig root partition (ubuntu-root) and a 10 gig swap partition (ubuntu-swap_1). It has an extended partition (/dev/sda2) that's not under LVM consisting of one logical drive (/dev/sda5) that is the /boot partition.
2) I've upgraded the grub to grub2 (version 1.96) which has better features.
3) I've deleted the swap and reconfigured this partition with a name of (livehd) and it has an ext3 filesystem. I've copied the clonezilla software to this partition which also has the ubuntu 10.04.2 image that I want to restore to the root partition.
4) I've modified the existing grub2 using the 40-custom file so that the grub menu has the "Clonezilla Ubuntu 10.04.2 upgrade" entry in it.
5) the initrd.img from clonezilla has LVM support since I opened up the image to a directory using "gzip -d -c /boot/initrd.img|cpio -i" to check it.
6) grub2 sees the (ubuntu-root), (ubuntu-livehd), (hd0,1), (hd0), and (hd0,5) devices and can list (ls) their directories

I'm going to buy a new system, and I have 2 SATA hard disks from my old system. One is installed with a Linux OS, the other with Windows Vista.For the Linux hard disk, will I be able to simply use these 2 hard disks on the new system and boot up, retaining all my data? If not, how do I transfer the data from my old hard disks to my new hard disks? My old system is faulty (no signal to monitor), so I can't just copy everything directly using, say, a portable hard disk.

I'm using SUSE11.1, and connected to my system, a DELL 7500, a 1.5 TB Buffalo external HD. I partitioned it in 4 sectors.After connection, nmediatly the mounted disk would appear on the screen,(each partition with its respective name), and could use it as any other folder.To unmount the external Hard disk, I just ejected each partition, and had no problem. I used the same HD with my Mc, and things were all right, I used to backup automatically the Mc. However after having been using the system in this way for more than half a year, suddenly the hard disk began to rattle...and the SUSE system on the DELL, nor the Mc can mount the external hard disk any more. Thus, the partitions can not be mounted any more. When I cd to /media/ in the SUSE, the names of the partitions appear, but they seem to be empty..On the Mc, going to /Volumes/, before the problem appeared, the names of the partitions were there... but now, they are no more and the automatic back up either.So my question is, how to mount the disk, if it needs mounting... or how I can recover the partitions and the data therein... I am clueless, after two weeks trying to solve the problem..

In Fedora when we double click the Partitioned Local Hard Disks then we have to give the root password otherwise it will not open. Is there any way to read and execute the Partitioned Local Hard Disks without giving the Root Password.

I am booting Slackware 13.0 on an X86 from a (master) ATA hard drive. I have added a second (slave) hard drive that contains an installation of Slackware 13.1. This works in so far as I can boot 13.0 from the master drive, then mount the slave drive and read and write files to it. So the hardware is basically working.What I want to do is configure lilo so I can choose to boot either 13.0 or 13.1. So far I have not gotten this to work.
Under 13.0 the slave disk appears as /dev/hdb. The root-partion for 13.1 on the slave is the first primary partion on the slave, and appears as /dev/hdb1 when viewed under 13.0. What stanza should I add to lilo.conf to make the slave 13.1 bootable?

I thought that alignment of 4096-byte sector Advanced Format hard drives was automatically taken care of via Gparted or Disk Utility until I bought a Hitachi HTS547575A9E384 (Travelstar 5K750) and saw that Disk Utility showed my partitions to be out of alignment. I then realized that my WD, which I had bought a few months ago, probably had its jumper set to emulate a 512-byte sector legacy drive (512e) and is probably not set to the AF setting.
Straight to the problem.
I've searched many sites, some of which suggest using fdisk (others the proprietary software of the hard drive's manufacturer). It is essential that one change the arguments prior to changing the partition table as there is no way back (yet, as far as I know) without having to move data to another drive and starting all over:

the hard disc has two partitions, one is 156gb ntfs, currently with windows xp prof sp2, and I am trying to install linux to the second partition, also currently ntfs.I am not a total newbie (i used fedora 10 last semester and ubuntu the semester before that). I have tried installing ubuntu9.04, fedora 10, fedora 11, and opensuse11.1 to this computer, and every time the installation probes for hard disks it comes up with zip, unless I have my external disks connected. Otherwise "No hard disks were found for the installation. Please check your hardware!"with OK button.
I also tried with gparted to see if I could find the hard disk, and still had no luck. I googled my problem and found others with similar problem but no satisfactory solution.does anybody have any idea what could be wrong and how to fix it??

A few years ago I built a small Slackware system and, for storage, I used using a 2Gb Compact Flash card plugged into the primary IDE interface. Initially, I made a bootable CD rom, booted the new system from that, copied the file system to the CF card and then ran LILO to install a boot sector on the CF 'disk' /dev/hda. That all worked well enough.
The only trouble is that the CF card, being an early one, is rather slow and so I've just bought an Innodisk 2Gb Disk-on-Module which ought to be much faster. I have plugged that into the secondary IDE interface, I've run cfdisk to make a partition, formatted it using mkreiserfs and copied all of the contents of the CF card on /dev/hda to the new device on /dev/hdc. So far, so good. But...Now I need to run LILO from the existing CF card in /dev/hda to put a boot sector on the new /dev/hdc. Then I want to move the new device from /dev/hdc and put it in /dev/hda once it's bootable.
I'm stuck to know how to configure LILO to install a new boot sector on /dev/hdc. I don't appear to be able to make LILO understand what I'm trying to do. If I change the line 'boot = /dev/hda' in lilo.conf to 'boot = /dev/hdc', LILO aborts with an error message.

I have installed xp at the main hdd. It has 3 partitions. Then I installed Kubuntu 10.04 on the slave hdd. When I boot, it doesn't recognize kubuntu. When I searched at My PC in XP, didn't recognized the slave hdd. I switched the hdd (slave to master and viceversa) and it didn't go well either.

i have got a very strange boot problem. But first: I have openSUSE 11.4 with kde installed. I have the amd64 dual core cpu and 2 hard disks. I was able to boot from both of those disks (on the second disk I have openSUSE 11.2 in case something goes wrong with the first disk). Then I decided to install openSUSE 11.4 from DVD to a usb key (just like I would to a hard disk). I succeeded. I did not involve any partition of the hard disks in this install. But now I can not boot anymore from any of my both hard disks although bios finds them it did before. After bios I get the following message: Loading stage 1.5 error 21.
Error 21 means: Selected disk does not exist. This error is returned if the device part of a device- or full file name refers to a disk or BIOS device that is not present or not recognized by the BIOS in the system But I am still able to boot from usb key. I have even modified the menu.lst from the usb key to boot openSUSE 11.4 from the first hard disk. This works fine. I have also tried to install grub again on my first hard disk with grub.install.unsupported and with yast2. But installation stops with an error message like "hard disk not found by bios".

I have a laptop HP Pavilion, on which I installed Ubuntu 10.04. I erased the whole disk and used the option manually define the partitions.
Here is my partition table given by gparted:
Partition File system Mount point
unallocated 1 MB
/dev/sda1 vfat /windows
/dev/sda2 ext4 /
/dev/sda3 extended extended
/dev/sda5 linux-swap
/dev/sda4 ext4 /home
I installed Ubuntu and everything went fine. But now I want to install WinXP from an original Microsoft CD-rom and I get the follow error:
Unable to install windows, no hard disks found, contact your dealer (or something like that, it is translated from Dutch).
I tried everything, formatting my hard disk with gparted NTFS, formatting mkfs.vfat, with no luck.

First and foremost, I really appreciate this newer release of Ubuntu 10.10. My boss wanted to use SLAX, but I had great experience with 8.10 and I have installed 10.10 on laptops and netbooks. on with the challenge for the day: I have configured a user's profile on 10.10 to startup Firefox in kiosk to go to our secure portal. The problem is I don't particularly care to REDO configure a user's profile session over and over.
So, if any of you whiz kids out there can come up with a better way to copy a user's profile...particularly the files that are used for Mozilla Firefox so that I can just copy and paste the files onto another hard drive with a fresh 10.10 that would be great.
The ONLY issue I have working with Linux is that I can not rapidly deploy my settings I have set for 'user' as I can with Windows. I am sure if there was a way to do this, deployment of Ubuntu 10.10 would go MUCH faster. As it stands, if I am able to pull this off...there will be a potential of removing Windows desktops. Which is fine for me because I can manage desktops a little easier on this platform than Windows.
This is what I have installed in Ubuntu:
IcedTea (for Java plugin for Firefox)
Profile Editor
R-Kiosk
All those work great with Firefox, but getting those installed on a new system is a bit daunting.especially when some users suggest doing cloning when in reality...I plan to do the install via LiveCD and THEN hopefully create the user on the fly in Terminal and copy the user files needed off a flash drive into the home/user folder

The secondary disk is a Samsung HD103UJ with old sector-style (512B). Is it possible to set up a RAID 1 containing a partition with advanced factor an a partition with old sector-style or do both partitions have do be in the same sctor-style?

Coming from Fedora, I had a Web/Mail/SQL server with 2 hdd's. One (sda1) was the one with Fedora on, and all backups were on sdb1.
Now, I started having issues with SDA1, so I started copying files to SDB1. 2 weeks later I noticed similar issues, and started copying new back files to SDB1. But once I started doing this I lost connection with the server.
Turns out that (in rescue mode) that I couldn't access SDA anymore, it couldn't even read stored data on it, etc. It didn't show up in fdisk anymore either.
So after a lot of trying I asked to replace the disk and started installing Ubuntu 10.04 LTS on it. After having installed everything, I tried to restore one of the MySQL backups that was on the SDB disk, but halfway I started getting errors. I stopped the restore and did some other stuff that I wanted to take care of first (apache2 config etc.).
I then tried to reboot to be sure that that was working as well, and then the problems started. I couldn't access the server anymore, and in rescue mode (which is a live cd my host provides, it's a dedicated server btw.) I didn't see SDB anymore.
I told them this and now after they told me that they managed to get it back, I went into the rescue mode and tried to recover bad blocks with the e2fsck command.
Code:
Trying to restore this bad superblock doesn't work. I've tried for almost all of them:
Code:
e2fsck: Attempt to read block from filesystem resulted in short read while trying to open /dev/sdb1
Could this be a zero-length partition?
What are the chances of TWO hard disks failing? Surely there must be something else wrong? Did a bad driver (which would be weird, since I didn't do any updates like that) screw both of my hard disks up in Fedora?
Also, I must note that when I tried to copy the backups from SDB1 to SDA1 (the new one). I got a read only (??) error, and some other I/O errors.
Just for information, I'll show fstab and mtab as well: /etc/fstab
Code:
Code:
I haven't added the sdb here yet, but it was here in Fedora so that can't be the problem.
And this is /var/log/messages when the problems emerged
Code:
Then on the ubuntu forum they proposed me to do this:
I ran smartctl and it gave me this:
