Fedora Installation :: Clone System To SSD LVM To Ext4?
Feb 9, 2011
I am currently running x86_64 F14. I am replacing the HDD(s) with one SSD and one HDD. What I want to do is a fresh install but pull all of the packages over from current install. I am planning on backing up /home and all of that so I can just rsync it. One of the issues though is that I currently use LVM. LVM does not support TRIM yet for the SSD. So I was just going to use ext4 and an extended partition for all of my filesystems. Can I just make a kickstart file that will have all of my current installed packages in it and pass that to the install? Seems like I remember that from my RHCE class. Sadly I don't use kickstart enough to remember.

Running Squeeze here. I added a new SSD to my system. Root is /dev/sda3 and I want to clone that system to the new SSD on /dev/sdb1 and make it bootable. I tried:
mount /dev/sdb1 /mnt/ssd_root
cp -dpRx / /mnt/ssd_root
then
update-grub
or
grub-install --recheck --root-directory=/mnt/ssd_root /dev/sdb
but to no avail. I cannot get the new system to be bootable and available through Grub. Part of the problem is that I do not know my way around Grub v2 so well, I could probably manage quite well with legacy grub. So, whats the easiest way to clone a system and make it bootable on another partition? Should I be using debootstrap, and importing/exporting the package list to install the same packages on the new system as the old? or is using cp -dpRx to copy the old ok? How do I make the new system boot?

I see that F11 respin Omega-Pug live CD is available for download. Before I use up the bandwidth, can someone suggest if the file system default installation is ext 4, as in F11 live cd, or can one now choose ext 3. The reason I am asking is that mine is currently ext3, and I would not like to lose my /home partition, with all the stuff that has accumulated.

I have been able to get most of the way through the process of changing from using ext4 back to using ext3, but something is not quite right so my system does not boot properly.
I have a system that was running Karmic Koala 9.10 as a server (no graphical environment). I had two drives using RAID1 with LVM on top, where the logical volumes of oldvg (old volume group) were using mostly ext4. /boot was not part of the RAID: it's on a separate physical drive and uses ext2.
I recently added two more drives and used RAID1 and LVM, and made all lv partitions (/, /usr, /var, /tmp, /opt, /home, /srv) ext3. I used rsync to duplicate the contents onto the logical volumes of newvg (new volume group). I was careful with rsync's option switches, and this part seems to be fine.
I also edited (the new) /etc/fstab and changed the UUIDs of the seven mount points to point to the logical volumes that are part of newvg instead of oldvg, and added new entries to (the new) /boot/grub/menu.lst to refer to newvg in addition to those that I left around to refer to oldvg.
This wasn't sufficient: rebooting here failed, but I went in with a rescue disk, and first updated /boot/grub/device.map to include the new physical drives. I then mounted all the new logical volumes, mounted boot also at its proper place, and entered a chroot of the new system as it should be mounted. Once there, (and after making a backup of /boot) I ran "update-initramfs -k all -c" to rebuild the initrd images that were stored on /boot. Finally, I also edited /etc/mtab so that the two entries that referred to oldvg now refer to newvg instead.
Now, the machine begins to boot from newvg, but the console text includes messages like:
And a bit later,
Now, at this shell if I type mount, I see:
I am actually confused as to why there are only entries for /root and /var in /etc/mtab, actually, instead of entries for all of the main mount points. I am thinking it must be part of the boot staging process, because there are entries for newvg-usr, newvg-tmp, etc. in /etc/fstab.
When I type any of pvdisplay, vgdisplay, or lvdisplay, I get
In fact, even if I run lvm, I get a similar error:
However, if I go back to the rescue cd, pvdisplay, vgdisplay, and lvdisplay do show that all of the partitions from both the old and new volume groups are available.

I have a question about ext4,remastersys backup : I have upgraded from 9.04 to 9.10 via the upgrade button in synaptics, so it means that the files system was not touched, which means that my system is still ext3 as it was when I installed the 9.04. I can make a backup of my system as it is configured right now (that's how i like it) using remastersys.
Can I install my system backup into my machine after formating it into ext4 or when I create a backup using remastersys it must stay in the files system as it was when it was backed up? The issue is that right now the 9.10 responds from some reason a little bit slower than my 9.04 responded (to everything e.g. open/close windows etc...) and I read in the forum that ext4 makes 9.10 run faster.

I have a Dell Mini 9 netbook. The SSD took a dump, so I ordered a Super Talent 16gb replacement. I put it in yesterday, tried to install 10.10 and constantly get errors. The first error, which I haven't had since, was [ERROR 30] Read-only File System. The install obviously failed. Wondering if perhaps the file got messed up in translation, I redownloaded 10.10, reformatted the flash drive (sandisk cruizer 4gb), put 10.10 back on via the program on the Ubuntu site. No luck, but no longer the [error 30]. Tried again using Unetbootin, no luck. Rinse repeat a few times, no errors just a working cursor spinning and spinning and spinning and spinning and.. you get it.
Tried to put WinXP on it just because I was that frustrated, no luck.
Now I'm back to Ubuntu (because let's face it, who wants to deal with Windows, christ they make it so complicated). I'm currently using 10.04 because I was hoping (praying) it might just be a 10.10 thing.
No such luck, now it goes to step 7/7, starts, and 5% of the way thry "creating ext4 file system" it says "the ext4 file system creation in partition #1 (0,0,0)(sda) failed." I have checked the SSD in the Disk Utility, SMART tests are clean. I have gone to terminal and run fdisk and had a smarter person than me look at the copypasta, no errors, I have deleted all existing partitions in gparted and started fresh. I have tried the auto partitioning, I have tried manual, I am going insane. Literally insane. My preschooler thinks I've leaped off the deep end.
Could it be my flash drive? Could the SSD be defective despite the tests coming back clean? What do I need to type into terminal? Is there a way to entirely entirely entirely wipe the SSD to make it fresh-out-the-box clean? I will happily provide whatever you need if it means I can get my husband off my back about this stupid netbook with its stupid tiny keyboard.

My main hard disk died and I replaced it. After installing windows in a small partition in /dev/sda, I thought I will try linux mint and went for it. (I need windows to play AOE, but ubuntu is my primary OS)I didnt see the options properly or some distraction, I choose the "install alongside windows" option probably expecting it to install it in the unallocated partition next to the windows installation. I had completely forgotten my second internal drive /dev/sdb which has the backup data. Linux mint went and installed itself on that drive.
Is there a way to recover individual files from the second harddrive. Now if I boot or open it through live cd, all I see in the linux mint file systems. I want to aleast recover my CV/resume from the second drive. The second drive is a single ext4 file system The old drive is completely dead, it doesnt even get recognized when I attach it to SATA.

I'm new to fedora (still trying it out) but have many years of experience on other distributions -- mostly gentoo. Anyway, I'm wondering if someone can tell me what all is needed to clone a fedora install. I cloned the partitions, updated fstab with real device node entries (removed all the UUID stuff), and modified grub.conf with the same changes (as well as all the normal/misc changes needed in /etc for things like hostname, network, ethx naming, etc). However when I try to boot it complains that it cant find the old UUID.
I thought this might be specified in the initrd but I uncompressed it and couldn't find any reference to the uuid anywhere. Where does fedora keep this UUID information at? Right now I'm just trying to clone a mythdora box to another one but in the past I've configured a single gentoo install and cloned it on dozens of other computers.

I can't seem to get past step 6 of he installation of Ubuntu 10.04. I get the error: The ext4 file system creation failed... on single partition (no raid). I chose ' / ' as the mount point, and have tried with and without a swap drive. I'm installing on a Sony VAIO VGN-NS160D, and the HDD was previously formatted to NTFS. There's no other OS so I don't see any way of getting a command line to try a sudo fdisk..

I grabbed the new lubuntu 10.10 from [URL] but it turns out I'm having a problem installing it on my netbook (Asus Eee PC 1015PED). While installing, this error pops up:

I'd like to clone a partition, and then restore it to a logical volume. I have all three operating systems at my disposal (Mac, Windows, Linux Live CD) What is the best way to achieve this. The partition I am trying to resize is only 200MB, so I can store it on usb if need be.

i recently installed Debian Lenny on my dad's EEE 900A. I initally tried Ubuntu's 10.04 version but it gave me problems with the WiFi function keys. Debian took me a while to configure based on the excellent Debian EEE wiki, and everything's so much saner now.
I installed Debian Lenny using LVM2, spanning the files over the built-in 4 GB SSD and a plugged-in 8 GB SDHC card. I followed the instructions in this wiki to set it up. I was wondering if there's a way to easily clone this system so that if my dad accidently screws it up the in the future, he would be able to restore it back easily. Obviously, he would have to make backups of his documents, etc. on a separate drive so he can restore them back after the cloned image with the basic drivers, partitions, apps, etc. is restored.
Here's the system's info. There are three partitions on /dev/sda (the SSD) and one partition of /dev/sdb (the SDHC card). /dev/sda3 and /dev/sdb1 have been combined to create a Volume Group, called 'vol-1'. 'vol-1' has two Logical Volumes - 'root' and 'home'. The file system on all partitions is reiserfs.

I'm thinking about cloning a system without having physical access to its HDD. Is it possible to simply copy the contents of the filesystem (using ssh/scp) to a freshly formatted HDD (maintaining the source fs-type and -geometry)?

I am new Ubuntu. I have a new Dell Mini10 running that I have configured and running. I want to clone or backup the system at it's current state. I have been looking at the options and Clonezilla seems to be recommended often. Are there other choices that are easer or better? My real goal is to make a bootable DVD that will restore my system back to the point it was cloned.

Thinking of a re-install to remove LV and use Ext4 only. [Root is too large] Can I back up Home from the LV and move it to an external drive. If so will I be able to reinstall and Custom partition so I can use Ext4 and then copy the Home files back to my new Home partition. I have only a small knowledge of LV systems so just want to be carefull.

I have a computer, that has the bad luck to be equipped with buggy hard-drives. Actually, they need a firmware update. This firmware update will probably destroy the data on them. I also want to add one or two other hard-drives to the RAID. What I am looking for, is a tool, that makes a clone of the system as it is now. And then, when I will have upgraded the disk firmware and added the other hard-drives, I just clone the system back from the clone.

I have automated backups running on my ubuntu box using rsnapshot (rsync) basically following this tutorial. My concern is how to restore if everything is lost. Since it does not seem that I can backup the entire drive and that I have to choose individual folders and some like proc/ cause problems.
Currently in my rsnapshot.conf I have (see below). Is there a way to just clone the entire drive? Or should I not do this? Questions:
1, Can I backup in a way such that it is a clone of the drive so that it can be swapped with the current drive?
2, If not yes to clone, If I had a total drive failure would I install a basic ubuntu and then replace all the files with the backups?
3, Anything I might not know about that I should.

I booted into the Fedora 11 on my netbook, and used the desktop icon to install to hard-drive. I specified to use "Free space", and hit next. From there, it just stalls. The "Install Fedora" window does nothing, and I'm going on a half-hour now of nothing.
Tried three times, still nothing.
The first time I tried, I chose to replacce old linux installation (ubuntu), and when I told it to install Fedora 11 root as ext4, it said the boot can't be ext4... so I chose ext3 and it said root device must be ext4...

It has crashed or failed to install on a known good system for the 5th time now. I have never had that problem with fedora before. I am now installing with ext3 instead of ext4. I am hoping for better success with it and will update. I was able to try MinGW with WINE before the first crash and I liked what I saw there. Only hoping to be able to get a good install this time.

I have a 16GB Ubuntu Webserver running on a Transcend SMART CF chip (Yes I know all the reasons not to). I want to move that entire system (OS, Files and structure) to an external bootable HD that will probably be closer to 100GB. What's the easiest way to do this and have it be plug and play. By which I mean I can then plug the drive into a new system and boot it up just as it was running on the old system.

I have installed grub.efi in the ESP partition which is able to load ubuntu 9.04.I think it works with fedora 11 x64 as well. And I tried to install fedora in the partition which was used to install ubuntu. But the installer keep telling me that ext4 partitions are not bootable. But I don't need to install a boot loader on that partition

Is that possible, I mean when I upgrade F10 to F11 with yum upgrade is there a way to 'upgrade' the filesystem to ext4 for example (with the exception of boot partition)? Or I have to reinstall fedora like new?
While changing the filesystem can I do it by parts? what I mean is for example: I have 2 partitions like '/' and '/home' with ext3, so I backup data in '/home', change '/' to ext4 then mv files from '/home' to '/' and change '/home' to ext4 and finally mv those files from '/' to '/home'. Is that possible?

I upgraded F10 to F11 successfully.
Then I convert the / partition filesystem by the following steps:login as root user in multi user mode read [url], and execute tune2fs -O extents,uninit_bg,dir_index /dev/mapper/VolGroup01-LogVol00 modify /etc/fstab, change the type of / to ext4
reboot
(because fsck say running it on a mounted filesystem can cause filesystem damage, so i decide to reboot to single user mode first. maybe it's a mistake here) try to boot F11 to single user mode, failed
reboot from a SystemRescueCD-1.2.0 LiveCD
run e2fsck -fpDC0 /dev/mapper/VolGroup01-LogVol00 in SystemRescueCD-1.2.0 LiveCD, no error reported
reboot
try to boot F11 normally(multi user mode), but it failed at: EXT3-fs: dm-0: couldn't mount because of unsupported optional features (40).
I tried rescue mode of Fedora-11-i386-netinst.iso after these steps above. The / partition can be found and mounted to /mnt/sysimage correctly. I can read/write files in / partition, and i can even yum new softwares in rescue mode, but it just can't be mounted when booting.
