Moving Fedora system to new disk

[Timothy Murphy]

I'm planning on moving the Fedora-20 system on my laptop
to a new hard disk (500GB instead of 80GB).
I've partitioned the new disk.
When I copy partitions from the old disk to the new one
with "cp -a" (running under a Fedora Live CD)
I get a lot of messages of the form
  diff: a/bin/acroread: No such file or directory
  diff: b/bin/acroread: No such file or directory

All the messages concern symbolic links.
I see in "man cp" that  "cp -a" included
  "--no-dereference never follow symbolic links in SOURCE"

Does this mean cp is not an appropriate way to copy partitions?
I thought of using dd, but the partitions are not the same size,
and I was not sure if this would cause problems.

Any suggestions gratefully received.

Thanks for your and the many other suggestions.
I'm going to follow your advice and use rsync,
which seems most appropriate since the I have already copied the partitions.

I'm planning on saying "rsync -auvz" (which is my usual recipe).
If anyone can suggest better options I shall be glad to hear them.

I did actually do that, after changing the UUID settings in fstab.
But I was surprised to find that Fedora-20 Live CD (on a USB stick)
did not seem to do the trick, but the Netinstall CD did the job.

I'm not sure what environment the OP was using to do the copy (e.g.
rescue mode, live CD, etc.), but some things install relative links,
which should always work, while some install fully-specified links,
which won't when the FS is mounted under a different location.

For example, if you have /usr/bin/acroread as a symlink to
/opt/Adobe/Reader/9/bin/acroread, but then you boot a recue mode and
mount the root FS under /mnt/sysimage, the /usr/bin/acroread link will
be broken.

If instead you have something like /usr/bin/Mail linked to
../../bin/mailx, it will still work.

That may be all the OP is seeing, depending on the environment used.

please excuse omission, as i did fail to mention this is with
CentOS release 6.5 (Final).

i had same problem with with sl5.? when i stopped using it.

tho, it could be that it is fixed in fedora and not yet in rhel.

then again, being that your directories have no files and are
top of path, it copies.

and again, being that it has been awhile that i found this
problem, it may be just files, as my 'chemo brain' recalls,
it happened when saving web pages and then coping them elsewhere.
[to many web pages are written with oos] now, when i copy web
pages that have spaces in their names, i either omit space or
use '-' for space.

also, from habits of early unix days, i never create directory
or file names with spaces.

If you want to move the whole /home directory as is:
rsync -avxHSAX /home/ /new/home

-a includes -P, so copying symlinks is not his problem.  His problem
is that the links are broken, as reported by diff.

I think the Option "-P" will do it.

One issue that you may run into is that the
UUID of the disks will not be the 
same, so without modifying the boot files, the system will not work.

Generally, I just clone the old disk to the new disk using a livecd with G4L, 
which I am the maintaner of, or other ones like clonezilla or G4U. That will 
give you the same size partitions on the new disk, but you can then use other 
programs like gparted or LVM utilities to use the extra space.

I recently cloned an 80G disk to a 1T disk with no issues, and since the clone 
process uses dd to copy the raw data, all the links and other issues are not a 
problem.

"dd" is a much better command that "cp" for this.  See the following
for more info and a good background as to what is going on:

https://wiki.archlinux.org/index.php/Disk_Cloning

The sections on "Cloning a partition" and "Cloning an entire hard
disk" are the bits you want.  Also take a look at the bit about the
MBR - useful if you want a bootable drive after the cloning if you
didn't take care of it when you created the partitions on the new
drive.

Yes. And good chance you'll need to run dracut to rebuild all initramfs's; for
sure if it's being moved to new hardware. It might tolerate same hardware, different
drive and fs volume UUID, but I know that the initramfs contains references to the volume
UUID so you're better off rebuilding the initramfs's.

That is not true.  cp handles files with any characters just fine (just
tested on an old RHEL 4 system with coreutils-5.2.1).

I would gues you have run into shell quoting issues, but that's the
standard "fun" of using special characters in filenames and Unix shells.
You can't just say:

$ cp File With Spaces.txt /tmp

you have to:

$ cp "File With Space.txt" /tmp

Don't you have to correct UUIDs in /etc/fstab on the new disk?

Hi G, you are sure?

i do not know what version of 'cp' you have, but i can tell you that
"cp (GNU coreutils) 8.4" does not copy directories or files that have
a space in their name. which is why i use 'find|cpio' for disk and
directory path coping.

to insure that i have all directories and files, i open a terminal at
top of copy source and target paths and run 'ls -lR > 00-path'. then
i use kwrite to open files, move to bottom of files and compare the
line number to insure all has been copied.

I am planning a migration from a present F20 installation to a new 
system--that is, a new physical box on which I will do a completely 
fresh installation of F20 from the KDE spin. I am prepared to re-install 
all applications. All I want to do is move the contents of /home. What 
are the best commands for doing this?

"rsync -avxHSAX" will do it all.

I've done that quite often, and it's no problem.

1. Boot from an external medium, e.g. www.sysresccd.org
2. Mount both disks
3. Use "rsync -avxHSAX /source/ /target" to copy the partitions
4. Install grub2 on the new disk:
   - mount /dev/sdaX /mnt
   - grub2-install --root-directory=/mnt /dev/sda
   - grub2-mkconfig -o /mnt/boot/grub2./grub.cfg

Reboot, and you're done.

Anaconda LiveCD uses -pogAXtlHrDx

I'm pretty sure that's the same as -aAHXx

Realize with x that it expect to rsync each volume separately, so you don't do rsync
on / and expect that it will copy things correctly to /boot on a volume separate from /var
or /.

-a does it, but diff is complaining that the links are broken.  In my
case, /bin/acroread -> /opt/Adobe/Reader9/bin/acroread.

For copying the OS, you will also want -HAX to correctly copy
hard-linked files, access-control lists, and extended attributes.  For
disk-to-disk copies, drop -z (don't need to compress).  -u shouldn't be
needed (since you want an identical system, something newer on the
target shouldn't happen, and should probably be replaced if found).  If
the target has possibly been altered (or files have been deleted from
the source), add --delete.

I like adding -P (for --partial --progress); it gives more info during
sync and won't remove any partially-copied files (not usually an issue
for disk-to-disk, but useful for network transfers).

So, "rsync -aHAXvP --delete" would be my recommendation.

Also, unless you've disabled SELinux, you may need to relabel on the
first boot from the copy (not sure if rsync -X will set that correctly
or not; haven't checked in a while).

IMHO, the best choice for these kind of tasks is using bare metal recovery 
with tools like Mondorescue: http://www.mondorescue.org/

You can create with it a liveCD (or a USB bootable image) of the operating 
system filesystems, install the OS in this manner, then recover the user 
data (i.e. /home) using tools like rsync (even tar!) with the appropiate 
options.

Are you sure? I did the following:


backes@eule [~]: mkdir aaaaa
backes@eule [~]: cd aaaaa
backes@eule [~/aaaaa]: ln -s ~ l
backes@eule [~/aaaaa]: cd ..
backes@eule [~]: cp -rP aaaaa bbbbb/
backes@eule [~]: ls -l bbbbb
total 0
lrwxrwxrwx 1 backes backes 12 May 28 18:26 l -> /home/backes

(r is used for recursivity)

So "-P" will do it :-)

I see no way to tell cp to copy a symbolic
link as a symbolic link.

Use dd and resize2fs.
resize2fs defaults to the size of the partition.

If your using lvm, what I typically do is add both disks to the volume 
group, then you can use pvmove to move your lv's to the new pv.  The 
just vgreduce the old pv out of the vg. Then you can lvextend your lv's 
as you see fit from your new disk.

Of course, I /boot has to be out side of lvm, but can be copied 
manually. And you'll have to manually install the grub boot loader on 
the new disk as well.

There must be a zillion ways to do this (rsync, cpio, even cp) so I'll
throw in my personal favorite:

# cd /old
# tar --one-file-system -cf - . | (cd /new && tar xpf -)

I'd also have expected cp -a to work.
Sorry, I can't say what the problem with that is,
but my next try would be rsync.

I've used rsync to do this (you have to go through the gazillion
options to get all the appropriate ones though).

You'll also have to do something like boot from a live CD
in order to run grub-install (or grub2-install) to make the
new disk bootable.

find | cpio pipelines work well here, using cpio in 'pass' mode.  See 
the man page.
