 Posted: Tue Nov 23, 2004 1:32 am Post subject: MIGRAZIONE Trasferire l'installazione su altro disco[SOLVED] |
 |
|
Sto sostituendo l'hard-disk che avevo con uno più capiente.
Come posso fare a trasferire l'istallazione da una parte all'altra?
con le espressioni regolari?
Qualcuno ha qualche esperienza/link?
Grazie

Il metodo più pratico che mi viene è
partire con il live cd
montare il disco di partenza
montare il disco di destinazione
fare copia con cp -a partenza destinazione
Poi mettere in ordine il booter (grub o lilo che sia), ed il file /etc/fstab.
Dovrebbe bastare questo!
ciao

Magari mettendoci anche un -p per presevare i permessi

Dal man:
| Code: | -a, --archive
Preserve as much as possible of the structure and attributes of the original files in the copy (but do not pre-
serve directory structure). Equivalent to -dpPR. |

questo è uno script che avevo trovato in giro per il forum qualche tempo fa...
ti darei il link esatto, come giusto... ma non lo trovo
quindi ti passo direttamente lo script, che famo prima:

# like /dir1/dir2, never something like /dir or /dir1/dir2/dir3...
# CLONE_DIR either have to be defined in /etc/fstab, or mounted...
# BIND_DIR is a directory to mount - bind your root partition (it is needed for your
# gentoo system which uses devfs - otherwise /dev will not be correctly copied...
# If you do not want to change the fstab file for your cloned partition, set
# FSTAB_FLAG to 0...

questo invece è il copia-incolla del post:
Dear Gentooers,
Often times there are upgrades or changes which can potentially render you nicely configured system unsusable. If
this disaster happened, it is a very good feeling to have the EXACT copy of your original root partition backed up
and ready to use! I wrote a bash script which will clone your gentoo partition on another partition, so you are safe
to do anything advetureous...
Why is the script? Isn't "cp -a / /mnt/clone" would be enough? Unfortunately, this would require to unmount separate
partitions, like /home, and could cause problems with /dev partition which gentoo uses. Certain special files would
also be left out. So, after a reading a long discussion on gentoo user list, I chosen the possibly safest solution
(at least what I tried) and wrote a scrip around it to make it easy to use.
I have two (same sized) partitions for gentoo root. I also have /home on a separate partiton and I have one separate
partition containing /usr/local (symlinked), /opt (symlinked), /var/tmp/portage (PORTAGE_TMPDIR set in make.conf),
/usr/portage/distfiles (DISTDIR set in make.conf). Before I do something dangerous, I run the script to duplicate my
root partition, and with this setup I leave out some bulky stuff (copying your distfiles) which normally is not
changed that much.
The script has a "pretend mode", so you can see what will happen without any danger...
Here is the help taken from the script (you can also display it with "gent-clone -h")
"############## gent-clone help #####################"
This script will clone your gentoo root partition to "
another partition. Usage:"
gent-clone mode [destination mount point]"
where mode = "-c" Clones current root partition to a destination partition'
"-p" Prentend cloning; useful to see what would happen without any changes'
"-h" Prints this message...'
'Destination mount point should be given as /dir1/dir2 or /dir format, if it is not supplied, then the program uses
internal defaults (can be changed at the beginning of the script). A partition should be attached to the destination
directory or the mount point listed in /etc/fstab before using the script! Normally, the /etc/fstab file on your
root partition will be edited by the script: A new adjusted /etc/fstab is created and copied over - this contains
your destination partition mounted as root. If you do not want this behavior, set the FSTAB_FLAG variable from 1 to
0 by editing the first part of this script.
Examples:
gent-clone -c /mnt/clone
-->clone you root partititon to the partition mounted on /mnt/clone '
gent-clone -c
-->clone your current root partition to your predefinied'
partition (set this up by editing the first part of the script)
gent-clone -p
--> Pretend mode: Prints out what will happen when you issue a -c argument'
I call this file as gent-clone. Copy it to an empty file and save it.
I hope someone finds this helpful, I certainly used it regularly...
Cheers: Viktor

ho 'trapiantato' con successo il mio vecchio hd su un nuovo 40G, ed ho seguito lo stesso metodo descritto da comio:
| Code: | # mount /dev/hdd2 /mnt/vecchio
# mount /dev/hdb5 /mnt/nuovo
# cp -a /mnt/vecchio/* /mnt/nuovo |
did the trick ;)
nel mio caso ho anche dovuto apportare le (ovvie) modifiche a:
/boot/grub/grub.conf
/etc/fstab
e tutto ha funzionato senza problemi :)

Provo il metodo di mark!
Ma intanto mi studio lo script(a la faccia dello zio BILL ...e scusate se è poco) che sicuramente è una cosa seria!
