 |
|
hi there,
i plan to use a new hdd for my root,boot and swap partition, currently 160gb with ext3 (boot ext2) , the new one would be a 500gb with ext4 (boot ext2)
so is there a simple (and perhaps fast) way of copying the contents of the old one to the new, like cp -r / /path/to/newhdd ?
are there any important things to observe, except correct fstab and grub.conf
or have i to rebuild my hole system ?
thanks for any help
greetings
michael

i think you need | Code: | | cp -a old_path new_path |

as long as you stick to the same system, only fstab and grub can cause problems...
for consistency reasons, I would suggest to use a liveCD for the move.
- boot up the live cd
- partiton and format the new hdd
- mount both hdds, (i.e new one to /mnt/gentoo, the old one to /mnt/oldsystem; don't forget boot)
- copy your system (cp -av /mnt/oldsystem/* /mnt/gentoo/)
- mount proc and dev to the new system
- chroot, and install grub (don't forget to adjust grub.conf)
- fix fstab (i.e sda -> sdb)
cheers

No, no and no. All of above solutions are too complicated! Fast, easy and perfectly reliable is only mine 
Rsync is used here to synchronize two directories, x option says it should stay on one filesystem, avH stands for all verbose, H for preserving hard links, progress is just for progress.
| Code: | | rsync -avHx --progress / /mnt/root/ |
Then adjust grub.conf and fstab, install grub on your new drive (using manual) or adjust your existing grub (if you want to boot from the old disk).
Oh, and I've forgot to mention that you need to be on runlevel 1 or instead you agree to lost data written after your last rsync.
All done  |

thanks for the tipps,
i tried the last one,the rsync-thing, with my home/- hdd.
connecting the new hdd directly to the sata controller. about 1 or 1 1/2 half hour for ~400GB of data.
the great thing was that i not really felt whats going on.
so i could continue work and later simply changed the hdd ...
and forgot to change the fstab filesystem line to ext4 ^^
for the root partition i am going to wait, because i've not really time to do this at the moment
thanks |
