there's another useful option of rsync: -x causes the synchronization to restrict the operation to a single filesystem. I.e. if there are other mounts under the source disk they will not be copied in case -x is added to the rsync command:Hello, 2014-02-05 Kruppt <krupptus@fastmail.fm>:On 2014-01-31, Kruppt <krupptus@fastmail.fm> wrote:On 2014-01-31, Fabrice Vaillant <fa.vaillant@gmail.com> wrote:Hi I'm using debian 7.3 on my laptop (Dell E5530) and it runs perfectly fine. I'm considering remplacing the hdd by a ssd. The thing is I'd rather not go through the hassle of setting up debian to suit my computer. The question I'm asking is, what would be the simplest way(if it is possible) to "clone" my existing installation onto the new ssd. Knowing that the root and the home are on two different partition of my hdd which are the only partition on my disk beside the swap. Howewer the ssd is smaller than the disk and the home partition will need to be resized. I also consider slightly increasing the root partition size as it is quitte full (77%) after running "apt-get clean". Since I am at it, I would also like to know if it is possible to remove the swap as it is bad for ssd life to write and rewrite, and I have plenty (8 giga) of ram. Cheers FabriceYes you can clone it easily with rsync. Create the partitions and filesystems on the new SSD, via gparted or fdisk, mke2fs or whatever. Then use rsync to clone the filesystems onto the new SDD partitions/filesystems. Lets say the original HDD is layed out like below as an example, and partitions, filesystems have been created, Boot up a LiveCD such as SystemRescueCD on a comp with both drives connected. Make mount points for partitions to be cloned and mount them all. HDD sda1 swap sda2 / sda3 /home SSD sdb2 swap sdb2 / sda3 /home >From Root Terminal run: rsync -av --delete /mnt/sda2/ /mnt/sdb2;rsync -av --delete /mnt/sda2//mnt/sdb2 Above line should read: rsync -av --delete /mnt/sda2/ /mnt/sdb2;rsync -av --delete /mnt/sda3/ /mnt/sdb3to clone the whole system you should not forget hardlinks (-H), and may be also ACL (-A) or extended attributes (-X) should be preserved. -a, --archive archive mode; equals -rlptgoD (no -H,-A,-X) When the cloned disk is updated several times, also option -u (=update only if needed) can be used. # rsync -avuHAX --delete /mnt/sda2/ /mnt/sdb2
# rsync -avuHAXx --delete /mnt/sda2/ /mnt/sdb2 E.g. to clone the root of the currently running system, omitting /proc etc.: # rsync -avuHAXx --delete / /mnt/yet_another_root_disk BR, Roland
This clones the two filesytems on the HDD to new SSD (since there is nothing on the new filesystem the --delete option is redundant so could be ignored) Then you would want to install Grub. Chroot into the / filesystem on SSD (sdb2 in this example) mount --bind /proc /mnt/sdb2/proc mount --bind /sys /mnt/sdb2/sys mount --bind /run /mnt/sdb2/run mount --bind /dev /mnt/sdb2/dev mount --bind /dev/pts /mnt/sdb2/dev/pts chroot /mnt/sdb2 /bin/bash grub-install --root-directory=/mnt/sdb2 /dev/sdb grub-mkconfig -o /boot/grub/grub.cfg update-initramfs -uk $(uname -r) exit chroot Then you will need to edit your fstab file, to reflect changes if any, especially if using UUID's. (Run blkid -c /dev/null, the output will show the UUID's, then edit fstab to reflect new UUID's)-- To UNSUBSCRIBE, email to debian-user-REQUEST@lists.debian.org with a subject of "unsubscribe".
