| + | ====== Stop services ====== | ||
| + | You should stop this service before to proceed the copy, else there is a risk your mysql database to be corrupted. | ||
| + | <code> | ||
| + | root@yunohost:/media# service nginx stop | ||
| + | root@yunohost:/media# service mysql stop | ||
| + | root@yunohost:/media# service postfix stop | ||
| + | root@yunohost:/media# service rmilter stop | ||
| + | root@yunohost:/media# service dovecot stop | ||
| </code> | </code> | ||
| ====== Copying ====== | ====== Copying ====== | ||
| + | |||
| + | Now you have to copy everything from the SD card to the disk. ([[https://wiki.archlinux.org/index.php/Full_system_backup_with_rsync#With_a_single_command|source]]) | ||
| + | |||
| + | <code> | ||
| + | mkdir -p /tmp/sata | ||
| + | mount /dev/sda1 /tmp/sata | ||
| + | rsync -aAXv --exclude={"/dev/*","/proc/*","/sys/*","/tmp/*","/run/*","/mnt/*","/media/*","/lost+found"} / /tmp/sata | ||
| + | </code> | ||
| + | |||
| + | |||
| + | Now, your SATA drive contains a complete copy of your system, but one important thing is missing: your kernel is in ''/tmp/sata/boot'', but this folder should actually mount /dev/mmcblk0p1, which already contains the system you are currently running. | ||
| + | |||
| + | <code> | ||
| + | cd /tmp/sata | ||
| + | mv boot boot.old | ||
| + | mkdir boot | ||
| + | mount /dev/mmcblk0p1 boot | ||
| + | rsync -av boot.old/ boot/ | ||
| + | </code> | ||
| + | |||
| + | Now, the ''/boot'' of the new system exists alongside the ''/'' of the old system. | ||
| ====== Rebooting ====== | ====== Rebooting ====== | ||
| - | ====== Cleaning ====== | + | Now, cross your fingers and reboot your cube. Or the other way around if it's too hard to type. |
| + | |||
| + | Can you log into your cube ? Congratulations ! It worked ! | ||
| + | |||
| + | ====== Cleaning up ====== | ||
| + | |||
| + | Now, your old system is cluttering the ''/boot'' folder. To clean it up, you can remove everything in this folder, and reuse the ''/boot.old'' copy we did earlier. | ||
| + | |||
| + | <code> | ||
| + | cd /boot | ||
| + | rm -rf * # /!\ proceed carefully /!\ | ||
| + | mv /boot.old/* . | ||
| + | rmdir /boot.old | ||
| + | </code> | ||
| + | Everything should be fine now ! | ||
| + | An alternative approach: remove everything from ''/boot'', then run ''update-initramfs -u''. This will regenerate everything necessary inside ''/boot''. | ||
