[svlug] How to move the Linux OS ionstalled on two small HDDs to single large HDD

[Sargun Dhillon]

You have an alternate option if you don't feel like rebooting so much:
1. Plug in the second drive
2. Setup the second drive with LVM/RAID/Filesystems
3. Setup your boot loader and kernel
4. mount your drive RO like this: "mount -f -ro,remount /"
5. mount your new drive on a temporary mount point
6. copy it to your backup drive like this: "rsync --exclude=/proc
--exclude=/mnt/new -av / /mnt/new/"
7. Rinse and repeat steps 4-6 for each partition you have.
8. Reboot
