In this post, I will describe how to move to a new harddrive, either server or desktop (linux).
This topic is outside the "hosting" topic, but may be useful for you.
Suppose that you have one old drive, (/dev/sda), Luks encrypted.
one new drive, bigger (/dev/sdb)
New drive has no partitions (or may have also...)
This command copies all of old drive onto new one, with a kind of progress indicator..
pv -n /dev/sda | dd of=/dev/sdb bs=128M conv=notrunc,noerror
this takes long time, depending on your old drive size.
