How to (try to) recover data from failed RAID0 array

For experimental reasons I was running a RAID0 array (the speed!) off of two Sandisk Cruiser Mini USB sticks connected to a Raspberry PI.

As expected, due to wear and tear one of the flash memories eventually failed causing the array to go read-only and crash everything that was writing to it, including the array activation.

Migrating existing RAID1 volumes to bigger drives

Every once in a while hardware needs to be replaced. Sometimes boards, sometimes CPUs and sometimes drives. Drives are the ones most difficult to replace as they hold all that precious data one does not want to lose.

I personally hate reinstalling stuff; so I try as much as possible to “migrate” my data around. In this tutorial I’ll be replacing two drives under a RAID1 array with two newer bigger drives (and resize the array accordingly).
