I have a WD Thunderbolt two disk enclosure. Currently it’s set up as a two disk Raid 0 stripe using Disk Utility.
For additional data protection, I’d like to buy another two drives and mirror the existing Raid 0 stripe without losing or Migrating any data from the existing Raid 0 stripe. i.e upgrade to RAID 10.
I’m running El Capitan, 10.11.3
Is this possible to change from a two disk stripe to a 4 disk mirror without losing/migrating data off the RAID’ed volume?
Does anyone have a procedure to do this?
