Is there a list of recommended VDEV types for 2, 3, 4 and 5 hard drives? Can one change a VDEV once it has been created?
Thanks
The best layout depends on the use case:
Block storage (small records) → mirrors
Bulk storage → raidz#
You cannot change raidz level, or change from mirror to raidz, after creation so get it right from the start.
