The question for formated

Hello, I have the question?
do I format 4x 4TB in btrfs or ext4? which ?
thank you

Hello @rodrigue7973be,

You don’t need to format the disks, Rockstor will take care of that when you add them to a new/existing Storage Pool.

4x To emptied erased? no ?

Hey @rodrigue7973be,

Yes, you’d want them to be empty. If they aren’t, you can erase them from within the Rockstor GUI in Storage > Disks.
