+# Setup RAID

+### List all devices
+
+````
+lsblk
+````
+
+### Create new partition
+
+For each drive you'll need to type `fdisk /dev/sdx` replace the `x` with the letter of the drive. and youll want to use option `d` to delete a partition and `n` to make a new partition, just go ahead and use the smaller value for start and biggest value for last sector since im sure you want to utilize the whole drive, then optionp to print the partion table then option `w` to finalize the whole thing. repeat for all the drives involved.
