If anyone could offer any advice it would be much appreciated.



I am running Ubuntu Server 18.04.2 LTS server with 9 x 3TB WD Red hard drives in a RAID 5 configuration, using MDADM.



Is there any reason why I am seeing a difference in total RAID size capacity? I have attached some screen grabs with hopefully the correct information. If im missing anything please let me know.



Many Thanks.....
