RAID edits

• Enter the system setup menu at boot time, then you also have to press additional keys to get to the RAID screen
• create a new virtual disk and assign the new disks, then initialize the VD

Mounting the new VD

• find the disk with fdisk -l | grep '^Disk'
• create a partition table
  • fdisk /dev/sdb
  • p to list partition table if any
  • n to create a new partition
  • w to write the new partition
• format the new partition with mkfs.ext4 /dev/sdb1
• create an access folder, maybe at //mnt/backup
• run the mount mount /dev/sdb1 /mnt/backup
• edit fstab by adding
  • using device name

  //dev/sdb1  /mnt/backup ext4    defaults    1   2
  

  • using UUID (do sudo blkid to get the UUID)

  UUID="86e81045-a0dc-4881-8ddb-5ef25834ea5a" /datadrive  xfs     defaults,nofail 1       2
