raid 1 using mdadm and llvm setup on debian

I'm assuming following disks are going be part of the new raid1:

• /dev/sdb
• /dev/sdc

1. Create software raid 1:

   sudo mdadm --zero-superblock /dev/sdb /dev/sdc
   sudo mdadm --create /dev/md0 --level=1 --raid-devices=2 /dev/sdb /dev/sdc
   sudo bash -c "mdadm --detail --scan /dev/md0 >> /etc/mdadm/mdadm.conf"
   

2. setup lvm:

   # create lvm physical volume
   sudo pvcreate /dev/md0
   
   # create lvm volume group
   sudo vgcreate vgSix /dev/md0
   
   # create lvm logical volume
   sudo lvcreate -n six --size 5T vgSix
   
   # make fs
   sudo mkfd -t ext4 /dev/vgSix/six
   
   # label
   sudo e2label /dev/vgSix/six six
