drives and stuff

17 Mar 2011

so i installed 4 new harddrives, 2 1tb drives and 2 2tb drives. not really too sure what i want to do with them. so i put them in a raid:

 $  sudo mdadm --create /dev/md0 --level=1 --raid-devices=2 --metadata=0.90 /dev/sdc1 /dev/sdd1
 $  sudo mdadm --create /dev/md1 --level=1 --raid-devices=2 --metadata=0.90 /dev/sde1 /dev/sdf1

then i thought, "man, it'd be cool if there were encrypted." so i did that, too. pretty much following any other blog of instructions, i made a couple keys for each drive:

  $  dd if=/dev/urandom of=/mnt/usb/luks-2tb-raid bs=512 count=4
  $  dd if=/dev/urandom of=/mnt/usb/luks-1tb-raid bs=512 count=4

and then i set up luks:

  #  cryptsetup -c aes-xts-plain -s 512 -v luksFormat /dev/md0 /mnt/usb/luks-1tb-raid 
  #  cryptsetup -c aes-xts-plain -s 512 -v luksFormat /dev/md1 /mnt/usb/luks-2tb-raid 

then i opened the luks partitions and did the lvm stuff:

  #  cryptsetup luksOpen /dev/md0 crypt1 --key-file /mnt/usb/luks-1tb-raid 
  #  cryptsetup luksOpen /dev/md1 crypt2 --key-file /mnt/usb/luks-2tb-raid 
  #  pvcreate /dev/mapper/crypt1
  #  pvcreate /dev/mapper/crypt2
  #  vgcreate bitshit /dev/mapper/crypt1 /dev/mapper/crypt2
  #  lvcreate -L 1T -n torrents bitshit
  #  lvcreate -L 1T -n homeshit  bitshit
