FDISK

create partitions

RAID

create raid1/mirror device

# mdadm --create /dev/md7 --level=1 --raid-devices=2 /dev/sdg1 /dev/sdh1

for non bootable partition use v1.2

# mdadm --create /dev/md2 --metadata=1.2 --level=1 --raid-devices=2 /dev/sda5 /dev/sdb5

for bootable partition use v0.90

# mdadm --create /dev/md0 --metadata=0.90 --level=1 --raid-devices=2 /dev/sda1 /dev/sdb1

install grub in the master boot sector on both disks

# grub-install --force --no-floppy --root-directory=/mnt/target/ /dev/sda

# grub-install --force --no-floppy --root-directory=/mnt/target/ /dev/sdb

chroot as described and install a device map followed by update initramfs and grub

# update-initramfs -u -k `uname -r`

# update-grub

now system should be bootable from the raid disk

CRYPTSETUP

WARNING! The following command will remove all data on the partition that you are encrypting. You WILL lose all your information! So make sure you backup your data to an external source such as NAS or hard disk before typing any one of the following command.

In this example, I'm going to encrpt /dev/sdb7. Type the following command:

 # cryptsetup -y -v luksFormat /dev/sdb7

Open the crypted device

 # cryptsetup luksOpen /dev/sdb7 backup

Check the dm device

 # ls -l /dev/mapper/backup

or use following command

 # cryptsetup -v status backup

You can dump LUKS headers using the following command:

 # cryptsetup luksDump /dev/sdb7

Close a dm device after unmounting it

 # cryptsetup luksClose backup

LVM setup

Create physical volumes

 # pvcreate /dev/mapper/backup

Create a volume group

 # vgcreate G750lvm /dev/mapper/backup

After rebooting the system or running vgchange -an, you will not be able to access your VGs and LVs. To reactivate the volume group, run:

 # vgchange -a y G750lvm

Creating a logical volume

 # lvcreate -L50G -nroot G750lvm

 # lvcreate -L150G -nhome G750lvm

 # lvcreate -L200G -ncustom G750lvm

 # lvcreate -L150G -ndata G750lvm

 # lvcreate -L2G -nswap1 G750lvm

 # lvcreate -L2G -nswap2 G750lvm

Format the volumes

 # mkfs.ext3 /dev/mapper/G750lvm-root

 # mkfs.ext3 /dev/mapper/G750lvm-home

 # mkfs.ext3 /dev/mapper/G750lvm-custom

 # mkfs.ext3 /dev/mapper/G750lvm-data

 # mkswap /dev/mapper/G750lvm-swap1

 # mkswap /dev/mapper/G750lvm-swap2

copy data

 cd /mnt
 test -d target || mkdir target
 test -d source || mkdir source

 # mount ...(source) /mnt/source
 # mount /dev/mapper/G750lvm-root /mnt/target

 # tar cf - . | (cd /mnt/target/; tar xvf -)

umount and done

remove logical volume

umount the partition

close the volume

# lvchange -an /dev/vgcrypt/software

remove the volume

# lvremove /dev/vgcrypt/software
