Encrypted Volume and File System v1.1 Administrator's Guide

Examples

This section contains configuration examples for “Option 1” (page 75) and “Option 2” (page 76).

Option 1

Step 1a: Create an EVFS volume. If you are using LVM or VxVM, create a new LVM or VxVM

volume to use as the underlying volume. If you reuse an existing LVM or VxVM volume as the

underlying volume, you will lose all existing data. You can skip this step if you are using whole

disk access.

# lvcreate -L 64 -n lvol5 /dev/vg01

Step 1b: Map the new LVM or VxVM volume or physical volume to an EVFS volume.

# evfsadm map /dev/vg01/lvol5

Step 1c: Create the EMD on the new EVFS volume. The root user (the owner of the key named

rootkey1) will be the volume owner. evfsvol prompts for the passphrase to the owner's

private key.

# evfsvol create -k rootkey1 /dev/evfs/vg01/lvol5

Step 1d: Optional – Add a recovery user key. evfsvol prompts for the passphrase to the owner's

private key.

# evfsvol add -r /dev/evfs/vg01/lvol5

Step 1e: Enable the EVFS volume. evfsvol prompts for the passphrase for your key named

rootkey1.

# evfsvol enable -k rootkey1 /dev/evfs/vg01/lvol5

Step 2a: Create a new file system on the character/raw EVFS volume.

# newfs -F vxfs /dev/evfs/vg01/rlvol5

Step 2b: Verify the file system.

# fsck /dev/evfs/vg01/rlvol5

Step 2c: Create the directory for the new mount point.

# mkdir /opt/my_secure_dir

Step 2d: Mount the new file system.

# mount -F vxfs /dev/evfs/vg01/lvol5 /opt/my_secure_dir

Step 2e: Optional—Add an entry to /etc/fstab. In this example, the administrator used the

echo command, but you can also use an editor to do this

# echo "/dev/evfs/vg01/lvol5 /opt/my_secure_dir vxfs defaults 0 2" >>

/etc/fstab

Step 3: Verify the EVFS configuration.

# evfsadm stat –a

# evfsvol display /dev/evfs/vg01/lvol5

Step 4: Migrate any existing data.

To migrate an existing directory of data to the new EVFS volume, follow these steps:

Step 4b: Stop all applications accessing the existing data.

# fuser –cu /opt/my_data

# fuser –cku /opt/my_data

Step 4d: Copy the existing data to the new EVFS directory.

# cp –R /opt/my_data /opt/my_secure_dir

Clean up the old data and create a symbolic link to the EVFS data.
