Option 2: Converting a Volume with Existing Data to an EVFS Volume
(Inline Encryption)
This section describes how to convert existing data on a volume into an EVFS Volume. This
section addresses the following topics:
• “Step 1: Preparing the File System and Data” (page 66)
• “Step 2: Performing Inline Encryption” (page 67)
• “Step 3: Verifying the Configuration” (page 69)
• “Step 4: (Optional) Configuring the Autostart Feature” (page 72)
• “Step 5: Backing Up Your Configuration” (page 74)
Before using this procedure, you must complete the tasks in Chapter 3 (page 35).
IMPORTANT: To use inline encryption, 3 MB of spare disk space are required at the end of the
volume, and the minimum volume size must be 4 MB. If the entire volume is used, extend the
volume using lvextend for LVM, or vxassist for VXVM.
