Problem

How can I change a standard file system to a large, file-enabled file system without down time or impact on the system?

Solution

Complete the following steps.
  1. Create the large file-enabled file system. Enter: 
       smitty jfs
  2. Change the type of the large file-enabled file system logical volume. Enter: 
       chlv -t copy [LVname]
  3. Copy the contents to an existing logical volume. Enter: 
       cplv -e [DestinationLogicalVolume] [SourceLogicalVolume]
  4. Change the type of the large file-enable file system logical volume once more. Enter: 
       chlv -t jfs LVname
  5. Run a file system check on the large file-enabled file system. Enter: 
       fsck -y [FileSystem]
  6. Mount the large file-enabled file system. Enter: 
       mount [FileSystem]
