Veritas Volume Manager supports the use of the following types of logs and maps with volumes:
See "FastResync" on page 68.
These maps are supported either in memory (Non-Persistent FastResync), or on disk as part of a DCO volume (Persistent FastResync). Two types of DCO volume are supported:
See "Version 0 DCO volume layout" on page 71.
See "Creating a volume with a version 0 DCO volume" on page 260.
See "Version 20 DCO volume layout" on page 71.
See "Creating a volume with a version 20 DCO volume" on page 261.
See "Enabling FastResync on a volume" on page 302.
See "Dirty region logging" on page 61.
These logs are supported either as DRL log plexes, or as part of a version 20 DCO volume. Refer to the following sections for information on creating a volume on which DRL is enabled:
See "Creating a volume with dirty region logging enabled" on page 262.
See "RAID-5 logging" on page 52.
These logs are configured as plexes on disks other than those that are used for the columns of the RAID-5 volume.
