Optimized resynchronization in Solaris Volume Manager for Sun Cluster functions identically to optimized resynchronization in Solaris Volume Manager. However, in a multi-owner disk set, a RAID-1 volume with the resynchronization option set to optimized resynchronization always has a mirror owner. The following output from the metastat -s diskset-name command shows the resynchronization option set to optimizedresync (for optimized resynchronization).
# metastat -s red red/d24: Mirror Submirror 0: red/d20 State: Okay Submirror 1: red/d21 State: Okay Pass: 1 Read option: roundrobin (default) Write option: parallel (default) Resync option: optimizedresync Owner: nodeone Size: 825930 blocks (403 MB)
