Example of RAID-1 Volume Disk Layout

The following figure shows a RAID-1 volume that duplicates the root file system (/) over two physical disks. State database replicas (metadbs) are placed on both disks.

Figure 12–2 RAID-1 Volume Disk Layout

Figure 12–2 shows a system with the following configuration.

• The root file system (/) on hdisk0 is included in the single-slice concatenation that is named d31.

• A single-slice concatenation that is named d32 is created on the hard disk that is named hdisk1.

• The mirror that is named d30 consists of the submirrors that are named d31 and d32.

• The mirror duplicates the data in the root file system on both submirrors.

• State database replicas are created on slices both hdisk0 and hdisk1.
