B.2.10 Mirroring the root (/) File System

You can mirror the root (/) file system to prevent the cluster node itself from going down due to a system disk failure. Refer to Chapter 2, Planning the Configuration, for more information.

The high-level steps to mirror the root (/) file system are:

• Using the metainit(1M) -f command to put the root slice in a single slice (one-way) concatenation (submirror1)

• Creating a second concatenation (submirror2)

• Using the metainit(1M) command to create a one-way mirror with submirror1

• Running the metaroot(1M) command

• Running the lockfs(1M) command

• Rebooting

• Using the metattach(1M) command to attach submirror2

• Recording the alternate boot path

For more information, refer to the metainit(1M), metaroot(1M), and metattach(1M) man pages and to the Solstice DiskSuite documentation.
