System Administration Commands - Part 3

metareplace

- enable or replace components of submirrors or RAID5 metadevices

Synopsis

/usr/sbin/metareplace -h
/usr/sbin/metareplace [-s setname] -e mirror component
/usr/sbin/metareplace [-s setname] mirror component-old component-new
/usr/sbin/metareplace [-s setname] -e RAID component
/usr/sbin/metareplace [-s setname] [-f] RAID component-old component-new

Description

The metareplace command is used to enable or replace components (slices) within a submirror or a RAID5 metadevice.

When you replace a component, the metareplace command automatically starts resyncing the new component with the rest of the metadevice. When the resync completes, the replaced component becomes readable and writable. If the failed component has been hot spare replaced, the hot spare is placed in the available state and made available for other hot spare replacements.

Note that the new component must be large enough to replace the old component.

A component may be in one of several states. The Last Erred and the Maintenance states require action. Always replace components in the Maintenance state first, followed by a resync and validation of data. After components requiring maintenance are fixed, validated, and resynced, components in the Last Erred state should be replaced. To avoid data loss, it is always best to back up all data before replacing Last Erred devices.

Options

Root privileges are required for all of the following options except -h.

-e

Transitions the state of component to the available state and resyncs the failed component. If the failed component has been hot spare replaced, the hot spare is placed in the available state and made available for other hot spare replacements. This command is useful when a component fails due to human error (for example, accidentally turning off a disk), or because the component was physically replaced. In this case, the replacement component must be partitioned to match the disk being replaced before running the metareplace command.

-f

Forces the replacement of an errored component of a metadevice in which multiple components are in error. The component determined by the metastat display to be in the ``Maintenance'' state must be replaced first. This option may cause data to be fabricated since multiple components are in error.

-h

Display help message.

-s setname

Specifies the name of the diskset on which metareplace will work. Using the -s option will cause the command to perform its administrative function within the specified diskset. Without this option, the command will perform its function on local metadevices.

mirror

The metadevice name of the mirror.

component

The logical name for the physical slice (partition) on a disk drive, such as /dev/dsk/c0t0d0s2.

component-old

The physical slice that is being replaced.

component-new

The physical slice that is replacing component-old.

RAID

The metadevice name of the RAID5 device.

Examples

Example 1 Recovering from Error Condition in RAID5 Metadevice

This example shows how to recover when a single component in a RAID5 metadevice is errored.

# metareplace d10 c3t0d0s2 c5t0d0s2

In this example, a RAID5 metadevice d10 has an errored component, c3t0d0s2, replaced by a new component, c5t0d0s2.

Example 2 Use of -e After Physical Disk Replacement

This example shows the use of the -e option after a physical disk in a submirror (a submirror of mirror mymirror1, in this case) has been replaced.

# metareplace -e mymirror1 c1t4d0s2

Note: The replacement disk must be partitioned to match the disk it is replacing before running the metareplace command.

Exit Status

The following exit values are returned:

0

Successful completion.

>0

An error occurred.
