How to Add Mediator Hosts
Perform this procedure if your configuration requires mediators.
Become superuser on the node that currently masters the diskset to which you intend to add mediator hosts.
Run the metaset(1M) command to add each node with connectivity to the diskset as a mediator host for that diskset.
# metaset -s setname -a -m mediator-host-list
-s setname Specifies the diskset name
-a Adds to the diskset
-m mediator-host-list Specifies the name of the node to add as a mediator host for the diskset
See the mediator(7D) man page for details about mediator-specific options to the metaset command.
Check the status of mediator data.
Example--Adding Mediator Hosts
The following example adds the nodes phys-schost-1 and phys-schost-2 as mediator hosts for the diskset dg-schost-1. Both commands are run from the node phys-schost-1.
# metaset -s dg-schost-1 -a -m phys-schost-1 # metaset -s dg-schost-1 -a -m phys-schost-2 |
How to Check the Status of Mediator Data
Add mediator hosts as described in How to Add Mediator Hosts.
Run the medstat command.
# medstat -s setname
-s setname Specifies the diskset name
See the medstat(1M) man page for more information.
Is Bad the value in the Status field?
If yes, go to How to Fix Bad Mediator Data to repair the affected mediator host.
If no, go to How to Add Cluster File Systems to create a cluster file system.
How to Fix Bad Mediator Data
Perform this procedure to repair bad mediator data.
Identify the mediator host(s) with bad mediator data as described in the procedure How to Check the Status of Mediator Data.
Become superuser on the node that owns the affected diskset.
Remove the mediator host(s) with bad mediator data from all affected disksets.
# metaset -s setname -d -m mediator-host-list
-s setname Specifies the diskset name
-d Deletes from the diskset
-m mediator-host-list Specifies the name of the node to remove as a mediator host for the diskset
Restore the mediator host.
# metaset -s setname -a -m mediator-host-list
-a Adds to the diskset
-m mediator-host-list Specifies the name of the node to add as a mediator host for the diskset
See the mediator(7D) man page for details about mediator-specific options to the metaset command.
Create cluster file systems.
