NAME

       Pacemaker - Part of the Pacemaker cluster resource manager

SYNOPSIS

       crm_shadow (query|command) [modifiers]

DESCRIPTION

       crm_shadow - Perform configuration changes in a sandbox before updating the live cluster.

       Sets  up  an  environment  in which configuration tools (cibadmin, crm_resource, etc) work
       offline instead of against a live cluster, allowing changes to be previewed and tested for
       side-effects.
