STATE_ANALYZER(8)	     AFS Command Reference	     STATE_ANALYZER(8)

NAME
       state_analyzer - Explores and queries the fileserver state database
       interactively

SYNOPSIS
       state_analyzer [state dump file | -h]

DESCRIPTION
       The demand-attach file server makes host / callback information
       persistent. On shutdown, the state is saved to database fsstate.dat(5).
       On startup, the state is read, verified and restored.  This allows for
       file server shutdowns or restarts without breaking all callbacks (an
       operation that could otherwise take a long time).

       state_analyzer interactively explores and queries the saved state
       database, fsstate.dat(5).

       This command is only supported on the demand-attach file server.	 It
       operates at an extremely low-level and hence requires detailed
       knowledge of the OpenAFS architecture and code.

COMMANDS
       state_analyzer supports the following interactive commands:

       help	-- help message

PRIVILEGE REQUIRED
       The issuer must have read access to the file server state database,
       fsstate.dat.  Usually, this means that the issuer must be the local
       superuser "root" on the file server machine.
