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:

	   o   next	-- display the next host

	   o   last	-- display the last host

	   o   dump	-- display all hosts

       fe <...>  -- FileEntry menu
	   o   hdr	-- display the callback_state_header struct

	   o   first	-- display the first FE

	   o   prev	-- display the previous FE

	   o   dump	-- display all FEs

	   o   timeout	-- display the timeout queue heads

	   o   hash	-- display the file entry hash buckets

	   o   find by index id -- find an fe by its array index

	   o   find by fid (vol,vnode,unique) -- find an fe by its AFSFid

       cb <...>  -- CallBack menu
	   o   hdr	-- display the callback_state_entry_header struct

	   o   first	-- display the first CB

	   o   prev	-- display the previous CB

	   o   last	-- display the last CB

	   o   dump	-- display all CBs

       hexdump [offset [len]]  -- hex dump raw data
       quit	-- quit current menu
       exit	-- exit debugger
       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.

	   [-h]

DESCRIPTION

       The fssync-debug callback command breaks callbacks for a volume.

OPTIONS

       -volumeid <volume ID>
	   Specifies the numeric volume ID. Volume names are not permitted.

       -partition <exact partition name>
	   Specifies the exact partition name (e.g. /vicepa). Abbreviations are not permitted.

       -reason <sync protocol reason code>
	   Specifies numeric sync protocol reason code.  Available codes are listed in OpenAFS source file src/vol/fssync_inline.h. For
	   SYNC_REASON_NONE, use -reason 0.

       -programtype <program type code>
	   Specifies program type code. Permitted values are fileServer, volumeUtility, salvager, salvageServer, volumeServer and volumeSalvager.

PRIVILEGE REQUIRED

       The issuer must have write access to the file server.  Usually, this means that the issuer must be the local superuser "root" on the file
       server machine.
