       fsvmap - map volumes of VxFS file systems to files


       /opt/VRTS/bin/fsvmap    [   -mdv	  ]   [	  -c   checkpoint   |	-C   ]
       mount_point_or_vset [ volume ... ]

       The fsvmap command was introduced to  verify  Dynamic  Storage  Tiering
       allocation policies.

       The  fsvmap  command  maps  one	or more volumes to the files that have
       extents on those volumes.  By default, the output  is  limited  to  the
       default fileset.

       The  fsvmap command can report information on disabled volumes, as long
       as those volumes contain no metadata.  That is,	the  volumes  must  be
       dataonly.  See the fsvoladm(1m) manual page for information on dataonly
       volumes.	 The information on disabled volumes can be used to  determine
       which  files are or would be affected by the loss of a dataonly volume,
       both before and after the volume is lost.

       The fsvmap command only operates on VxFS multi-volume file systems.

       The fsvmap command considers extents for any extended attribute	inodes
       to be associated with the file that owns those attributes.

       Unprintable  characters in file names are translated into a sequence of
       printable characters so that each file is guaranteed to be displayed on
       a  single  line.	 The sequence is //0xXX, where XX is a hex sequence of
       the character's ASCII value.  Since // is not a	valid  sequence	 in  a
       filename,  the  format  is  unambiguous.	 For example, in the following

	Data	UNNAMED	     /file with	 embedded//0x0anewline	//0x0a	repre‐
       sents an embedded newline character.

       Use  the fsmap command to report extent information for files on a VxFS
       file system.  The functionality of fsmap is the reverse of fsvmap.

       The fsvmap command does not print any information for empty files.

Cluster File System Issues
       No cluster issues; command operates the same on cluster file systems.

       -C	 Displays output for all Storage Checkpoints as	 well  as  the
		 default fileset.

       -c checkpoint
		 Limits	 the  output  to files in the specified Storage Check‐

       -d	 Disables the translation  of  unprintable  characters.	  Each
		 filename  is  printed	without	 being translated, and is both
		 prefixed and suffixed by // to allow detection	 of  when  the
		 filename  begins  and	ends.	For example, a filename with a
		 newline character displays as follows:
		 Data	 UNNAMED      ///file with embedded

       -m	 Reports metadata for each file.

       -v	 Verbose output.

		 Specifies the mount point of a file system or a file system's
		 volume set device.

       volume	 Limits	 the  output to files on the specified volumes.	 If no
		 volumes are specified, fsvmap	reports	 information  for  all
		 volumes  in the file system's volume set.  If only one volume
		 is specified, the volume name is suppressed  in  the  output.

       To report files that have extents on a single volume:

	      # fsvmap /dev/vx/rdsk/fstest/testvset vol1

       To report files that have extents on any of multiple volumes:

	      # fsvmap /dev/vx/rdsk/fstest/testvset vol1 vol2
	      vol1    /.
	      vol1    /ns2
	      vol1    /ns3
	      vol1    /file1
	      vol2    /file1
	      vol2    /file2

       To  report  files  from	all Storage Checkpoints that have extents on a
       single volume:

	      # fsvmap -C /dev/vx/rdsk/fstest/testvset vol1
	      UNNAMED	 /.
	      UNNAMED	 /file1
	      UNNAMED	 /ns2
	      UNNAMED	 /ns3
	      c1	 /file1

       To report files that have extents, either data or metadata, on a single

	      # fsvmap -m /dev/vx/rdsk/fstest/testvset vol1
	      Data    /.
	      Data    /file1
	      Meta    /file1
	      Data    /ns2
	      Data    /ns3
	      Meta    /has_dattr

       To report files from all Storage Checkpoints that have data or metadata
       extents on any volume in the file system and indicate if the volume has
       file system metadata:

	      # fsvmap -mvC /dev/vx/rdsk/fstest/testvset
	      Meta    STRUCTURAL   vol1	   //volume has filesystem metadata//
	      Data    UNNAMED	   vol1	   /.
	      Data    UNNAMED	   vol1	   /ns2
	      Data    UNNAMED	   vol1	   /ns3
	      Data    UNNAMED	   vol1	   /file1
	      Meta    UNNAMED	   vol1	   /file1
