DESCRIPTION

       The vos listvol command formats and displays the following information from the volume
       header of each specified volume: volume name, volume ID, volume type, size, and status at
       the server. The actual information displayed depends on the combination of arguments
       supplied when the command is issued. To display volume header information for various
       numbers of volumes, combine the command's arguments as indicated:

       •   For every volume on a file server machine, specify the machine's name with the -server
           argument.

       •   For every volume at a particular site, combine the -server argument with the
           -partition argument.

       To display the Volume Location Database (VLDB) entry for one or more volumes, use the vos
       listvldb command. To display both the VLDB entry and the volume header for a single
       volume, use the vos examine command.

OPTIONS

       -server <server name>
           Identifies the file server machine that houses volumes for which to display the
           header. Provide the machine's IP address or its host name (either fully qualified or
           using an unambiguous abbreviation). For details, see vos(1).

           This argument can be combined with the -partition argument, as well as the -fast,
           -long, or -extended flag.

       -partition <partition name>
           Identifies the partition (on the file server machine specified by the -server
           argument) that houses volumes for which to display the header. Provide the partition's
           complete name with preceding slash (for example, /vicepa) or use one of the three
           acceptable abbreviated forms. For details, see vos(1).

       -fast
           Displays only the volume ID numbers of volumes stored at the site specified by the
           -server, and optionally -partition, argument. Do not combine this flag with the
           -extended flag.

       -long
           Displays more detailed information about each volume stored at the site specified by
           the -server, and optionally -partition, argument. The information includes the volume
           IDs of all three volume types associated with the volume, and the read/write volume's
           quota, creation date and update date.

       -quiet
           Suppresses the lines that summarize the number of volumes listed and their status,
           which otherwise appear at the beginning and end of the output when the output includes
           more than one volume.

       -extended
           Displays extensive statistics about access patterns for each volume stored at the site
           specified by the -server, and optionally -partition, argument. The statistics include
           the number of reads and writes to files in the volume, and how recently files and
           directories have been updated by their owners or other users. Do not combine this flag
           with the -fast flag.

       -format
           Show information in a format suitable for machine parsing.

       -cell <cell name>
           Names the cell in which to run the command. Do not combine this argument with the
           -localauth flag. For more details, see vos(1).

       -noauth
           Assigns the unprivileged identity "anonymous" to the issuer. Do not combine this flag
           with the -localauth flag. For more details, see vos(1).

       -localauth
           Constructs a server ticket using a key from the local /etc/openafs/server/KeyFile
           file. The vos command interpreter presents it to the Volume Server and Volume Location
           Server during mutual authentication. Do not combine this flag with the -cell argument
           or -noauth flag. For more details, see vos(1).

       -verbose
           Produces on the standard output stream a detailed trace of the command's execution. If
           this argument is omitted, only warnings and error messages appear.

       -encrypt
           Encrypts the command so that the operation's results are not transmitted across the
           network in clear text. This option is available in OpenAFS versions 1.4.11 or later
           and 1.5.60 or later.

       -noresolve
           Shows all servers as IP addresses instead of the DNS name. This is very useful when
           the server address is registered as 127.0.0.1 or when dealing with multi-homed
           servers. This option is available in OpenAFS versions 1.4.8 or later and 1.5.35 or
           later.

       -config <configuration directory>
           Set the location of the configuration directory to be used. This defaults to
           /etc/openafs, except if -localauth is specified, in which case the default is
           /etc/openafs/server. This option allows the use of alternative configuration locations
           for testing purposes.

       -help
           Prints the online help for this command. All other valid options are ignored.

OUTPUT

       The output is ordered alphabetically by volume name and by default provides the following
       information on a single line for each volume:

       •   Name

       •   Volume ID number

       •   Type (the flag is "RW" for read/write, "RO" for read-only, "BK" for backup)

       •   Size in kilobytes (1024 equals a megabyte)

       •   Number of files in the volume, if the -extended flag is provided

       •   Status on the file server machine, which is one of the following:

           On-line
               The volume is completely accessible to Cache Managers.

           Off-line
               The volume is not accessible to Cache Managers, but does not seem to be corrupted.
               This status appears while a volume is being dumped, for example.

           Off-line**needs salvage**
               The volume is not accessible to Cache Managers, because it seems to be corrupted.
               Use the bos salvage or salvager command to repair the corruption.

       If the following message appears instead of the previously listed information, it
       indicates that a volume is not accessible to Cache Managers or the vos command
       interpreter, for example because a clone is being created.

          **** Volume <volume_ID> is busy ****

       If the following message appears instead of the previously listed information, it
       indicates that the File Server is unable to attach the volume, perhaps because it is
       seriously corrupted. The FileLog and VolserLog log files in the /var/log/openafs directory
       on the file server machine possibly provide additional information; use the bos getlog
       command to display them.

          **** Could not attach volume <volume_ID> ****

       The information about individual volumes is bracketed by summary lines. The first line of
       output specifies the number of volumes in the listing. The last line of output summarizes
       the number of volumes that are online, offline, and busy. These lines do not appear if the
       -quiet flag is used.

       If the -fast flag is added, the output displays only the volume ID number of each volume,
       arranged in increasing numerical order. The final line (which summarizes the number of
       online, offline, and busy volumes) is omitted.

       If the -long flag is included, the output for each volume includes all of the information
       in the default listing plus the following. Each item in this list corresponds to a
       separate line of output:

       •   The file server machine and partition that house the volume, as determined by the
           command interpreter as the command runs, rather than derived from the VLDB or the
           volume header.

       •   The volume ID numbers associated with the various versions of the volume: read/write
           ("RWrite"), read-only ("ROnly"), backup ("Backup"), and ReleaseClone ("RClone"). One
           of them matches the volume ID number that appears on the first line of the volume's
           output. If the value in the "RWrite", "ROnly", or "Backup" field is 0 (zero), there is
           no volume of that type. If there is currently no ReleaseClone, the "RClone" field does
           not appear at all.

       •   The maximum space quota allotted to the read/write copy of the volume, expressed in
           kilobyte blocks in the "MaxQuota" field.

       •   The date and time the volume was created, in the "Creation" field. If the volume has
           been restored with the backup diskrestore, backup volrestore, or vos restore command,
           this is the restore time.

       •   The date and time when the contents of the volume last changed, in the "Last Update"
           field. For read-only and backup volumes, it matches the timestamp in the "Creation"
           field.

       •   The number of times the volume has been accessed for a fetch or store operation since
           the later of the two following times:

           •   12:00 a.m. on the day the command is issued

           •   The last time the volume changed location

       If the -extended flag is included, the output for each volume includes all of the
       information reported with the -long flag, plus two tables of statistics:

       •   The table labeled "Raw Read/Write Stats" table summarizes the number of times the
           volume has been accessed for reading or writing.

       •   The table labeled "Writes Affecting Authorship" table contains information on writes
           made to files and directories in the specified volume.

EXAMPLES

       The following example shows the output for the /vicepb partition on the file server
       machine "fs2.example.com" when no flags are provided:

          % vos listvol -server fs2.example.com -partition b
          Total number of volumes on server fs2.example.com partition /vicepb : 66
