NAME

       vos_listvol - Displays information from a volume header

SYNOPSIS

       vos listvol -server <machine name>
           [-partition <partition name>] [-fast] [-long] [-quiet]
           [-extended] [-cell <cell name>] [-noauth] [-localauth]
           [-verbose] [-help]

       vos listvo -s <machine name> [-p <partition name>] [-f]
           [-lon] [-q] [-e] [-c <cell name>] [-n] [-loc]
           [-v] [-h]

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.

       -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.

       -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.abc.com" when no flags are provided:

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

       The following example shows two volumes from the output that appears
       when the -long flag is added:
