    SYNOPSIS

           vos examine -id <volume name or ID> [-extended]
               [-format] [-cell <cell name>]
               [-noauth] [-localauth] [-verbose]
               [-encrypt] [-noresolve] [-help]
    
           vos e -i <volume name or ID> [-ex] [-f]
               [-c <cell name>]
               [-noa] [-l] [-v] [-e] [-nor] [-h]
    
           vos volinfo -id <volume name or ID> [-extended]
               [-format] [-cell <cell name>]
               [-noauth] [-localauth] [-verbose]
               [-encrypt] [-noresolve] [-help]
    
           vos v -i <volume name or ID> [-ex] [-f]

               [-noa] [-l] [-v] [-e] [-nor] [-h]
    
    
    

    DESCRIPTION

           The vos examine command formats and displays information from the
           Volume Location Database (VLDB) entry and the volume header of the
           volume specified by the -id argument.
    
           To display the volume header only, use the vos listvol command. To
           display information from the VLDB only, use the vos listvldb command.
    
    
    

    CAUTIONS

           Currently, the maximum size of a volume is 2 terabytes (2^31 bytes).
    
    
    

    OPTIONS

           -id <volume name or ID>
               Specifies either the complete name or volume ID number of the
               volume, which can be read/write, read-only, or backup.
    
           -extended
               Displays statistics about read and write operations on files and
               directories in the volume.
    
           -format
               Shows 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).
    
               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.
    
           -help
               Prints the online help for this command. All other valid options
               are ignored.
    
    
    

    OUTPUT

           The first seven lines of the output show information from the volume
           header and the remaining lines come from the VLDB. Each item in the
           following list corresponds to a line of output derived from the volume
           header.
    
           ?   Basic information about the specified volume (displayed on a single
               line):
    
               ?   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.
    
           ?   The file server machine and partition that house the volume, as
               determined by the command interpreter as the command runs, rather
               If the volume has been restored with the backup diskrestore, backup
               volrestore, or vos restore command, this is the restore time. For a
               read-only volume, this is the last release time.
    
           ?   The date and time this copy of this volume was created, in the
               "Copy" field.  This is the time when the volume was created on this
               server and partition.  For read-only volumes, it is not updated by
               a release (unlike the Creation date).  The copy date is not stored
               in volume dumps.
    
           ?   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
    
           When the -extended flag is included, two tables appear next:
    
           ?   The table labeled "Raw Read/Write Stats" contains information on
               the number of reads (fetches) and writes (stores) made on the
               specified volume.
    
           ?   The table labeled "Writes Affecting Authorship" contains
               information on writes made to files and directories in the
               specified volume.
    
           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> ****
    
           Following a blank line, information from the VLDB entry appears.  Each
           item in this list corresponds to a separate line in the output:
    
           ?   The base (read/write) volume name. The read-only and backup
               versions have the same name with a ".readonly" and ".backup"
    
           ?   A line for each site that houses a read/write or read-only copy of
               the volume, specifying the file server machine, partition, and type
               of volume ("RW" for read/write or "RO" for read-only). If a backup
               version exists, it is understood to share the read/write site.
               Several flags can appear with a site definition:
    
               Not released
                   Indicates that the vos release command has not been issued
                   since the vos addsite command was used to define the read-only
                   site.
    
               Old release
                   Indicates that a vos release command did not complete
                   successfully, leaving the previous, obsolete version of the
                   volume at this site.
    
               New release
                   Indicates that a vos release command did not complete
                   successfully, but that this site did receive the correct new
                   version of the volume.
    
           ?   If the VLDB entry is locked, the string "Volume is currently
               LOCKED", as well as (in OpenAFS 1.5.75 and later) one or more of
               the following strings:
    
               Volume is locked for a move operation
                   Indicates that the volume was locked due to a vos move or a vos
                   convertROtoRW command.
    
               Volume is locked for a release operation
                   Indicates that the volume was locked due to a vos release
                   command.
    
               Volume is locked for a backup operation
                   Indicates that the volume was locked due to a vos backup
                   command.
    
               Volume is locked for a delete/misc operation
                   Indicates that the volume was locked due to a vos delentry, vos
                   addsite, vos remsite, vos changeloc, vos syncvldb, vos
                   syncserv, vos rename, or vos lock command.
    
               Volume is locked for a dump/restore operation
                   Indicates that the volume was locked due to a vos dump or vos
                   restore command.
    
           For further discussion of the "New release" and "Old release" flags,
           see vos_release(1).
    
    
    

    EXAMPLES
