NAME

vos_listvol - Displays information from a volume header

SYNOPSIS

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

vos listvo -s <machine name> [-p <partition name>] [-fa] [-lon] [-q] [-ex] [-fo] [-c <cell name>] [-noa] [-loc] [-v] [-en] [-nor] [-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:

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 /usr/afs/etc/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.

-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:

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 /usr/afs/logs 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:

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:

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
   sys                  1969534847 RW       1582 K On-line

   user.pat.backup      1969534538 BK      17537 K On-line
   Total volumes onLine 66 ; Total volumes offLine 0 ;  Total busy 0

The following example shows the output when the -fast flag is added:

   % vos listvol -server fs2.abc.com -partition b -fast
   Total number of volumes on server fs2.abc.com partition /vicepb : 66
    1969516782
    1969516784
        .
        .
    1969535796

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

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