NAME
vos_listvldb - Displays a volume’s VLDB entry
SYNOPSIS
vos listvldb [-name <volume name or ID>]
[-server <machine name>] [-partition <partition name>]
[-locked] [-quiet] [-nosort] [-cell <cell name>]
[-noauth] [-localauth] [-verbose] [-help]
vos listvl [-na <volume name or ID>] [-s <machine name>]
[-p <partition name>] [-lock] [-q] [-nos]
[-c <cell name>] [-noa] [-loca] [-v] [-h]
DESCRIPTION
The vos listvldb command formats and displays information from the
Volume Location Database (VLDB) entry for each volume specified. The
output depends on the combination of options supplied on the command
line. Combine options as indicated to display the desired type of VLDB
entries:
· Every entry in the VLDB: provide no options.
· Every VLDB entry that mentions a certain file server machine as the
site for a volume: specify the machine’s name as the -server
argument.
· Every VLDB entry that mentions a certain partition on any file
server machine as the site for a volume: specify the partition name
as the -partition argument.
· Every VLDB entry that mentions a certain partition on a certain
file server machine as the site for a volume: combine the -server
and -partition arguments.
· A single VLDB entry: specify a volume name or ID number with the
-name argument.
· The VLDB entry only for the volumes with locked VLDB entries found
at a certain site: combine the -locked flag with any of arguments
that define sites.
OPTIONS
-name <volume name or ID>
Specifies either the complete name or volume ID number of a volume
of any of the three types.
-server <server name>
Identifies the file server machine listed as a site in each VLDB
entry to display. 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, the
-locked flag, or both.
-partition <partition name>
Identifies the partition (on the file server machine specified by
the -server argument) listed as a site in each VLDB entry to
display. 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).
This argument can be combined with the -server argument, the
-locked flag, or both.
-locked
Displays only locked VLDB entries. This flag can be combined with
the -server argument, the -partition argument, or both.
-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.
-nosort
Suppresses the default sorting of volume entries alphabetically by
volume name.
-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
If the output includes more than one VLDB entry, by default the first
line reports which file server machine, partition, or both, houses the
volumes. The final line of output reports the total number of entries
displayed. Including the -quiet flag suppresses these lines.
By default, volumes are sorted alphabetically by volume name.
Including the -nosort flag skips the sorting step, which can speed up
the production of output if there are a large number of entries.
The VLDB entry for each volume includes the following information:
· The base (read/write) volume name. The read-only and backup
versions have the same name with a ".readonly" and ".backup"
extension, respectively.
· The volume ID numbers allocated to the versions of the volume that
actually exist, in fields labeled "RWrite" for the read/write,
"ROnly" for the read-only, "Backup" for the backup, and "RClone"
for the ReleaseClone. (If a field does not appear, the
corresponding version of the volume does not exist.) The appearance
of the "RClone" field normally indicates that a release operation
did not complete successfully; the "Old release" and "New release"
flags often also appear on one or more of the site definition lines
described just following.
· The number of sites that house a read/write or read-only copy of
the volume, following the string "number of sites ->".
· 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".
For further discussion of the "New release" and "Old release" flags,
see vos_release(1).
EXAMPLES
The following command displays VLDB information for the ABC Corporation
volume called "usr", which has two read-only replication sites:
% vos listvldb -name usr
usr
RWrite: 5360870981 ROnly: 536870982 Backup: 536870983
number of sites -> 3
server fs1.abc.com partition /vicepa RO Site
server fs3.abc.com partition /vicepa RO Site
server fs2.abc.com partition /vicepb RW Site
The following example shows entries for two of the volumes that reside
on the file server machine "fs4.abc.com". The first VLDB entry is
currently locked. There are 508 entries that mention the machine as a
volume site.
% vos listvldb -server fs4.abc.com
VLDB entries for server fs4.abc.com
