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.
- -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.
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.
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

The following example shows the output when the -fast flag
