NAME

vos_status - Reports a Volume Server's status

SYNOPSIS

vos status -server <machine name>
[-cell <cell name>]
[-noauth] [-localauth]
[-verbose] [-encrypt] [-noresolve] [-help]

vos st -s <machine name>
[-c <cell name>]
[-noa] [-l] [-v] [-e] [-nor] [-h]

DESCRIPTION

The vos status command reports on what the Volume Server on a certain file server machine
is doing at the moment the command is issued. If there is no activity, the following
message appears:

No active transactions on <machine_name>

This command is useful mainly if there is concern that the Volume Server is not performing
requested actions.

OPTIONS

-server <server name>
Identifies the file server machine running the Volume Server for which to display
status information. Provide the machine's IP address or its host name (either fully
qualified or using an unambiguous abbreviation). For details, see vos(1).

-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.

-help
Prints the online help for this command. All other valid options are ignored.

OUTPUT

There are two possible types of output.

The following message indicates that the Volume Server is not currently performing any
actions.

No active transactions on I<machine name>

The other possible output is a set of information which is probably more useful to
programmers than to system administrators. A full understanding of all the fields requires
familiarity with the code for the Volume Server, as many of the fields report ID numbers
and flag values that the Volume Server sets for internal use.

Among the fields of possible interest to an administrator are:

· "created" on the first line, which indicates the time at which this transaction
started

· In OpenAFS 1.5.75 and later, "lastActiveTime" on the second line, which indicates the
last time an RPC interacted with this transaction

· "attachFlags" on the third line, where a value of "offline" indicates that the volume
is not available for other read or write operations during this transaction

· "volume" on the fourth line, which specifies the affected volume's ID number

· "partition" on the fourth line, which indicates where the affected volume resides (at
the beginning of the transaction if this is a move)

· "procedure" on the fourth line, which indicates the internal subprocedure being
executed

A fifth line can appear during certain transactions, and includes the following fields:

· "packetRead" tracks whether information is being read into the volume. Its absolute
value is not informative, but the way it changes shows whether the vos restore command
is executing properly. As the vos status command is issued repeatedly during a
restore, "readNext" increases monotonically to indicate that information is being read
into the volume.

· "packetSend" tracks whether information is being sent out of the volume. Its absolute
value is not informative, but the way it changes shows whether the vos dump command is
executing properly. As the vos status command is issued repeatedly during a dump,
"transmitNext" increases monotonically to indicate that information is being
transferred from the volume into the dump file.

The "lastReceiveTime" and "lastSendTime" are for internal use.

EXAMPLES

The following example illustrates the kind of output that sometimes appears when the
Volume Server on "fs1.abc.com" is executing a dump at the time this command is issued.

% vos status fs1.abc.com
