</PRE>
|
|
<P><STRONG>Description</STRONG>
|
|
<P>The <B>vos status</B> 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:
|
|
<PRE> No active transactions on <VAR>machine_name</VAR>
|
|
|
|
</PRE>
|
|
<P>This command is useful mainly if there is concern that the Volume Server is
|
|
not performing requested actions.
|
|
<P><STRONG>Options</STRONG>
|
|
<DL>
|
|
<P><DT><B><B>-server</B>
|
|
</B><DD>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 the introductory reference page for the
|
|
<B>vos</B> command suite.
|
|
<P><DT><B>-cell
|
|
</B><DD>Names the cell in which to run the command. Do not combine this
|
|
argument with the <B>-localauth</B> flag. For more details, see the
|
|
introductory <B>vos</B> reference page.
|
|
<P><DT><B>-noauth
|
|
</B><DD>Assigns the unprivileged identity <B>anonymous</B> to the
|
|
issuer. Do not combine this flag with the <B>-localauth</B>
|
|
flag. For more details, see the introductory <B>vos</B> reference
|
|
page.
|
|
<P><DT><B>-localauth
|
|
</B><DD>Constructs a server ticket using a key from the local
|
|
<B>/usr/afs/etc/KeyFile</B> file. The <B>vos</B> command
|
|
interpreter presents it to the Volume Server and Volume Location Server during
|
|
mutual authentication. Do not combine this flag with the
|
|
<B>-cell</B> argument or <B>-noauth</B> flag. For more details,
|
|
see the introductory <B>vos</B> reference page.
|
|
<P><DT><B>-verbose
|
|
</B><DD>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.
|
|
<P><DT><B>-help
|
|
</B><DD>Prints the online help for this command. All other valid options
|
|
are ignored.
|
|
</DL>
|
|
<P><STRONG>Output</STRONG>
|
|
<P>There are two possible types of output.
|
|
<P>The following message indicates that the Volume Server is not currently
|
|
performing any actions.
|
|
<PRE> No active transactions on <VAR>machine name</VAR>
|
|
|
|
</PRE>
|
|
<P>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.
|
|
<P>Among the fields of possible interest to an administrator are:
|
|
<UL>
|
|
<P><LI><TT>created</TT> on the first line, which indicates the time at which
|
|
this transaction started
|
|
<P><LI><TT>attachFlags</TT> on the second line, where a value of
|
|
<TT>offline</TT> indicates that the volume is not available for other read
|
|
or write operations during this transaction
|
|
<P><LI><TT>volume</TT> on the third line, which specifies the affected
|
|
volume's ID number
|
|
<P><LI><TT>partition</TT> on the third line, which indicates where the affected
|
|
volume resides (at the beginning of the transaction if this is a move)
|
|
<P><LI><TT>procedure</TT> on the third line, which indicates the internal
|
|
subprocedure being executed
|
|
</UL>
|
|
<P>A fourth line can appear during certain transactions, and includes the
|
|
following fields:
|
|
<UL>
|
|
<P><LI><TT>packetRead</TT> tracks whether information is being read into the
|
|
volume. Its absolute value is not informative, but the way it changes
|
|
shows whether the <B>vos restore</B> command is executing properly.
|
|
As the <B>vos status</B> command is issued repeatedly during a restore,
|
|
<TT>readNext</TT> increases monotonically to indicate that information is
|
|
being read into the volume.
|
|
<P><LI><TT>packetSend</TT> tracks whether information is being sent out of the
|
|
volume. Its absolute value is not informative, but the way it changes
|
|
shows whether the <B>vos dump</B> command is executing properly. As
|
|
the <B>vos status</B> command is issued repeatedly during a dump,
|
|
<TT>transmitNext</TT> increases monotonically to indicate that information
|
|
is being transferred from the volume into the dump file.
|
|
</UL>
|
|
<P>The <TT>lastReceiveTime</TT> and <TT>lastSendTime</TT> are for internal
|
|
use.
|
|
<P><STRONG>Examples</STRONG>
|
|
<P>The following example illustrates the kind of output that sometimes appears
|
|
when the Volume Server on <B>fs1.abc.com</B> is executing a
|
|
dump at the time this command is issued.
|
|
<PRE> % <B>vos status fs1.abc.com</B>
