=head1 DESCRIPTION

The B<vos endtrans> command ends a specific transaction on the Volume
Server for a specific volume. Under normal operation this command should
never need to be used, but it can be useful to reduce the amount of time
a volume is offline after an accidental command, or a L<B<vos>|vos(1)>
process crash.

Many L<B<vos>|vos(1)> commands, when they interact with a volume, create
what is called a transaction in order to perform many different
operations on a volume. If the L<B<vos>|vos(1)> process exits uncleanly,
transactions may still stay open for the manipulated volumes, and the
Volume Server may deny any further operations on those volumes while the
transactions are still open. B<vos endtrans> allows you to end these
transactions and make the volumes usable again without needing to
restart the volserver.

To find out what transactions are running on a Volume Server and what
their transaction IDs are, see the L<B<vos status>|vos_status(1)>
command.

=head1 CAUTIONS

This command is not used during normal OpenAFS administration. If used
improperly, this can negatively impact currently-running
L<B<vos>|vos(1)> operations. Only run this on a transaction if you are
certain that the program that created the transaction is no longer
running.

=head1 OPTIONS

=over 4

=item B<-server> <I<server name>>

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

=item B<-transaction> <I<transaction ID>>

Identifies which transaction to end on the Volume Server. You can get a
listing of active transactions and their IDs from the output of
L<B<vos status>|vos_status(1)>.

=head1 EXAMPLES

The following example illustrates the kind of output that can appear
when a volume operation was about to be attempted on the Volume Server
on C<fs1.example.com>, but the process performing the operation never
actually did anything with the volume:

   % vos status fs1.example.com
   --------------------------------------------
   transaction: 575  created: Fri Oct 16 16:55:54 2009
   attachFlags: offline
   volume: 536871080 partition: /vicepb procedure: TransCreate
   --------------------------------------------
   % vos endtrans fs1.example.com 575
   % vos status fs1.example.com
   No active transactions on fs1.example.com

=head1 PRIVILEGE REQUIRED

The issuer must be listed in the F</usr/afs/etc/UserList> file on the
machine specified with the B<-server> argument. If the B<-localauth>
flag is included, the issuer must instead be logged on to a server
machine as the local superuser C<root>.
