Make vlserver and volserver suppport a new command line parameter, "-restricted_query admin". When this is on, the query RPCs that are not needed for normal cache manager operations are restricted to administrators listed in UserList. This is off by default.

=item B<-d> <I<debug level>>
|
|
|
|
Sets the detail level for the debugging trace written to the
|
|
F</usr/afs/logs/VolserLog> file. Provide one of the following values, each
|
|
of which produces an increasingly detailed trace: C<0>, C<1>, C<5>, C<25>,
|
|
and C<125>.
|
|
|
|
=item B<-log>
|
|
|
|
Records in the /usr/afs/logs/VolserLog file the names of all users who
|
|
successfully initiate a B<vos> command. The Volume Server also records any
|
|
file removals that result from issuing the B<vos release> command with the
|
|
B<-f> flag.
|
|
|
|
=item B<-p> <I<number of processes>>
|
|
|
|
Sets the number of server lightweight processes (LWPs) to run. Provide an
|
|
integer between C<4> and C<16>. The default is C<9>.
|
|
|
|
=item B<-auditlog> <I<log path>>
|
|
|
|
Turns on audit logging, and sets the path for the audit log. The audit
|
|
log records information about RPC calls, including the name of the RPC
|
|
call, the host that submitted the call, the authenticated entity (user)
|
|
that issued the call, the parameters for the call, and if the call
|
|
succeeded or failed.
|
|
|
|
=item B<-audit-interface> (file | sysvmq)
|
|
|
|
Specifies what audit interface to use. Defaults to C<file>. See
|
|
L<fileserver(8)> for an explanation of each interface.
|
|
|
|
=item B<-udpsize> <I<size of socket buffer>>
|
|
|
|
Sets the size of the UDP buffer in bytes, which is 64 KB by
|
|
default. Provide a positive integer, preferably larger than the default.
|
|
|
|
=item B<-jumbo>
|
|
|
|
Allows the server to send and receive jumbograms. A jumbogram is
|
|
a large-size packet composed of 2 to 4 normal Rx data packets that share
|
|
the same header. The volserver does not use jumbograms by default, as some
|
|
routers are not capable of properly breaking the jumbogram into smaller
|
|
packets and reassembling them.
|
|
|
|
=item B<-nojumbo>
|
|
|
|
Deprecated; jumbograms are disabled by default.
|
|
|
|
=item B<-enable_peer_stats>
|
|
|
|
Activates the collection of Rx statistics and allocates memory for their
|
|
storage. For each connection with a specific UDP port on another machine,
|
|
a separate record is kept for each type of RPC (FetchFile, GetStatus, and
|
|
so on) sent or received. To display or otherwise access the records, use
|
|
the Rx Monitoring API.
|
|
|
|
=item B<-enable_process_stats>
|
|
|
|
Activates the collection of Rx statistics and allocates memory for their
|
|
storage. A separate record is kept for each type of RPC (FetchFile,
|
|
GetStatus, and so on) sent or received, aggregated over all connections to
|
|
other machines. To display or otherwise access the records, use the Rx
|
|
Monitoring API.
|
|
|
|
=item B<-allow-dotted-principals>
|
|
|
|
By default, the RXKAD security layer will disallow access by Kerberos
|
|
principals with a dot in the first component of their name. This is to avoid
|
|
the confusion where principals user/admin and user.admin are both mapped to the
|
|
user.admin PTS entry. Sites whose Kerberos realms don't have these collisions
|
|
between principal names may disable this check by starting the server
|
|
with this option.
|
|
|
|
=item B<-preserve-vol-stats>
|
|
|
|
Preserve volume access statistics over volume restore and reclone operations.
|
|
By default, volume access statistics are reset during volume restore and reclone
|
|
operations.
|
|
|
|
=item B<-sync> <I<sync behavior>>
|
|
|
|
This is the same as the B<-sync> option in L<fileserver(8)>. See
|
|
L<fileserver(8)>.
|
|
|
|
=item B<-logfile> <I<log file>>
|
|
|
|
Sets the file to use for server logging. If logfile is not specified and
|
|
no other logging options are supplied, this will be F</usr/afs/logs/VolserLog>.
|
|
Note that this option is intended for debugging and testing purposes.
|
|
Changing the location of the log file from the command line may result
|
|
in undesirable interactions with tools such as B<bos>.
|
|
|
|
=item B<-config> <I<configuration directory>>
|
|
|
|
Set the location of the configuration directory used to configure this
|
|
service. In a typical configuration this will be F</usr/afs/etc> - this
|
|
option allows the use of alternative configuration locations for testing
|
|
purposes.
|
|
|
|
=item B<-rxmaxmtu> <I<bytes>>
|
|
|
|
Defines the maximum size of an MTU. The value must be between the
|
|
minimum and maximum packet data sizes for Rx.
|
|
|
|
=item B<-rxbind>
|
|
|
|
Bind the Rx socket to the primary interface only. (If not specified, the Rx
|
|
socket will listen on all interfaces.)
|
|
|
|
=item B<-syslog>[=<I<syslog facility>>]
|
|
|
|
Specifies that logging output should go to syslog instead of the normal
|
|
log file. B<-syslog>=I<FACILITY> can be used to specify to which facility
|
|
the log message should be sent.
|
|
|
|
=item B<-sleep> <I<sleep_time>/I<run_time>>
|
|
|
|
This option is obsolete, and is now only accepted for compatibility with older
|
|
releases. All it does now is log a warning message about how the option is
|
|
obsolete.
|
|
|
|
=item B<-restricted_query> (anyuser | admin)
|
|
|
|
Restrict RPCs that query information about volumes to a specific group
|
|
of users. You can use C<admin> to restrict to AFS administrators. The
|
|
C<anyuser> option doesn't restrict the RPCs and leaves it open for all
|
|
users including unauthenticated users, this is the default.
|
|
|
|
=item B<-help>
|
|
|
|
Prints the online help for this command. All other valid options are
|
|
ignored.
