<P><STRONG>Description</STRONG>
|
||
|
|
<P>The <B>vos syncvldb</B> command verifies that the status of the volumes
|
||
|
|
housed either on all partitions on the file server machine specified by the
|
||
|
|
<B>-server</B> argument, or on the single partition specified by the
|
||
|
|
<B>-server</B> and <B>-partition</B> arguments, is recorded correctly
|
||
|
|
in the VLDB. If the <B>-volume</B> argument is included to indicate
|
||
|
|
a single volume, the command compares only its status on the file server
|
||
|
|
machine with its VLDB entry.
|
||
|
|
<P>If the <B>-volume</B> argument is not included, the command interpreter
|
||
|
|
obtains from the Volume Server a list of the volumes that reside on each
|
||
|
|
partition, then changes information in the VLDB as necessary to reflect their
|
||
|
|
state on the partition. For example, it creates or updates a VLDB entry
|
||
|
|
when it finds a volume for which the VLDB entry is missing or
|
||
|
|
incomplete. However, if there is already a VLDB entry that defines a
|
||
|
|
different location for the volume, or there are irreconcilable conflicts with
|
||
|
|
other VLDB entries, it instead writes a message about the conflict to the
|
||
|
|
standard error stream. The command never removes volumes from the file
|
||
|
|
server machine.
|
||
|
|
<P>To achieve complete VLDB consistency, run this command on all file server
|
||
|
|
machines in the cell, and then run the <B>vos syncserv</B> command on all
|
||
|
|
file server machines in the cell.
|
||
|
|
<P>Using the <B>-volume</B> argument basically combines the effects of
|
||
|
|
this command with those of the <B>vos syncserv</B> command, for a single
|
||
|
|
volume. The command not only verifies that the VLDB entry is correct
|
||
|
|
for the specified volume type (read/write, backup, or read-only), but also
|
||
|
|
checks that any related volume types mentioned in the VLDB entry actually
|
||
|
|
exist at the site listed in the entry. It is not necessary to provide
|
||
|
|
the <B>-server</B> argument (and optionally, <B>-partition</B>
|
||
|
|
argument); if one or both is provided, the results are reliable only if
|
||
|
|
they specify the actual location of the volume indicated by the
|
||
|
|
<B>-volume</B> argument.

<P>The issuer must be listed in the <B>/usr/afs/etc/UserList</B> file on

the machine specified with the <B>-server</B> argument and on each
