| 30 | =head1 DESCRIPTION | |
| 31 | ||
| 32 | The B<vos syncvldb> command verifies that the status of the volumes housed | |
| 33 | either on all partitions on the file server machine specified by the | |
| 34 | B<-server> argument, or on the single partition specified by the | |
| 35 | B<-server> and B<-partition> arguments, is recorded correctly in the | |
| 36 | VLDB. If the B<-volume> argument is included to indicate a single volume, | |
| 37 | the command compares only its status on the file server machine with its | |
| 38 | VLDB entry. | |
| 39 | ||
| 40 | If the B<-volume> argument is not included, the command interpreter | |
| 41 | obtains from the Volume Server a list of the volumes that reside on each | |
| 42 | partition, then changes information in the VLDB as necessary to reflect | |
| 43 | their state on the partition. For example, it creates or updates a VLDB | |
| 44 | entry when it finds a volume for which the VLDB entry is missing or | |
| 45 | incomplete. However, if there is already a VLDB entry that defines a | |
| 46 | different location for the volume, or there are irreconcilable conflicts | |
| 47 | with other VLDB entries, it instead writes a message about the conflict to | |
| 48 | the standard error stream. The command never removes volumes from the file | |
| 49 | server machine. | |
| 50 | ||
| 51 | To achieve complete VLDB consistency, run this command on all file server | |
| 52 | machines in the cell, and then run the B<vos syncserv> command on all file | |
| 53 | server machines in the cell. | |
| 54 | ||
| 55 | Using the B<-volume> argument basically combines the effects of this | |
| 56 | command with those of the B<vos syncserv> command, for a single | |
| 57 | volume. The command not only verifies that the VLDB entry is correct for | |
| 58 | the specified volume type (read/write, backup, or read-only), but also | |
| 59 | checks that any related volume types mentioned in the VLDB entry actually | |
| 60 | exist at the site listed in the entry. It is not necessary to provide the | |
| 61 | B<-server> argument (and optionally, B<-partition> argument); if one or | |
| 62 | both is provided, the results are reliable only if they specify the actual | |
| 63 | location of the volume indicated by the B<-volume> argument. | |

| 65 | =head1 OPTIONS | |
| 66 | ||
| 67 | =over 4 | |
| 68 | ||
| 69 | =item B<-server> <I<server name>> | |
| 70 | ||
| 71 | Identifies the file server machine housing the volumes for which to verify | |
| 72 | VLDB entries. Provide the machine's IP address or its host name (either | |
| 73 | fully qualified or using an unambiguous abbreviation). For details, see | |
| 74 | L<vos(1)>. | |
| 75 | ||
| 76 | =item B<-partition> <I<partition name>> | |
| 77 | ||
| 78 | Identifies the partition housing the volumes for which to verify VLDB | |
| 79 | entries. Provide the B<-server> argument along with this one. Provide the | |
| 80 | partition's complete name with preceding slash (for example, C</vicepa>) | |
| 81 | or use one of the three acceptable abbreviated forms. For details, see | |
| 82 | L<vos(1)>. | |
| 83 | ||
| 84 | =item B<-volume> <I<volume name or ID>> | |
| 85 | ||
| 86 | Specifies the name or volume ID number of a single volume for which to | |
| 87 | verify the VLDB entry. This argument can be combined with the B<-server> | |
| 88 | (and optionally, the B<-partition>) argument. | |
| 89 | ||
| 90 | =item B<-dryrun> | |
| 91 | ||
| 92 | Show the actions which would be taken, but do not make changes. | |
| 93 | ||

| 97 | ||
| 98 | =head1 EXAMPLES | |
| 99 | ||
| 100 | The following example command verifies the VLDB entry for each volume | |
| 101 | stored on the file server machine C<fs4.example.com>. | |
| 102 | ||
| 103 | % vos syncvldb fs4.example.com | |
| 104 | ||
| 105 | =head1 PRIVILEGE REQUIRED | |
| 106 | ||
| 107 | The issuer must be listed in the F</usr/afs/etc/UserList> file on the | |
| 108 | machine specified with the B<-server> argument and on each database server | |
| 109 | machine. If the B<-localauth> flag is included, the issuer must instead be | |
| 110 | logged on to a server machine as the local superuser C<root>. | |
