| 18 | =head1 DESCRIPTION | |
| 19 | ||
| 20 | The B<vldb_convert> command is used to convert legacy Transarc 3.1-3.4 | |
| 21 | VLDB database files between versions. This command is not needed when | |
| 22 | using OpenAFS except in the case of preparing to migrate a pre-3.4 version | |
| 23 | of Transarc AFS to OpenAFS. | |
| 24 | ||
| 25 | In order to convert the VLDB file, do the following: | |
| 26 | ||
| 27 | =over 4 | |
| 28 | ||
| 29 | =item 1. | |
| 30 | ||
| 31 | Shutdown the B<vlserver> process on all server machines. B<vlserver> is | |
| 32 | typically run only on the Cell servers, which must be listed in | |
| 33 | F<CellServDB> or DNS. | |
| 34 | ||
| 35 | =item 2. | |
| 36 | ||
| 37 | Backup the VLDB file F</usr/afs/db/vldb.DB0> on the sync site to a safe | |
| 38 | place. Typically, the sync site if the machine with the lowest IP address. | |
| 39 | ||
| 40 | =item 3. | |
| 41 | ||
| 42 | Remove the F</usr/afs/db/vldb.DBSYS1> file from all cell server machines. | |
| 43 | ||
| 44 | =item 4. | |
| 45 | ||
| 46 | Remove the F</usr/afs/db/vldb.DB0> file from the non-sync site server | |
| 47 | machines. | |
| 48 | ||
| 49 | =item 5. | |
| 50 | ||
| 51 | Run the B<vldb_convert> command on the VLDB file using the following | |
| 52 | command: | |
| 53 | ||
| 54 | # vldb_convert -path /usr/afs/db/vldb.DB0 | |
| 55 | ||
| 56 | =item 6. | |
| 57 | ||
| 58 | Copy the new version of the vlserver binaries to all Cell servers. | |
| 59 | ||
| 60 | =item 7. | |
| 61 | ||
| 62 | Restart the vlserver process on all Cell servers. The new VLDB will be | |
| 63 | distributed to all of the Cell servers. | |
| 64 | ||
| 65 | =item 8. | |
| 66 | ||
| 67 | Confirm that all Cell servers are synchronized and that the vldb looks in | |
| 68 | good shape. | |
| 69 | ||
| 70 | =back | |
| 71 | ||
| 72 | =head1 CAUTIONS | |
| 73 | ||
| 74 | Backup the VLDB file to a different directory or machine before performing | |
| 75 | the upgrade. Be sure that all vlserver processes are always running the | |
| 76 | same version. This requires downtime, but for this conversion, all | |
| 77 | vlserver instances must be at the same version. This restriction is | |
| 78 | relaxed in OpenAFS. | |
| 79 | ||
| 80 | =head1 OPTIONS | |
| 81 | ||
| 82 | =over 4 | |
| 83 | ||
| 84 | =item B<initcmd> | |
| 85 | ||
| 86 | This is an optional string that does nothing. | |
| 87 | ||
| 88 | =item B<-to> <I<AFS version goal>> | |
| 89 | ||
| 90 | This option is required when downgrading or when upgrading to a version | |
| 91 | less than 3.4. Specify 1, 2, 3, or 4 to choose version 3.1, 3.2, 3.3, or | |
| 92 | 3,4 respectively. This defaults to version 3.4. | |
| 93 | ||
| 94 | =item B<-from> <I<current AFS version>> | |
| 95 | ||
| 96 | This option is required when downgrading. Specify 1, 2, 3, or 4 to choose | |
| 97 | version 3.1, 3.2, 3.3, or 3.4 respectively. | |
| 98 | ||
| 99 | =item B<-path> <I<path to VLDB file>> | |
| 100 | ||
| 101 | Specifies the path the VLDB file. This defaults to F</usr/afs/db/vldb.DB0> | |
| 102 | and only needs to be used if the VLDB file is not in the default path.. | |
| 103 | ||
| 104 | =item B<-showversion> | |
| 105 | ||
| 106 | Shows the current version of the VLDB. This option can only be used by itself. | |
| 107 | ||
| 108 | =item B<-dumpvldb> | |
| 109 | ||
| 110 | Produces verbose debugging output during the conversion process. | |
| 111 | ||
| 112 | =item B<-help> | |
| 113 | ||
| 114 | Prints the online help for this command. All other valid options are | |
| 115 | ignored. | |
| 116 | ||
| 117 | =back | |
| 118 | ||
| 119 | =head1 PRIVILEGE REQUIRED | |
| 120 | ||
| 121 | The issuer must have read and write access to the file | |
| 122 | F</usr/afs/db/vldb.DB0>. This usually means that root access is required | |
| 123 | on the cell server machines. | |
