| 3 | fs_uuid - Prints the uuid of the client or generates a new one | |

| 15 | =head1 DESCRIPTION | |
| 16 | ||
| 17 | B<fs uuid> prints the current UUID of an OpenAFS client. It can | |
| 18 | optionally force the generation of a new UUID, if needed. The client UUID | |
| 19 | is used by the B<fileserver> to differentiate clients with the same IP | |
| 20 | address. | |
| 21 | ||
| 22 | =head1 CAUTIONS | |
| 23 | ||
| 24 | The B<fs uuid> command is only available in OpenAFS versions after 1.4.5 | |
| 25 | and 1.5.8. The behavior differs slightly between versions. In OpenAFS | |
| 26 | 1.4.5 and later, the B<-generate> option is required and the UUID for the | |
| 27 | client machine is never printed. OpenAFS versions 1.5.8 and later will | |
| 28 | print the UUID. | |
| 29 | ||
| 30 | =head1 OPTIONS | |
| 31 | ||
| 32 | =over 4 | |
| 33 | ||
| 34 | =item B<-generate> | |
| 35 | ||
| 36 | Generates a new UUID for the cache manager. This is useful if two clients | |
| 37 | share the same UUID (if systems were cloned incorrectly, for example). | |
| 38 | B<-generate> is optional in OpenAFS versions 1.5.8 and later, but it is | |
| 39 | required in OpenAFS versions 1.4.5 and later. | |
| 40 | ||
| 41 | =item B<-help> | |
| 42 | ||
| 43 | Prints the online help for this command. All other valid options are | |
| 44 | ignored. | |
| 45 | ||
| 46 | =back | |
| 47 | ||
| 48 | =head1 OUTPUT | |
| 49 | ||
| 50 | B<fs uuid> prints out the current UUID for the client or the new UUID | |
| 51 | if the B<-generate> option is passed to it. | |
| 52 | ||
| 53 | =head1 EXAMPLES | |
| 54 | ||
| 55 | There are only two ways to invoke B<fs uuid> under 1.5.8 and later: | |
| 56 | ||
| 57 | % fs uuid | |
| 58 | UUID: 8ac66f9308a8e-47d7-80f7-50d0040cddc2 | |
| 59 | ||
| 60 | % fs uuid -generate | |
| 61 | New UUID: 436bd660-1720-429508e470cff38f5c6fb0 | |
| 62 | ||
| 63 | Here is the only way to invoke B<fs uuid> under OpenAFS 1.4.5 and later: | |
| 64 | ||
| 65 | % fs uuid -generate | |
| 66 | New uuid generated. | |
