| 3 | salvage.lock - Prevents multiple simultaneous salvage operations on a partition | |
| 4 | ||
| 5 | =head1 DESCRIPTION | |
| 6 | ||
| 7 | The F<salvage.lock> file guarantees that only one Salvager (B<salvager> | |
| 8 | process) runs at a time on a file server machine (the single process can | |
| 9 | fork multiple subprocesses to salvage multiple partitions in parallel). As | |
| 10 | the Salvager initializes, it creates the empty (zero-length) file in the | |
| 11 | F</usr/afs/local> directory and invokes the B<flock> system call on it. It | |
| 12 | removes the file when it completes the salvage operation. Because the | |
| 13 | Salvager must lock the file to run, only one Salvager can run at a time. | |
