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