<P><STRONG>Purpose</STRONG>
|
||
|
|
<P>Prevents multiple simultaneous salvage operations on a partition
|
||
|
|
<P><STRONG>Description</STRONG>
|
||
|
|
<P>The <B>salvage.lock</B> file guarantees that only one Salvager
|
||
|
|
(<B>salvager</B> 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</B> directory and invokes the
|
||
|
|
<B>flock</B> 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.
