<title>Description</title>
|
|
<para>The <replaceable>salvage.lock</replaceable> file guarantees that only one Salvager (<emphasis role="bold">salvager</emphasis>
|
|
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
|
|
<replaceable>/usr/afs/local</replaceable> directory and invokes the <emphasis role="bold">flock</emphasis> 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.</para>
