=head1 DESCRIPTION
-The bos salvage command salvages (restores internal consistency
-to) one or more volumes on the file server machine named by the
-B<-server> argument. When processing one or more partitions,
-the command restores consistency to corrupted read/write volumes where
-possible. For read-only or backup volumes, it inspects only the volume
-header:

+argument. When processing one or more partitions, the command restores
+consistency to corrupted read/write volumes where possible. For read-only
+or backup volumes, it inspects only the volume header:
=over 4
If the volume header is corrupted, the Salvager removes the volume
completely and records the removal in its log file,
-B</usr/afs/logs/SalvageLog>. Issue the B<vos release>
-or B<vos backup> command to create the read-only or backup volume
-again.
-
+F</usr/afs/logs/SalvageLog>. Issue the B<vos release> or B<vos backup>
+command to create the read-only or backup volume again.
=item *
If the volume header is intact, the Salvager skips the volume (does not
-check for corruption in the contents). However, if the File Server
-notices corruption as it initializes, it sometimes refuses to attach the
-volume or bring it online. In this case, it is simplest to remove the
-volume by issuing the B<vos remove> or B<vos zap>
-command. Then issue the B<vos release> or B<vos backup>
-command to create it again.

-During the salvage of an entire machine or partition, the bos

-The Salvager always writes a trace to the

-runs. To record the trace in another file as well (either in AFS or on
-the local disk of the machine where the B<bos salvage> command is

-By default, multiple Salvager subprocesses run in parallel: one for
-each partition up to four, and four subprocesses for four or more
-partitions. To increase or decrease the number of subprocesses running
-in parallel, provide a positive integer value for the B<-parallel>
-argument.
-
-If there is more than one server partition on a physical disk, the Salvager
-by default salvages them serially to avoid the inefficiency of constantly
-moving the disk head from one partition to another. However, this
-strategy is often not ideal if the partitions are configured as logical
-volumes that span multiple disks. To force the Salvager to salvage
-logical volumes in parallel, provide the string B<all> as the value
-for the B<-parallel> argument. Provide a positive integer to
-specify the number of subprocesses to run in parallel (for example,
-B<-parallel 5all> for five subprocesses), or omit the integer to run
-up to four subprocesses, depending on the number of logical volumes being
-salvaged.
-
-The Salvager creates temporary files as it runs, by default writing them to
-the partition it is salvaging. The number of files can be quite large,
-and if the partition is too full to accommodate them, the Salvager terminates
-without completing the salvage operation (it always removes the temporary
-files before exiting). Other Salvager subprocesses running at the same
-time continue until they finish salvaging all other partitions where there is
-enough disk space for temporary files. To complete the interrupted
-salvage, reissue the command against the appropriate partitions, adding the
-B<-tmpdir> argument to redirect the temporary files to a local disk
-directory that has enough space.
-
-The -orphans argument controls how the Salvager handles orphaned
-files and directories that it finds on server partitions it is
-salvaging. An I<orphaned> element is completely inaccessible
-because it is not referenced by the vnode of any directory that can act as its
-parent (is higher in the filespace). Orphaned objects occupy space on
-the server partition, but do not count against the volume's quota.
