=head1 NAME
|
||
|
|
||
|
fms.log - Records output from the fms command
|
||
|
|
||
|
=head1 DESCRIPTION
|
||
|
|
||
|
The fms.log file records the output generated by the
|
||
|
B<fms> command. The output includes two numbers that can appear
|
||
|
in a tape device's entry in the B</usr/afs/backup/tapeconfig>
|
||
|
file on the Tape Coordinator machine to which the tape device is
|
||
|
attached:
|
||
|
|
||
|
=over 4
|
||
|
|
||
|
=item *
|
||
|
|
||
|
The capacity in bytes of the tape in the device
|
||
|
|
||
|
|
||
|
=item *
|
||
|
|
||
|
The size in bytes of the end-of-file (EOF) marks (often referred to simply
|
||
|
as I<filemarks>) that the tape device writes
|
||
|
|
||
|
|
||
|
=back
|
||
|
|
||
|
When transferring the numbers recorded in this file to the
|
||
|
B<tapeconfig> file, adjust them as specified on the reference page for
|
||
|
the B<tapeconfig> file, to improve Tape Coordinator performance during
|
||
|
dump operations.
|
||
|
|
||
|
If the fms.log file does not already exist in the current
|
||
|
working directory, the B<fms> command interpreter creates it.
|
||
|
In this case, the directory's mode bits must grant the B<rwx>
|
||
|
(B<read>, B<write>, and B<execute>) permissions to the
|
||
|
issuer of the command. If there is an existing file, the command
|
||
|
interpreter overwrites it, so the file's mode bits need to grant only the
|
||
|
B<w> permission to the issuer of the B<fms> command.
|
||
|
The B<fms> command interpreter also writes similar information to the
|
||
|
standard output stream as it runs.
|
||
|
|
||
|
The file is in ASCII format. To display its contents, log onto the
|
||
|
client machine and use a text editor or a file display command such as the
|
||
|
UNIX B<cat> command. By default, the mode bits on the
|
||
|
B<fms.log> file grant the required B<r> permission only
|
||
|
to the owner (which is the local superuser B<root> by default).
|
||
|
|
||
|
=head1 OUTPUT
|
||
|
|
||
|
The first few lines of the file provide a simple trace of the
|
||
|
B<fms> command interpreter's actions, specifying (for example)
|
||
|
how many blocks it wrote on the tape. The final two lines in the file
|
||
|
specify tape capacity and filemark size in bytes, using the following
|
||
|
format:
|
||
|
|
||
|
Tape capacity is I<tape_size> bytes
|
||
|
File marks are I<filemark_size> bytes
|
||
|
|
||
|
=head1 EXAMPLES
|
||
|
|
||
|
The following example of the fms.log file specifies that
|
||
|
the tape used during the execution of the B<fms> command had a
|
||
|
capacity of 2,136,604,672 bytes, and that the tape device writes filemarks of
|
||
|
size 1,910,220 bytes.
|
||
|
|
||
|
fms test started
|
||
|
wrote 130408 blocks
|
||
|
Tape capacity is 2136604672 bytes
|
||
|
File marks are 1910220 bytes
