|
|
|
The F<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 F</usr/afs/backup/tapeconfig> file on the Tape
|
|
|
|
Coordinator machine to which the tape device is attached:

The capacity in bytes of the tape in the device.

|
The size in bytes of the end-of-file (EOF) marks (often referred to simply
|
2005-12-14 01:30:20 +00:00
|
|
|
as I<filemarks>) that the tape device writes.

|
|
When transferring the numbers recorded in this file to the F<tapeconfig>
|
|
|
|
file, adjust them as specified in L<tapeconfig(5)>, to improve Tape
|
|
|
|
Coordinator performance during dump operations.
|
|
|
|
|
|
|
|
If the F<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 C<rwx> (read, write, and 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 F<fms.log> file grant the
|
|
|
|
required C<r> permission only to the owner (which is the local superuser
|
|
|
|
C<root> by default).

=head1 OUTPUT
|
|
|
|
|
2005-12-14 01:30:20 +00:00
|
|
|
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:
|
2005-12-08 12:14:33 +00:00
|
|
|
|
2005-12-14 01:30:20 +00:00
|
|
|
Tape capacity is <tape_size> bytes
|
|
|
|
File marks are <filemark_size> bytes

|
|
|
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.
