FMS.LOG(5) AFS File Reference FMS.LOG(5)NAMEfms.log - Records output from the fms command
DESCRIPTION
The fms.log file records the output generated by the fms command. The
output includes two numbers that can appear in a tape device's entry in
the /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 as filemarks) that the tape device writes.
When transferring the numbers recorded in this file to the tapeconfig
file, adjust them as specified in tapeconfig(5), to improve Tape
Coordinator performance during dump operations.
If the fms.log file does not already exist in the current working
directory, the fms command interpreter creates it. In this case, the
directory's mode bits must grant the "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 w permission to the issuer of the fms command. The 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 cat command. By default, the mode bits on the fms.log file
grant the required "r" permission only to the owner (which is the local
superuser "root" by default).
OUTPUT
The first few lines of the file provide a simple trace of the 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 <tape_size> bytes
File marks are <filemark_size> bytes
EXAMPLES
The following example of the fms.log file specifies that the tape used
during the execution of the fms command had a capacity of 2,136,604,672
bytes, and that the tape device writes filemarks of size 1,910,220
bytes.
