butc_logs - Message logs from the Tape Coordinator process
The Backup System Tape Coordinator (
butc) process generates two log
files per device, one for error messages and one for actions.
The
TE_device_name file logs error messages generated by
the Backup System Tape Coordinator that controls the tape device or backup
data file indicated by
device_name.
As the Tape Coordinator initializes, it creates the file in ASCII format in the
/var/lib/openafs/backup directory. If there is an existing file, the
Tape Coordinator renames it to
TE_device_name.old>,
overwriting the existing
TE_device_name.old> file if
it exists.
For a tape device, the Tape Coordinator derives the variable
device_name
portion of the filename from the device pathname listed in the local
/var/lib/openafs/backup/tapeconfig file, by stripping off the initial
"/dev/" string and replacing any other slashes in the name with
underscores. For example, the filename for a device called
/dev/rmt/4m
is
TE_rmt_4m. Similarly, for a backup data file the Tape Coordinator
strips off the initial slash ("/") and replaces any other slashes in
the name with underscores. For example, the filename for a backup data file
called
/var/tmp/FILE is
TE_var_tmp_FILE.
The messages in the file describe the error and warning conditions the Tape
Coordinator encounters as it operates. For instance, a message can list the
volumes that are inaccessible during a dump operation, or warn that the Tape
Coordinator is overwriting a tape or backup data file. The messages also
appear in the
/var/lib/openafs/backup/TL_device_name
file, which traces most of the Tape Coordinator's actions.
The
TL_device_name file logs the actions performed by the
Backup System Tape Coordinator that controls the tape device or backup data
file indicated by
device_name. It also records the same error and
warning messages written to the
TE_device_name file.
As the Tape Coordinator initializes, it creates the file in ASCII format in the
/var/lib/openafs/backup directory. If there is an existing file, the
Tape Coordinator renames it to
TL_device_name.old,
overwriting the existing
TL_device_name.old file if it
exists.
For a tape device, the Tape Coordinator derives the variable
device_name
portion of the filename from the device pathname listed in the local

called

TL_var_tmp_FILE.
