6.5 Removing log files
There is an automated process to clear up log files. However, examine the usage of the system directories
and file systems on each server from time to time. The system directories and file systems are as follows:
• Administration and MDS servers
On these servers, the operating system image is stored on an internal disk that is divided into two
partitions: a partition for the
/
file system and a partition for the
/var
file system.
• The
/var/hpls
file system
This file system is usually mounted by the administration server but can be mounted by the MDS
server. The file system is mounted when the administration service is running. The
/var/hpls
file
system contains the database and event log.
• Object Storage Servers
The Object Storage Server images are network-booted and the
/
file system is a RAM disk image.
The internal disk of the server is also mounted as the
/local
file system. This file system is not seen
when you use the
df
(8) command, but is seen if you explicitly specify
/local
as an argument to the
command.
Table 6-5 lists the various files and directories that you may occasionally need to clean up.
Table 6-5 System directories and file systems
Test Component Version
/var/hpls/evlog/eventlog
This directory contains the system event log. Old records
are cleaned out of the log every day. However, you can
clean out records manually using the
evlogmgr
(8)
command. For example, to delete all events older than 3
days, enter the following command:
# evlogmgr -c ’age < "3d" ’
/var/crash
This directory contains system crash dumps. To clean up
the
/var/crash
directory, delete one of the
subdirectories in the directory.
/var/log/configd
This directory contains the log of the
configd
(8)
daemon. The
configd
(8) daemon compresses log files
that exceed 1MB in size. You can delete these log files
when they are no longer needed.
/var/log/powerd
This directory contains the log of the
powerd
daemon.
The
powerd
daemon only runs on the administration and
MDS Servers. It compresses its log file on a regular basis.
You can delete old compressed log files when they are no
longer needed.
/var/log/hpls_admin
This file contains the start action return codes of the
various services started by the administration service.
Currently, this file is truncated each time the
administration service starts and so does not need to be
cleaned up.
