HDAPSD(8) hdapsd HDAPSD(8)NAME
hdapsd - park the drive in case of an emergency
SYNOPSIS
hdapsd [-f|-d <device>|-s <sensitivity>|-a|-v|-b|-p|-t|-y|-l|-V|-h]
OPTIONS -d --device=<device>
<device> is likely to be hda or sda. Can be given multiple times to protect multiple devices.
-f --force
Force unloading heads, even if kernel thinks different (on pre ATA7 drives). This only works when adding devices by hand (-d).
-s --sensitivity=<sensitivity>
How sensitive hdapsd should be to movements. Defaults to 15, higher values mean less sensitive.
-a --adaptive
Adaptive threshold (automatic increase when the built-in keyboard/mouse are used).
-v --verbose
Get verbose statistics.
-b --background
Run the process in the background.
-p --pidfile[=<pidfile>]
Create a pid file when running in background. If <pidfile> is not specified, it's set to /var/run/hdapsd.pid.
-t --dry-run
Don't actually park the drive.
-y --poll-sysfs
Force use of sysfs interface to accelerometer.
-l --syslog
Log to syslog instead of stdout/stderr.
-V --version
Display version information and exit.
-h --help
Display help and exit.
You can send SIGUSR1 to deactivate hdapsd for 8 seconds.

keepalived - load-balancing and high-availability service
SYNOPSIS
keepalived [-f|--use-file=FILE] [-P|--vrrp] [-C|--check] [-l|--log-console] [-D|--log-detail] [-S|--log-facility={0-7}]
[-V|--dont-release-vrrp] [-I|--dont-release-ipvs] [-R|--dont-respawn] [-n|--dont-fork] [-d|--dump-conf] [-p|--pid=FILE]
[-r|--vrrp_pid=FILE] [-c|--checkers_pid=FILE] [-v|--version] [-h|--help]
DESCRIPTION
Keepalived provides simple and robust facilities for load-balancing and high-availability. The load-balancing framework relies on
well-known and widely used Linux Virtual Server (IPVS) kernel module providing Layer4 load-balancing. Keepalived implements a set of
checkers to dynamically and adaptively maintain and manage load-balanced server pool according their health. Keepalived also implements the
VRRPv2 protocol to achieve high-availability with director failover.
OPTIONS -f, --use-file=FILE
Use the specified configuration file. The default configuration file is "/etc/keepalived/keepalived.conf".
-P, --vrrp
Only run the VRRP subsystem. This is useful for configurations that do not use IPVS load balancer.
-C, --check
Only run the healthcheck subsystem. This is useful for configurations that use the IPVS load balancer with a single director with no
failover.
-l, --log-console
Log messages to the local console. The default behavior is to log messages to syslog.
-D, --log-detail
Detailed log messages.
-S, --log-facility=[0-7]
Set syslog facility to LOG_LOCAL[0-7]. The default syslog facility is LOG_DAEMON.
-V, --dont-release-vrrp
Don't remove VRRP VIPs and VROUTEs on daemon stop. The default behavior is to remove all VIPs and VROUTEs when keepalived exits
-I, --dont-release-ipvs
Don't remove IPVS topology on daemon stop. The default behavior it to remove all entries from the IPVS virtual server table on when
keepalived exits.
-R, --dont-respawn
Don't respawn child processes. The default behavior is to restart the VRRP and checker processes if either process exits.
-n, --dont-fork
Don't fork the daemon process. This option will cause keepalived to run in the foreground.
-d, --dump-conf
Dump the configuration data.
-p, --pid=FILE
Use specified pidfile for parent keepalived process. The default pidfile for keepalived is "/var/run/keepalived.pid".
-r, --vrrp_pid=FILE
Use specified pidfile for VRRP child process. The default pidfile for the VRRP child process is "/var/run/keepalived_vrrp.pid".
-c, --checkers_pid=FILE
Use specified pidfile for checkers child process. The default pidfile for the checker child process is
"/var/run/keepalived_checkers.pid".
-v, --version
Display the version and exit.
-h, --help
Display this help message and exit.
