fstrimDaemon

Very lightweight daemon executing fstrim every few hours.

MOTIVATION:

Usually fstrim is run from cron but cron can execute command only at particular time. If you turn off your computer you can miss it. This daemon solves this problem running fstrim in the loop. It gives also very low priority to this task in order not to intrude your main activities.

INSTALLATION

Run as root:

./install.sh

To start daemon if you are using init.d:

/etc/init.d/fstrimDaemon start

To start daemon if you are using systemd:

systemctl start fstrimDaemon

### To start daemon automatically at each boot if you are using systemd:

systemctl enable fstrimDaemon

### To stop daemon if you are using init.d:

/etc/init.d/fstrimDaemon stop

### To uninstall run as root:

./uninstall.sh

If you are using systemd, uninstall.sh will stop and disable the daemon

Files which are not removed during uninstallation:
- _/etc/conf.d/fstrimDaemon_
- _/var/log/fstrimDaemon.log_


CONFIGURATION
-----------------------------------------


Default config file: _/etc/conf.d/fstrimDaemon_

```bash
# Time to wait after daemon start to perform first fstrim
# e.g. "30m" - 30 minutes. See man sleep.
SLEEP_AT_START="2h"

# Time to sleep between next repetition of fstrim
# e.g. "5d" - 5 days. See man sleep.
SLEEP_BEFORE_REPEAT="3h"

# Maximum CPU Load when fstrim is allowed.
# If current CPU Load is above daemon sleeps for 5 min.
# 1.0 means all cores are busy.
MAX_CPU_LOAD="0.2"

# integer [-20 .. 19 ] default 0
# change the priority of the server -20 (high) to 19 (low)
# see nice(1) for description
NICE="19"

# See start-stop-daemon(8) for possible settings
# Modifies the IO scheduling priority of the daemon.  Class
# can be 0 for none, 1 for real time, 2 for best effort and 3
# for idle.  Data can be from 0 to 7 inclusive.
IONICE="3"

# Here Daemon's process id will be stored
PID="/var/run/fstrimDaemon.pid"

# Here Daemon logs
LOG="/var/log/fstrimeDaemon.log"

# The main daemon script i.e. fstrim-sleep loop
DAEMON="/usr/sbin/fstrimDaemon.sh"
