These unit files initiate a zpool scrub on a regular basis (weekly or monthly). For one-off scrubs
you should simply use zpool scrub tank, where tank is the pool to be scrubbed.
See zpool(8) for documentation of zpool subcommands.
Note that some time ago zfsutils started packaging a cron job in /etc/cron.d/zfsutils-linux, which simply scrubs all pools on every 2nd Sunday of the month. So you might not actually need this separate unit anymore, unless you want finer granularity or just prefer to use a systemd timer.
The only option to these timers is the pool name to be scrubbed. If your pool name is mypool and
you want to schedule weekly scrubs use
systemctl enable --now [email protected]
After cloning the repository or downloading and extracting a release use make install to install
the unit files in /etc/systemd/system.
Afterwards reload your daemon with systemd daemon-reload and enable the desired timer (see
USAGE).
Clone the repository:
cd /tmp
git clone https://github.com/ansemjo/systemd-zpool-scrub-timers.git
cd systemd-zpool-scrub-timers/
Install unit files:
sudo make install
Enable timer:
sudo systemctl enable --now [email protected]
