NAME¶
rebootmgrd, rebootmgr.service - Reboot the machine during a
maintenance window.
SYNOPSIS¶
/usr/libexec/rebootmgrd [--debug | --verbose | --help |
--version]
/usr/lib/systemd/system/rebootmgr.service
DESCRIPTION¶
To avoid that a whole cluster or a set of machines with the same
task reboot at the same time, rebootmgrd reboots the machine
following configured policies.
Reboot Strategies¶
rebootmgr supports various strategies for determining when a
reboot should be performed:
instantly
The reboot is carried out without waiting for a
maintenance window.
maint-window
Reboot only during a specific maintenance window. If no
maintenance window is specified, the system reboots immediately.
best-effort
This is the default setting. If a maintenance window is
specified, maint-window is used. If no maintenance window is specified,
the reboot takes place immediately (instantly).
off
rebootmgr continues to run, but ignores all reboot timers
that expire in the meantime. The configuration file is not updated, so this
option is no longer active after a reboot. When rebootmgr is reactivated, it
will continue to use the old specified maintenance window and any reboot
timers that are still running will no longer be ignored.
on
Reboots will be enabled again. Existing reboot timers
will be executed again. Elapsed timers will not be restarted.
The reboot strategy can be configured via rebootmgr.conf(5)
and adjusted at runtime via rebootmgrctl(1). These changes will be
written to the configuration file and survive the next reboot. Except for
the off strategy.
OPTIONS¶
--debug
Log additional informations during runtime. A real reboot
is not done in debug mode.
--verbose
Log additional informations about requested
reboots.
--help
Display help text and exit
--version
Output version information and exit
