Its primary function is to try to keep running all instances which are marked as up in the configuration file, by trying to start them a limited number of times. Its other function is to repair DRBD links by reactivating the block devices of instances which have secondaries on nodes that have been rebooted. The watcher does synchronous queries but will submit jobs for executing the changes. Due to locking, it could be that the jobs execute much later than the watcher executes them. The command has a state file located at @LOCALSTATEDIR@/lib/ganeti/watcher.data and a log file at @LOCALSTATEDIR@/log/ganeti/watcher.log. Removal of either file will not affect correct operation; the removal of the state file will just cause the restart counters for the instances to reset to zero. &footer;
