NAME

       ganeti-watcher - ganeti cluster watcher

SYNOPSIS

       ganeti-watcher

DESCRIPTION

       The  ganeti-watcher  is  a periodically run script which is responsible
       for keeping the instances in the correct status.

       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.

       In order to prevent piling up commands, all the gnt-* commands executed
       by ganeti-watcher are run with a timeout of 15 seconds.

       The  command  has  a state file located at /var/lib/ganeti/watcher.data
       and a log file at /var/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.
