This is a synonyn for required, See section required.
This action tests for the existence of a file or filesystem. It should
be called after all NFS filesystems have been mounted. You may use the
special variable $(binserver) here.
disks:
/filesystem freespace=size-limit define=class-list(,:.)
Files or filesystems which you consider to be essential to the operation of the system can be declared as `required'. Cfengine will warn if such files are not found, or if they look funny.
Suppose you mount your filesystem /usr/local via NFS from some
binary server. You might want to check that this filesystem is not
empty! This might occur if the filesystem was actually not
mounted as expected, but failed for some reason. It is therefore not
enough to check whether the directory /usr/local exists, one must
also check whether it contains anything sensible.
Cfengine uses two variables: sensiblesize and
sensiblecount to figure out whether a file or filesystem is
sensible or not. You can change the default values of these variables
(which are 1000 and 2 respectively) in the control section.
See section control.
If a file is smaller than sensiblesize or does not exist, it
fails the `required' test. If a directory does not exist, or contains
fewer than sensiblecount files, then it also fails the test and a
warning is issued.
disks:
any::
/$(site)/$(binserver)/local
If you set the freespace variable to a value (the default units are kilobytes,
but you may specify bytes or megabytes), e.g.
