DRBDLinks

Introduction

A program to manage making and restoring links in a Linux HA cluster using DRBD. When the shared cluster drive is mounted, certain files and directories are moved aside and links are created into the shared partition. The list of files and directories which are linked is controlled by a configuration file, for example:

mountpoint('/shared')
link('/home/')
link('/etc/httpd')
link('/var/log/httpd', '/shared/logs/httpd')

In this example, we are mounting the DRBD partition in "/shared", and by default we are causing "/home" to be linked to "/shared/home", "/etc/httpd" to "/shared/etc/httpd", etc... The last line shows an example of a link which specifies the destination location explicitly, instead of assuming that it goes to the same location under shared.

================================
Version 1.12 -- Thu Sep 04, 2008

Added OPTIONS and EXAMPLES sections in the man page (Mike Loseke)
Log debugging information via syslog.
Added "cleanthisconfig" config command.  This is meant to be used in a
      system with multiple drbd mountpoints, started at different times.
      Each one would typically have it's own config file, which may not be
      available at system boot.  drbdlinks will now copy these files off to a
      safe location when it starts, and drbdlinksclean will run any of these
      it finds in addition to the normal drbdlinks.conf.
Adding a "/var/run/drbdlinks/configs-to-clean" directory, any config files
      that are in there will get cleaned by "drbdlinksclean" at system boot.
Modified monitor option so that it returns "stopped" instead of
      "not configured" if there is no configuration file.  Required for the
[...]
