You could use the du command e.g.

 

# du -csh /var/log/*

 

28% full is pretty normal so I don't think you have anything to worry about.

First step is to find what's using up the space.

If you don't have apps installed, then the main place to look is /var (and maybe /tmp)

 

If you do have apps installed (or have installed other packages yourself), then you need to know where they put their data, and consider moving it off the OS partition to the data volume somehow.  Sometimes that can be done through configuration, sometimes you can do it with soft links.

If you had any run-away log files, you then truncate them (if you want to analyze them later, copy them to the data volume first).

echo > /var/log/logfilename.log
