The LDM is independent from AWIPS purging, since release 16.2.2 both
/awips2/data_store (which is written by the LMD) and /awips2/edex/data/hdf5
are purged by EDEX itself every hour.

395G for radar is about right for the default retention of 7 days defined
in /awips2/edex/data/utility/common_static/base/purge/radarPurgeRules.xml -
simply change the value defined there and the next purge kickoff will
reread the file (no need to restart EDEX when editing purge rules).
460G is large for /awips2/edex/data/hdf5/grid/, on edex-cloud with about 40
different grids ingesting I store less than 300G. You should take a look
at /awips2/edex/data/utility/common_static/base/purge/gridPurgeRules.xml
and see about trimming some of the retention periods or "versionsToKeep"
for grids you don't use. You can also turn these grids off in pqact.conf
followed by an "ldmadmin pqactHUP".

When disk capacity reaches 100% and EDEX/LDM are running, EDEX purge turns
itself off (really) which obviously does not solve the problem instead it
makes it worse. I need to adjust the default feeds, pattern actions, and
purge rules again to ensure that a 1TB disk does not fill up.
