Indeed, I am referring to the RedHat Package Manager. Quite simply put, if 
/var/lib/rpm is on GlusterFS, any attempt to use rpm fails. I tried various 
flags in DB_CONFIG in /var/lib/rpm that should have, in theory, disabled mmap 
usage, but they made no difference, all rpm operations would fail even before 
rpm finished creating it's /var/lib/rpm/__* lock files.

The way I worked around it is by converting the RPM database to use SQLite (DB 
API 4 (SQLite) instead of 3 (BerkeleyDB), IIRC). This seems to work OK, but the 
fact that Mozilla's use of SQLite seems to be unreliable on GlusterFS concerns 
me.
