o Filter which caches valid devices in a file. Pass in init == 1 to the constructor if you want it to ignore the existing cache and check every device again (eg, vgscan, pvscan).

#ifndef _LVM_FILTER_PERSISTENT_H
o composite filter that allows us to merge filters. Think of it as &&'ing filters in order. eg, f = composite_filter_create(2, regex_filter, persistent_filter); ownership of the filters passes, they will be destroyed when f's destroy method is called.

int persistent_filter_load(struct dev_filter *f, struct config_tree **cft_out);
Currently if clvmd is running and user issues vgscan, the device cache file is dumped both in vgscan and clvmd process. Unfortunately, clvmd calls lvmcache_label_scan, it properly destroys persistent filter, but during persistent_filter_dump it merges old cache content back! This causes that change in filters is not properly propagated into device cache after vgscan on cluster. (Only new devices are added.) https://bugzilla.redhat.com/show_bug.cgi?id=591861
