You're right, filters are difficult to understand and use correctly. The complexity and confusion in the code is no better. With the removal of lvmetad in 2.03 versions (e.g. RHEL8) there's no difference between filter and global_filter, so that's some small improvement. But, I think filters should be replaced or overhauled with something easier to use and more useful at a technical level. I've created a bz about that and welcome thoughts about what a replacement should or should not be like. With input the work is more likely to be prioritized. https://bugzilla.redhat.com/show_bug.cgi?id=1803266 _______________________________________________ linux-lvm mailing list linux-lvm@redhat.com https://www.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
