lvm.conf – initramfs

centos uses:

dracut -f

After updating /etc/lvm.conf, it’s necessary to update the initrd so that this file will be copied there, where the filter matters the most, during boot. Perform:

update-initramfs -u -k all

Every time either /etc/lvm.conf or /etc/multipath.conf is updated, the initrd should be rebuilt to reflect these changes. This is imperative when blacklists and filters are necessary to maintain a stable storage configuration.
