Hi, I can't use bcache devices as members of lvm volume groups because dmsetup can't find the devices. It provides the ever useful feedback of: # pvcreate /dev/bcache0 Device /dev/bcache0 not found (or ignored by filtering). My LVM.conf is only filtering out nbd devices: filter = [ "r|/dev/nbd.*|", "a/.*/" ] Any insight would be greatly appreciated. :) I also noted that bcache devices don't appear in iostat..
