In the example you provided…
...
filter = [ "a|/dev/vd.*|", "a|/dev/drbd*|", "r|.*|" ]
write_cache_state = 0
volume_list = [ "rootvg", "vg1", "vg2" ]
...
…it looks like you are accepting anything that begins with '/dev/vd.' or '/dev/drbd' and rejecting everything else. Sorry for my dumb question, but if the goal is to filter out certain devices so LVM won't grab them before drbd does, wouldn't you want to reject them instead of accepting them?
Here is what I have written on my system...
...
filter = [ "a|/dev/sda*|", "a|/dev/drbd*|", "r|.*|" ]
write_cache_state = 0
volume_list = [ "vg00", "vg_drbd0", "vg_drbd1" ]
...
I have not rebooted yet because I am not sure this is correct.
