As for accessing block devices, you can limit accesses to those
devices by filter option in lvm.conf. This is an example which
allows accesses only to /dev/sd*
filter = [ "a|/dev/sd|", "r|.*|" ]
You can specify more strict rule like
filter = [ "a|/dev/sd[a-z]|", "r|.*|" ]
What if I don't want ANY devices to be scanned every time an lvm command
is run? Shouldn't they be scanned once when udev first detects they
have been attached, and no more? I thought removing /dev from the scan=
line would do that, but it didn't.
I'd have say - this is work-in-progress for now - yes, udev should handle all
this for lvm - but we are not yet there...
Meanwhile - you may write few scripts which will pass exact filters for your
lvm commands if you know you do not need to touch those devices.
