No, it's redundant to use carpdev in this case, but it doesn't matter.
Do you see the traffic incoming on both machines?
Maybe the link2 mode works better for you...
hi ah ok i will try this , and yes there ist traffic on both machines but not
from all clients ( 50% can reach there default gw and rest don4t )
but we check our switches ( HP 2824 ) and my networker says that we have old
revision of firmware inside.
we will update this at monday and that we test it again.
is the link2 option an replacement for link1 ?

Quoting from carp(4):
Please note that activating stealth mode on a carp interface that has
al-
ready been running might not work instantly. As a workaround the VHID
can be changed to a previously unused one, or just wait until the MAC
table entry in the switch times out.
Some Layer-3 switches do port learning based on ARP packets. Therefore
the stealth mode cannot hide the virtual MAC address from these kind of
devices. In such cases, carp can be told to use a multicast MAC address
by additionally enabling the link2 flag.
