Subject: [PVE-User] 2 host cluster, direct link: best configuration?
Date: Fri, 18 Feb 2022 18:55:18 +0100 [thread overview]
Message-ID: <4535ei-8j11.ln1@hermione.lilliput.linux.it> (raw)
We have to setup a little 2 node cluster, with symmetrical nodes, using
replication.
For that, we have added a 10G interface, and setup a direct link between the
two server.
But how is better to setup the link? Some ideas:
1) another network, different from LAN
pro: simple
cons: replica happen only on cluster/corosync interface? So i have to
setup corosync on direct link addresses?
2) ip override; eg LAN interfaces are 10.37.5.21/21 and 10.37.5.22/21;
direct link interfaces are 10.37.5.21/32 and 10.37.5.22/32, and an
explicitly route to other host
pro: if direct link go down, we can simple tear down interfaces
cons: no auto, interfaces have to tear down manually
3) setup a bridge around LAN and direct link cable, setup STP and leave the
switches all the work.
This config suggested, more or less, by:

Thanks.
