Hi,
we are currently migrating our ipv4 infrastructure to ipv6, and maybe
later to ipv6 only. This also include our ceph clusters.
My naive approach this is:
1. add a forth (ipv4) mon as safe guard and remove an existing mon
2. set ms_bind_ipv6 to true and add ipv6 networks to public_network
(both in ceph.conf and via ceph config)
3. manually re-add the removed mon with current map and key
4. repeat with other mons and afterwards restart osds and other services
to bind to ipv6, too
The re-added mon in step 3 does not bind to ipv6, only to ipv4. (both
port 3300 and 6789). According to the `ceph tell mon.XYZ config show`
output both the ms_bind_ipv6 and the public_network settings are
recognized by the process.
So the questions are:
- Is dual stack supported for mons? The documentation does not mention
it explicitly...
- Can a mon bind to multiple addresses at all, e.g. one IPv4 and one IPv6?
- How does the mon process decide which address to use?
Best regards,
Burkhard
