The ability to bind to multiple ports has paved the way for dual-stack
IPv4 and IPv6 support. That said, dual-stack operation is not yet
supported as of Quincy v17.2.0."
just the quick questions:
Is a dual stacked networking with IPv4 and IPv6 now supported or not?
From which version on is it considered stable?
IIIRC, the "enable dual" stack PR's were more or less "accidentally"
merged, at least that's what Radoslaw Zarzynski (added to CC) told me
during the developer summit at Cephalocon in Amsterdam. There was a
discussion about dual stack support after that. I voted in favor of not
supporting dual stack. Currently there are no IPv6 (only) tests that are
performed, it's IPv4 only. Let alone dual stack testing setups. It gets
complicated quickly if you want to test all sort of combinations (some
daemons with dual stack, some IPv4 only, some IPv6 only, etc.).
Are OSDs now able to register themselves with two IP addresses in the
cluster map? MONs too?
At least the OSDs and MDSs can, and caused trouble for kernels with
messenger v2 support. We had to disable IPv4 explicitly to get rid of
the IPv4 "0.0.0.0" addresses in the MDS map. See this thread .
