Hallo Heiner,
usually, Spectrum Scale comes with a tuned profile (named scale) ..
[root@nsd01 ~]# tuned-adm active
Current active profile: scale
in there
[root@nsd01 ~]# cat /etc/tuned/scale/tuned.conf | tail -3
# Disable IPv6
net.ipv6.conf.all.disable_ipv6=1
net.ipv6.conf.default.disable_ipv6=1
[root@nsd01 ~]#
depending on .... what you need to achieve .. one might be forced to changed that.. e.g. for RoCE .. you need IPv6 to be active ...
but for all other scenarios with SpectrumScale (at least what I'm aware of right now) ... IPv6 can be disabled...

Hello,
I just noted that our ganesha daemons offer IPv6 sockets only, IPv4 traffic gets encapsulated. But all traffic to samba is IPv4, smbd offers both IPv4 and IPv6 sockets.
I just wonder whether this is to be expected? Protocols support IPv4 only, so why running on IPv6 sockets only for ganesha? Did we configure something wrong and should completely disable IPv6 on the kernel level
Any comment is welcome
Cheers,
Heiner

I did check with
ss -l -t -4
ss -l -t -6
add -p to get the process name, too.
do you get the same results on your ces nodes?
