<font size="2" face="sans-serif">usually, Spectrum Scale comes with a tuned profile (named scale) ..

[root@nsd01 ~]# <br>
</font></tt><br>
<font size="2" face="sans-serif">depending on .... what you need to achieve .. one might be forced to changed that.. e.g. for RoCE .. you need IPv6 to be active ...
</font><br>
<font size="2" face="sans-serif">but for all other scenarios with SpectrumScale (at least what I'm aware of right now) ... IPv6 can be disabled...

Hello,<br>
<br>
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.
<br>
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<br>
<br>
Any comment is welcome<br>
<br>
Cheers,<br>
Heiner<br>

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