Re: [Gluster-users] Floating IPv6 in a cluster (as NFS-Ganesha VIP)

2017-06-01 Thread Jan 
Hi all,

thank you very much for support! I filed the bug:
https://bugzilla.redhat.com/show_bug.cgi?id=1457724

I'll try to test it again to get some errors / warnings from log.

Best regards,

Jan

/usr/lib/ocf/resource.d/heartbeat/IPaddr2 does support IPv6:

  ...
  Manages virtual IPv4 and IPv6 addresses (Linux
specific version)

  
  
  
  The IPv4 (dotted quad notation) or IPv6 address (colon hexadecimal
notation)
  example IPv4 "192.168.1.1".
  example IPv6 "2001:db8:DC28:0:0:FC57:D4C8:1FFF".
  
  ...


If it's not working I suspect the ganesha-ha.sh script may not handle
IPv6 addrs from the ganesha-ha.conf correctly.

Please file a bug at
https://bugzilla.redhat.com/enter_bug.cgi?product=GlusterFS component:
common-ha, version: 3.10.

Patches are nice too. ;-)

Thanks

great work!

The only thing that I miss is IPv6 support. I know that there are some
challenges and that’s OK. For me it’s not important whether Gluster
servers use IPv4 or IPv6 to speak each other and replicate data.

The only thing that I’d like to have is a floating IPv6 for clients when
I use Ganesha (just IPv6, dual stack isn’t needed).

I tested it and I put IPv6 into ganesha-ha.conf instead of IPv4 and it
didn’t work. But I think that it might work since Ganesha supports IPv6:

netstat -plnt

tcp6   00 :::2049:::*  LISTEN  1856/ganesha.nfsd

Is there a way how to do that? Maybe build a cluster with IPv4 and then
change “something” in Pacemaker / Corosync and replace IPv4 by IPv6?



At-least from [1] looks like it is supported. Do you see any 
errors/warnings in the log files? (/var/log/messages, 
/var/log/pacemaker.log, /var/log/corosync.log)

Thank you.

[Gluster-users] Floating IPv6 in a cluster (as NFS-Ganesha VIP)

great work!
