Following is the comment from Sanju:
-------------------------------------
I see that the command is failing if we specify a hostname instead of IPv6:
[root@newhost ~]# gluster --remote-host=myhost.lab.eng.blr.redhat.com volume list
Connection failed. Please check if gluster daemon is operational.
[root@newhost ~]# 

when we add --inet6 option to the cli, it works:
[root@newhost ~]# gluster --remote-host=myhost.lab.eng.blr.redhat.com --inet6 volume list
testrep
[root@newhost ~]#

I believe, this option is added to differentiate whether the given hostname corresponds to IPv4 or IPv6 address.

@Sas, Do you think any changes are needed?

Thanks,
Sanju


-------------------------------

So vdsm-gluster code should try to use '--inet6' when the host uses IPV6 hostnames
Comment 6 SATHEESARAN 2020-07-02 16:25:15 UTC 
Tested with vdsm-4.40.21-1.el8ev.x86_64
On a IPv4 only setup, this check fails and adds '--inet6' to IPv4 hostnames as well, which leads to failure to mount gluster volumes
Comment 7 SATHEESARAN 2020-07-09 07:06:16 UTC 
The dependent vdsm bug is already ON_QA
Comment 8 SATHEESARAN 2020-07-12 14:04:42 UTC 
Tested with vdsm-4.40.22-1.el8ev.x86_64

When using IPV6 FQDN, the additional token for gluster command '--inet6' is used when 
querying for volume information
