Description Saurabh 2015-06-25 09:52:06 UTC

Description of problem:
Usually if you use "showmount <server hostname or iptaddr>" command then it displays the IPs of clients that have mounted the exports from the server. 

Now, in case of nfs-ganesha, we have to use the vipaddr and the showmount <vipaddr> does not display the client that have mounted the volume.

It is an important funcationality for sysadmin to figure out where all the server is mounted.

Version-Release number of selected component (if applicable):
glusterfs-3.7.1-5.el6rhs.x86_64
nfs-ganesha-2.2.0-3.el6rhs.x86_64

How reproducible:
always

Steps to Reproduce:
1. create a volume of 6x2 type, start it
2. confifure nfs-ganesha
3. mount the volume on a client
4. showmount <vipaddr>

Actual results:
result of step4,
[root@nfs11 ~]# showmount 10.70.44.92
Hosts on 10.70.44.92:


no client displayed, even though volume is mounted.

Expected results:
client IP should be displayed in case exports are mounted from the server.
such as, 

[root@nfs11 ~]# showmount rhsqe-repo.lab.eng.blr.redhat.com
Hosts on rhsqe-repo.lab.eng.blr.redhat.com:
10.70.42.123

This is not a critical functionality, deferring to rhgs-3.2.

Comment 6 Niels de Vos 2016-06-20 11:45:52 UTC

The feature requested was added to Gluster/NFS with http://review.gluster.org/4430 . Keeping track of clients that mount a certain export is best effort, and can not be relied on in any case.

This is currently a low-priority RFE, we are not planning to implement this.
