Description Soumya Koduri 2016-08-25 06:03:46 UTC

Description of problem:

Like many other NFS servers, NFS-Ganesha also should be able to dynamically configure and update export options (like Access Protocols, Client Permissions etc) of an already exported share. The work-around used till now was to unexport and re-export the share with the new options configured. But with upstream NFS-Ganesha 2.4 release we now have that support. This bug is to track those changes and get the required testing done.

Comment 2 Soumya Koduri 2016-08-25 12:11:55 UTC

For our RHGS NFS-Ganesha clustered soluction, we need to make changes in 'refresh-config' functionality to use the new Dbus event provided to update exports dynamically.

Comment 3 Soumya Koduri 2016-10-06 07:14:03 UTC

Patch posted upstream for review - http://review.gluster.org/#/c/15617

downstream patch : https://code.engineering.redhat.com/gerrit/#/c/101283/1

Comment 10 Manisha Saini 2017-04-26 12:32:46 UTC

Verified this RFE with ganesha glusterfs-ganesha-3.8.4-23.el7rhgs.x86_64

Tested following scenarios:

1.Running refresh config while IO's are running on 
2.Change permission of volume in export file from RW to RO while IO's are running and vice versa
3.Change the no_root_squash to root_squash while IO's in process
4.Change client permissions while IO's are running
5.Changing protocol V4 to V3 while IO's are running


As ACL fix is not yet there in the downstream build as updated by Dev,So haven't tested ACL functionality with dynamic refresh config.

Moving this bug to verified state.
