Description Kaushal 2013-09-04 12:35:54 UTC

+++ This bug was initially created as a clone of Bug #1002871 +++

Describe the issue: 
===================

When Servers are in higher version than client the volume set operation fails, this was observed when the servers were in bigbend(3.4.0) base and client was in anshi(3.3.0) base. In field customers can have both 3.4.0 and 3.3.0 client accessing the same RHS servers(3.4.0)


Server: glusterfs-server-3.4.0.24rhs-1.el6rhs.x86_64 and 
client: glusterfs-3.3.0.11rhs-1.el6.x86_64

Try to set any volume option, it fails with below message. 

[root@rhs-client11 ~]# gluster volume set help | grep client-log
Option: diagnostics.client-log-level
[root@rhs-client11 ~]# gluster volume set vol-dr client-log-level DEBUG
volume set: failed: One or more connected clients cannot support the feature being set. These clients need to be upgraded or disconnected before running this command again
[root@rhs-client11 ~]# 
[root@rhs-client11 ~]# gluster volume set vol-dr cluster.metadata-self-heal off
volume set: failed: One or more connected clients cannot support the feature being set. These clients need to be upgraded or disconnected before running this command again
[root@rhs-client11 ~]# gluster volume set vol-dr cluster.data-self-heal off
volume set: failed: One or more connected clients cannot support the feature being set. These clients need to be upgraded or disconnected before running this command again
[root@rhs-client11 ~]# 
[root@rhs-client11 ~]# gluster volume set vol-dr cluster.entry-self-heal off
volume set: failed: One or more connected clients cannot support the feature being set. These clients need to be upgraded or disconnected before running this command again
[root@rhs-client11 ~]# 

The above behaviour needs to be documented.

Amar,

Kindly review and sign-off the following known issue:

Issue: When Red Hat Storage Servers are of higher version and one of the client is of glusterfs-3.3.0.11rhs-1.el6.x86_64 or older version, the Volume Set operation fails.

Work Around: Upgrade your client to the latest version and ensure that all the clients are of same version.

Also, let me know if I have to clone this bug to create an eng bug? 

Thanks,
Divya

    glusterd: Fix connected clients check during 'volume set'
    
    Use the volume's newly calulatedclient-op-version for the connected
    clients check. This prevents rejection of server options of higher
    op-version when clients of lower op-version are connected. Also,
    initialize the variables of the newly calculated volume op-version and
    client-op-version with the current values, instead of the cluster
    op-version.
