[Gluster-devel] Feature proposal for 3.10 release: Support to retrieve maximum supported op-version

[Samikshan Bairagya]

Hi,

Currently there is no way to know the maximum op-version that is 
supported in a heterogeneous cluster. If this is made possible, it would 
prove helpful to users wrt knowing the maximum op-version to which the 
cluster could be bumped up to.

The minimum of the maximum op-versions that is supported by each node 
returns the maximum op-version the cluster can support. The idea is to 
use the gluster volume get interface as follows to retrieve this value:

# gluster volume get all cluster.max-op-version

I feel this could be an useful feature to include in the 3.10 release 
and a related issue [1] is open on Github for the same.

Thanks and Regards,
