Re: What is op-version?

[ML mail <mlnospam@xxxxxxxxx>]

Thanks Atin for your answer.

I just tried a "gluster v get <volume> cluster.op-version" on my Gluster volume and

Option                                  Value                                  
------                                  -----                                  
cluster.op-version                      30706  

Now I am running GlusterFS 3.7.12 on that server, so shouldn't my op-version be 30712 instead ?

Regards

The above command tells you what op-version the cluster is running with. This version is been owned by GlusterD to manage backward compatibilities and allow clients to use new features. It is very well possible that different peers are running with different gluster version ( I am referring executable version here) but the op-version will be same agreed upon by all the glusterds in the cluster.

To give an example here consider a feature is introduced in n + 1 release, if clients/servers are upgraded to n + 1th bits, you would only be able to use this new feature if the op-version is bumped to n + 1. In an upgrade process op-version is not bumped up automatically.

HTH,
