Re: gluster volume rebalance making things more unbalanced

Hi Pat,

I checked https://docs.gluster.org/en/latest/Administrator%20Guide/Managing%20Volumes/#rebalancing-volumes and indeed that is possible to affect your performance.

What is your current status ? Did you run a new rebalance ?

Best Regards,
Strahil Nikolov

Hi Strahil


The documentation I looked at:

    * https://docs.google.com/document/d/18iGX6I7I0yHUZ1zAfLIEnXDRPkIoMh6CHmwyyb6J4GM/edit#heading=h.oogvisuwd2qd

suggested that not using force might leave some links behind that could affect performance

Thanks

Pat
