You mean when converting a replica 2 volume to a replica 3 volume with arbiter? No, you don't need to do rebalance. What you will need to do instead is monitor heal-info output to ensure the directory tree is sync'd to the arbiter brick. Please refer to http://review.gluster.org/#/c/14502/2 for

So the corruption bug is seen iff your vms are online while fix-layout and/or rebalance is going on. Does that answer your question? The same issue has now been root-caused and there will be a fix for it soon by Raghavendra G. -Krutika On Mon, Apr 3, 2017 at 6:44 PM, Alessandro Briosi

As I understand it, only new files will be sharded, but simply renaming or moving them may be enough in that case. I'm interested in the arbiter/sharding bug you've mentioned. Could you provide any more details or a link? Cheers, D On 30 March 2017 at 20:25, Laura Bailey

Hi I need some advice. I'm currently on 3.8.10 and would like to know the following: 1. If I add an arbiter to an existing volume should I also run a rebalance? 2. If I had sharding enabled would adding the arbiter trigger the corruption bug? 3. What's the procedure to enable sharding on an
