I'd recommend not to use arbiter for tiering irrespective of hot or cold tier. On 05/05/2017 09:42 PM, Walter Deignan wrote: Did that change between 3.9 and 3.10? When I originally saw some references on the Redhat storage packaged solution about a possible incompatibility I assumed it just meant that the hot tier itself couldn't be an arbiter volume. I was tripped up by the change in apparent support for the cold tier between 3.9 and 3.10. But maybe that was just a fixed oversight which never should have worked in the first place? -Walter Deignan -Uline IT, Systems Architect From: Ravishankar N <[email protected]> To: Walter Deignan <[email protected]>, [email protected] Date: 05/05/2017 11:08 AM Subject: Re: [Gluster-users] Arbiter and Hot Tier Hi Walter, Yes, arbiter volumes are currently not supported with tiering. -Ravi On 05/05/2017 08:54 PM, Walter Deignan wrote: I've been googling this to no avail so apologies if this is explained somewhere I missed. Is there a known incompatibility between using arbiters and hot tiering? Experience on 3.9 Original volume - replica 3 arbiter 1 Attach replica 2 arbiter 1 hot tier - failure Attach replica 3 hot tier - success Experience on 3.10 Original volume - replica 3 arbiter 1 Attach replica 2 arbiter 1 hot tier - failure Attach replica 3 hot tier - failure Attach hot tier without specifying replica - success but comes in as a distributed tier which I would assume totally negates the point of having a replicated cold tier? The specific error message I get is "volume attach-tier: failed: Increasing replica count for arbiter volumes is not supported." -Walter Deignan -Uline IT, Systems Architect _______________________________________________ Gluster-users mailing list [email protected] http://lists.gluster.org/mailman/listinfo/gluster-users
