Hi, As you have mentioned client/server version in thread it shows package version are different on both(client,server). We would recommend you to upgrade both servers and clients to rhs-3.10.1. If it is not possible to upgrade both(client,server) then in this case it is required to upgrade

Since things are in production making upgrades needs to be scheduled so this may take a while before I can get everything up to 3.10. I have set the write-behind option to off on the servers but do I need to restart the servers or can I just get away with umount/mount the clients? Thank you

Thanks Amar, I’ll consider your recommendations. But why performance is totally different on two nodes? Will data be written to both nodes at the same time? From: Amar Tumballi Sent: Friday, March 31, 2017 3:14 PM To: Alvin Starr Cc:

Hi Yong, Gluster uses the openssl library, which supports SSL 3.0 and TLS versions 1.0,1.1,1.2. I actually don't know if its dynamically linked against the openssl library nor what version of the openssl lib gluster has been tested with. That is important info to know that is currently

Hi Alvin, Thanks for the dump output. It helped a bit. For now, recommend turning off open-behind and read-ahead performance translators for you to get rid of this situation, As I noticed hung FLUSH operations from these translators. -Amar On Wed, Mar 29, 2017 at 6:56 AM, Alvin Starr

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
