I get much better performance out of the gfapi - seeing around 30-40% better reads and IOPs over the fuse client in VM's. -- Lindsay ___ Gluster-users mailing list Gluster-users@gluster.org http://www.gluster.org/mailman/listinfo/gluster-users
Re: [Gluster-users] add/replace brick corrupting data
That should be an important clue. That being said, when we lose a brick, we've traditionally just live migrated those VMs off onto other clusters because we didn't want to take the heal hit which at best slowed down our VMs at on the pickier ones cause them to RO out. We have not yet upgraded to 3.7.x yet (still on 3.4 cuz it aint broke) and are hoping that sharding solves that problem. But it seems everytime it looks like things are 'safe' for 3.7.x, something comes up. Fortunately, we like the fuse mount so maybe we are still ok. -wk On 5/16/2016 4:42 AM, Lindsay Mathieson wrote: Ok, this is probably an interesting data point.

Ok, this is probably an interesting data point. I was unable to reproduce the problem when using the fuse mount. Its late here so I might not have time to repeat with the gfapi, but I will tomorrow.
