[Gluster-users] add-brick and fix-layout takes some VMs offline
Hi there, We have a distributed-replicated volume hosting KVM guests running Gluster 3.4.1. We've grown from 1 x 2 -> 2 x 2 -> 3 x 2,but each time we've added nodes or run a fix layout, some of our guests go offline (or worse with error=continue they silently error). After the last addition we didn't even run fix-layout as the guests are becoming increasingly important. Those guests are currently are using a combination of FUSE and libgfapi. Is there a setting or group of settings we should use to ameliorate this problem? Is FUSE or libgfapi more forgiving when add-brick or fix-layout is run? Any info is greatly appreciated. Thanks.
