Hi CephFS experts, >From document, I know multi-fs within a cluster is still experiment feature. 1. Is there any estimation about stability and performance for this feature? 2. It seems that each FS will consume at least 1 active MDS and different FS can't share MDS. Suppose I want to create 10 FS , I need at least 10 MDS. Is it right? Is ther any limit number for MDS within a cluster? Thanks, Marvin Zhang
