Hi Y'all, We have a new ceph cluster online that looks like this: md-01 : monitor, manager, mds md-02 : monitor, manager, mds md-03 : monitor, manager store-01 : twenty 30TB NVMe OSDs store-02 : twenty 30TB NVMe OSDs The cephfs storage is using erasure coding at 4:2. The crush domain is set to "osd". (I know that's not optimal but let me get to that in a minute) We have a current regular single NFS server (nfs-01) with the same storage as the OSD servers above (twenty 30TB NVME disks). We want to wipe the NFS server and integrate it into the above ceph cluster as "store-03". When we do that, we would then have three OSD servers. We would then switch the crush domain to "host". My question is this: Given that we have 4:2 erasure coding, would the data rebalance evenly across the three OSD servers after we add store-03 such that if a single OSD server went down, the other two would be enough to keep the system online? Like, with 4:2 erasure coding, would 2 shards go on store-01, then 2 shards on store-02, and then 2 shards on store-03? Is that how I understand it? Thanks for any insight! -erich
