Hi Ceph-Users, I'm working with a Ceph cluster (about 50TB, 28 OSDs, all Bluestore on lvm). Recently, I'm trying to use the Erasure Code pool. My question is "what's the best practice for using EC pools ?". More specifically, which plugin (jerasure, isa, lrc, shec or clay) should I adopt, and how to choose the combinations of (k,m) (e.g. (k=3,m=2), (k=6,m=3) ). Does anyone share some experience? Thanks for any help. Regards, David |
