Hi Everyone, I've been fighting with a ceph cluster that we have recently physically relocated and lost 2 OSDs during the ensuing power down and relocation. After powering everything back on we have 3 incomplete 3 remapped+incomplete And indeed we have 2 OSDs that died along the way. The reason I'm contacting the list is that I'm surprised that these PGs are incomplete. We're running Erasure coding with K=4, M=2 which in my understanding we should be able to lose 2 OSDs without an issue. Am I mis-understanding this or does m=2 mean you can lose m-1 OSDs? Also, these two OSDs happened to be in the same server (#3 of 8 total servers). This is an older cluster running Nautilus 14.2.9. Any thoughts? Thanks -Dave
