WebCeph is designed for fault tolerance, which means Ceph can operate in a degraded state without losing data. Ceph can still operate even if a data storage drive fails. The degraded state means the extra copies of the data stored on other OSDs will backfill automatically to other OSDs in the storage cluster. When an OSD gets marked down this can mean the … WebThe question is for home should I bother trying store the db, wal, journal and/or metadata for the HDD's on the SSD's, or does it overly complicate things, from the HDD pool I would like 250MB/sec on reads, 250MB/sec writes would be nice to have. For all I know, my CPU's (Intel J4115 Quad-core) could be the bottleneck. Thanks. Richard
