Hybrid bluegill identification
Now the virtual disks are all running normal 2-way mirror, but two of the virtual disks are degraded. This is probably because one of the physical disks was offline for a short period of time. However, now the virtual disk cannot be repaired, even though, all physical disks are healthy. There is plenty of available space in the storage pool.
I meet text "mds cluster is degraded". I try to seek it at official Ceph docs, but nothing find. If I understand correctly, MDS needed for mounting and presenting ceph's data as regular FS. Can someone talk about conditions of appearance for this type of error?
