I have an 8-node cluster with old hardware. a week ago 4 nodes went down and the CEPH cluster went nuts. All pgs became unknown and montors took too long to be in sync. So i reduced the number of mons to one and mgrs to one as well Now the recovery starts with 100% unknown pgs and then pgs start to move ot inactive . It generally fails to recover in the middle and starts from scratch. It's hold hardware and OSDs have lots of slow ops and probably number of bad sectors as well Any suggestions on how to tackle this. It's a nautilus cluster and pretty old (8-year old hardware) Thanks
