缩小副本数
[SOLVED] – change num-replicas on ceph rool online? | Proxmox Support Forum
ceph osd pool set POOL_NAME size 3 ceph osd pool set POOL_NAME min_size 2 // 缩小到 1 个副本 # ceph config set global mon_allow_pool_size_one true # ceph osd pool set data_pool min_size 1 # ceph osd pool set data_pool size 1 --yes-i-really-mean-it
允许删除：
# ceph config set global mon_allow_pool_delete true # ceph osd pool delete 'pool name' 'pool name' --yes-i-really-really-mean-it
