Ceph pool nearfull Ceph has several parameters to help notify the administrator when OSDs are filling up: # ceph osd dump | grep ratio full_ratio 0.95 backfillfull_ratio 0.9 nearfull_ratio 0.85 By default, when OSDs reach 85% capacity, nearfull_ratio warning is triggered. By default when OSDs reach 90% capacity, backfillfull_ratio warning is triggered.Ceph will print the cluster status.

What do you do when a Ceph OSD is nearfull? I set up a cluster of 4 servers with three disks each; I used a combination of 3TB and 1TB drives which I had laying around at the time. When I ran ceph osd status, I see that one of the 1TB OSD is nearfull which isn't right. You never want to have an OSD fill up 100%. So I need to make some changes.DESCRIPTION. ceph is a control utility which is used for manual deployment and maintenance of a Ceph cluster. It provides a diverse set of commands that allows deployment of monitors, OSDs, placement groups, MDS and overall maintenance, administration of the cluster.Further diagnosis hinted that the data pool had many orphan objects, that is objects for inodes we could not locate in the live CephFS. All the time, we did not notice any significant growth of the metadata pool (SSD-based) nor obvious errors in the Ceph logs (Ceph, MDS, OSDs). Except for the fill levels, the cluster was healthy. Restarting Pools are logical partitions for storing objects. When you first deploy a cluster without creating a pool, Ceph uses the default pools for storing data. A pool provides you with: Resilience: You can set how many OSD are allowed to fail without losing data. For replicated pools, it is the desired number of copies/replicas of an object. ceph学习资料整理.
