  • A ceph pool ensures data availability by creating a number of object copies. At the time of pool creation, we can define the replica size. The default replica size is 2(object + additional copy). When we first deploy a ceph cluster without creating a pool,ceph uses default pools to store data. A ceph pool supports snapshot features.

Jul 03, 2018 · 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%.
