Need some #Ceph advisory for my private cluster on #proxmox:
3 nodes with 2x 18 TB HDD each.
According to some docs I found, WAL/DB size should be 1-4% of the disk size, so a SSD should be between 180 to 720 GB for each disk or 360 to 1.44 TB for the two disks in each node.
Is this still be true or is it nowadays more relaxed and - let's say - 200 GB for each HDD will be sufficient?
