I have a 4 node ceph cluster, but the disks are not equally distributed across all machines (they are substantially different from each other)
One machine has 12 x 1TB SAS drives (h1), another has 8 x 300GB SAS (s3) and two machines have only two 1 TB drives each (s2 & s1). Now machine s3 has by far the most CPU's and RAM, so I'm running my VM's mostly from there, but I want to make sure that the writes that happen to the ceph cluster get written to the "local" osd's on s3 first and then the additional writes/copies get done to the network. Is this possible with ceph. The VM's are KVM in Proxmox in case it's relevant. regards *Roland *
