I was thinking about using RAID5 to keep the disk redundancy even during

In just the last week I've seen at least two failures as a result of

With your stated capacity, you're looking at a mere 16TB with rf3. You'll
need to look into slightly more capacity or w

Drop RAID5 and create one OSD per harddisk.
If you need to store small files consider how your applications
communicates with the storage cluster
Hi.
I have to create a new Ceph cluster with 3 nodes with 4 hard drives in

Can you advise me a good configu
