I’m trying to use ceph for docker swarm cluster, but I’m trying to get my head around how it works. I’m familiar with computers and how local hard drives work.
My setup is a master and 3 nodes with 1Tb nvme storage.
I’m running Portainer and Ceph dashboard. The ceph dash shows the OSD’s.
I want to run basics- file downloads, plex, etc.
- Should I run the nvme in stripe or mirror mode? What if the network is a point of failure, how is it handled?
- How do I access the drive from a folder/file structure point of view? If I want to point it in the yaml file when I start a docker container, where do I find the /mnt or /dev? Is it listed in the ceph dashboard?
- Does ceph auto manage files? If it’s getting full, can I have it auto delete the oldest file?
- Is there a ELI5 YouTube vid on ceph dashboards for people with ADHD? Or a website? I can’t read software documentation (see ADHD wiki)
