[SOLVED] Thread 'Add WAL/DB to CEPH OSD after installation.'

Apr 30, 2024

Hi there.
I had have created a Proxmox CEPH Cluster with 3 servers and each one has 4 SSD DC Disk. Is it possible to add separated NVME to do WAL/DB "AFTER" everything is up and running, let's say a couple of weeks after?

Thanks

But when I add DB to exists OSD, weight is still the same:

And for example OSD that was redeployed, have weight calculated by summary of size DATA and DB.

As I understand it, I can correct it with ceph crushmap modification?
