RAID-Z 1 ZFS - CEPH

[ChrisJM]

Hello,

I have 2 SSD's in each the servers and installed proxmox as RAID-Z 1 then when i go to setup CEPH OSD i have "No Disk Unused"

Is there a way around this? i want RAID 1 for the redundancy, and dont want to spend over £1000 for more SSD's

Is there a fix for this?

No. You need a spare disk.

Try to create Ceph mannualy on zvol.

Doable, but don't. This should only be done to test how ceph works, but will be nowhere near usable in production.

Let him try it.
