It seems you are running into this: https://github.com/rook/rook/issues/11474#issuecomment-1365523469 You can check the output of the below command, and see if the disks are detected by the ceph-volume: ceph-volume inventory --format json-pretty Also try to add a specific device path to the above command for more detailed output if the device is not being detected successfully. Note that it's not a rook-specific issue. Cheers, Dongdong P Wagner-Beccard <wagner-kerschbaumer@schaffroth.eu> 于2023年12月4日周一 09:00写道：

Hey Cephers,

Hope you're all doing well! I'm in a bit of a pickle and could really use some of your power.

Here's the scoop:

I have a setup with around 10 HDDs. and 2 NVME's (+uninteresting boot disks) My initial goal was to configure part of the HDDs (6 out of 7TB) into an md0 or similar device to be used as a DB device. (the rest would be nice to use as an nvme osd) I made some clumsy attempts to set them up "right"

While the OSDs are getting deployed, they are not being shown back to the dashboard. The specific error when running `ceph orch device ls`: 'Insufficient space (<10 extents) on vgs, LVM detected, locked.' Given these, I have a few questions:

Are there specific configurations or steps that I might be missing when setting up the DB device with multiple HDDs? (rel; I currently try things like this https://paste.openstack.org/show/bdPHXQ0BMypWnZTYosT2/ ) Could the error message indicate a particular issue with my current setup or approach? If anyone has successfully configured a similar setup, could you please share your insights or steps taken?

Thanks a bunch!
