Hi,
assuming you're running Octopus the deployment guide [1] explains it
quite well.
To specify rocksDB/WAL devices you have to make use of "drive_groups" [2].

Zitat von Will Payne <will@xxxxxxxxxxxxxxxx>:
Hi,
Total newbie question - I'm new to Ceph and am setting up a small
test cluster. I've set up five nodes and can see the available
drives but I'm unsure on exactly how I can add an OSD and specify
the locations for WAL+DB.
Maybe my Google-fu is weak but the only guides I can find refer to
ceph-deploy which, as far as I can see, is deprecated. Guides which
talk about using cephadm / ceph only mention adding a drive but not
specifying the WAL+DB locations.
I want to add HDDs as OSDs and put the WAL and DB onto separate LVs
on an SSD. How?
Will
