Hi Eugen, Thanks for the quick response! I'm probably doing things the more difficult (wrong) way 😉 This is my first installation of a Ceph-cluster. I'm setting op three servers for non-critical data and low i/o-load. I don't want to lose capacity in storage space by losing the entire disk on which the os is installed. The os disk is about 900Gb and I've partitioned 50Gb for the os. I want to use the remaining 850Gb as OSD. First I've created a new partition of 850Gb and changed the type to 95 (Ceph OSD). Then I tried to add it to the cluster with 'ceph orch daemon add osd hvs002:/dev/sda3', but I got an error. That's why I tried the lvm manual way. I know using a partition next to the os isn't best practice. But pointers to 'better practice' than what I describe above would be greatly appreciated.
