Hi, can you paste this output:
ceph orch ls osd —export
Zitat von claas.goltz@xxxxxxxxxxxxxxxxxxxx:
Hi Community,
currently i’m installing an nvme only storage cluster with cephadm
from scratch (v.17.2.5). Everything works fine. Each of my nodes (6)
has 3 enterprise nvme’s with 7TB capacity.
At the beginning I only installed one OSD per nvme, now I want to
use four instead of one but I’m struggling with that.
Frist of all I set the following option in my cluster:
ceph orch apply osd --all-available-devices --unmanaged=true
As I understand this option should prevent cephadm to automatically
fetch new, available disks and deploying OSD daemons. But that seems
not to work.
If I delete and purge my OSD and zapping the disk with
ceph orch device zap ceph-nvme01 /dev/nvme2n1 –force
the disk came available for the cluster and seconds later it deploys
the same OSD ID than it has before. I checked that the old OSD was
completely removed and the docker container was not started.
My next try was to set:
ceph orch host label add ceph-nvme01 _no_schedule
purge the OSD
zapping the disk and following:
ceph orch daemon add osd ceph-nvme01:/dev/nvme2n1,osds_per_device=4
removing the _no_schedule flag
and again: the old OSD was recreated and not 4.
So where is my mistake?
Thank you!
