Use the block.db option without the device path but only {VG}/{LV}:
ceph-volume lvm prepare --data /dev/sda
--block.db vg/sda.db --dmcrypt
Zitat von tri@xxxxxxxxxx:
Hi all,
I'm having problem creating an osd using ceph-volume (by the way of
cephadm). This is on an octopus installation with cephadm. So I use
"cephadm shell" and then "ceph-volume" but got the following error:
root@furry:/var/lib# ceph-volume lvm prepare --data /dev/sda
--block.db /dev/vg/sda.db --dmcrypt
Running command: /usr/bin/ceph-authtool --gen-print-key
Running command: /usr/bin/ceph-authtool --gen-print-key
Running command: /usr/bin/ceph --cluster ceph --name
client.bootstrap-osd --keyring
/var/lib/ceph/bootstrap-osd/ceph.keyring -i - osd new
29d95564-733d-4f2a-a2c8-1bb9ceb5a14b
stderr: [errno 13] RADOS permission denied (error connecting to the cluster)
--> RuntimeError: Unable to create a new OSD id
if I pass the cluster ID, and use the correct key ring (using the
client.admin keyring), I got a bit further
root@furry:/var/lib# ceph-volume --cluster

stderr: Error initializing cluster client: ObjectNotFound('RADOS

--> RuntimeError: Unable to create a new OSD id
Any idea on how to get pass these errors? Thanks.
