Hi all,
going to deploy a test cluster and successfully deployed my first
monitor (hurray!).
Now trying to add the first osd host following instructions at:
https://docs.ceph.com/en/latest/install/manual-deployment/#bluestore
I have to note - however - that:
1.
--
copy /var/lib/ceph/bootstrap-osd/ceph.keyring from monitor node
(mon-node1) to /var/lib/ceph/bootstrap-osd/ceph.keyring on osd node
(osd-node1)
--
The source directory on monitor node (in my case named mon1) is empty;
however I have my keyring on osd host; I arranged to import the mon
keyring and mon map following the instructions here:
https://access.redhat.com/documentation/en-us/red_hat_ceph_storage/3/html/installation_guide_for_red_hat_enterprise_linux/manually-installing-red-hat-ceph-storage
2.
So I just run:
# ceph-volume lvm create --data /dev/sdb --cluster euch01
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 788c15be-7f1f-4151-b8c5-703e4a72361c
stderr: Error initializing cluster client: ObjectNotFound('RADOS
object not found (error calling conf_read_file)',)
--> RuntimeError: Unable to create a new OSD id
Where my cluster custom name is euch01 and volume to deploy OSD is
/dev/sdb; however my suspect is that the osd creation fails because on
the third "Running command" line I read "--cluster ceph" that is the
default cluster name - Note again: I specified my custom cluster name.
Any hint is strongly welcome.
Thank you very much for any help.
Francesco
Some side notes:
- Sorry, newbie here - a lot to learn -> Please be patient.
- With cephadm I arranged to run a test cluster in a very reasonable
time - However I don't like containerized solutions in this case due to
overhead that I feel quite stupid...
- Tried to deploy with ceph-ansible but installation crash and no
support from ceph-ansible developer... no problem: Trying to deploy
manually - More things to learn!
- Now to deploy my first monitor I did a collage of the RedHat and Ceph
original website because RedHat is pointed to deploy on RHEL and not on
other distros like CentOS (or debian); ceph.com seems to miss some
important steps that I've found on RH pages. Of course if someone has to
suggest a complete guide to deploy Pacific from a to z without
containers is strongly welcome.
