If you want to be directly setting up the OSDs using ceph-volume commands (I'll pretty much always recommend following https://docs.ceph.com/en/latest/cephadm/services/osd/#dedicated-wal-db over manual ceph-volume stuff in cephadm deployments unless what you're doing can't be done with the spec files), you probably actually want to use `cephadm ceph-volume -- ...` rather than `cephadm shell`. The `cephadm ceph-volume` command mounts the provided keyring (or whatever keyring it infers) at `/var/lib/ceph/bootstrap-osd/ceph.keyring` inside the container, whereas the shell will not. So in theory you could try `cephadm ceph-volume -- lvm prepare --bluestore --data ceph-block-0/block-0 --block.db ceph-db-0/db-0` and that might get you past the keyring issue it seems to be complaining about.

Hi all! I;ve faced an issue I couldnt even google. Trying to create OSD with two separate LVM for data.db and data, gives me intresting error

And here is output which shows my created volumes
``` root@ceph-uvm2:/# lvs LV VG Attr LSize Pool Origin Data% Meta% Move Log Cpy%Sync Convert block-0 ceph-block-0 -wi-a----- 16.37t
db-0 ceph-db-0 -wi-a----- 326.00g ```
CEPH was rolled out by using cephadm and all the commands I do under cephadm shell
I have no idea what is the reason of that error and that is why I am here.
Any help is appreciated. Thanks in advance. _______________________________________________ ceph-users mailing list -- ceph-users@ceph.io To unsubscribe send an email to ceph-users-leave@ceph.io
