[ceph-users] ceph-bluestore-tool failed

Hi,  thanks.

Tried with path option but gets same error:

# ceph-bluestore-tool show-label --path /var/lib/ceph/osd/ceph-2
inferring bluefs devices from bluestore path
2018-11-01 15:57:53.395 7f9f91adca00 -1 auth: unable to find a keyring on /etc/ceph/ceph.client.admin.keyring,/etc/ceph/ceph.keyring,/etc/ceph/keyring,/etc/ceph/keyring.bin,: (2) No such file or directory

failed to fetch mon config (--no-mon-config to skip)


Copying /etc/ceph/ceph.client.admin.keyring from admin server to osd host then it works, although it seems it's not the right way to do that?

}

Would you help?
Thanks again.

You might want to try --path <path_to_osd_dir> option instead of --dev one.

Hi all,

We deployed a testing mimic CEPH cluster using bluestore.    We can't run ceph-bluestore-tool on OSD with following error:

-------
# ceph-bluestore-tool show-label --dev *device*

Shall we run this command on admin server with corresponding keyring ?   But ceph-bluestore-tool is in ceph-osd package and doesn't exist on admin server.
Did we miss anything?

Thanks a lot.
