Re: ERROR: missing keyring, cannot use cephx for authentication

UUID strings  in the file /etc/fstab refer to devices.  you can retrieve UUID using command blkid, for instance:
# blkid /dev/sda1
/dev/sda1: UUID="1bcb1cbb-abd2-4cfa-bf89-1726ea6cd2fa" TYPE="xfs"

How did you get the UUIDs without mounting the osds?
Thanks

Hi all, I did HA failover test shutting down 1 node and I see that only 1 OSD came up after reboot:

[root@geminis ceph]# df -h

If I run service ceph restart I got this error message…

I have ceph.conf and ceph.client.admin.keyring under /etc/ceph:

[root@geminis ceph]# ls /etc/ceph
ceph.client.admin.keyring  ceph.conf  rbdmap  tmp1OqNFi  tmptQ0a1P

does anybody know what could be wrong?

Thanks
