Hi, the intresting part is: [osd01][WARNIN] INFO:ceph-disk:Running command: /usr/bin/ceph --cluster ceph --name client.bootstrap-osd --keyring /var/lib/ceph/bootstrap-osd/ceph.keyring auth add osd.0 -i /var/lib/ceph/tmp/mnt.IkLtKp/keyring osd allow * mon allow profile osd [osd01][WARNIN] Error EINVAL: entity osd.0 exists but key does not match As it seems, there is already a key for "osd.0" in your auth list. You will have to remove the existing first and try again. -- Mit freundlichen Gruessen / Best regards Oliver Dzombic IP-Interactive mailto:info@xxxxxxxxxxxxxxxxx Anschrift: IP Interactive UG ( haftungsbeschraenkt ) Zum Sonnenberg 1-3 63571 Gelnhausen HRB 93402 beim Amtsgericht Hanau Geschäftsführung: Oliver Dzombic Steuer Nr.: 35 236 3622 1 UST ID: DE274086107 Am 05.04.2016 um 06:52 schrieb zainal@xxxxxxxxxx: > [osd01][WARNIN] INFO:ceph-disk:Running command: /usr/bin/ceph --cluster > ceph --name client.bootstrap-osd --keyring > /var/lib/ceph/bootstrap-osd/ceph.keyring auth add osd.0 -i > /var/lib/ceph/tmp/mnt.IkLtKp/keyring osd allow * mon allow profile osd > > [osd01][WARNIN] Error EINVAL: entity osd.0 exists but key does not match > _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
