Hi,I think you do not need do osd activate. I always just use osd prepare,and it works well most time. can you paste the output of these in host osd01: df -h ls -l /var/lib/ceph I think everything works well but it do not create the directory of /var/lib/ceph/osd/ceph-0 and do not mount /dev/sdc1 to this direcoty. I face this problem on one of my osd this day in virtual environment. Hope this can help you. 2016-04-08 18:38 GMT+08:00 Oliver Dzombic <info@xxxxxxxxxxxxxxxxx>: > 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 _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
