What is supposed to happen: - ceph-deploy osd create HOST:DIR will create a symlink in /var/lib/ceph/osd/ to DIR. - admin is responsible for mounting DIR on boot - sysvinit or upstart will see the symlink to DIR and start the daemon. It is possible that the osd create step also isn't triggering the daemon start at the appropriate time. Sorry, this isn't as well tested a use case. s > > Ilja > > > -----Original Message----- > > From: ceph-users-bounces@xxxxxxxxxxxxxx [mailto:ceph-users- > > bounces@xxxxxxxxxxxxxx] On Behalf Of Alvaro Izquierdo Jimeno > > Sent: Thursday, June 06, 2013 2:26 AM > > To: John Wilkins > > Cc: ceph-users@xxxxxxxxxxxxxx > > Subject: Re: Problems with OSDs (cuttlefish) > > > > Hi John, > > > > Thanks for your answer! > > > > But Maybe I haven?t install the cuttlefish correctly in my hosts. > > > > sudo initctl list | grep ceph > > -> none > > > > No ceph-all found anywhere. > > > > Steps that I have done to install cuttlefish: > > > > sudo rpm --import > > 'https://ceph.com/git/?p=ceph.git;a=blob_plain;f=keys/release.asc' > > sudo su -c 'rpm -Uvh http://ceph.com/rpm-cuttlefish/el6/x86_64/ceph- > > release-1-0.el6.noarch.rpm' > > sudo yum install ceph > > > > > > Thanks a lot and best regards, > > ?lvaro. > > > > > > > > > > -----Mensaje original----- > > De: John Wilkins [mailto:john.wilkins@xxxxxxxxxxx] > > Enviado el: jueves, 06 de junio de 2013 2:48 > > Para: Alvaro Izquierdo Jimeno > > CC: ceph-users@xxxxxxxxxxxxxx > > Asunto: Re: Problems with OSDs (cuttlefish) > > > > You can also start/stop an individual daemon this way: > > > > sudo stop ceph-osd id=0 > > sudo start ceph-osd id=0 > > > > > > > > On Wed, Jun 5, 2013 at 4:33 PM, John Wilkins <john.wilkins@xxxxxxxxxxx> > > wrote: > > > Ok.
