Re: [ceph-users] how to enable MDS service in a running Ceph cluster

[Sebastien Han]

Hi, * Edit `ceph.conf` and add a MDS section like so:   [mds]   mds data = "">   keyring = /var/lib/ceph/mds/mds.$id/mdsi.$id.keyring   [mds.0]     host = {hostname} * Create the authentication key (if you use cephx):  $ sudo ceph auth get-or-create mds.0 mds 'allow rwx' mds 'allow *' osd 'allow *' > /var/lib/ceph/mds/mds.0/mds.0.keyring * Eventually start the service  $ sudo service ceph start mds.0  === mds.0 ===  Starting Ceph mds.0 on ceph...  starting mds.0 at :/0 Cheers. –––– Sébastien Han Cloud Engineer "Always give 100%.

I have built a set up  to try using RBDs, and it works brilliant.   I haven’t enable MDS service, because I think I do not need it at that time. But now, I want to try Ceph FS on the same cluster.   The question here is:  I already have some data stored in RBDs. Is there a way to enable MDS in the running Ceph cluster?   Thanks. -chen   _______________________________________________ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
