Re: [ceph-users] My OSDs are down and not coming UP

I made small leap ahead.

Not it seem to be some problem with autentication may be.

Just try putting something like the following in ceph.conf:

[global]
mon_host =xxxx:xxxx:2:1612::50 xxxx:xxxx:2:1612::30
mon_initial_members = node-1 node-2

Also, I just noticed you have two MONs? It should always be an odd number. Not sure if they can ever get quorum now?

I'm deploying ceph cluster manually following different guides. I didn't use ceph-deploy yet.

It should be monitor host names..If you are deploying with ceph-deploy it should be added in the conf file automatically..How are you creating your cluster ?

Did you change conf file after installing ?

    Has the cluster ever worked?
    Are you sure that "mon initial members = 0" is correct? How do
    the OSDs know where to look for MONs?
