Re: My OSDs are down and not coming UP

["Ing. Martin Samek" <samekma1@xxxxxxxxxxx>]

I thank both of you. Now I have 3 OSDs UP and running. Messy ceph.conf was the issue :)

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 ?

Hi,

No, never. It is my first attempt, first ceph cluster i try ever run.

im not sure, if "mon initial members" should contain mon servers ids or hostnames ?

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?

Hi,

network is OK, all nodes are in one VLAN, in one switch, in one rack.

There is no firewall installed or configured.
