Re: new installation

Yes of course...

iptables -F (no rules) = the same as disabled
SELINUX=disabled

As a testing ground, I use VBox. But I think it should not be a problem.
 

Firewall? Disable iptables, set SELinux to Permissive.

Hello,

    osdmap e10: 4 osds: 2 up, 2 in

What about following commands :

# ceph osd tree

# ceph osd dump

You have 2 OSDs on 2 hosts, but 4 OSDs seems to be debined in your crush map.

Regards,

Pascal

Hi ALL,

I've created 2 mon and 2 osd on Centos 6.5 (x86_64).

I've tried 4 times (clean centos installation) but always have health: HEALTH_WARN

Never HEALTH_OK always HEALTH_WARN! :(

# ceph -s

What am I doing wrong???
