Re: ceph-deploy mon create failing with exception

[Martin Palma <martin@xxxxxxxx>]

Hi,

from what I'm seeing your ceph.conf isn't quite right if we take into account you cluster description "...with one monitor node and one osd...". The parameters "mon_inital_members" and "mon_host" should only contain monitor nodes. Not all the nodes in you cluster. 

More over you should provide in the "public_network" parameter also the netmask of the network.

What where the exact commands you performed before the step 5? DNS and hostname lookup does work correctly?

Best,

Martin

I am installing a ceph-cluster with one monitor node and one osd. I am following the document:

http://docs.ceph.com/docs/v0.86/start/quick-ceph-deploy/

During the step 5: Add the initial monitor(s) and gather the keys (new in ceph-deploy v1.1.3),

I am getting the following exception:

[ceph-mon1][ERROR ] admin_socket: exception getting command descriptions: [Errno 2] No such file or directory [ceph-mon1][WARNIN] monitor: mon.ceph-mon1, might not be running yet [ceph-mon1][INFO ] Running command: sudo ceph --cluster=ceph --admin-daemon /var/run/ceph/ceph-mon.ceph-mon1.asok mon_status [ceph-mon1][ERROR ] admin_socket: exception getting command descriptions: [Errno 2] No such file or directory [ceph-mon1][WARNIN] monitor ceph-mon1 does not exist in monmap

Just for reference my ceph.conf is as follows:

[global]

fsid = 351948ba-9716-4a04-802d-28b5510bfeb0

mon_initial_members = ceph-mon1,ceph-admin,ceph-osd1

mon_host = xxx.yyy.zzz.78,xxx.yyy.zzz.147,xxx.yyy.zzz.135

auth_cluster_required = cephx

auth_service_required = cephx

auth_client_required = cephx

filestore_xattr_use_omap = true

osd_pool_default_size = 2

public_addr = xxx.yyy.zzz.0

I tried to understand all the questions related to same on ceph user mailing list but there is no precise solution I found for this problem.

Can anyone help me on this?

Thanks & Regards
