Hi I relieved to have found a solution to this problem. The ansible script for generating the key did not pass the key to the following command line and sent therefore an empty string to this script (see monitor_secret). ceph-authtool /var/lib/ceph/tmp/keyring.mon.{{ monitor_name }} --create-keyring --name=mon. --add-key={{ monitor_secret }} --cap mon 'allow *' Now when this invalid key is being used to create the ceph file systems it seems to be copied to the location indicated below (/var/lib/ceph/mon/ceph-control01/keyring), and is crashing the ceph command below. Maybe a developer should have a look into this. It seems to me as if a base64 decoding went wrong in his case and crashes the process. Thanks anyway Cheers Daniel From: Daniel Wilhelm Hi
I am trying to install ceph with the ceph ansible role: https://github.com/shieldwed/ceph-ansible.
I had to fix some ansible tasks to work correctly with ansible 2.0.2.0 but now it seems to work quite well. Sadly I have now come across a bug, I cannot solve myself:
When ansible is starting the service ceph-mon@ceph-control01.service, ceph-create-keys@control01.service gets started as a dependency to create the admin key.
Within the unit log the following lines are shown:
May 19 11:42:14 control01 ceph-create-keys[21818]: INFO:ceph-create-keys:Talking to monitor... May 19 11:42:14 control01 ceph-create-keys[21818]: INFO:ceph-create-keys:Cannot get or create admin key May 19 11:42:15 control01 ceph-create-keys[21818]: INFO:ceph-create-keys:Talking to monitor... May 19 11:42:15 control01 ceph-create-keys[21818]: INFO:ceph-create-keys:Cannot get or create admin key
And so on.
Since this script is calling “ceph --cluster=ceph --name=mon. --keyring=/var/lib/ceph/mon/ceph-control01/keyring auth get-or-create client.admin mon allow * osd allow * mds allow *”
I tried to call this command myself and got this as a result: Segmentation fault (core dumped)
As for the ceph versions, I tried two different with the same result: · Ubuntu integrated: ceph 10.1.2 · Official stable repo: http://download.ceph.com/debian-jewel so: 10.2.1
How can I circumvent this problem? Or is there any solution to that?
Thanks
