Bug 1510470

Created attachment 1348967 [details]
osds.yml

I should add that this environment had several install attempts before and cleaned with purge-site-docker.yml. The PARTUUID that the OSDs are looking for however stay the same. The fetch directory is cleaned between runs.
The problem persists even when changing to collocated setups.

This is not something we see in our CI.

Can we access this env?
Thanks!

Could you provide the full playbook run log?

Thanks

I tried to reproduce your issue with ceph-ansibe v3.0.9 and ceph-3.0-rhel-7-docker-candidate-61072-20171104225422 container image, the deployment worked fine.

OSDs are UP:

I think your multiple attempts to deploy have probably broken something.
I couldn't reproduce your issue, CI and QE didn't catch this issue as well. Could you retry to deploy from scratch? As Sebastien asked, any chance to access your env?

Thanks!

@Guilaume - this might well be the case. I will send you and leseb the credentials of the environment. It's AWS-based. I could retry to deploy from scratch to, but honestly I don't see what could cause this. I suggest we work in parallel. I will try to re-deploy from scratch and you can try to re-deploy in my environment see where it's choking up. This behavior will likely effect others that run in https://bugzilla.redhat.com/show_bug.cgi?id=1510555 - which is the reason I had to re-deploy so many times.

Hi Daniel,

the issue here is in purge-docker-cluster.yml playbook.
You tried several times to deploy your cluster; the first time, the osd disk prepare process produced some logs that are used later in ceph-ansible to retrieve journal partition uuid, these logs are supposed to be generated [1] only at initial deployment because they come from the prepare containers logs, if we lose these containers for any reason (reboot or anything else) we can't generate these logs again.

upstream PR: https://github.com/ceph/ceph-ansible/pull/2152

Hi Daniel, 

Tried setting up OSDs with dedicated journals (both dmcrypt and non-dmcrypt) using latest builds, 

Container image - ceph-3.0-rhel-7-docker-candidate-36461-20171114235412
Ceph-ansible - ceph-ansible-3.0.11-1.el7cp.noarch

(Because of test environment constraint only two journals (of 2 OSDs) were on dedicated disk)

Initialization and purging were tried thrice back to back on same set of nodes with node reboot after initializing cluster each time. All these time (both Initialization and after reboot) OSDs came up and were running as expected, thus it looks good to me.

Can you please let me know your views on steps followed as part of the bug fix verification ?

Vasishta
