Description Vikhyat Umrao 2018-02-01 14:26:03 UTC
Description of problem:
Ceph installation fails when using NVME disk

The ceph-ansible fails to find the path to the NVME partition. It does not form the NVME partition path correctly. It is missing the "p1" suffix.

failed: [osd-node-1] (item=/dev/nvme0n1) => {"changed": false, "cmd": ["ceph-disk", "activate", "/dev/nvme0n11"], "delta": "0:00:00.060679", "end": "2018-01-31 11:04:07.468680", "failed": true, "item": "/dev/nvme0n1", "msg": "non-zero return code", "rc": 1, "start": "2018-01-31 11:04:07.408001", "stderr": "ceph-disk: Error: /dev/nvme0n11 does not exist", "std
err_lines": ["ceph-disk: Error: /dev/nvme0n11 does not exist"], "stdout": "", "stdout_lines": []}  

The task failing, belongs to this role: ceph-osd/tasks/activate_osds.yml.
The task name is: "- name: activate osd(s) when device is a disk"

The customer patched the installer in order to work, but It is a workaround.
This is how we changed the regexp of the Ansible task:

- name: activate osd(s) when device is a disk                                          
#command: ceph-disk activate  regex_replace('^(\/dev\/cciss\/c[0-9]{1}d[0-9]{1})$', '\\1p') 1                                                                    

command: ceph-disk activate " item p1"                                           
 - "unique "               
  changed_when: false                      
  register: activate_osd_disk              
	- not osd_auto_discovery               
	- not dmcrypt

This bug is for a NON-containerized installation. For containerized we have another bug - https://bugzilla.redhat.com/show_bug.cgi?id=1537980

Comment 5 Guillaume Abrioux 2018-02-16 07:33:09 UTC
The fix is included downstream from v3.0.23

Comment 16 Vasishta 2018-03-28 06:56:05 UTC
Worked fine with ceph-ansible-3.0.28-1.el7cp.noarch.

Moving to VERIFIED state.

Comment 23 Neil Levine 2018-06-08 16:38:55 UTC
Target release for this ticket needs fixing.

Comment 25 Vasishta 2018-07-16 05:13:05 UTC
Hi Ken, 

Yes, VERIFIED is the right status for the BZ.
