How to set OSD journal device on a dedicated block device in Ceph barclamp.

This document (7021169) is provided subject to the disclaimer at the end of this document.

Environment

SUSE Cloud
SUSE Enterprise Storage 4

Situation

When applying Ceph barclamp after having set a dedicated block device for an OSD (Object Storage Daemon) journal in raw mode the setting is ignored:

"osd": {
  "min_size_gb": 20,
  "journal_size": 8192,
  "journal_devices": [
    "vde"
  ],
  "use_ssd_for_journal": false

Resolution

Go back to the crowbar web ui, Barclamps, Ceph, click "raw" and in the raw json mode set the full path to the block device:

"osd": {
  "min_size_gb": 20,
  "journal_size": 8192,
  "journal_devices": [
    "/dev/vde"
  ],
  "use_ssd_for_journal": false

Ideally, the path should be the symlink from /dev/disk/by-id/<device id> pointing to your device, which is persistent across reboots.

Finally apply Ceph barclamp.

Cause

Ruby code on the admin node /opt/dell/chef/cookbooks/ceph/recipes/osd.rb requires the full path to the device, specifying only the device name is  not sufficient.
