Description Mike Hackett 2019-12-20 19:32:12 UTC 
Description of problem:
The RHCS 3 Operations Guide details replacing a Journal disk but incorrectly provides a command which could be subject to incorrect interpretation.

Guide: 
https://access.redhat.com/documentation/en-us/red_hat_ceph_storage/3/html-single/operations_guide/index#replacing-a-journal-using-the-command-line-interface-ops

Step 6. Set the proper parameters on the new partition:
sgdisk --change-name=0:"ceph journal" --partition-guid=0:$OLD_PART_UUID --typecode=0:45b0969e-9b03-4f30-b4c6-b4b80ceff106 --mbrtogpt -- $NEW_DEV_PATH

This is actually specifying the partition-guid as 0 in the above command, if we provide this we need to detail that this is an example that that --partition-guid=0 should reflect the partition guid being replaced.

Please see https://access.redhat.com/solutions/2328701 for more details.


Version-Release number of selected component (if applicable):
RHCS 3.3


Actual results:
Could impact OSD's and/or disks not intended to be modified.

Expected results:
Should modify correct partition.
