Description John Harrigan 2018-11-17 21:29:42 UTC

Description of problem:
the ceph lvm batch mode and it's usage with ceph-ansible needs to be more fully documented, including examples of various hardware configurations. Examples should be provided for these configurations:
  * multiple HDDs with single NVMe
  * multiple HDDs and multiple NVMe's

Version-Release number of selected component (if applicable):
RHCS 3.2 

Installation Guide for RHEL
Chapter 3.2, table 3.2 needs to be updated to cover 'ceph lvm batch' mode

I read the preview links which cover the limited cfgs doc'd upstream.
I think we need to provide our customers more information on prescribed usage
for multiple NVMe configurations.

Specific ask was for 
> Examples should be provided for these configurations:
>  * multiple HDDs with single NVMe
>  * multiple HDDs and multiple NVMe's

Review link doesn't have example of single and multiple NVMe's configuration.  Please update the doc as requested in bz.

Comment 9 Tiffany Nguyen 2018-11-29 21:56:57 UTC

I have reviewed the doc.  Everything looks good except scenario with 2 NVMes and 4 HDDs.  Two bzs below were filed in this area:
 
 https://bugzilla.redhat.com/show_bug.cgi?id=1650306
 https://bugzilla.redhat.com/show_bug.cgi?id=1654441

I will wait for these issues to resolve and review the doc again to ensure we provide correct info to user.

Comment 10 Tiffany Nguyen 2018-12-05 17:13:29 UTC

Doc looks good for 2 NVMes scenario.  Support multiple NVMe installation according to best practices will be tracked in this bz:
