This behaviour changes wrt ansible workflow in extending the logical volume group. There is nothing changed at LVM layer. Do we still need customers to be aware of this change ?

Probably it was referenced from another bug. Are you saying, that there is no change for the user in this configuration and all is done via the software, so documentation is not needed? I found the customer bug: bz#1728225. It is still open and it has KCS attached: https://access.redhat.com/solutions/4575941. Probably what I meant here is that this should be in the official documentation, rather then having the deployment fail and requiring opening a case because of that. Sas, please review the KCS and tell me why you think it should not be in teh official documentation?

Marina, Yes, the changes as mentioned in the Knowledge Base Article is now solved. Cockpit handles it intelligently, when the user tries to create LVM cache, it includes the Original disk also. So the changes, no longer needs to be documented. The bug bz#1728225 was there to solve different purpose, where when the disk block size of 'Fast Disk' or 'SSD' doesn't match with the disk block size of 'Slow Disk' or HDD, it will throw error and for that the workaround is to deactivate and activate VG # vgchange -an gluster_vg_xxx # vgchange -ay gluster_vg_xxx
