Description Javier Coscia 2019-05-30 16:33:07 UTC

Document URL: 

 * https://access.redhat.com/documentation/en-us/red_hat_hyperconverged_infrastructure_for_virtualization/1.6/html/deploying_red_hat_hyperconverged_infrastructure_for_virtualization/task-config-rhgs-using-cockpit

Section Number and Name: 

 * 6 - Specify bricks

Describe the issue: 

* According to https://bugzilla.redhat.com/show_bug.cgi?id=1711959#c6 and https://bugzilla.redhat.com/show_bug.cgi?id=1711959#c7 we don't support VDO and LVM Cache. We don't say anything about this on our docs which could lead to an unexpected behavior if users configure LVM Cache and VDO at the same time.

Suggestions for improvement: 

* In my opinion, a note should be added into the mentioned link like we already have when saying do not use VDO and Thinp at the same time. Something similar could be added below the image in 6.

Hi Anjana,

Can you please point me to were exactly we document it?

I went to those guides, but couldn't find the message:
