Multiattach is not a supported feature in OSP13.
Seems like this backport https://bugzilla.redhat.com/show_bug.cgi?id=1613486 is dependent on other issues below which are marked for Rocky. https://bugzilla.redhat.com/show_bug.cgi?id=1033180 https://bugzilla.redhat.com/show_bug.cgi?id=1033185 https://bugzilla.redhat.com/show_bug.cgi?id=1624971 Can we make sure all dependent issues are going to be fixed and backported to ensure that this feature will be supported?
I think it was dependent on 1623365 which is fixed in OSP13.
The overall multiattach feature backport is being tracked in 1624971 and we will consider this one only a bugfix to enable the option for this back-end and enable partner testing in the next Z stream. Here's the plan summary: Tech Preview for OSP-13 with customer and partner required actions: 1) Red Hat Support Exception required for Customer case that clearly indicates multi-attach use case (application) and staging/testing prior to production 2) Partners required to have cinder feature enabled in stable queens and ensure testing for partner back-end both upstream and on RHOS-13 erratta update with the support We know of at least a half dozen known patches and LPs that need to be backported to enable this for tech-preview on OSP-13 and that will be tracked in RBZ:1624971
