Feature #23000

- Status changed from New to Need More Info
Would you mind explaining what is the use case that requires multipath instead of just relying on LVM? How is it that LVM doesn't solve the multipath use case?
We have external storage (eg powervault) exporting disks through redundant controllers, resulting in multiple access paths we aggregate to a multipath device for high availability
You can still be able to configure LVM to use the multipath devices to create logical volumes though. No? ceph-volume will not attempt to configure LVM
in a machine, so some manual configuration would be needed here.
If you are feeding ceph-volume LV's then this check will never be performed. I can see how this would be problematic if it is being attempted to use partitions directly or devices so that ceph-volume can create the LV's for you.
I can't guarantee that just this one change would work to fully support multipath devices (we would need to implement extensive functional testing). Would the alternative of just using LV's for your setup work?
