Thanks Olivier and Scot for your inputs!
Another data point I would like to share is that VMs will be built in Azure Cloud with Azure Managed Storage and Locally redundant storage (LRS) option with a remote DR as well.
LVM or ZFS would still be a good option to allow easy storage/disk management like add, resize or remove disks while PostgreSQL services are up?
Is equal data distribution a challenge on LVM/ZFS disks?
I would not call data distribution a challenge, but something to be aware of. If LVM has 3 disks in a pool it will, by default, use all of disk 1, then use all of disk 2, then use all of disk 3. The reason for that is with the default you can add new disks one at a time. With striping you must add new disks equal to the number of stripes. Either way I would still advise use of LVM.
