[linux-lvm] Local Cache on CLVM

I have a query on Caching on CLVM.
Consider a clustered storage system with one common RAID Array and 2
Servers. The servers are configured in an active-passive configuration
using Pacemaker and CLVM.
Each server has a PCIe NVMe Card in it.
Is there any way I could use the PCIe NVMe card for caching?
I understand that if failover happens, the cache may be empty or the
content different on the failed-over server. But that would only mean
that it would take some time to refresh the cache again. I am okay
But is there any way to make it look like its the same cache drive on
both the primary and failover servers?
