LMDB Postfix caches support sharing; non-LMDB caches cannot be
shared at all.
To be precise: LMDB Postfix caches support shared access by readers
and writers. Other caches cannot be shared by writers or by
readers+writers. Read-only sharing is OK, but irrelevant for caches.
However, the Postfix LMDB client requires fcntl locks. If clusterfs
does not support fcntl locks, then things will blow up. If fcntl
performance sucks, use memcache without persistent backup.

We use couchbase cluster with memcached buckets to share postscreen
cache between cluster of postfix machines. We you use Couchbase , then
you run a proxy application to your bucket called moxi. It gives you one
common memcached shared between all postfix machines in cluster without
connecting them together, you only use moxi - proxy application to your
single memcache bucket.
