I think SAN is better for block access instead of file access (NAS)

Asunto: [ADMIN] Postgres on NAS/NFS
I am considering running a Postgres with the database hosted on a NAS via
NFS. I have read a few things on the Web saying this is not recommended, as
it will be slow and could potentially cause data corruption.
My goal is to have the database on a shared filesystem so in case of server
failure, I can start up a standby Postgres server and point it to the same
database. I would rather not use a SAN as I have heard horror stories about
managing them. Also they are extremely expensive. A DAS would be another
option, but I'm not sure if a DAS can be connected to two servers for server
failover purposes.
Currently I am considering not using a shared filesystem and instead using
replication between the two servers.
I am wondering what solutions have others used for my active-passive
Postgres failover scenario? Is a NAS still not a recommended approach? Will
a DAS work? Or is replication the best approach?
