I'd be curious to hear what everyone thinks, though, and specifically about what NetApp recommends in Section 3.3 about putting data and WAL on separate volumes, which I believe contradicts what's been discussed in this email thread. yes, I've read the part about different volumes and I must say, I don't agree because I think it violates atomicity. Archived WAL is another thing, but PGDATA and pg_wal should IMHO always be located on the same volume, along with tablespaces, if any. Cheers, Paul
