I would recommend a separate pg_wal filesystem with the record size to match the WAL page size; in my case 16k. I have keepthe default record size at 128k for the data volume and that configuration has worked well for supporting large DSS whileusing 16k data blocks. > On Mar 30, 2022, at 5:32 PM, Scott Ribe <scott_ribe@elevated-dev.com> wrote: > > I've read all the info I could find re running PG on ZFS: turn off full page writes, turn on lz4, tweak recordsize so asto take advantage of compression, etc. One thing I haven't seen is whether a separate volume for WAL would benefit froma larger recordsize. Or any other tweaks??? > > -- > Scott Ribe > scott_ribe@elevated-dev.com > https://www.linkedin.com/in/scottribe/ > > > > >
