Hi,
--
Can someone please explain this to me in layman's terms. How big a WAL drive do I really need?
I have a 2x 400GB SSD drives used as WAL / DB drive and 4x 8TB HDD's used as OSD's. When I look at the drive partitions the DB / WAL partitions are only 576Mb & 1GB respectively. This feels a bit small.
