I'm trying out NetBSD-9 with ZFS on raspberry pi 3. I have 128GB USB SD card which has ZFS setup. Noticed that sometimes when under heavy use something goes wrong and pgdaemon spins on CPU 100% all the time. Not sure if this is something to do with small amount of RAM on this machine. Are there any tunables like in FreeBSD vm.kmem_size="330M" vm.kmem_size_max="330M" vfs.zfs.arc_max="40M" vfs.zfs.vdev.cache.size="5M" that make ZFS play nice when low on RAM? Looked at "sysctl -a" but there are only kstat parameters, I assume they are only for statistics and don't affect run-time?
ZFS on Raspberry Pi? Nope. Not enough memory. Stick to FFS. Even a Pi 4 still doesn't have enough, unless all you want to use it for is run ZFS and NOTHING else.
