Hello guys, a little update that let me more confused

I reinstalled the FreeBSD with 4k pages using the sysctl
vfs.zfs.min_auto_ashift = 12 and no errors after a lot of stress I put on
it.
One thing that I noticed is that with the pool as 4k, the disk fill up very
fast, recompiling the kernel used my 8GB space and didn't even completed.
But now I don't know if the 4k is the correct answer or if this just delays
the problem as the pages are bigger.
