Question regarding SSD and 4k format on SSD for ZFS

Post by crowi »

Hi community,

I am confused because I found different instructions how to create partitions for ZFS on SSD.
Is it necessary to place the 4k instruction in gpart or not?
i.e.
this command

Code: Select all

gpart add -a 4k -t freebsd-zfs -s xxG adax
or this one

Code: Select all

gpart add -s xxG -t freebsd-zfs adax
both were mentioned and I would like to know which one is the right.

Thanx,
Crowi
