Not really. This person should learn to do their own research. They apparently need it.

It is if your client certificates are individualized by user, which they should so you can properly revoke client. certificates

Yes it’s a forum. But just because I corrected your error doesn’t mean I am obligated to do a whole fucking write up for you or go to google myself for you. Grow up.

Google?

None of these are client certificates btw. These are just ways to have your server use TLS encryption with any client that connects but it offers no authorization. If you want authorization with client certificates you need to implement mTLS (Mutual TLS).

Also a no-no. ZFS RAIDz2 is what you want.
