@nixCraft nearly all suitably encrypted. No FDE.

OpenZFS encryption for:

* the sensitive part of a mobile hard disk drive

* three low-spec USB memory sticks that add around 145 GiB persistent removable L2ARC to a circa 2014 HP ZBook with 32 G memory and a ~1 TB internal HDD.

GELI for 16 G swap.

GELI for 915 G /

tmpfs for /tmp/

「… blocks in the L2ARC have the exact same on-disk representation as they do in the main pool. …」

geli(8) <man.freebsd.org/cgi/man.cgi?qu> – automatically configured when FreeBSD was installed.

tmpfs(4) <man.freebsd.org/cgi/man.cgi?qu> (FreeBSD 15.0-CURRENT)

@lispi314 @icedquinn @dushman @mel @lanodan @a1ba Eeyupp...

#L2ARC is the cache to use on #ZFS, and before that going with the 1:1024 rule (1GB RAM for 1TB of ZFS size) will greatly improve performance...

More won't unless one is pushing the limits of the drives but goin less will hurt it very much and I'd only violate that rule when it's only about transplanting data from an old ZFS to a new one "offline" (which means there should only be like 1 active copy process and nothing else touch either ZFSes)...
